Sizing Between First and Second Stage Regulator
Maximum Propane Capacities listed are based on 1 PSIG Pressure Drop at 10
PSIG Setting, Capacities in 1.000 BTU/HR
Table 3 - Propane Gas Pipe Sizing
TO PREVENT PROPERTY DAMAGE OR SERIOUS PERSONAL INJURY 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 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 one stage of heating and one stage of mechanical
cooling. Units which will have economizers may use thermostats
with one or two stages of cooling.
To AVOID INJURY, ELECTRICAL SHOCK OR DEATH, DISCONNECT ELECTRICAL
POWER BEFORE SERVICING OR CHANGING ANY ELECTRICAL 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- 24 volt wiring must be connected
between the unit control panel and the room thermostat.
Low Voltage Wiring
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 low voltage connections are
waterproof.
TO AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO THE UNIT MUST BE
POLARIZED AND GROUNDED.
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY DUE TO FIRE, USE
ONLY COPPER CONDUCTORS.
TO PREVENT IMPROPER AND DANGEROUS OPERATION DUE TO WIRING ERRORS,
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS.
VERIFY PROPER OPERATION AFTER SERVICING.
For unit protection, use a fuse or HACR circuit breaker that is in
excess of the circuit ampacity, but less than or equal to the
maximum overcurrent protection device. DO NOT EXCEED THE
MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT
DATA PLATE.
