Installation To ensure a safe installation, it is recommended that this furnace be installed by a qualified installer. The sheet metal top and sides can be easily removed to reduce the chance of dents or scratches on the painted surfaces. To remove the sheet metal, first lift off the top section. Now, the sides can be removed by lifting up and out away from the furnace. Caution: This furnace must not be installed closer than 24 inches at the sides and 30 inches from the rear to combustible materials. - Page 5 Installation Venting Guidelines.

Page 6: Mounting Blower & Filter Box
Installation Mounting The Blower And Filter Box Position the filter box between the brackets on the rear of the furnace, with the bottom of the box resting on the flange at the bottom of the furnace. Insert the mounting clips into the bracket slots to secure the filter box. (see Figure 2) Next, install the blower brackets onto the blower being sure to install the rubber feet into the brackets. All hardware, brackets, etc. for the blower, will be found in the carton with the blower. 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.

Page 7: Wiring
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 responsibility 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 accommodate 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. -

KEEP CHILDREN AwAY - MAY CAUSE SERIOUS BURNS. Ashes - Ashes should never be allowed to accumulate in the ash pit so that they in any way impede the flow of com b ustion CAUTION air to the fire. Excess ash ac c umulation can cause the fire to go out and also can cause severe damage to the grates because of the absence of a cooling flow of air beneath them. -
Page 11: Maintenance
Maintenance The spiral chamber is basically self-cleaning. However, if there is a draft problem and you have been burning wood for a long time with little heat demand, the spiral chamber may need cleaning. Soft coal will also require more frequent cleaning. To clean, remove stovepipe and scrape the creosote from the front and top of the chamber and remove. The rear of the chamber will not accumu l ate creosote. NOTE: 1/8” to 1/4” of creosote in the spiral chamber is normal. Creosote can be burned off by burning coal for a few days. Firebricks may become cracked during the course of normal operation. A cracked brick that is still in place is still doing its job and need not be re p laced immediately. If a brick is broken and has fallen out of place, it should be replaced immediately. The firebrick used in the Harman furnaces are inexpensive and easy to replace. The blower manufacturer recom m ends the blower motor to be oiled once a year with 10 to 20 drops of light weight oil [check instructions packed in blower box). 3-90-70744R13_11/13... -
