Converting From Oil Furnaces to Natural Gas In NE USA States Means Adding Gas Safety Devices, Too.

by Barbara 4. December 2014 09:04

Question about safety issues when converting from oil heat to gas heat.

Q: "A natural gas shale line from Marcellus Shale gas in Pennsylvania may extend into the Northeastern states in the next year, if approved (Quote from CBS 12/3/2014) We currently are using oil heat. Replacing the furnace with natural gas will save us a lot of money. How can we avoid the health risks associated with natural gas?"Thanks Tom.

Answer: Continue using carbon monoxide alarms and smoke detectors as you have been doing, remembering to test them monthly and change batteries once a year. I would also suggest you add a Scentry III Gas Shut Off system on your main line into the home as well as Safe-T-Alert Combustible Gas Alarm or a Safety Siren III natural gas alarm near your natural gas appliances such as ranges, fireplaces, etc.

With the Scentry III GFRAB, you can add additional remote sensors, a battery back-up and a connection to a home monitoring system if you have one or plan to get one.

Remember that natural gas is lighter than air and "puddles" at the ceiling above the appliance using it. If near an open stairway, the gas will go to the top of the stairway.

An annual furnace tune up with filter change is needed with gas furnaces as well as with oil. If you want the best disposable furnace filters, use the 4 inch or 1 inch Safe Home filters.

Thanks for your questions.

Sincerely,

Practical Ideas to Reduce Heating and Cooling Bills Now and In the Future

by Barbara 4. February 2014 06:37

Question about how to reduce my energy bills without spending a lot of money.

Q: "My gas bills this winter almost doubled with the very cold weather. Can you give me some ideas about how to reduce my bills without being cold? Thanks. Phil"

Answer: First, contact your gas company to learn if they have a one time free energy audit available to customers. If not, I suggest you contact several insulation contractors in your area to give you their opinions about the R values in your attic and side walls. You may choose not to add additional insulation. With some rebates available in some areas, adding insulation may not be as expensive as you believe.

Next, check for air leakage from your unused electrical outlets that are on the outside walls of your home. Safe Home sells a variety of plugs and covers to reduce the leakage. For examples, look at the electrical outlet covers and sliding door outlet covers such as CoverPlug Duplex Outlet Cover for Electric Outlets, the Plug Guard Energy Saving Safety Outlet Cover, the IVORY STD 3-Prg 1 Screw Outlet Cover,6/PK, the Kiddy Cop Outlet Covers, Leviton 12777, 12/Box, or the Sockit Lockets.  We installed the Care Cover outlet covers one bitterly cold January years ago and learned how much cold air was blocked from entering our home.

If you choose outlet plugs, I suggest you purchase insulating covers that install behind each electrical outlet. To install, remove your current outlet cover, push the insulation around the plugs and replace the liner and the outlet plugs.

Use insulating foam around all water lines into your home. Make sure the "flaps" seal tightly on exhausts from clothes dryers.

Purchase a set back thermostat for your furnace. Many utility companies have a rebate to help pay for this unit.  Do remember that setting the temperature back means that time is required to get the temperature to a comfortable level. We learned in June 2013 that our original furnace was undersized: the new one comes up to daytime temperatures much faster. We keep our nightime temperature set at 68 degrees and daytime at 72 degrees. The natural gas fireplace keeps the family room comfortable on the below zero days and nights.

Change your furnace filters regularly. Choose a MERV rating that works with your furnace. Too high of a MERV rating means you'll not get much air through your filter. Safe Home filters have two layers of filtration. When the white layer gets gray, it is time to change the filter. The second layer filters out odors and chemicals; the first, dirt, dust and pollen. Safe Home filters come in one inch sizes that are self-sealing due to an internal frame and in 4 inch filters that have a self-sealing perimeter.

Use supplemental electric heaters where you need them. We suggest the ECO SAVE Ceramic Heater that is compact and efficient and used only 750 watts of electricity. If your feet get cold while the rest of you feels comfortable, then consider the Toasty Toes Heated Footrest.

