wiring, terminating inside the junction box located on top of header plate for recessed, or in a receptacle box (not provided) for flush mount. Consult local codes or ordinances. See Figure 3.

Gas Supply Line GAS ROUGH-IN Check local codes for requirements as to the size and type of gas line required. See Figure 5 for location of gas inlet holes in furnace cabinet. Compounds used on threaded joints of gas pipe should be resistant to the action of liquefied petroleum gases. The gas line joints must be checked for leaks. This should be done with a soap solution – watching for bubbles on all connections. NEVER USE AN EXPOSED FLAME TO CHECK FOR LEAKS. A manual valve equipped with a 1/8” NPT plugged tapping accessible for test gauge connection should be installed immediately upstream of the gas supply connection to the appliance. Some codes and ordinances require that the manual valve be located outside the appliance. See Figure 4. The appliance 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 . psig. The appliance 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 piping system at test pressures equal to or less than . pig. It is required by the National Fuel Gas Code that a drip line be installed near the gas inlet. This should consist of a vertical length of pipe tee connected into the gas line that is capped on the bottom in which condensation and foreign particles may collect. cut off Pressure Tap valve FIGURE 4 1-1/2” Dia.

STEP 2.Make electrical connection of 115 V. wiring into junction box provided on top of header plate. STEP 3.Attach the base plate (purchased with the vent pipe) to the header plate using two No. 8 sheet-metal screws through the pre-punched holes. See Figure B. STEP 4.Square up and nail header plate in place between 2x4 studs placed on 16” centers (14-3/8” between studs). For distances from top of header plate to floor, see Figure 6. STEP 5.Remove double ceiling plate between studs. Install one ceiling plate spacer across the cut out in ceiling plate. Install vent pipe into position, be sure to lock bottom of vent pipe into the base plate. Nail second ceiling plate spacer in place. See Figure B. STEP 6.If the vent continues through additional stories within the 2x4-stud space, then fire stop spacers must be installed at the second and subsequent ceiling levels. See Figure C. STEP 7.To place furnace into position, grasp furnace and lift so furnace flue vent and header plate vent opening engage. Plug power cord from top of heater into receptacle on bottom of the header plate, see Figure 3. Run thermostat wire through a drilled hole into an adjacent stud space. Do not route it behind the header plate. To do so may cause the thermostat wiring to chaff resulting in the appliance operating continually. Connect thermostat wire with thermostat wires extending from top of heater. Lift furnace upward and swing bottom into wall, see Figure 7. Secure furnace in place using 2 holes provided in bottom of casing. STEP 8.Make gas connection using connector the same size as gas connection of furnace. CHECK ALL CONNECTIONS FOR GAS LEAKS WITH LEAK DETECTOR SOLUTION. DO NOT USE OPEN FLAME. STEP 9.Replace and fasten front panels to furnace. NOTE: FOR PROPER COMBUSTION, MAKE SURE UNITS ARE LEVEL FRONT TO BACK AND SIDE TO SIDE. INSTALLATION WHEN INSTALLED FLUSH TO WALL STEP 1.After locating furnace, cut 3-1/2”x12” rectangular hole in ceiling between ceiling joists. Make sure gasket is in position on the top of the furnace casing around the flue vent opening. Remove vent collar from top of header plate and place over flue extension and fasten to matching holes in casing top, using screws from header plate. Install B vent type base plate (not supplied) to top of vent collar. Install ceiling plate spacer to back wall, centered between studs. Install B type vent to top of furnace, terminating at least 12’ above the floor and at least 2’ above the roof line. STEP 2.Fasten furnace to wall. To secure top of furnace to wall, loosen top screws on back casing and raise tabs up. Tighten screws. Screw through hole in top of tabs into anchors (not provided). Secure bottom using two holes provided in bottom of casing. (Optional) Cover exposed vent with a vent enclosure kit, Part Number 16VE-A or 36VE-A (not included).
