AFTER SERVICING: VISUAL INSPECTION OF FLAME
Verify proper operaon aer servicing. The burner must ame evenly over the enre surface when
operang correctly. The ame must burn with a clear, blue, stable ame. See the parts breakdown
of the burner for the locaon of the view ports. The ame paern should be as shown in the

Inspecon:
• To maintain opmum performance, periodically inspect the air lter.
• If the air lter appears to have lint and/or dust build up, follow the cleaning
procedure described below.
• If the air lter appears damaged, contact a trained and qualied professional for a
replacement air lter assembly.
Cleaning:
• Clean the Air Filter: With mild dish soap and a so bristle brush, scrub the lter area
of the air lter door. With clean water, rinse the soap o the lter.
• Dry the Air Filter: With a lint free towel, dry the air lter.

Freeze Protecon Operaon
When the boiler detects low outdoor ambient
temperatures, the boiler will begin its freeze
protecon operaon. The freeze protecon
operaon can protect the boiler from freezing
down to as low as –22°F (-30°C) outdoor
temperature.
When freeze protecon is in operaon, the
pump may circulate water and/or the boiler may
operate to prevent the boiler from freezing.
Ensure power and gas are supplied to the boiler
for freeze protecon to funcon. The internal
freeze protecon will not necessarily prevent
the system piping from freezing.
During freeze protecon operaon, the pressure
and supply temperature will alternately display
on the controller.
The icon for CH and DHW may alternate
depending on the operaon of the freeze
protecon sequence.
When the system needs to be shutdown for
extended periods of me, the boiler and all
system piping should be drained. The power
and gas supply should then be disconnected
from the boiler. Freezing damage may occur if
there is water remaining in the boiler or system
piping. The plumbing lines should also be
blown out via compressed air.
