CALIBER DIRECT VENT INSTALLATION INSTRUCTIONS
M. 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 Vent System
The venting system should be checked for
obstructions to assure proper operation.
3. Checking Flame Patterns
Check the appearance of the flame of the burner
periodically, making sure the flames are steady, not
lifting or floating. The flame color should be blue with
yellow tips. The flame sensor (intermittent pilot) or
thermopile and thermocouple tips (standing pilot)
should be covered with flame. See Figures 65 and 66.
Note:
The look of the flames and embers may dif-
fer based on the type of fuel and venting assembly
that is required.

To prevent the possibility of soot, 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 16 full turns
(360 degrees) 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 farther. This
can be done by opening the control access panel and
locating the fixed wing bolt (Figure 68) located on the
bottom of the appliance. When the fixed wing bolt is turned
all of the way
DOWN
, the air shutter is fully
closed
. When
the fixed wing bolt is turned all the way
UP
, the air shutter is
fully
open
.

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 67. 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.
