flame characteristics

It's important to periodically perform a visual check of
the pilot and burner flames. Compare them to the
illustration provided. If any flames appear abnormal,
call a service person.

flame height adjustment

The adjustment is made by turning the Hi/Lo knob. The "Hi" setting corresponds to the maximum pressure to the
burner and "Lo" corresponds to the minimum pressure. Actuation of this knob is independent from the actuation
of the ON/OFF control.
The air shutter settings are factory set for most installations. However,
adjustment may be required depending on fuel type, vent performance
P
and altitude.
Closing the air shutter will cause a more yellow flame, but can lead to
7/16"
carboning. Opening the air shutter will cause a more blue flame, but
7/16"
can cause flame lifting from the burner ports. The flame may not appear
yellow immediately; allow 15 to 30 minutes for the final flame colour to be
7/16"
established.
