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.

The Boiler manual is for use only by a qualified
heating installer/service technician. Refer only to
this User’s Information Manual for your reference.
Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, personal injury (exposure to hazardous
materials) or loss of life. Installation and service
must be performed by a qualified installer, service
agency or the gas supplier (who must read and
follow the supplied instructions before installing,
servicing, or removing this boiler. This boiler
contains materials that have been identified as
