NOVUS PLUS INSTALLATION INSTRUCTIONS
1. Annual Maintenance
To ensure that your appliance operates in a safe and efficient
manner, your appliance needs to be inspected at least on an
annual basis by a qualified field service person. Like any gas
appliance, it must be tuned up to ensure optimum
performance.
2. Clean 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. Always turn off the wall switch and the
gas valve before cleaning.
3. HRV200PLUS
Please refer to the HRV200PLUS manual for additional
maintenance requirements for the ventilation portion of the
Novus Plus.
4. Check the Flame Patterns
a.
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 should
be covered with flame from the pilot. See Figure 19.
•
Correct - Flames should be blue at the base, yellow-
orange at the top.
•
Not Enough Air - The flames are tall or sooty on the
ends. Open the air shutter.
•
Too Much Air - The flames are all blue, short and
transparent. Close the air shutter.
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.
Figure 19 - Intermittent Pilot Ignition Assembly
b.
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. If the vent
configuration is correct, yet the flames are lifting or
ghosting, shut off the gas to the appliance and contact
the dealer.

M. MAINTENANCE INSTRUCTIONS
c.
To reduce the possibility of soot, we have provided your
appliance with an adjustable air shutter. Your air shutter
is provided at 1/8 in. open for natural gas appliances, at
3/8 in. open for propane (30 in./33 in.) appliances, and
fully open for 36 in. and 42 in. propane appliances. 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 two
wing studs and two wing nuts attaching the valve
assembly to the firebox. Remove the wing nuts and wing
studs, slide the valve assembly to the left and lower.
Rotate the valve assembly horizontally and remove from
underneath the appliance. See Figure 20.
Note:
the valve assembly pilot side first, as shown in
Figure 20.
Figure 20 - Removing the Valve Assembly
d.
Locate the air shutter mounted on the end of the main
burner. Loosen the locking screw, open the air shutter,
and tighten the locking screw. See Figure 21.
e.
Replace the valve assembly, wing nuts and wing studs
as removed, making sure to line the orifice up with the
main burner neck.
