GENERAL SAFETY INFORMATION Failure to comply with the general safety information may result in extensive property damage, severe personal injury, or death. Make certain that the power source conforms to the electrical requirements of the heater. Do not depend upon a thermostat or other switch as sole means of disconnecting power when installing or servicing heater. Always disconnect power at main circuit breaker as described above. Failure to do so could result in fatal electric shock.

INSTALLATION Do not install unit heaters in corrosive or flammable atmospheres! Premature failure of, or severe damage to the unit will result! AIR FOR COMBUSTION: The unit heater shall be installed in a location in which the facilities for ventilation permit satisfactory combustion of gas, proper venting, and the maintenance of ambient air at safe limits under normal conditions of use.
INSTALLATION (continued) The Unit Heater may be mounted by fastening the hanging brackets directly to ceiling joists or by suspending from four rods. See Figures 3, 4 and 5. Figure 3 - Hanger Bracket Installation Instructions Make certain that the lifting methods used to lift the heater and the method of suspension used in the field installation of the heater are capable of uniformly supporting the weight of the heater at all times.
GAS PIPING To avoid damage or possible personal injury, do not connect gas piping to this unit until a supply line pressure/leak test has been completed. Connecting the unit before completing the pressure/leak test may damage the unit gas valve and result in a fire hazard. Do not rely on a shut-off valve to isolate the unit while conducting gas pressure/leak tests. These valves may not be completely shut off, exposing the gas valve to excessive pressure and damage.
PIPE INSTALLATION 1. Install the gas piping in accordance with applicable local codes. 2. Check gas supply pressure. Each unit heater must be connected to a gas supply capable of supplying its full rated capacity as specified in Table 3. A field LP tank regulator must be used to limit the supply pressure to a maximum of 14 inches W.C. (3.5 kPa). All piping should be sized in accordance with the latest edition of ANSI Standard Z223.1 (NFPA 54) National Fuel Gas Code; in Canada, according to CSA-B149.
ELECTRICAL CONNECTIONS THERMOSTAT WIRING AND LOCATION: NOTICE: The thermostat must be mounted on a vertical, vibration-free surface, free from air currents, and in accordance with the furnished instructions. HAZARDOUS VOLTAGE! DISCONNECT ALL ELECTRIC POWER INCLUDING REMOTE DISCONNECTS BEFORE SERVICING. Failure to disconnect power before servicing can cause severe personal injury or death. Standard units are shipped for use on 115 volt, 60 hertz, single phase electric power.

OPERATION POWER VENTED PROPELLER UNITS DIRECT SPARK IGNITION EXPLANATION OF CONTROLS: 1. Each Unit Heater comes equipped with a power vent system that consists of a power venter motor and blower, pressure switch, and sealed flue collector in place of the conventional draft diverter. 2. The power venter motor is energized by the room thermostat through the integrated control board when a demand for heat is sensed.
PRIMARY AIR ADJUSTMENT Primary air adjustment is made at the factory. No field adjustments are necessary. GAS INPUT RATE Check the gas input rate as follows (Refer to General Safety Information section for metric conversions). Never overfire the unit heater, as this may cause unsatisfactory operation, or shorten the life of the heater. 1. Turn off all gas appliances that use gas through the same meter as the unit heater. 2. Turn the gas on to the unit heater. 3.
