Harman Stove Company owner manual P43 Automatic IGNITION/OPERATION, Room Temperature Mode

P43 AUTOMATIC IGNITION/OPERATION

The P43 is a fully automatic stove that features two operating modes; Stove Temperature Mode and Room Temperature Mode. In Stove Temperature Mode, you select a burn rate and the stove will remain at the same burn rate regardless of the room temperature.

In the Room Temperature Mode the stove constantly monitors the temperature in the room and adjusts the size of the fire and the heat output of the stove so that the room is kept at a constant temperature. Room mode, in the AUTO position, has the added advantage of turning the stove off if no heat is required and turning the stove on again when the room temperature drops below your desired room temperature.

Room Temperature Mode

Most consumers use the stove in the Room Temperature Mode because it is the easiest and most efficient method of keeping the room at a given temperature. In the Room Temperature Mode, the Room Sensing Probe constantly monitors room temperature. As the weather changes outside and your home needs varying amounts of heat to be at a desired temperature, the stove will automatically increase fire size and heat output so that a constant even temperature is maintained. If the weather warms up and no heat is required, the stove will gradually shut down. When the house cools down, the stove will automatically bring the room temperature to the precise temperature you desire.

In the Room Temperature Mode you can select either Auto or Manual modes for the igniter, using the igniter toggle switch. When the toggle switch is in the Auto position, the igniter, located inside the burn pot, is ready to automatically light the fire when required. When the toggle switch set to the Manual position the stove can be lit manually with either a gel or a wax type fire starter. (see lighting instructions on page 19.) With the igniter toggle switch set in the Manual position the stove will automatically adjust heat output, but the stove will not automatically shut down if no heat is required. Instead it will go to its lowest setting and remain there. The Manual position on the igniter toggle switch lets you light the stove manually, should the igniter fail for any reason. Secondly if you are using the Harman battery back up system, the Manual setting will prevent the stove from turning off and on during a power failure, which would drain the back up battery, and possibly cause damage to the back-up or the stove.

In the Room Temperature Mode, the distribution blower speed can be increased or decreased by adjusting the Room Temp/Off/Stove Temp dial between L and H. As output of the stove increases, the speed of the blower will increase automatically to insure that more heat is transferred out into the room. The distribution blower will shut off as the room reaches the set temperature, this will prevent overheating of the room.

Room Temperature Mode

Room Temperature Mode: This setting, see above, will produce a room temperature of 70 degrees with the distribution blower at medium speed.

Circuit Board Dipswitches: On the face of the circuit board, there is a series of 8 switches. These "ON-OFF" switches are used to set the timings and temperatures for the different models of stove. For a P43, the switches numbered 5 and 8 should be on, with the rest of them off. Never adjust these switches yourself, as serious issues could develop. Also know that if there is a need to replace an ESP probe,a switch change may also be

needed. It is strongly recommended to have a trained service representative make any repairs to the appliance.
