Initial Lighting Instructions
1. Open the manual shut-off valve. The valve is fully open when the
handle is level or parallel to the gas line. Never attempt to operate unit
with manual valve partially closed.
2. Depress “System” key pad until heat lamp
is illuminated. (See
Figure 31
.)
3. Depress “Fan” key pad until desired speed
lamp is illuminated. (See
Figure 31
.)
4. Set thermostat to desired setting by
depressing temperature-indicating arrows
until desired temperature is displayed.
5. If the thermostat circuit is closed at the
setting chosen in Step #4, the ignition
sequence begins. After approximately
20-25 seconds, the main burner should
be established.
6. After ignition, the operation of the
unit will be controlled automatically by
the thermostat.
To Shut Down for an Extended Period of Time
1. Depress “System” key pad until standby lamp is illuminated.
2. Close manual shutoff valve.
Sequence of Normal Operation – Heat Mode
1. When heat is required, the thermostat closes and energizes the combustion
air motor and the supply air motor.
2. As the blower reaches approximately 90% of the normal RPM, the
pressure created by the combustion air motor causes the diaphragm in
the pressure switch to move, closing the contacts. This completes the
electrical circuit to the input of the module board and a 10-second
warm-up period for the glo-bar is established. During the warm-up period,
the glo-bar comes on for 10 seconds, then the valve opens. The glo-bar
remains on another 3 seconds after the valve opens and then goes off.
When the valve opens, it will remain open for 6 seconds. Gas will flow
to the burner and be ignited by the glo-bar.
3. If the main burner flame is sensed, the burner will remain on until
the thermostat is satisfied. If the flame is not sensed, the gas valve closes
and the ignition sequence is automatically repeated two (2) times. If the
burner does not light during this trial for ignition period, the unit will
lock out for one (1) hour and then re-set automatically.
NOTE:
If lock-out should occur, the unit can be re-set manually by selecting
Standby and then selecting Heat Mode. The ignition procedures can now
be repeated. Should repeated lock-out occur, shut unit down and contact
service agency.
4. When the thermostat is satisfied, the valve closes. The combustion
air motor will remain on for a 30-second purge cycle, then goes off. The
room air blower will continue to operate for approximately 90 seconds at
which time the circuit is opened and the room air blower goes off.
