WARNING
To avoid property damage, personal injury or death due to
fire or explosion caused by a propane gas leak, install a gas
detecting warning device. If the propane gas unit is installed
in an excavated area or a confined space, 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 five feet 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
thermostat for mounting instructions.
All units have two stages of heating and two stages of
mechanical cooling. Units which will have economizers
may use thermostats with two or three stages of cooling.
All units can use single stage or multi-stage thermostats.
Refer to figures later in this section for wiring.
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. The low voltage
wiring must be connected between the unit control panel
and the room thermostat.
WARNING
To avoid personal injury, electrical shock or death,
disconnect electrical power before servicing or changing
any electrical wiring.
Single Stage Thermostat
WARNING
HIGH VOLTAGE!
Disconnect all power before servicing or
installing this unit. Multiple power sources
may be present. Failure to do so may cause
property damage, personal injury or death.
