PROPANE (LP) GAS INSTALLATIONS ONLY
For units operating on propane gas, please review the following
warnings before use.
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO
EXPLOSION OR FIRE, INSTALL A GAS DETECTING WARNING DEVICE. SINCE THE
ODORANT IN PROPANE GAS CAN BE REDUCED BY IRON OXIDE (RUST), A GAS
DETECTING WARNING DEVICE IS THE ONLY RELIABLE METHOD TO DETECT
PROPANE GAS LEAKS.
OPERATING INSTRUCTIONS
ELECTRICAL COMPONENTS ARE CONTAINED IN BOTH COMPARTMENTS.
TO AVOID PERSONAL INJURY, ELECTRICAL SHOCK OR DEATH, DO NOT
REMOVE ANY INTERNAL COMPARTMENT COVERS. CONTACT A
QUALIFIED SERVICER AT ONCE IF AN ABNORMAL CONDITION IS NOTICED.
AN UNDETECTED GAS LEAK CAN CREATE A DANGER OF EXPLOSION
OR FIRE. THE UNIT AND ITS GAS CONNECTIONS MUST BE LEAK TESTED
BEFORE PLACING IN OPERATION.
HEATING START UP
To put your unit into operation, follow the steps listed below.
1. Close the external manual gas shutoff valve.
2. Turn off the electrical power to the unit.
3. Set the room thermostat to the lowest possible setting.
4. Remove the heat exchanger door on the side of the unit by
removing screws.
5. This unit is equipped with an ignition device which automati-
cally lights the burner. Do not try to light the burner by hand.
6. Move the gas control switch to the OFF position. Do not use
excessive force.
7. Wait five minutes to clear out any gas. Then smell for gas,
including near the floor as some types of gas are heavier than
air.
8. If you smell gas following the five minute waiting period in step
7, immediately follow the instructions on the cover of this manual.
If you do not smell gas after five minutes, move or rotate the
gas control switch to the ON position. The switch should turn
easily. Do not use excessive force.
9. Reinstall the burner compartment door.
10. Open the external manual gas shutoff valve.
11. Turn on the electrical power to the unit.
12. Adjust the thermostat to a setting above room temperature.
13. After the burners are lit, set the thermostat to desired temperature.
HEATING SHUT DOWN

COOLING OPERATION
Cooling operation may be obtained as follows:
1. Place the room thermostat selector switch in the COOL position {or
AUTO, if available, and if automatic changeover from cooling to heat-
ing is desired).
2. Set the room thermostat to the desired temperature.
3. If cooling system does not energize, wait five minutes. The system
startup may be delayed by the short-cycle protector feature of the
ignition control board. Check the manual reset devices on the rollout
limit, as described in this manual.
SAFETY CIRCUITS
A number of safety circuits are employed to ensure safe and proper unit
operation. These circuits serve to control any potential safety hazards
and, as inputs in the monitoring and diagnosis of abnormal operation.
