Installing the Trim
Combustible materials may be brought up to the
specifi ed clearances on the side and top front edges
of the heater, but MUST NEVER overlap onto the front
face. The joints between the fi nished wall and the
heater top and sides can only be sealed with a 149°
C minimum sealant.
WARNING: WHEN FINISHING THE HEAT-
!
ER, NEVER OBSTRUCT OR MODIFY THE
AIR INLET/OUTLET GRILLES IN ANY
MANNER.
Install optional marble and brass trim surround kits
as desired. Marble, brass, brick, tile, or other non-
combustible materials can be used to cover up the gap
between the sheet rock and the heater.
Do not obstruct or modify the air inlet/outlet grilles.
When overlapping on both sides, leave enough space
so that the bottom grille can be opened and the trim
door removed.
1.7 INSTALLER TESTING
The space heater must be tested and be operating
according to manufacturer's specifi cations prior to the
installer leaving the site. Note: the tips of the fl ames
should never hit the top of the fi rebox after the unit has
warmed up. Please contact your dealer or a qualifi ed
service person to replace injector or adjust valve.
Upon completing the gas line connection, a small
amount of air will be in the lines. When fi rst lighting
the pilot light, it will take a few minutes for the lines
to purge themselves of this air. Once the purging is
complete, the pilot and burner will light and operate as
indicated in the Lighting Instructions.
Subsequent lightings of the appliance will not require
such purging.

Follow the Safety Information and Lighting Instructions
pages of this manual to light the appliance.
To obtain proper operation, it is imperative that the
pilot and main burner fl ame characteristics are steady,
not lifting or fl oating. Typically, the top 10 mm of the
thermocouple should be engulfed in the pilot fl ame
(see Figure 45).
Proper gas log positioning is shown in Section 1.8.
Follow Section 3.5 TROUBLESHOOTING for adjusting
the appliance to operate properly.