If you have the money and your furnace is 15 or more years old, consider replacing the furnace. Make sure you get at least three bids. If the BTU ratings vary a lot, get another bid or two. YOu don't want an oversized furnace nor an undersized one (like the one we had for over 20 years).

We replaced both AC and the main furnace this summer with next to the highest efficiency units. (Total cost was $5400 less the rebates.) The new furnace is two stage, i.e. two blower speeds. We got rebates from both the gas and electric companies. Also we did not choose the most expensive units available. Sometimes you have to choose between a few thousand dollars and paying your HVAC person annual AC and heating tune-ups.

This past month we did use an electric ceramic heater set at 65 degrees F in our tiled bathroom and another one in the kitchen (ceramic flooring). That took the chill off in those rooms. Unfortunately, our new kitten has yet to learn to keep his claws in. So the insulated window shades remain up even in the cold weather. (A toss up between ripped shades and more insulation or keeping Buddy from climbing them.)

If you have other questions, please contact us.

Sincerely, Barbara

Replace Safe-T-Alert RV30-441 Propane Alarm With a Safe-T-Alert 35-741,CO Alarm/Gas Alarm Combo

by Barbara 24. October 2013 06:05

Question about replacements for CCI Controls Propane Alarm 7770.244.

Question: "What 12 Volt RV gas alarm can replace my CCI Controls 7770.244 that is beeping? I also need a new carbon monoxide alarm." Thanks. Steve.

Answer: Safe-T-Alert has two units, the Safe-T-Alert 30-441 and the Safe-T-Alert 35-741. Both are surface mount units.  If you want to add more carbon monoxide detection, I suggest the new combination units, the 35-741 which comes in a black surface mount RV alarm and a white unit. The 30-441, gas only monitor with alarm, comes in brown and white. Both have approximately the same dimensions as the old CCI units.

If your carbon monoxide alarm is hard-wired, please look at these two units, the Safe-T-Alert 65-542 and the Safe-T-Alert 65-541 . The first is flush mounted, i.e. the rear of the unit goes into your RV wall. The second is flush mounted. These are available in white, brown and black.

If your carbon monoxide alarm is battery powered, consider replacing it with the Costar 9RV which meets all the RVIA specs for humidity and temperature ranges. For more protection, install the Costar 12RV-DB which hooks to both your coach 12 volt system and to your RV 12 volt engine battery. This unit draws from the unit with the most power and also has a 9 volt battery back-up.

And make sure your smoke alarm was replaced within the past 5 years as well. Nothing more annoying than being woken in the middle of the night by a false alarm! The Safe-T-Alert 775 is a 9 volt battery powered unit that is UL listed and approved for RV use.

Thanks for your question.

Sincerely,

Barbara

UL and CSA Require RV CO and Propane Gas Alarms Stop Working in 3-5 Years

by Barbara 28. April 2012 10:03

Question about life span of carbon monoxide and propane monitor/alarms in RV's and trailers.

Q: "My RV has the original carbon monoxide and propane monitors. When should I replace them? Thanks Tom."

Answer: Safe Home recently learned that all newly manufactured 12V propane alarms and carbon monoxide alarms, whether combination alarms or single alarms, must include an internal shut-down system. The Safe-T-Alert brand we sell has an internal warning system that beeps and flashes when the sensor is dying and then beeps and flashes when the unit shuts down from sensor failure. Typical life is 3 to 5 years unless the sensors are exposed to aerosols such as spray deodorants, cooking sprays, cleaners, etc. Note the date of installation on the outside of the unit with a sticker or log into your owner's manual so you won't be awakened in the middle of no where with the bad news that your units are or have failed.

Below is the information we received from Safe-T-Alert in April 2012 to share with customers.

CARBON MONOXIDE & PROPANE ALARM REPLACEMENT NOTICE: Note to Customers:

All Safe-T-Alert Propane and Carbon Monoxide Alarms that are 5 years old and older are beyond their Mandatory Replacement Time and MUST be replaced.

