NOVUS DIRECT VENT INSTALLATION INSTRUCTIONS
d.
Locate the air shutter mounted on the end of the
main burner. Loosen the locking screw, open the
air shutter, and retighten the locking screw.
e.
Replace the valve assembly, wing nuts and wing
studs as removed, making sure to line the orifice
up with the main burner neck.
Note:
To avoid damage to the pilot assembly,
remove the valve assembly pilot side first. If
the valve assembly gasket is damaged, it
should be replaced. See Figure 61.
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.
c.
To reduce the possibility of soot, we have provided
your appliance with an adjustable air shutter. See
Figure 60. Your air shutter is provided at 1/8 in.
open for natural gas, 3/8 in. open for propane
(30 in./33 in./36 in. appliances), and full open for
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 61.
4. Inspect 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.
WARNING!
NEVER operate this appliance without the glass prop-
erly secured in place or if the glass is broken or
chipped.
5. Cleaning the Glass
(See Figure 62)
In the event of glass breakage, carefully remove the
glass frame. This will allow the removal of all glass
fragments and sheet metal edge protection strips.
Vacuum all remaining glass pieces with a shop vac.
DO NOT VACUUM IF THE PIECES ARE HOT!
Replace glass with only a Heatilator Glass Panel
Assembly ordered through your local distributor. Never
use substitute material. Only fully tempered soda lime
safety glass or ceramic glass may be used on this
appliance.
