WARNING

CAUTION

Check Safety Shutdown Performance

Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.

Perform the safety shutdown test any time work is
done on a gas system.

NOTE: Read steps 1 through 7 before starting, and

compare to the safety shutdown or safety
lockout tests recommended for the direct ignition
(DI) module. When different, use the procedures
recommended for the module.

1. Turn off the gas supply.

2. Set thermostat or controller above room tempera-

ture to call for heat.

3. Watch for ignition spark or glow at hot surface
igniter either immediately or following prepurge.
See DI module specifications.

4. Time the length of spark operation. See the DI
module specifications.

5. After the module locks out, open the manual gas
cock and make sure no gas is flowing to the main
burner.

6. Set the thermostat below room temperature and
wait one minute.

7. Operate system through one complete cycle to
make sure all controls operate properly.

MAINTENANCE

Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.

Do not disassemble the gas control; it contains no
replaceable components. Attempted disassembly,
repair, or cleaning can damage the control,
resulting in gas leakage.

Regular preventive maintenance is important in
applications in the commercial cooking and agricultural
and industrial industries that place a heavy load on
system controls, because:

• In many such applications, particularly commercial
cooking, the equipment operates 100,000 to 200,000
cycles per year. Such heavy cycling can wear out the
gas control in one to two years.

• Exposure to water, dirt, chemicals and heat can
damage the gas control and shut down the control
system.

The maintenance program should include regular
checkout of the control as outlined in the Startup and
Checkout section, and the control system as described in
the appliance manufacturer literature.

Maintenance frequency must be determined individually
for each application. Some considerations are:

• Cycling frequency. Appliances that cycle 20,000 times
annually should be checked monthly.

• Intermittent use. Appliances that are used seasonally
should be checked before shutdown and again before
the next use.

• Consequence of unexpected shutdown. Where the
cost of an unexpected shutdown would be high, the
system should be checked more often.

• Dusty, wet or corrosive environments. Since these
environments can cause the gas control to deteriorate
more rapidly, the system should be checked more
often.

The system should be replaced if:

• It does not perform properly on checkout or
troubleshooting.

• The gas control is likely to have operated for more than
200,000 cycles.

• The control is wet or looks as if it has been wet.

SERVICE

Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.

Do not disassemble the gas control; it contains no
replaceable components. Attempted disassembly,
repair, or cleaning can damage the control,
resulting in gas leakage.

Equipment Damage.
Can burn out valve coil terminals.

Never apply a jumper across (or short) the valve
coil terminals, even temporarily.

After servicing, verify proper system operation.

If Main Burner Does Not Come On With
Call For Heat

1. Confirm the gas control knob is in the ON position.

2. Adjust thermostat several degrees above room

temperature.

3. Using ac voltmeter, measure across MV terminals
at gas control.

4. If voltage is incorrect or not present, check control
circuit for proper operation.

5. If proper voltage is present, replace gas control.

WARNING

INSTRUCTIONS TO THE
HOMEOWNER

Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.

Follow these warnings exactly:

1. Before lighting, smell around the appliance for
gas. Be sure to smell next to floor because LP
gas is heavier than air. If you smell gas:

(a) Turn off the gas supply at the appliance

service valve. On LP gas systems, turn off
the gas supply at the gas tank.

(b) Do not light any appliance in the house.
(c) Do not touch electrical switches or use the

telephone.

(d) Leave the building and use a neighbor’s

phone to call your gas supplier.

(e) If you cannot reach your gas supplier, call

the fire department.

2. Replace the gas control in the event of any
physical damage, tampering, bent terminals,
missing or broken parts, stripped threads, or
evidence of exposure to heat.

IMPORTANT:

Follow the operating instructions provided by the
heating appliance manufacturer. The information
below describes a typical control application, but
the specific controls used and the procedures
outlined in your appliance manufacturer
instructions can differ, requiring special
instructions.

To Turn ON Appliance

STOP: Read the Warnings Above Before
Proceeding

1. The lighting sequence on this appliance is
automatic; do not attempt to manually light the main
burner.

2. If the furnace does not come on when the
thermostat is set several degrees above room
temperature, set the thermostat to its lowest setting
to reset the safety control.

3. Remove the burner access panel, if provided, on
your appliance.

4. Turn the gas control knob clockwise to OFF.

5. Wait five minutes to allow any gas in the

combustion chamber to vent. Then, if you smell
gas, STOP! Follow Step 1 in the Warning above. If
you do not smell gas, continue with the next step.

6. If you do not smell gas, turn the knob on the gas
control counterclockwise to ON.

7. Replace the burner access panel.

8. Reset the thermostat to the desired temperature.

9. If the appliance does not turn on, turn the gas

control knob to OFF and contact a qualified service
technician for assistance.

Turning Off the Appliance

Vacation Shutdown

Set the thermostat to the desired room temperature while
you are away.

Complete Shutdown

1. Turn off the power to the appliance.

2. Turn off the gas supply to the appliance.

3. Turn gas control knob clockwise to OFF.

Appliance will completely shut off.
