Sequence of operation:
1. Turn On/Off switch ( or thermostat) to the
on (call for heat) position.
2
Main burner lights.
3. If blower variable speed switch is in the
“On” position then the blower will turn on
automatically once the unit is hot enough.
4. Once the On/Off switch is turned off ( or
thermostat is satisfied) then the flame will
extinguish.
5. Blower will keep on running until the fire
place has cooled down.
Shut Down Instructions:
1. Turn On/Off switch ( or thermostat) to the
off position.
2. Depress gas valve and turn to “OFF”
position.
11. CHECK-OUT
Once installed, the unit should be operated at least
three (3) times to ensure that all is in working order.
NOTE: MANUFACTURING OILS AND PAINT WILL
SMOKE DURING INITIAL FIRING OF APPLIANCE.
OPEN WINDOWS FOR VENTILATION.
12. UNIT ADJUSTMENT
BEFORE LEAVING, THE INSTALLER SHOULD
MAKE THE FOLLOWING CHECKS
:
(a) BTU/INPUT / GAS PRESSURE
The fireplace input is marked on the Rating Plate. The
gas valve comes factory pre-set to the proper rated
pressure and adjustment should not be necessary . If
there is any question of input then it may be necessary
to check manifold pressure.
Manifold pressure on the S.I.T. Nova valve can be
measured by loosening the slotted pressure taps on
the front bottom left of the valve. (‘E’ Inlet Pressure, and
‘A’ Manifold Pressure) and connecting a manometer.
(b) MAIN BURNER / PILOT
The
pilot flame
size is factory set. The pilot flame
should be at least 1.5 inches ( 4 cm) long. The flame
should be impinging on the pilot generator . Pilot size
can be adjusted through the pilot adjust screw. If the
pilot flame is too small and can not be adjusted through
the pilot adjust screw then there is the possibility of dirt
in the pilot orifice in which case the pilot orifice should
be cleaned or replaced.
Pressure ranges are as listed below:
Gas Supply Pressure (inches w.c.)
Min Normal
Max
Natural Gas 4.5
7.0
9.0
L.P. (propane) 10.8
11.0
12.0
Manifold Pressure (inches w .c. )
Normal(HI)
(LOW)
Natural Gas
3.5
1.6
L.P. (Propane)
10.0
6.3
The unit as shipped is equipped for operation for 0 to
4500 ft.
The
main burner
should be allowed to operate for 15 to
20 minutes before making any adjustment to the unit.
The
air shutter
should never be closed all the way. For
Natural Gas and Liquid Propane
it is recommended
that the air shutter be set to Factory Specifications.
(See Page 4) .
If there is
too much primary air
then the flame will be
very blue with yellow tips and smaller flame height.
If there is
too little primary air
then the flame will be
yellow with orange/red tips on the back flames with dark
sooty elongated tips. In this condition the glass and logs
could show signs of soot accumulation within 10 to 20
minutes.
NOTE:
With a properly burning flame there
will still be a certain level of sooting. It may be
necessary to clean the glass up to 3 times
during a cold season. The amount of cleaning
required depends on the amount that the fire
place is used.
