LPG/Propane Units, Tanks, and Piping

Units are shipped equipped for natural gas, but can be

converted to LPG/propane in the field by an approved

licensed technician. If conversion is required, use the

approved conversion kit.

When converting a low NO

model number) to propane, the NO

removed. After removing the burners, remove the screw

holding each insert and pull the insert from the combustion

chamber. The screws must be reinstalled in the vest panel

after the inserts are removed.

All LPG/propane gas equipment must conform to the safety

standards of the National Fire Protection Association.

For satisfactory operation, LPG/propane gas pressure must

be a minimum of 11" w.c. at the unit under full load.

Complete information regarding tank sizing for vaporization,

recommended regulator settings, and pipe sizing is available

from most regulator manufacturers and LPG/propane gas

suppliers.

Check all connections for leaks when piping is completed,

using a soapy solution. Some soaps used for leak detection

are corrosive to certain metals. Carefully rinse piping

thoroughly after completing leak detection.

Electrical Wiring (See Figures 4 & 5)

All wiring should be done in accordance with the

National Electrical Code, ANSI/NFPA No. 70 (latest

edition); Canadian Electrical Code Part 1, CSA C22.1

(latest edition); or local codes where they prevail. Use

wiring with a temperature limitation of 75°C minimum. Run

the 208 or 230 volt, 60 hertz electric power supply through a

fused disconnect switch to the control box of the unit and

connect as shown in the wiring diagram located on the inside

of the control access panel.

Power supply to the unit must be N.E.C. Class 1, and must

comply with all applicable codes. A fused disconnect switch

should be field provided for the unit. The switch must be

separate from all other circuits. If any of the wire supplied

with the unit must be replaced, replacement wire must be of

the type shown on the wiring diagram. Electrical wiring must

be sized to carry minimum circuit ampacity marked on the

unit. Use copper conductors only. Each unit must be

wired with a separate branch circuit and be properly fused.

When connecting electrical power and control wiring to

the unit, waterproof type connectors must be used so that

water or moisture cannot be drawn into the unit during

normal operation.

Thermostat

The room thermostat should be located on an inside wall where

it will not be subject to drafts, sun exposure, or heat from

electrical fixtures or appliances. Follow the manufacturer's

instructions enclosed with thermostat for general installation

procedure. Color-coded insulated wires (#18 AWG) should

be used to connect the thermostat to the unit.

Four wires are required for cooling. The heat anticipator

setting is 0.75 amp.

Compressor

Units are shipped with compressor mountings factory-

adjusted and ready for operation.

Caution: Do not loosen compressor mounting bolts.
