Inspect valve and ensure it is properly operating. Check piping
for leaks. Vacuum the control compartment, fireplace logs and
burner area.
Refer to Figure 13 on Page 9 and verify the flame pattern and
height displayed by the appliance conforms to the picture. Flames
must not impinge on the logs. Ensure flames are steady (not
lifting or floating).
Refer to Figures 15 & 16 on Page 10. Remove any surface
build-up on pilot and burner assembly. Wipe the pilot nozzles,
igniter/flame rod and hood. 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 dislocation or deterioration of the vent components. Note:
Excessive condensation can cause corrosion of caps, pipe &
fittings (excessive condensation can be caused by long lateral
runs, too many elbows and/or exterior portions of the system
being exposed to cold weather). Also inspect wall straps or
plumbers's tape to ensure it is secure and in place.
