NOVUS REAR DIRECT VENT
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. Failure
to do so may shorten the fans life (where applicable).
Always turn off the wall switch (or remote control) and
gas valve before cleaning.
2. CHECKING THE VENT SYSTEM
Test the venting system periodically to assure proper
operation.
3. CHECKING FLAME PATTERNS
Check 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. See Figure
38. The ignitor (electronic) or thermopile and
thermocouple (standing pilot) tips should be covered
with flame. See Figures 40-42.
If the vent configuration is installed incorrectly, the vent
may cause the flames inside the appliance to lift or
ghost, which is a dangerous situation. Inspect the
flames after installation to ensure proper
performance. See Figure 43. If the vent configuration
is correct, yet the flames are lifting or ghosting, shut
off gas to the appliance and contact the dealer.
Note:
The look of the flames and embers may dif-
fer based on the type of fuel and venting assembly
that is required.
