Use wood strips nailed to inside of studs and top of bottom plate. These must be removed before installation of furnace. Lath and plaster against top projection of Header Plate. Do not allow wall . nish materials to project into furnace recess.. Figure 4 Installing Furnace (Figure 5) Clear the recess of all debris, and remove any wood plaster-grounds. Stand the furnace on . oor in front of wall opening. Insert furnace . ue into rectangular opening in header plate and raise furnace carefully (see Figure 5). Swing bottom of furnace into wall opening with back of legs . ush with rear of . oor plate. Secure furnace support legs to the . oor plate. Figure 5 Page 10 12426-4-0104 IMPORTANT . Avoid securing too tightly and disturbing the inner casing. Do not try to force furnace into a wall opening which is smaller than speci. ed dimension. OUTER CASING (Figure 6) 1. Align 1 3/4" slot on casing bracket with bottom screw hole on inner casing. Attach casing bracket to inner casing with one (1) 10 x 1/2" screws for each casing bracket. Do not completely tighten screws at this time. 2. Place outer casing onto header. Attention: Use center clearance hole on outer casing top for attachment to header with one (1) 8 x 3/8" Phillips screw when optional blower is not installed. Attention: Use outside clearance holes on outer casing top for attachment to header with two (2) 8 x 3/8" Phillips screws when optional blower is installed. 3.

FINISHING INSTRUCTIONS (continued) Figure 6 THERMOSTAT LOCATION (SG MODELS) THERMOSTAT LOCATION (SG MODELS) CAUTION . Do not run wire behind .anges of Header Plate Connect thermostat wires to gas valve as shown in Figure 7. or in any location where it might be damaged. Millivolt wall thermostats are specially designed for use on self- generating systems. They should never be used on line or low voltage A.C. circuits. Interior Wall . The thermostat should be installed on an inside wall away from the furnace but in the same room. Note: Use 16 gauge wire to prevent excessive loss of millivolts. Proper operation depends on a good pilot . ame. The . ame must cover the top of the thermopile. Cleaning of the pilot ori. ce and burner may be required due to spiders. Figure 7 System Check (Figure 7) A millivolt meter is required to check the system. Millivolt readings should be: . Across the thermopile terminals, 400-450 millivolts with thermostat OFF. . Across the thermopile terminals, 150-250 millivolts with thermostat ON. . Across the thermostat wires at the valve, less than 30 millivolts with thermostat ON. . Across the thermostat wires at the thermostat, less than 5 millivolts with thermostat ON. (Dirty pilot or low pressure will reduce readings.) 12426-4-0104 Page 11 LIGHTING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a .re or explosion may result causing property damage, personal injury or loss of life.
