WHAT TO DO IF YOU SMELL GAS
GWA
GWI
Gas-Fired Water Boilers
Propane gas odorant
Propane boilers only — Your propane supplier
mixes an odorant with the propane to make its pres-
ence detectable. In some instances, the odorant can
fade and the gas may no longer have an odor.
•
Propane gas can accumulate at floor level. Smell near the
floor for the gas odorant or any unusual odor. If you suspect
a leak, do not attempt to light the pilot.
•
Use caution when attempting to light the propane pilot. This
should be done by a qualified service technician, particularly
if pilot outages are common.
•
Periodically check the odorant level of your gas.
•
Inspect boiler and system at least yearly to make sure all gas
piping is leak-tight.
•
Consult your propane supplier regarding installation of a gas
leak detector. There are some products on the market intended
for this purpose. Your supplier may be able to suggest an
appropriate device.
