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 in. W.C. (3.5 kPa). All piping should be sized in accordance with the latest edition of ANSI Standard Z223.1 National Fuel Gas Code; in Canada, according to CGA-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.

VENTING* All unit heaters must be vented! All Venting installations shall be in accordance with the latest edition of Part 7, Venting of Equipment of the National Fuel Gas Code, ANSI Z223.1, or applicable provisions of local building codes. Refer to notes* below for Canadian installations. Refer to Figures 12-19. CARBON MONOXIDE! Your venting system must not be blocked by any snow, snow drifts, or any foreign matter.
VENTING - GENERAL GUIDELINES ANSI now organizes vented appliances into four categories. The following guidelines apply to all categories to follow. Venting Categories Table 4 Vent Systems Termination Clearance Requirements Structure Negative Vent Pressure Positive Vent Pressure Minimum Clearances for Termination Locations 4 feet below Door, window or any gravity vent inlet 4 feet horizontally Non Condensing Condensing I II III IV 1 foot above Forced air inlet within 10 ft.
STANDARD COMBUSTION VERTICALLY VENTED, CATEGORY I - Figure 12 Observe the following precautions when venting the unit: 1. Use flue pipe of the same size as the flue connection(s) on the gas unit heater 4" (102mm). All heaters must be vented with a UL Listed, Type B or single wall vent, a factory built chimney, or a lined brick and mortar chimney that has been constructed in accordance with the National Building Code.

STANDARD COMBUSTION VERTICALLY VENTED, CATEGORY III – Figure 17 & 19 Observe the following precautions when venting the unit: 1. Use flue pipe of the same size as the flue connection(s) on the gas unit heater, 4" (102mm). All heaters must be vented with a single or double wall pipe listed for positive pressure vent systems. 2. Each unit must have an individual vent pipe and vent terminal. Unit MUST NOT be connected to other vent systems or to a chimney. 3.

SEPARARTED COMBUSTION INSTALLATION - VENTING – CATEGORY III COMBUSTION AIR VENTING AND PIPING 5. Long runs of single wall combustion air piping passing through an unheated space may require insulating if condensation becomes noticeable. 6. The combustion air system must be installed to prevent collection of condensate. Pitch horizontal pipes downward 1/4 inch per foot toward the inlet cap to facilitate drainage. Vertical combustion air pipes should be piped as depicted in Figure 22. 7.
SEPARATED COMBUSTION VENTING (continued) 4. Use single wall pipe constructed of 26 GA galvanized NOTICE: Increasing the clearance distances may steel or a material of equivalent durability and corrosion be necessary if there is a possibility of distortion or resistance for the vent system. For installations in discoloration of adjacent materials. Canada, use corrosion resistant and gas-tight, listed vent pipe conforming with local building codes, or 11.

SEPARATED COMBUSTION VENTING (continued) HORIZONTAL TERMINATION Select a location on outside wall for vent terminal. In most applications, the terminal should be on level with the flue outlet of the unit less a 1/4 inch per foot pitch for condensate drainage toward the outside of the building. See Figure 23. AIR INLET COLLAR Remove screen and mounting plate from air inlet on rear panel of unit by removing 4 screws. Secure inlet collar and gasket to inlet opening re-using the 4 screws removed in step one.
OPERATION POWER VENTED PROPELLER UNITS DIRECT SPARK IGNITION EXPLANATION OF CONTROLS (See Figure 25): 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 SHUTTER 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). 2. PROPANE GAS: An exact manifold pressure of 10.0 inches W.C. (2.5 kPa) must be maintained for proper operation of the unit heater. If the unit is equipped with a pressure regulator on the combination gas valve, follow steps "a" through "d" above.
