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 NOx unit (designated by an L in the model number) to propane, the NOx inserts must be 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.

CAUTION

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.
