Inspect valve and ensure it is properly operat-
ing. Check piping for leaks. Vacuum the con-
trol compartment, fireplace logs and burner
area.
Refer to Figure 6 on page 7 and verify that the
flame pattern and height displayed by the
appliance conforms to the picture. Flames
must not impinge on the log set.
Refer to Figure 9 on page 7 (millivolt) or Figure
10 on page 8 (electronic). Remove any surface
build-up on pilot and burner assembly. Clean the
pilot nozzles, ignitor/flame rod and hood with a
soft brush. Ensure the pilot flame engulfs the
flame sensor as shown.
Inspect the vent system at the top and at the
base (within the firebox) for signs of blockage
or obstruction. Look for any signs of disloca-
tion of the vent components.
Perform the appropriate appliance checkout
procedure detailed in this manual.
Maintenance Schedule
Annually (Before the onset of the Burning Season)
Clean as necessary following the directions
provided in this manual. DO NOT TOUCH OR
CLEAN GLASS WHILE IT IS HOT.
Inspect the vent system at the top and at the
base (within the firebox) for signs of block-
age or obstruction. Look for any signs of
dislocation of the vent components.
Refer to Figure 6 on page 7 and verify that
the flame pattern and height displayed by the
appliance conforms to the picture. Flames
must not impinge on the log set.
These are direct-vent appliances. They are de-
signed to operate only with the glass enclosure
panels properly installed. Generally the glass
enclosure panels should not be removed ex-
cept to gain access to the components within
the firebox, and the appliance may only be
operated without the front glass enclosure panel
in place for very brief periods of time during
initial appliance checkout and adjustment. During this appliance checkout and adjust-
ment period, a potential safety hazard exists
- EXERCISE EXTREME CAUTION to prevent
the occurrence of any burn injuries from the
exposed flames or hot surfaces. Also note, that while the front glass enclosure
panel (or any of the panels) is removed, the
flame appearance will appear to be smaller
than normal.