Background: Underwriters’ Laboratories (UL®) Carbon Monoxide Standard UL 2034 and Canadian Standards Association (CSA®) CSA 119.2 now require that all Carbon Monoxide alarms be designed to stop service in 3 to 5 years . UL and CSA have determined that Carbon Monoxide alarms have a limited life. Propane alarms use similar sensors and UL will require the same service life in the near future.

ALL MTI Propane and Carbon Monoxide alarms which are over five (5) years old MUST be replaced. The following Safe-T-Alert Carbon Monoxide Alarm Models MUST be replaced: SA-4, SA-5, 50-541 and 50-542. Models 60-541 and 60-542 over five (5) years old MUST be replaced.The following Safe-T-Alert Propane Alarms Models MUST be replaced: SA-7 and SA-8. Models 30-441,30-442, 40-441 and 40-442 that are over five (5) years old MUST be replaced.

Important! Only install CO and Propane alarms that are UL or CSA listed for Recreational Vehicle Use.

Thank you for your question.

Sincerely,

Barbara

 

 

California Law Effective July 1, 2011 for Installation of Carbon Monoxide Alarms in All Single Family Homes

by Barbara 27. June 2011 14:13

Question about approved carbon monoxide alarms for use in California.

Q: "Do you sell carbon monoxide alarms on the "List of California State Fire Marshal Approved Carbon Monoxide Alarms"? The law now requires these be installed in every single family dwelling. How quickly can they be shipped. Thanks. Steve."

Answer: Yes, we do sell several approved carbon monoxide alarms. Unless you are ordering a large quantity of units, we ship within 3 business days using either the postal service or UPS.  The Fire Marshall list expires in July 2012.

Costar Models:

Kidde and Kidde Nighthawk Carbon Monoxide Alarms:

If there are other approved Kidde units you would like pricing on, please let us know. We are able to discount larger quantities of these products. Most come in case of 12 or 24 units. Remember you need to install at least one carbon monoxide alarm on each level of your home and one CO alarm in every bedroom where the door is shut at night. Do remember that if you have gas burning appliances like ranges, stoves and furnaces that you also should add gas alarms for propane or natural gas to protect against explosions and fires.

Thank you for bringing this new law to our attention.

Sincerely, Barbara

WA State Requires Automatic Gas Valve Shut Off System in New Homes

by Barbara 16. April 2011 08:06

Question about the Scentry III GFRAB Home LP/Natural Gas Detector.

Q: "How fast can you get a Scentry III system to me? Washington State now requires an automatic gas shut off system be installed before an occupancy permit can be issued for a new home who has a propane furnace in the basement. We are desperate. What I need are several components, the Scentry III GVL .75 Inch Gas Valve and the Scentry III GFRAB Home LP/Natural Gas Detector. My plumber is ready to install it. Our home rental is almost up. We are desperate. We have propane in this new home since it is in the country. Thanks. Robert."

Answer: Yours is the third sale to Washington state in the first two weeks of March. That is encouraging news to the building trade as the economy begins to improve.

The other sales were to Olympia, Seattle and to Bainbrdige Island. You live in Port Orchard. We appreciate that you've offered your contractor our contact information since we do have discounts available on packages of 6 units. We can next day air the units to you.

All customers ordered the 3/4 inch gas valve and the GRAB model. For those who are unfamiliar with these units, the Scentry models are all made in the USA, in fact in Davenport, IA. There is also a 220VAC model available for those who live outside the USA. All gas valves throughout the world are essentially sized the same so a USA made valve works fine in countries where 220V is the standard.

You should consider adding additional gas sensors if you have a propane range or propane fireplace. I know you've shared that both your water heater and furnace are in the same utility room.

In your case, you say that intermittent power failures are rare in your area plus your appliances do not have a standing pilot light. If a home owner with standing pilot light units elects to protect with a Scentry, then we do recommend the battery back-up unit.

Remember to check your carbon monoxide alarms at least monthly and change batteries annually if they are 9 volt units. There is nothing worse than an alarm beeping a low battery warning at 3 a.m.

Thank you for your question and for being our customer. We show your unit arrived on time, Next Day Air Saver, as you requested.

