Propane Gas Odorant

WARNING
!
Propane boilers only — Your propane supplier
mixes an odorant with the propane to make its
presence 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
