Propane Furnace Safety

The inspection tag on a propane tank should include an inspection date.

There are many available home-heating methods, from wood-burning fireplaces to electric heaters. Another option is gas heating, and a common option is a propane furnace. A propane furnace can be economical, but it always carries the potential of explosion due to gas leaks or malfunctions. By taking proper safety measures, propane-related hazards can be avoided.

Warning Signs

There are some warning signs that tell you that preventative action may be too late. National Furnace Heating and Air Conditioning lists six issues that could signal that your propane furnace is malfunctioning: presence of rust in and around the furnace; when operating, the furnace produces metallic sounds; the presence of carbon monoxide (via a carbon monoxide detector); a yellow flame (it should be blue); when operating, the furnace emits dust particles; and backdraft (air comes into the house from the chimney). For each warning sign, a technician should be called.

Inspection

The entire furnace--vents, ducts and the furnace body--should be inspected annually by a professional who is either affiliated with the company from which the furnace was bought, or is experienced with the particular brand. If the inspection comes before the cold season, inspect the vents again for insects before the furnace is started.

Maintenance

Some furnaces require lubrication. Refer to the furnace manual or contact the dealer for specific lubrication details. National Furnace Heating advises that the registers should not be closed more than 20 percent, as the resistance could cause backdraft, and to regularly clean the furnace burners. The burners should be cleaned when the furnace is cool.

Cleanliness and Proximity

The outside of the furnace and the floor surrounding it should be dusted and swept often. Nothing that is combustible, or any type of chemicals or caustic liquids, should be kept near the furnace. A separate room is preferable.

Cylinder Safety

Propane cylinders should not be stored inside the home, but outside, in a vented location. Older cylinders should be checked before each refill and first-time use for leaks, cracks and dents. A tag located on the tank should carry an inspection date.