Sincerely,

Barbara

120V Propane Alarms and CO Alarms Protect Park Model Trailers with Gas Appliances

by Barbara 12. April 2011 10:54

Question about the Safety Siren Propane and Natural Gas Alarm

Q: "We live in a park model modular home in a retirement community in northern Florida.  It is a one bedroom unit. Our furnace, our hot water heater and our range are all propane. A central tank supplies several homes. We've read that trailers and motor homes have 12 volt propane alarms and 12 volt carbon monoxide alarms hard-wired into the 12 volt system. Ours is 120Volt. The outlets are near the appliances and near the floor. The water heater is in a closet as is the furnace. What do we need to protect ourselves from a fire or explosion? Thanks. Tim and Diane."

Answer: In your situation, you need a minimum of two carbon monoxide alarms, one inside your bedroom and one in the living area at the other end. You need 3 propane gas alarms. Each one of your gas appliances needs a combustible gas alarm installed near to it. This means inside the closets where the furnace and the water heater reside. We understand from a park home model reseller that at least the newer models do have outlets near the appliances and near the floor.

Our suggestion is that you install two of the RV carbon monoxide units, the CoStar 9V Battery UL Home and RV Carbon Monoxide Alarm. This is because these units can handle both high humidity and high temperatures without sensors being destroyed. Operating Environment:-40 degrees F to +151 degrees F 15% to 95% RH. Since they are battery powered, you don't have to worry about plugging them into those very scarce outlets. Just change the battery out once a year.

As far as the propane alarms are concerned, we recommend that you use direct plug in units only if you have outlets close to the appliance and low to the floor. Propane is heavier than air so it sinks and pools around the bottom of an appliance. Otherwise, we recommend that you install the Safe-T-Alert Propane Natural Gas Alarm, 120V because it has a 65 inch cord that allows proper placement probably 99% of the time. This unit has micro current technology which means it uses only 3.8 watts of energy, which is about US $3.00 per year to operate. Since propane gas is heavier than air, mount this gas alarm within 4 to 20 inches of the floor. For methane or natural gas which is lighter than room air, mount the detector within 6 inches from the ceiling or on the ceiling at least 12 inches from a wall.

Thank you for your question. Remember that carbon monoxide is a by product of incomplete combustion of fossil fuels like propane, natural gas, wood, etc. Raw propane or natural gas detectors won't detect carbon monoxide nor will carbon monoxide sensors detect raw leaking gas. We do sell a combination plug in unit as well. Proper placement for carbon monoxide detector alarms is different from combustible gas alarms.  For example, gas-burning appliances may emit it a small amount of carbon monoxide when starting up. So this carbon monoxide alarm should be placed 15 feet or more from heating or cooking appliances and never hear a very humid room such as a bathroom.

Sincerely, Barbara

Safety Alarms Needed to Protect Home Recently Converted to Natural Gas Heat and Water Heater

by Barbara 31. December 2010 02:34

Question: "We recently converted to natural gas heat and gas hot water boiler. We have two floors above this basement installation. What safety alarm units are required for protection? Nate.

Answer: Thanks for your question for the Ask Barbara Contest, Nate. I am going to answer with the assumption that your home was all electric prior to this conversion. If you heated with propane or oil, some of these recommendations may not apply.

Natural gas homes or businesses need two different types of safety alarms.

Combustible Gas Alarms.

Why do I need a combustible gas detector/gas alarm?

The purpose of a combustible gas alarm is to alert you when you have a raw gas leak. Yes, mercaptan is added to natural gas to make it smell like rotten eggs. But if you are not in the area of the gas appliances and/or you do not have an ability to smell, the odor does you no good. This units must be installed near the gas using appliances. So if your gas furnace and gas water heater are side by side, one natural gas alarm is all you need.

  • No matter how good your nose is, you may not be in the right place at the right time to notice a natural gas or propane leak.
  • Carbon monoxide alarms give NO protection against combustible gas leaks. carbon monoxide sensors detect only carbon monoxide, not raw fuel.
  • Turning off a light, setting a security alarm or closing a door spark a gas explosion or fire. Natural gas leaking from a basement furnace can leak upstairs through hollow walls.
  • Gas can leak into homes via sump pits, inbound water lines or a natural gas well under your home.
  • Each gas appliance is a potential source of a gas leak. Each gas appliance needs its own gas detector
  • We sell two different models with gas specific sensors. These are the Safe-T-Alert Model 40-411-120 and the Safety Siren Pro Gas Alarm; The main differences between the units are how they are installed.

