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 the thermopile must be 3/8" to 1/2" above the pilot
flame as shown in Figure 27. The thermocouple must be at a height
of about 1/8" above the pilot flame. The flame from the pilot burner
must extend beyond both the thermocouple and thermopile.
If your pilot assembly does not meet these requirements:
• turn appliance off (see
To Turn Off Gas to Appliance, page 16)
• see
Troubleshooting, page 20
