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.
ELECTRICAL WIRING
Thermostat Location
Mount the thermostat approximately 5 ft (1.5 m) above the floor,
in an area that has an inside, vibration-free wall and has good air
circulation.
Movement of air must not be obstructed by furniture, door,
draperies, etc. The thermostat must not be mounted where it will
be affected by drafts, hot or cold water pipes or air ducts in walls,
radiant heat from fireplace, lamps, the sun, television, etc.
Consult the Instruction Sheet packaged with the thermostat for
mounting instructions.
All units have 1 stage of heating and 1 stage of mechanical
cooling. Units which will have economizers may use thermostats
with 1 or 2 stages of cooling.
WARNING
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Goodman 42
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
The units are designed for operation on 60 hertz current and at
voltages as shown on the rating plate. All internal wiring in the
unit is complete. It is necessary to bring in the power supply to
the contactor as shown on the unit wiring diagram which is
supplied with each unit. 24-volt wiring must be connected
between the unit control panel and the room thermostat.

Refer to the unit wiring diagram for electrical connections. When
installed, the unit must be electrically grounded in accordance
with local codes or in the absence of local codes, with the
National Electrical Code, ANSI/NFPA No. 70, and/or the CSA
C22.1 Electrical Code. Ensure that the low voltage connections
are waterproof.
WARNING
Goodman 70
To avoid the risk of electrical shock, wiring to the unit
must be polarized and grounded.
WARNING
Goodman 22
To avoid the risk of fire or equipment damage, use
copper conductors.
CAUTION
Goodman 59
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
For unit protection, use a time-delay fuse or HACR circuit breaker
that is in excess of the circuit ampacity, but less than or equal to
the maximum overcurrent protection device.
IMPORTANT: Do not exceed the maximum overcurrent device
size shown on the unit data plate.
All line voltage connections must be made through weatherproof
fittings. All exterior power supply and ground wiring must be in
approved weatherproof conduit. Low voltage wiring from the unit
control panel to the thermostat requires coded cable.
Electrical Power Directly to Junction Box
NOTE: Junction box location shown is optional and is for
illustration purposes only.