    To properly install the Safe-T-Alert you need an electrical outlet near to the gas appliances. Because this unit has a line cord that is approximately 65 long, mounting ths unit properly is usually less a problem that the direct plug-in Safety Siren. Raw gas detection units must be mounted within 6 inches of the ceiling or on the ceiling at least 12 inches from a wall for natural gas leak protection. Natural gas pools above the appliance: think of an upside down pothole filling with water and you get the picture.

    The Safety Siren requires an electrical outlet near the appliance. Many people choose this option because the Safety Alert unit has a safety tab through which an outlet screw goes. This means the unit cannot be removed from a standard, single screw, double outlet without removing the screw.  These units meet the UL1484 standards for combustible gas alarms.

    Note: UL 1484 listed combustible gas detectors are not detectors for minute gas leaks. Sensors and detectors are tested in a combustible gas environment and meet the UL 1484 standards for alerts of dangerous gas levels. Deliberate exposure to natural gas, butane, propane, etc. can destroy the sensor in this unit. Use the test button to test this unit, not exposure to raw gas.

    Carbon Monoxide Alarms:

    One product of natural gas and all fossil fuels like coal, wood, peat, etc. is carbon monoxide, a colorless, odorless gas. If your furnace and water heater are working properly, carbon monoxide is vented outside. If the vents are not working properly due to obstructions or the furnace heat exchanger cracks, then carbon monoxide is discharged into the air. Unlike combustible gasses, carbon monoxide does not pool but is distributed throughout your air. Carbon monoxide exposure symptoms range from flu-like symptoms to brain damage to death from asphyxiation.

    Recommended at a minimum are carbon monoxide alarms in or outside every bedroom, near the gas appliances and at the top of stairways. The easiest to install are the 9 volt battery units. Believe the alarm even if it sounds intermittently. About 5 years ago, I went to visit my parents in Pennsylvania. They have a washer and gas dryer in their kitchen (since 1952). I noticed that the Costar 9 volt CO alarms were all off their mounts (there were three units total). I was told they were "defective" as they were going off intermittently. I took them home with me and sent them to Quantum Group to be tested. Dave from Quantum phoned and said nothing was wrong with them! Meanwhile, my elderly father did NOT install the plug in Safe-T-Alert unit I had sent them because "I didn't know where to put it." The problem was the vent for the gas dryer was partially clogged with lint!  Since then, local code has changed: their 4 inch diameter gas dryer vent had to be replaced with a 5 inch for the newest dryer to be installed this past year.

    Types of Carbon Monoxide Alarms:

    If you are really concerned about a gas leak, we recommend the Scentry III gas valve shut off systems. Choose from a Scentry III GFRAB LP/Natural Gas Detector Valve Controller with remote sensor capability and a battery back-up option feature or a Scentry III SFGVC Automatic Gas Valve Controller, No Gas Valveunit with a single sensor at the gas valve itself. Scentry units are made in the USA. They do require a special diaphragm type gas valve in 1/2, 3/4 or 1 inch size, a 24 volt power supply and 120VAC or 240VAC power.

    Also install and maintain your smoke alarms which I am sure you already have.

    Thank you for your question and your entry in the Ask Barbara Contest.

    Sincerely, Barbara

    Install Safety First Automatic Gas Valve System and Prevent Gas Explosions In Home or Business

    by Barbara 20. September 2010 13:13

    Question about the Scentry III GFRAB Automatic Gas Valve and Gas Detector System and the Scentry III SFGVC Gas Valve Controller, No Gas Valve

    Q:"After the explosion in San Bruno, CA on 9/9/2010, I am concerned about my home exploding. I have a natural gas furnace, a natural gas fireplace, a natural gas water heater and a natural gas range. I don't have a full basement: my crawl space is about 12 inches high. Drainage is excellent. There would be some moisture but not water. Can this automatic gas valve and sensor system system be installed there?I see that the Scentry III has a connection for an auto-dialer and also can be connected to a ventilation system. Thanks. Thomas."

