Installation (continued) 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 temperature at safe limits under normal conditions of use. The unit heater shall be located in such a manner as not to interfere with proper circulation of air within the confined space.
Installation (continued) Gas Piping WARNING 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. WARNING 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.
Installation (continued) Pipe Installation 1. Install the gas piping in accordance with applicable local codes. Figure 4 - Pipe Installation, Standard Controls 2. Check gas supply pressure. Each unit heater must be connected to a manifold pressure and a gas supply capable of supplying its full rated capacity as specified in Table 4. A field LP tank regulator must be used to limit the supply pressure to a maximum of 14 inches W.C. (3.5 kPa).
Blower Set Up and Adjustment BLOWER SET UP The drive ratio of the motor and blower sheaves has been preset at the factory for a temperature rise of 65°F at .2" W.C. If the unit is to be operated under different static air flow or pressure requirements, the drive ratio must be altered by means of the adjustable sheave on the blower motor. 1. Ensure that all packing material, support blocks, etc have been removed from the unit. 2.

Electrical Connections 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. The motor name-plate and electrical rating of the transformer should be checked before energizing the unit heater electrical system. All external wiring must conform to the latest edition of ANSI/NFPA No.

Venting ANSI now organizes vented appliances into four categories. Venting Categories Non Condensing Condensing Negative Vent I II Pressure Positive Vent III IV Pressure Category I Includes non-condensing appliances with negative vent pressure, like the traditional atmospheric unit heater. Category II Groups condensing appliances with negative vent pressure. Category IV Covers condensing appliances with positive vent pressure.
Venting (continued) Horizontally Vented Unit Heaters (Category III) Horizontal venting arrangements are designed to be used with single wall vent pipe. Horizontal venting arrangements must terminate external to the building using UL 1738 Listed single wall or double wall vent. For installations in Canada, use corrosion resistant and gas-tight, listed vent pipe conforming with local building codes, or in the absence of local building codes, with current CSA-B149.

Operation Power Vented Blower Units Direct Spark Ignition EXPLANATION OF CONTROLS: 1. The unit heater is 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.
Operation (continued) 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). CAUTION 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. 2.
Operation (continued) TUBULAR UNIT HEATER HIGH ALTITUDE DERATION This Tubular Unit Heater has been manufactured utilizing standard burner orifices and a normal manifold pressure setting as per the specifications shown on your unit rating plate. in the field, attach label #J17-06459 to the unit, and record adjusted manifold pressure, altitude of the unit installation and the technician’s name and date on the label using a permanent marker.
