Start-Up Instructions

For initial start-up after heater installation, follow
steps 1-5. For normal start-up, set the thermostat
above room temperature.
1. Connect electrical cord to an approved electrical
outlet.
2. Set thermostat to desired room temperature.
3. A selector switch is located on the back of the
heater. This switch allows you to either heat or
ventilate (no heat). See Fig. 10 for selector switch
positions.

A. Heating Mode Operation
a. Open all manual fuel supply valves. Check for
gas leaks using an approved leak detector.
Regardless of model purchased , the gas control
valve in the heater has a manual shut-off feature
incorporated into the valve assembly. Ensure the
indicator is turned to the on position. See Fig 11,
Premier 35DF valve shown.

b. Position the selector switch to heat.
See Fig. 10. A red light within the switch will come
on. The fan motor will start, the igniter will spark
and ignition will occur. The thermostat will cycle
the heater on or off based upon temperature
setting.
B. Ventilation Mode Operation
When the selector switch is positioned to vent,
the red light will NOT be on. The fan motor will start,
but the igniter will not spark, nor will ignition occur.
This feature is used only when air circulation is
required. The heater will not cycle on its thermostat
setting. To discontinue the ventilation feature, posi-
tion the switch to off or heat.
C. Off O
Position the switch to midpoint. O
ATTENTION
■ It is normal for air to be trapped in gas hose on
new installations. The heater may attempt more
than one trial for ignition before air is fi nally
purged from line and ignition takes place.
4. The direct spark ignition (DSI) control board
within this heater is self-diagnostic. The board
works in conjunction with a light emitting diode
(L.E.D.) built into the selector switch. The L.E.D.
will fl ash a specifi c continuous fl ash pattern de-
pending on a problem that occurs. Match specifi c
fl ash pattern given by L.E.D. to troubleshooting
label applied to inside of burner cap access panel
of the heater. The troubleshooting label identi-
fi es the causes of the problem as it relates to
specifi c fl ash pattern and remedies to correct the
problem. See also "Troubleshooting Data" within
this Owner's Manual.