    Answer: This unit allows you to use remote gas detectors to place near your other gas appliances. There is a battery back-up available if you want protection during a power failure. We do have an installation manual available on our website for this unit.The Scentry Installation Manual.

    The GFRAB stands for gas sensor, mounting feet, remote ready, alarm and battery and includes the gas valve shut-off/controller. NOTE: Must be used with a Scentry III gas valve (sold separately).  Each Scentry gas sensor is calibrated in a gaseous atmosphere so it will alarm at 10% of the lower explosive level (LEL) of the combustible gas. This is not a carbon monoxide alarm as it has only a combustible gas alarm sensor.

    Scentry III-GFRAB Gas (Mounting) Feet Remote (Ready) Alarm Battery Specifications:

    • Case: ABS Plastic
    • Physical Size: 7.6 inches by 4.6 inches
    • Weight: 2.25 lbs
    • Color: Gray
    • Power consumption: 1.5va
    • Supports up to 4 calibrated remote sensors (not included)
    • Requires Scentry III-GVD gas valve (purchase separately)
    • Supports Battery Back-Up (Not Included)
    • Gas Valve Controller for combustible gasses such as natural gas or propane gas. Includes a 24 volt transformer.
    • Connections: screw terminals
    • Input Power: 115VAC, 60 Hz
    • Output Control Relays: 2 amps, 24 VAC
    • Alarm Signal Output: 12V DC @500 ma
    • Reset: manual
    • Sensor Type: Tin Dioxide Semiconductor
    • Alarm Points: Propane (LP) <5200 PPM
    • Alarm Points: Natural Gas / Methane <12,200 PPM
    • Manufactured Proudly in the USA for Safety First USA, Inc.
    • Warranty: 1 year from date of purchase.

    The gas valves that interface are a 1/2 inch, a 3/4 inch and a 1 inch valve.

    Scentry III-SFGVC Safety First Gas Valve Controller Specifications:
    • Case: ABS Plastic
    • Physical Size: 4.6 inches by 3.1 inches
    • Weight: .5 lb.
    • Color: Bone
    • Reset: manual
    • Output Control Relays: 4 amp, 24VAC
    • Power: 1.5va
    • Sensor Type: Tin Dioxide Semiconductor
    • Connections: screw terminals
    • Propane alarm point: <5200 PPM
    • Natural Gas/Methane<12,200 PPM
    • Note: Requires a UL Listed Scentry III .5 inch, .75 inch or 1 inch diaphragm type gas valve that is compatible (not included).
    • Note: Requires a 24V transformer (NOT INCLUDED). See installation instructions for specifications i.e. must match the transformer to power requirements of your gas valve.
    • Note: No option for battery back-up to be added later
    • Note: No option for additional sensors to be added later.
    • Made in USA.
    • Manufacturer: Safety First USA

    The gas valves that interface are a 1/2 inch, a 3/4 inch and a 1 inch valve.

    So the main differences between the units are that the Scentry III-GFRAB gas alarm and gas valve controller (shut-off) includes the 24 volt transformer, has mounting feet and can add options of battery back-up, remote gas sensors and remote alarms.  With the battery option, the pilot lights remain litt during intermittent power failures in regions such as the mountain states where electric power is not always continuous. A 12V output allows adding a phone dialer to alert owners of vacation homes, etc. when an unsafe condition has occurred. Remote gas sensors can be added near gas ranges, gas water heaters, gas furnaces, gas heaters, etc. to add protection using only one gas valve controller.

    Please contact us if you have questions about what components to install.

    Remember that you need carbon monoxide sensor alarms on every floor of your home and in every bedroom where you close the door. The CO monitor does not monitor propane or natural gas leaks: it monitors the carbon monoxide levels from incomplete combustion of fossil fuels like wood, coal, gas, charcoal, etc.

    Thanks again for your timely question.

    Sincerely, Barbara
