• DO NOT locate the appliance where heated air will be directed onto a nearby parked vehicle.
• Paint may discolor or rubber may harden and crack.
• DO NOT allow heated discharge air to blow directly onto open or closed containers of paint, gasoline or other liquids having flammable vapors.

LOCATIONS

1. This furnace must be installed on an outside wall and vented to the outside. If possible, this wall should be on the side of the house that receives the least amount of wind since strong gusting winds could cause a pilot outage.
2. For the most efficient performance, locate the furnace as centrally as possible in the area to be heated.
3. The furnace can be installed flush against a wall or recessed up to 10” maximum. For proper combustion, make sure the unit is level front-to-back and side-to-side.
4. Do not install the furnace in a closet, alcove, or small hallway where the furnace could be isolated from the space to be heated by closing a door.
5. Be sure the vent cap will have the proper clearances. (See Figure 2a)
6. Check inside the wall to make sure there are no obstacles such as water pipes, electric wiring, etc. which could interfere with the installation of the furnace or vent tubes.
7. Be sure to maintain adequate accessibility clearances for servicing and proper operation.
8. If the furnace is installed in a basement, a 12” clearance must be maintained between ground level and the bottom of the vent cap. Do not install a furnace where the vent cap will terminate in a window well or any other opening below ground level.

INSTALLATION

ELECTRICAL ROUGH-IN
For convenience, this furnace is equipped with a three-prong power cord located on the top left of the heater. The 115V wiring should be brought in on the left side terminating in a receptacle box (not provided). Consult local codes or ordinances. (For Amps, see Page 3 / Specifications and Dimensions).

ROUGH-IN GAS SUPPLY
Install a 1/2-inch diameter gas supply line. The gas line can enter the cabinet through the right side or bottom (See Figure 3). The gas line must have an individual manual shut-off valve. Also, you must install a drip leg and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge connection, immediately upstream of the gas supply connection
to the furnace (See Figure 4).
The furnace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½  psig (3.5kPa). The furnace must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply
the piping system at test pressures equal to or less than ½ psig (3.5kPa).

LOCATE VENT OPENING
After the location of the heater has been determined, the opening for the vent pipe should be cut. If the heater is to be recessed, cut out the opening for the heater between studs on the interior wall and cut out the floor plate between the studs, so the heater will be set flat on the floor as all dimensions are given from a finished floor. The height of the cutout for a 40,000 BTU model is 78-5/8”, for the 55,000 models the cutout height is 87-5/16”. NOTE: This dimension may be increased to allow more room for installation and making the wiring connection, then refinished.

Next, cut out a 9-1/4” opening in the exterior wall for the vent tubes to pass through. The center of opening for the 40,000 BTU furnace is 59”, and the center opening for the 55,000  BTU furnace is 68-1/2”. See Figure 5, on Page 6.

If the heater is to be surfaced mounted, cut out a 9-1/4” opening through the interior and exterior wall. The center of cut out will be 59” for 40,000 BTU and 68-1/2” for 55,000  BTU models. Be sure both cutouts are level with each other.

INSTALLING THE FURNACE
The vent system supplied with this furnace will accommodate walls ¾” (when recessed) up to 12” thick. Use only the exhaust tube, air intake tube, and vent cap supplied with the heater. Do not attempt to lengthen the exhaust or air intake tubes, this could cause an imbalance in the heater resulting in poor performance and pilot outage (See Figure 6).
Measure the exact distance “X” between the surface on which the back of the cabinet will rest (inside of the recessed cavity or face of the wall when freestanding) and the outside wall surface (see  Figure 6).

INLET AIR TUBE “A” – Measuring from gasket surface, mark and cut pipe same as dimension “X”.  Remove any burrs.

VENT EXHAUST TUBE “B” – Measuring from gasket surface, mark and cut pipe 1-3/4” greater than dimension “X”. Remove any burrs.

