CALIBER DESIGNER DIRECT VENT
Note:
If the air shutter is open all the way and the
flames remain sooty, shut off gas to the appliance
and contact a qualified gas service technician.
To prevent the possibility of soot buildup, we have
provided your appliance with an adjustable air shutter.
Your air shutter is provided in the CLOSED position
for natural gas and in the OPEN position for propane.
It takes sixteen full turns (360°) to move the air shutter
from fully open to fully closed. In the event soot is
accumulating in your appliance, the air shutter should
be opened further. This can be done by opening the
control access panel and locating the fixed wing bolt
located on the bottom of the appliance. When the wing
bolt is turned down, the air shutter is fully closed. When
the wing bolt is turned up, the air shutter is fully open.
Note:
The look of the flames and embers may dif-
fer based on the type of fuel and venting assembly
that is used.

N. MAINTENANCE INSTRUCTIONS
1. Cleaning the Burner and Control Compartment
Keep the burner and control compartment clean by
brushing and vacuuming at least once a year. Always
turn off the wall switch (or remote control) and gas valve
before cleaning.
2. Checking the Venting system
The appliance and venting system should be inspected
before use, and at least annually, by a qualified field
service person, to ensure that the flow of combustion and
ventilation air is not obstructed.
3. Checking Flame Patterns
Check the flame pattern of the burner periodically, making
sure the flames are steady, not lifting or floating. See
Figure 57. The flame color should be blue with yellow
tips.
The thermopile and thermocouple tips (standing pilot)
should be covered with flame. See Figure 58. The flame
sensor (intermittent pilot) should be covered with flame.
See Figure 59.
If the vent configuration is installed incorrectly, the vent
may cause the flames inside the appliance to lift or ghost
- a dangerous situation. Inspect the flames after
installation to ensure proper performance. See Figure 57.
If the vent configuration is correct, yet the flames are lifting
or ghosting, shut off gas to the appliance and contact the
dealer.

Note:
After extended periods of burning, film may
build up on the flame sensor (intermittent pilot
ignition). The flame sensor should be cleaned
annually with emery cloth to remove this build up.
