NOVUS B-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. Failure to
do this may shorten the fan’s life (where applicable).
Always turn off the wall switch (or remote control) and
gas valve before cleaning.
2. CHECKING FLAME PATTERNS
Visually 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. The
sensor (intermittent pilot) or thermopile and
thermocouple (standing pilot) tips should be covered
with flame. See Figures 26 and 27.
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 28. If the vent configuration is correct, yet
the flames are lifting or ghosting, shut off gas to the
appliance and contact the dealer you purchased the
appliance from.
Note: The look of the flames and embers may differ based
on the type of fuel and venting assembly that is required.
