Start-Up Instructions
Follow steps 1-5 on initial start up after heater
installation by a qualified gas heater service per-
son. For normal startup, simply turn the building
thermostat above room temperature.
1. Connect the heater to an approved electrical
supply and building's temperature control
system.
2. Open all gas supply valves to the heater and
check for gas leaks at all connections using
approved leak detectors.
3. Energize the building's temperature control
system to provide power to the heater.
4. Position the ON/OFF switch on the heater's
control box to I (ON.) See Fig. 9. The igniter
will spark and ignition will occur.
5. Set the building's temperature control to
desired temperature.
■ It is normal for air to be trapped in the gas line
on new installations.
■ The heater may attempt more than one ignition
trial before air is purged from the line and
ignition occurs.
This heater includes a spark ignition control
module for purposes of controlling the timing of
the ignition process of the heater as well as moni-
toring the safety functions. The control module
is located in a control box at the gas inlet end
of the heater. On a call for heat, the igniter will
spark and the gas control valve will open shortly
afterward. The igniter will continue to spark for
approximately 10 seconds. Flame sense, as
monitored by the ignition control, will keep the
gas valve open and main burner in operation until
proper temperature is achieved.
The ignition control module will make up to 3
trials for ignition. There will be a 15 second time
span between each ignition trial. If ignition is not
achieved after the third trial, a 15 minute wait
period will occur. After the 15 minute time span
has passed, the heater will make three more
trials for ignition. This process will continue as
long as there is a call for heat from the building's
temperature control system.

Shut-Down Instructions
The building's environmental temperature control
system will shut the heater down after proper
temperature has been achieved.
If heater is to be shut down for cleaning,
maintenance or service:
1. Shut off all gas supply valves to the heaters.
2. Allow heaters to burn off fuel gas remaining in the
gas supply line.
3. Position the ON/OFF switch to O (OFF).
4. Disconnect the heater from its electrical supply.
