instructions thoroughly before installing or

servicing this equipment.

2. Do not locate ANY gas-fired units in areas

where chlorinated, halogenated, or acid

vapors are present in the atmosphere.

These substances can cause premature

heat exchanger failure due to corrosion,

which can cause property damage, serious

injury, or death.

special precautions / SI (METRIC) CONVERSION FACTORS BEFORE YOU BEGIN CAUTION 17. When leak testing the gas supply piping system, the appliance and its combination gas control must be isolated during any pressure testing in excess of 14" W.C. (1/2 psi). 18. The unit should be isolated from the gas supply piping system by closing its field installed manual shut-off valve. This manual shut-off valve should be located within 6' of the heater. 19. Turn off all gas before installing appliance. 20.

Do not install units below 7' measured from the bottom of the unit to the floor in commercial applications (unless unit is properly guarded to provide user protection from moving parts) and 5' measured from the bottom of the unit to the floor in residential applications. 2. Be sure no obstructions block air intake and discharge of unit heaters. 3.

installation - venting A4. A minimum of 12" straight pipe is recommended from the flue outlet before turns in the vent pipe. A5. Horizontal sections of vent pipe are to be installed with a minimum downward slope from the appliance of 1/4 inch per foot and suspended securely from overhead structures at points not greater than 3' apart. A6. Fasten individual lengths of vent together with at least three corrosion resistant sheet metal screws. A7.

installation - venting A10. The following are General Instructions for Double Wall (type B) Terminal Pipe Installation: How to attach a single wall vent terminal to double wall (type B) vent pipe: 1. Look for the “flow” arrow on the vent pipe. 2. Slide the vent terminal inside the exhaust end of the double wall vent pipe. 3. Drill (3) holes through the pipe and the vent terminal. Using 3/4" long sheet metal screws, attach the cap to the pipe. Do not over tighten.

installation - venting Section B – Vertical Vent System Installation B1. This section applies to vertically vented Category I vent systems and is in addition to “Section A – General Instructions – All Units”. B2. Vertical vent systems terminate vertically. B3. The horizontal portion of the vent run cannot exceed 75% of the vertical rise (Example: If the vent height is 10 feet, the horizontal portion of the vent system cannot exceed 7.5 feet). B4.
PAGE 9
installation - venting • For single wall vent pipe and 10’ or greater horizontal distance to any portion of a building, the vent must terminate at least 3’ (2’ for non-residential installations) above the highest point where it passes through a roof of a building and at least 2’ higher than any portion of a building within a horizontal distance of 10’. See Figure 9.1 Figure 9.

This section applies to horizontally vented Category III vent systems and is in addition to “Section A – General Instructions – All Units”. C2. All heaters that are horizontally vented with 3" (for sizes 30-75) or 4" (for sizes 100 and 125) vent pipe perform as a Category III appliance.
PAGE 11
installation - venting Additional Requirements for Common Venting: 1. The common vent system and all attached appliances must be Category I. 2. The vent connector should be routed in the most direct route from the units to the common vent. 3. Where two or more vent connectors enter a common gas vent or chimney flue, the smaller connector shall enter at the highest level consistent with the available head room or clearance to combustible material. 4.

installation - operation OPERATION Prior to Operation important 1. To prevent premature heat exchanger failure, observe heat exchanger tubes. If the bottom of the tubes become red while blower and furnace are in operation, check to be sure the blower has been set to the proper RPM for the application. Refer to page 14 for Wiring Adjustments for Blower Motors. 2. Start-up and adjustment procedures should be performed by a qualified service agency.

CONTROL OPERATING SEQUENCE / unit components CONTROL OPERATING SEQUENCE Upon a call for heat from the thermostat, power is supplied to the power exhauster motor. The unit will go through a purge period and then the direct spark igniter will be energized. At the same time, the main valve in the combination control valve will open to allow gas to flow to the burners. If the fan motor has not all ready started it will start shortly.
