A Word From The Manufacturer Dear Customer, To set up our furnace assembly procedures, several hundred quafity assurance, safety audit and design performance tests have been conducted according to the standards provided by the American National Standards Institute, the Department of Energy and our certification agency -- the American Gas Association Laboratories. This was done to assure you of receiving the best value and most reliable appliance of its type available today.
Safety Rules WARNING umn. The maximum inlet gas supply pressure is 13" water column. READ THESE RULES AND THE INSTRUCTIONS CAREFULLY. FAILURE TO FOLLOW THESE RULES AND INSTRUCTIONS COULD CAUSE A MALFUNCTION OF THE FURNACE. THIS COULD RESULT IN DEATH, SERIOUS BODILY INJURY, AND/OR PROPERTY DAMAGE. 7. ANY SAFETY SCREEN, GUARD OR PARTS REMOVED FOR SERVICING AN APPLIANCE MUST BE REPLACED PRIOR TO OPERATING THE APPLIANCE TO AVOID PROPERTY DAMAGE, BODILY INJURY OR DEATH.
Unpack Your Furnace The shipping carton contains the furnace and the items needed to install it: 4. Stand Furnace upright. 5. Properly dispose of shipping material. The furnace is shipped assembled. The cabinet must be removed for the furnace installation. NOTE Check the burner rating plate, located in burner compartment, to make sure your furnace is equipped to operate on the type of gas available (either Natural or L.P. Gas). DO NOT convert unit from Natural Gas to L.R Gas or from L.
Installing Your Wall Furnace The following steps are all needed for proper installation and safe operation of your furnace. If you have any doubts as to any requirements, check with local authorities. Obtain professional help where needed. Locating All of CHECKS AND ADJUSTMENTS in the Start-Up Procedure on page 17 are vital to the proper and safe operation of the furnace. Be sure they are done.
Combustion & Ventilation Air WARNING WARNING DANGER OF ILLNESS BODILY INJURY OR DEATH THE FURNACE AND ANY OTHER FUEL BURNING APPLIANCE MUST BE PROVIDED WITH ENOUGH FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF FLUE GASES. MOST HOMES WILL REQUIRE THAT OUTSIDE AIR BE SUPPLIED INTO THE FURNACE AREA.
Combustion To determine if infiltration following checks: & Ventilation air is adequate, perform the Air (Con't) Provide an opening(s) having a total free area of 1 sq. inch per 4000 Btuh of the total of all appliances. The required area is shown in Fig. 7, page 9. 1. Close all doors and windows. 11you have a fireplace, start a fire and wait until flames are burning vigorously, (or flue damper can be closed), FRESH AIR DUCT 2.
Combustion & Ventilation A. All Air From Inside Building: If the confined space adjoins an unconfined space as defined in EXAMPLE 1, provide two permanent openings, one within 12 inches of the top and one within 12 inches of the bottom of the room connecting directly to unconfined space. Each opening must have a free area of at least 100 square inches or 1 square inch per 1000 Btuh combined input of appliances in one room if combined input exceeds 100,000 Btuh.
Recessed Mount NOTE: Model Series 25096 and 35096. The maximum recess depth, from rear of furnace forward is 41/=''. Installation rear outlet plasterground at the same time you install the header plate. For existing construction, make necessary cutout and install the plasterground just before you install the furnace. See instructions packed with kit and Fig. 8. FIND THE STUDS AND CEILING JOISTS Use a stud Iocator or small finishing nails.

Surface Mount Installation Vent Installation The use of optional Free Standing Kit No. 4901 allows furnace to be mounted on the surface of a wall. See detailed instructions packed with kit. Vent Installation The vent installation must comply with all local codes and ordinances. If in doubt, consult your local codes or inspector. The furnace vent must be directed to the outdoors so that harmful combustion gasses will not collect inside the building.

Gas Supply and Piping Gas control valve, within the furnace, is shipped with a sealed cover gas inlet tapping. Do not remove seal until ready to connect piping. WARNING DANGER OF PROPERTY DAMAGE, BODILY INJURY OR DEATH. MAKE SURE THE FURNACE IS EQUIPPED TO OPERATE ON THE TYPE OF GAS AVAILABLE. MODELS DESIGNATED AS NATURAL GAS ARE TO BE USED WITH NATURAL GAS ONLY. FURNACE DESIGNATED FOR USE WITH LIQUEFIED PETROLEUM (L.P.) GAS HAVE ORIFICES SIZED FOR COMMERCIALLY PURE PROPANE GAS.
Gas Supply CHECKING and Piping (Con't) THE GAS PIPING GAS PIPE SIZES Test all piping for leaks. When checking gas piping to the furnace with gas pressure at less than 1/2 PSI, shut off manual gas valve for the furnace, if gas piping is to be checked with the pressure at or above 1/2PSI, the furnace and manual shut off valve must be disconnected during testing. (SEE WARNING BELOW.) Apply soapsuds (or a liquid detergent) to each joint. Bubbles forming indicates a leak.
Thermostat MOUNTING Installation (Con't) THE THERMOSTAT ROUTE THERMOSTAT CABLE 1. To remove thermostat cover, squeeze both sides and lift. Carefully remove and discard the packing tab protecting the switch contacts. 2. Connect thermostat wires to the terminal screws on the back of thermostat base. 3. Push any excess wire back through hole in wall and plug hole with insulation to prevent drafts from affecting thermostat operation. 4.
