5.8 Connecting the cooling tube to the fl ame inspection window
The flame inspection window is equipped with a pressure fitting (1).
Once the interior screw is loosened, it must be connected to outlet 2 on
the burner using a silicone hose or copper pipe. This allows the air
blown back by the fan to cool the glass on the window and prevent it
from turning black. Failure to connect the hose or pipe to the window
can cause the glass to break.
When disassembling the window for cleaning, check the condition of
the seals, replacing them if necessary. After closing, verify tightness.
