Resumen del manual
Next, position the blower in the filter box, centered behind the inlet hole and allow approximately 1/8 in. space between the rear of the furnace and the blower outlet. Now, install the filter rail onto the filter box. NOTE: The filter rail is best installed on the side toward the shaker handle, so that any pipes from the hot water coil do not interfere with filter installation or removal. NOTE: Before proceeding with the installation of the access door, it is suggested that the wiring be completed. The access door is installed by slipping the flange on the bottom of the access door over the bottom rail of the filter box opening, then push the top of the door against the top of the filter box opening and secure with a sheet metal screw. Filter box mounting clips Figure 2 1/8 in. space between blower and furnace Furnace Installation - Wiring Wiring Before beginning any wiring, study the appropriate wiring diagram for your unit. Also refer back to figures C or D for an example of what the completed job will look like. It is your reponsibility to follow all state and local electrical codes. Locate the best place to route the power for the blower, and drill a 7/8” hole in the filter box. This hole size will accomodate a “romex” connector. Attach the blower and power wires as shown on the appropriate wiring diagram. Once you have the plenum installed, the fan control with high limit switch can be installed. The Fan control/high limit switch is packaged with a jumper between the two sets of terminals inside. REMOVE THE JUMPER WIRE INSIDE THE FAN CONTROL. The fan control should be installed in the right side of the plenum and 12 to 18 inches above the top of the furnace. A separate conduit should be run from the fan control to the junction box. Mount the thermostat in a central location of the area you want to heat. Run two wires to the junction box, from the heating terminals on the thermostat. 22 gauge or thicker wire is acceptable. The next step is to run a 120 volt line from your breaker panel to the junction box. Attach all wires according to the corresponding wiring diagram, and install the relay into the junction box. DO NOT TURN ON THE BREAKER UNTIL ALL WIRING IS COMPLETE AND THE RELAY IS SECURED.

This figure shows a typical duct system layout. Be sure the entire system is properly sized to provide the correct static pressure for optimum blower performance. Have any new duct system designed by a HVAC professional. Operating Instructions Adjusting Automatic Draft Control - In order for your new furnace to function, the controls must be properly adjusted. The heat output is regulated by the automatic draft control, on the bottom door of the furnace. Refer to the illustrations at right; The electric draft motor (A) opens and closes the flapper door (B). The flapper door opens to feed more air to the fire and closes to reduce the air to the fire. The maximum air flow can be adjusted by turning the adjuster bolt (C) counter-clockwise for more air and clockwise for less air. NOTE: To preserve motor life, all adjustments of this bolt should be done while the flapper door is in the closed position. The idle adjuster (D) controls the minimum amount of air that enters the firebox when the flapper door is closed. Adjustment is made by turning the adjuster vertical for zero air, or horizontal for maximum idle air. It is best to start at a medium setting as shown at right. Adjusting the fan control- Shut off the power at the circuit breaker before removing the fan control cover. Make sure the copper jumper (circled below) is removed before using the furnace. Note the three pointers on the dial. The one on the right is the high limit adjustment. Pre-set at 200 degrees, it’s function is to close the automatic draft control flapper door if the temperature in the plenum reaches 200 degrees. Do not change this setting. The center pointer adjusts the temperature at which the blower starts. A good initial setting for this is 150 degrees. The pointer on the left is to adjust the temperature at which the blower stops. A good initial setting for this pointer is 100 to 110 degrees. If it is set too low, the air will feel cool coming out of the registers at the end of the blower cycle. Thermostat- Set the thermostat to the desired temperature. When more heat is needed, the thermostat opens the automatic draft control flapper door. This allows air into the firebox, which raises the output of the fire. When the temperature in the plenum reaches the set temperature of the center pointer on the fan control, the blower will begin blowing heated air through the ductwork. When the thermostat reaches it’s setpoint, the automatic draft control closes the flapper door, thus, reducing the output of the fire. As the temperature in the plenum drops to the set point of the left ...
