INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper ame. Altera-
tions may have occurred during shipping and handling. The pilot
is located on the back right hand side of the burner.
The ame must envelope 1/4" of top of the ignitor/sensor and
grounding stem.
If your pilot assembly does not meet these requirements:
• Turn the adjustment screw marked PILOT clockwise to decrease
or counterclockwise to increase the ame to proper size (see
Figure 48, page 23). Do not remove the adjustment screw.
• see Troubleshooting, page 26
BURNER FLAME PATTERN
Burner ames will be steady; not lifting or oating. Flame patterns
will be different from unit to unit and will vary depending on instal-
lation type and weather conditions.
If the vent conguration is installed incorrectly, the ames will lift
or "ghost". This can be dangerous. Inspect the ames after instal-
lation to ensure proper installation and performance.
Figure 51 shows a typical ame pattern.
If burner ame pattern differs from that described:
• turn replace off (see To Turn Off Gas to Appliance, page 23)
• see Troubleshooting, page 26

Sensing Rod
Locate the blower controls by opening the lower louver panel
on the replace. Blower controls are located on the left side of
the switch bracket to the left just inside the louver panel.
The BK manual blower and the BKT thermostatically-controlled
blower have an ON setting and an OFF setting. The blower
will only run when the switch is in the ON position. In the OFF
position, the blower will not operate.
Note for BKT Only: If you are using BKT blower with optional
thermostat (wall mounted or remote control) for the replace,
your replace and blower will not turn on and off at the same
time. The replace may run for several minutes before the blower
turns on. After the heater modulates to the pilot position, the
blower will continue to run. The blower will shut off after the
rebox temperature decreases.
The blower helps distribute heated air from the replace. Peri-
odically check the louvers of the rebox and remove any dust,
dirt, or other obstructions that will hinder the ow of air.
