Check pilot flame pattern and burner flame
patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the
proper flame height. Alterations may have
occurred during shipping and handling. Call
a qualified service person to readjust the pilot
if necessary.
The height of thermopile must be 3/8" to 1/2"
above pilot flame as shown in Figure 49. The
thermocouple must be at a height of about
1/8" above pilot flame. Flame from pilot burner
must extend beyond both thermocouple and
thermopile.
If you pilot assembly does not meet these
requirements:
• turn fireplace off (see
To Turn Off Gas to
Appliance
, page 28)
