DJUSTMENT
NOTE: A QUALIFIED TECHNICIAN
MUST PERFORM THIS PROCEDURE!
The supply line pressure is tested to ensure
is meets minimum pressure requirements, as
listed in the Specifications sections of this
manual, for the type of fuel in use (NG or
LP).
The unit must be isolated from the gas
supply piping system by closing its
individual manual shutoff valve during any
pressure testing of the gas supply piping
system at test pressures equal to or less than
½ psig.
During tests in excess of ½ psig (14” w.c.),
the heater must be disconnected from the
gas supply system. Test by connecting a
manometer to the supply line. Adjust the
incoming pressure, if necessary, to meet the
required supply line pressure.
Once connected to the gas supply, the gas
inlet pressure and manifold gas pressure
must be tested. The gas inlet tap (6) and
manifold pressure tap (7) is located on the
control valve (see Figure 8). Connect a
manometer to the test points on the gas
control valve.
NOTE:
For installations from 610-1370
meters (2000-4500ft), the orifice sizes
(DMS) for natural and propane gas are 41
and 54 respectively. (
Cet appareil est
equipé pour des altitudes compries entre
2000 et 4500 pieds (610 et 1370m)
seulement.)
See data plate for additional
information. For high altitude installations
consult the local gas distributor or the
authority having jurisdiction for proper
rating methods. If the unit must be adjusted,
the information sticker (provided with the
high altitude kit) must be filled out
completely and mounted to the unit per the
instructions provided with the kit.

CAUTION:
Fragile!
Handle log set
with care. Always wear gloves and
safety goggles while handling the log
set.
Only the decorative ceramic fiber log set
supplied with the unit should be placed in
the firebox. Do not place any other ceramic
logs, wood logs, or other materials in the
firebox. If the log set is damaged or broken
contact your dealer for replacement. The
decorative ceramic fiber log set will last a
long time, however, they will break if
subjected to rough or improper handling.
Exact positioning of the log set is required in
order to obtain a pleasing flame pattern and
efficient combustion. Incorrect log
placement may cause carbon build-up;
excess thermal stress on the log set and
stove parts, reduced efficiency, and high
levels of carbon monoxide. If the log set
does not set into the firebox exactly as
outlined, contact your dealer for assistance.
