To inspect base insulation:
The boiler contains ceramic fiber and fiberglass materials.
Use care when handling these materials. See WARNING
above. Failure to comply could result in severe personal
injury.
Make sure base insulation is secure against base front and back panels. If
base insulation is damaged or displaced, do not operate boiler. Replace
or reposition insulation.
Failure to replace damaged insulation or reposition
insulation can result in a fire hazard, causing severe
personal injury, death or substantial property damage.

To place in operation:

1. Make sure boiler is filled with water.
. Follow lighting/operating instructions on boiler.
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 a 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.
