use at elevations of 0 to 2,000 feet (610 M) in the
USA and 0 to 4,500 feet (0-1372 M) in Canada. At
higher elevations the BTU input must be de-rated
by 4% for every 1,000 feet (305 M) to maintain
the proper ratio of gas to air. If the installer must
convert the unit to adjust for varying altitudes, a
deration information sticker must be filled out by the
installer and adhered to the appliance at the time
of the conversion. Contact your local gas supplier
for deration requirements for your area.

INSTALLER NOTICE: THESE INSTRUCTIONS MUST BE LEFT WITH
THE APPLIANCE.
This kit contains components required to convert this appliance
from using Natural Gas to using Propane Gas as the only fuel.
All of these components must be replaced in order for the unit to
operate safely on Propane Gas.
When installing gas components use pipe joint compound or
Teflon tape on all pipe fittings before installing (ensure propane
resistant compounds are used, do not use pipe joint compounds
on flare fittings).
INSTALLATION INSTRUCTIONS
Step 1. TURN OFF THE GAS SUPPLY TO THE APPLIANCE. Unplug the
power cord for the blower.
Step 2. Locate the valve behind the right side access door. Using a phil-

the new regulator. Ensure the rubber gasket on the back of the
pressure regulator is properly positioned when installing the new
pressure regulator using the new screws supplied with this kit.
