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. 8 for selector switch positions.
FIG. 8
A. H Heating
a. Open all manual fuel supply valves. Check for gas
leaks using an approved leak detector. The gas
control valve on the heater has a manual shut-off
feature incorporated into the valve assembly. Make
sure the indicator on the valve is turned to the on
position. See Fig 9.
FIG. 9
b. Position the selector switch to heat. 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. VVentilation
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, position the
switch to off or heat.
C. O Off
Position the switch to midpoint.
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 finally 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 flash a
specific continuous flash pattern depending on a
problem that occurs. Match specific flash pattern
given by L.E.D. to troubleshooting label applied to
inside of burner cap access panel of the heater. The
troubleshooting label identifies the causes of the
problem as it relates to specific flash pattern and
remedies to correct the problem. See also
“Troubleshooting Data” within this Owner’s Manual.
5. Do not exceed input rating stamped on nameplate or
manufacturer’s recommended burner orifice
pressure for size orifice(s) used. Make certain that
the primary air supply to main burner is open and
free of dust, dirt and debris for complete, proper
combustion.
