Follow steps 1 - 6 on initial start-up after heater installation
by a qualified service person. For normal start-up, simply set
the thermostat to a setting above room temperature.
1. Open all manual fuel supply valves and check for gas
leaks using approved leak detectors.
2. The gas control valve has a manual shut-off feature
incorporated into the valve assembly. Make sure the
indicator on the control valve is positioned to On.

3. This heater includes a direct spark ignition (DSI)
control module for purposes of controlling the timing
of the ignition process of the heater as well as
monitoring of the safety functions. The DSI module is
located in the control box assembly. Refer to the
troubleshooting guide within this Owner’s Manual.
Only qualified and properly-trained personnel shall
service or repair the heater.
4. On a call for heat, the motor will start up and run for
five (5) seconds prior to ignition trial. This pre-purge is
a safety feature and a normal operational
characteristic. After five (5) seconds the igniter will
spark until burner flame is detected by the control
module.
5. The ignition control will make three trials for ignition. If
ignition is not proven after the third trial, the control
will lock-out the heater. The ignition control must be
reset to restart the heater. Push the reset switch until
fan motor restarts, then release it. See Fig. 7.
NOTE:
It is normal for air to be trapped in the gas
hose on new installations.The heater may attempt
more than one trial for ignition before the air is finally
purged from the line and ignition takes place.
