TO THE INSTALLER In the U.S.A., this furnace may be used as a construction site heater ONLY if all of the following conditions are met: • The vent system is permanently installed per these installation instructions. • A room thermostat is used to control the furnace. Fixed jumpers that provide continuous heating CANNOT be used and can cause long term equipment damage. Bimetal thermostats, or any thermostat affected by vibration, must not be used during construction.
PAGE 6
A copy of the National Fuel Gas Code (NFPA 54/ANSI Z223.1) can be obtained from any of the following: • American National Standards Institute 23 West 43rd Street, 4th Floor New York, NY 10036 National Fire Protection Association 1 Batterymarch Park Quincy, MA 02169-7471 • CSA International 8501 East Pleasant Valley Independence, OH 441311 • The rated heating capacity of the furnace should be greater than or equal to the total heat loss of the area to be heated.
PAGE 7
• • • • • • • If the furnace is used in connection with a cooling coil unit, install the furnace upstream or in parallel with the cooling coil unit. Premature heat exchanger failure will result if the cooling unit is placed ahead of the furnace. For vertical (upflow or downflow) applications, the minimum cooling coil width shall not be less than furnace width minus 1”.

MATERIALS AND JOINING METHODS takes place. Because of the relatively low flue gas temperature and water condensation requirements, PVC or ABS pipe is typically used as venting and intake pipe materials. In Canada ABS is not an approved vent pipe material but it is permissable to use as combustion air pipe material. Two-three-inch nominal diameter PVC Schedule 40 pipe meeting ASTM D1785, PVC primer meeting ASTM F656, and PVC solvent cement meeting ASTM D2564 specifications must be used.
PAGE 12
Precautions should be taken to prevent condensate from freezing inside the vent/flue pipe and/or at the vent/flue pipe termination. All vent/flue piping exposed to freezing temperatures below 35°F for extended periods of time must be insulated with 1/2” thick closed cell foam. Also all vent/flue piping exposed outdoors in excess of the terminations shown in this manual (or in unheated areas) must be insulated with 1/2” thick closed cell foam. Inspect piping for leaks prior to installing insulation.
PAGE 13
• • • STANDARD FURNACE CONNECTIONS The vent termination of vent pipe run vertically through a roof must terminate at least 12 inches above the roof line (or the anticipated snow level) and be at least 12 inches from any vertical wall (including any anticipated snow build up). A vent termination shall not terminate over public walkways or over an area where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valves, or other equipment.
PAGE 14
counterflow rubber coupling allows service removal of air intake piping internal to the furnace blower compartment. The combustion air intake pipe can also be secured directly to the counterflow unit air intake pipe coupling. NON-DIRECT VENT INSTALLATIONS A minimum of one 90° elbow should be installed on the combustion air intake “coupling” to guard against inadvertent blockage. VENT-DRAIN WARNING THE RUBBER ELBOW IS NOT DESIGNED TO SUPPORT A LOAD.
PAGE 15
ALTERNATE COMBUSTION AIR PROVISION (Upflow / Horizontal models only) When using the alternate venting location, either in a horizontal left side down installation or a vertical installation using down – venting, an alternate combustion air opening can be used. A locating dimple is located on the right side of the furnace cabinet. The locating dimple is 1 7/8" measured from the front edge of the cabinet in line with the knock out. To use the alternate combustion air location: 1.

For satisfactory operation, propane gas pressure must be 10” WC at the furnace manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors: 1. Vaporization rate, depending on temperature of the liquid, and “wetted surface” area of the container or containers. 2. Proper pressure regulation. (Two-stage regulation is recommended for both cost and efficiency). 3. Pressure drop in lines between regulators, and between second stage regulator and the appliance.
PAGE 31
When the furnace is used in connection with a cooling unit, the furnace should be installed in parallel with or on the upstream side of the cooling unit to avoid condensation in the heating element. With a parallel flow arrangement, the dampers or other means used to control the flow of air must be adequate to prevent chilled air from entering the furnace and, if manually operated, must be equipped with means to prevent operation of either unit unless the damper is in the full heat or cool position.

6. Wait five minutes then smell for gas. Be sure check near the floor as some types of gas are heavier than air. 7. If you smell gas after five minutes, immediately follow the safety instructions in the Safety Considerations on page 3 of this manual. If you do not smell gas after five minutes, move the furnace gas valve manual control to the ON position. 8. Replace the burner compartment door. 9. Open the manual gas shutoff valve external to the furnace. 10. Turn on the electrical power to the furnace. 11.
PAGE 34
GAS MANIFOLD PRESSURE MEASUREMENT AND ADJUSTMENT indicates 1/2 cu. ft. per revolution. You will use this number to calculate the quantity of gas in cubic ft. if the furnace would consume if it ran steadily for one hour (3600 seconds). 3. If the 1/2 cu. ft. dial was used, multiply your number x 2. Only small variations in gas pressure should be made by adjusting the gas valve pressure regulator. The manifold pressure must be measured with the burners operating.
PAGE 35
If heating and cooling blower speeds are the same, a jumper wire must be used between the heat and cool terminals. 4. Connect all unused blower motor leads to the “PARK” terminals on the integrated control module. Any leads not connected to the “PARK” terminals must be taped. 5. Turn ON power to furnace. 6. Verify proper temperature rise as outlined in the Temperature Rise section of Startup Procedure and Adjustment.
