Venturi Adjustment; Flame Characteristics; Optional Anticondensation Switch (B35Nte And B35Pte Only) - Napoleon Ascent 35 Manuel D'installation Et D'opération

venturi adjustment

This appliance has an air shutter that has been factory set open according to
the chart below:
Regardless of venturi orientation, closing the air shutter will cause a more
yellow flame, but can lead to carbonization. Opening the air shutter will cause
a more blue flame, but 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 established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!
note:
It is important that the orifice is securely inserted into the venturi.

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.

optional anticondensation switch (B35NTE and B35PTE only)

This appliance has the option to change from an electronic intermittent pilot ignition (IPI) to a standing pilot for
colder climates. The anti condensation switch (ACS) (standing pilot) is located in the center of the control panel.
If installed with the blue wire facing up, flipping the switch UP turns on the standing pilot and flipping the switch
DOWN turns on the intermittent pilot ignition. If installed with the white wire facing up, the opposite is true.
Turning the ACS on will allow the pilot flame to burn continuously. This mode will minimize the condensation which
forms on the inside of the glass when the main burner is first turned on. It will also help the appliance and vent
system stabilize faster during colder winter months.
During the warmer winter and summer months, the ACS can be turned off to minimize fuel consumption.
