WARNING: When purging gas piping, the area around the floor
furnace must be well ventilated to allow any gas to dissipate. Liquid
Petroleum (Propane) Gas is heavier than air and may puddle in
low places under the floor. Check thoroughly to determine that no
gas is present before lighting the floor furnace. Failure to do so
could result in property damage, bodily injury or death.