Fasten vent exhaust tube “B” to heat exchanger collar and Inlet AirTube “A” to flange on the back of furnace using 16 # 3/8 screws (“C”)provided. Be sure gaskets are in place and not damaged. Anytime the vent pipes are removed check and replace gaskets (if necessary). Failure to replace missing or damaged gaskets may expose homeowners to life-threatening conditions.
Secure the furnace in place using 2 holes provided in the bottom of the casing.NOTE: Make sure both tubes are centered in cut out. Slide the vent cap onto the pipes extending from the back of the furnace. A rotating or twisting motion will ease this installation. Secure the vent cap and vent cap spacer plate to the wall causing the vent tubes to have a slight downward pitch. This will prevent water from entering. Anchors (not provided) may be required. Caulk around vent cap spacer plate with caulking provided.
NOTE: Some framing may be necessary to provide a flat surface against the vent cap spacer plate and to prevent rain from entering the wall opening.

GAS CONNECTION
Make the gas connection between the manual shut-off valve and the furnace gas control valve with approved ½” connectors. Compounds used on threaded joints of gas piping shall be approved for use with Propane gas. The gas lines must be checked for leaks by the installer with soapy water or liquid detergent, never use an open flame. If connections are not exposed, a pressure test must be run. Be sure to disconnect the gas supply line from the appliance valve before pressure testing. The manifold pressure is pre-set at the factory and should be 3.5” w.c. for Natural Gas and  10” w.c. for Propane Gas. The minimum inlet pressure for Natural Gas is 4.5” w.c. and 11” w.c. for Propane  Gas, “for purpose of input adjustment”. The maximum inlet pressure should never exceed 7.0” w.c. on Natural Gas or 14” w.c. on Propane Gas.

THERMOSTAT INSTALLATION
Follow the instructions included with the thermostat. Select a location for the thermostat on an inside wall approximately 5 feet above the floor where it won’t be affected by heat or cold sources such as direct sunlight, televisions, fireplaces, hidden hot or cold water pipes, drafts, etc., and minimum of 4’ from the heater. The thermostat must never be placed in an adjacent room. Connect thermostat wires to the thermostat and mount them to the wall. Run a wire to the furnace and make connections to thermostat wires coming out of the top of the furnace. Use insulated staples (provided) to secure the wire to the wall.

OPERATION
This heater is equipped with a slow-opening gas control. On a call for heat, the gas valve does not snap open to full manifold pressure but opens with a gradual increase to normal manifold pressure. The time-lapse from the call for heat to normal operating pressure is two to five seconds. The slow-open feature assures a safe, less noisy ignition.
After the heat exchanger has warmed sufficiently, the fan will automatically come on to efficiently transfer the heat into the room.

   NOTE: Be sure the door gasket is not damaged and will affect a proper seal or a pilot outage will occur.

8. Connect wires back to the valve.

9. Connect the gas supply back to the valve.

10. Turn on the electricity to the furnace.

11. Follow lighting instructions, and replace the lower grille.

It is recommended that the furnace and all components be inspected at least annually by a qualified service technician. This should include the burner, pilot, heat exchanger, and vent system. Be sure that the flow of combustion and ventilation air is not obstructed.

IMPORTANT: Keep burner & control compartment clean. Vacuum control compartment at the start of the heating season and as often as needed.

PROPER BURNER FLAME

The burner flame may be observed by raising the sight glass cover. A proper flame will have a dark blue inner mantle that sits right on top of the burners with a lighter blue outer mantle rising above the burner (See Figure 9 on page 11).
There may be some yellow where the pilot flame and burner flame meet. There is no primary air adjustment on the burner, and the proper flame is assured since the correct manifold pressure and orifice has been done at the factory. NOTE: It is advised that the burner flames be checked at least twice during the heating season for any changes in burner flame characteristics.
The appliance area must be kept clear and free from combustible materials, gasoline, and other flammable vapors and liquids. This appliance is equipped only for altitudes 0- 2,000 feet. Heaters installed above 2,000 feet must be derated 4% for every 1,000 feet. For the proper orifice size, find the Model Number and elevation on the orifice chart.  Replace burner orifice. Orifice change must be completed by a qualified installer or service technician.
