WARNING
To prevent property damage or serious personal injury
due to fire or explosion caused by a propane gas leak,
Goodman 102
install a gas detecting warning device.
If the propane gas unit is installed in an excavated area
or a confined space, a warning device is required due to:
-Propane gas is heavier than air and any leaking gas
can settle in any low areas or confined spaces.
-Propane gas odorant may fade, making the gas
undetectable except with a warning device.
Start-up, Adjustments and Checks
Heating Start-up
This unit is equipped with an electronic ignition device to
automatically light the main burners. It also has a power vent
blower to exhaust combustion products.
On new installations, or if a major component has been replaced,
the operation of the unit must be checked.
Check unit operation as outlined in the following instructions. If
any sparking, odors or unusual sounds are encountered, turn off
electrical power and recheck for wiring errors or obstructions in
or near the blower motors. Duct covers must be removed before
operating unit.
Heat Anticipator Setting
Set the heat anticipator on the room thermostat to 0.4 amps to
obtain the proper number of heating cycles per hour and to
prevent the room temperature from overshooting the room
thermostat setting.

Rollout Protection Control
The rollout protection device opens, cutting power to the gas
control valve, if the flames from the burners are not properly
drawn into the heat exchanger. The rollout protection device is
located on the burner bracket. The reason for elevated
temperatures at the control should be determined and repaired
prior to resetting this manual reset control.
WARNING
To avoid property damage, personal injury or death due
to fire or explosion, a qualified servicer must investigate
the reason for the rollout protection device to open
before manually resetting the rollout protection device.
