WARNING
Fire and Explosion Hazard
■
Do not disassemble the gas control valve.
■
Do not attempt to replace any components on the gas
control valve.
■
The gas control valve must be placed if any physical
damage occurs to the control valve assembly.
■
Failure to follow this warning will result in fire or
explosions, leading to injury or death to humans and
livestock, and building damage.

1. Brush off any accumulation of dust that may be
found.
2. Check manifold gas pressure with a low pressure gas
gauge:
a. Shut off the gas supply to the heater.
b. Disconnect the heater from its electrical supply.
c. Remove the metal cover from the control valve
enclosure.
d. Turn the screw in the pressure tap at the outlet of the
valve counterclockwise a minimum of one full turn.
e. Connect a low pressure gas gauge to the pressure
tap.
f. Open fuel supply and reconnect heater to electric
supply.
g. When heater lights, the gas gauge will read 2.50
KPa - LP or 1.13 KPa - Natural gas pressure. This
pressure is the flowing gas pressure necessary for
the heater to deliver maximum output. If the
gauge does not indicate proper manifold pressure,
check inlet pressure to the gas control valve.
Maximum and minimum acceptable inlet
pressures to gas control valve are shown in the
heater specifications table (See page 4.) and on
the heater’s dataplate The inlet pressure may
need adjustment as necessary to achieve proper
manifold pressure. Inlet pressure is checked in
the same manner as outlet pressure.
h. After pressures have been checked, shut off the
gas supply and electrical supply to the heater,
remove the gauge, and tighten the pressure tap
securely. Open gas supply and reconnect the
heater to its electrical supply.
3. Reinstall the metal cover.

IGNITER
1. Shut off the gas supply to the heater.
2. Disconnect the heater from its electrical supply.
3. Open the burner end access panel.
4. Disconnect the plastic male and female plugs located
at the end of the igniter leads. See Fig. 12
5. Remove the screw securing the igniter shield and the
igniter to the mounting bracket and remove the igniter
and shield.
6. Connect the male plug on the replacement igniter to
the female connector plug on the red wires which
lead back to 9 pin connector housing.
7. Position the igniter so the lip on back side of igniter is
resting on the edge of the mounting bracket and so
the mounting hole in the igniter aligns with the
mounting hole in the bracket.
8. Slide the igniter shield over the igniter so hole in
shield aligns with hole in igniter and bracket.
1. Shut off the gas supply to the heater.
2. Disconnect the heater from its electrical supply.
3. Open the motor access panel.
4. Turning counterclockwise, disconnect the 9 pin
female/male pin connector socket located on the
back of the panel.
5. Remove three (3) screws on each side of the control
panel and remove the control box from the heater.
6. To assemble, reverse above procedure.
