AFTER SERVICING: VISUAL INSPECTION OF FLAME
Verify proper operation after servicing. The burner must flame evenly over the entire surface when
operating correctly. The flame must burn with a clear, blue, stable flame. See the parts breakdown
of the burner for the location of the view ports. The flame pattern should be as shown in the

Freeze Protection Operation
When the boiler detects low outdoor ambient
temperatures, the boiler will begin its freeze
protection operation. The freeze protection
operation can protect the boiler from freezing
down to as low as –22°F (-30°C) outdoor
temperature.
When freeze protection is in operation, 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 protection to function. The internal
freeze protection will not necessarily prevent
the system piping from freezing.
During freeze protection operation, the pressure
and supply temperature will alternately display
on the controller.
The icon for CH and DHW may alternate
depending on the operation of the freeze
protection sequence.

When the system needs to be shutdown for
extended periods of time, 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.
