  • Page 19: Checking Power Supply

    Checking Power Supply Before plugging into any outlet, be sure to test it. Wall Outlet Proper polarity and correct voltage are of the utmost importance. To check polarity; There are plug in testers available that simply plug in and reveal a series of lights to tell you if the polarity is correct.
  • Page 20 Draft Testing All Harman pellet units have a test port on them for checking the draft. There is a draft meter kit available from Harman Stove Company, which also includes a digital multi-meter. This draft meter includes a bolt-type fitting to attach the meter to the stove.

  • Page 21: Draft Test Procedure

    Draft Test Procedure For Units with “test” mode • Remove draft test plug bolt. (9/16 wrench) • Remove hose from draft meter • With meter standing vertical, adjust needle to zero • Hook up the test hose to the “low” port on the meter this is the port for measuring negative pressure •...

  • Page 26 Auto-Ignition Cycle The Ignition cycle is around a 10 minute cycle. At the beginning, the combustion blower, igniter, and feed motor all come on. After 3 to 5 minutes, the feed motor stops. Now the burn pot is loaded with fuel. The heated air from the igniter passes through the bottom row of holes, and heats the pellets to their ignition point.
  • Page 27 The ESP Control Once the fire is burning, the ESP probe, located in the exhaust, monitors the temperature and reports them to the circuit board. The first desired temperature is 135 deg.F at 135 the feed motor is allowed to run. Next, when the temperature reaches 160 deg.F the distribution blower will begin operating.

  • Page 28: The Combustion Process

    The Combustion Process Harman pellet burners operate with a negative pressure firebox, and a positive pressure vent system. The combustion blower is positioned after and below the burn pot. It is blowing air out through the exhaust. The air that is being used for combustion comes through the air intake on the back of the stove.

  • Page 29: Shutdown Procedure

    Shut-Down Procedure When you turn the stove to “Off”, there is a protocol programmed into the circuit board which will not allow the combustion blower to just stop. Upon turning the stove to off, the only change is that the feed motor will only run for about 7 seconds per minute.

  • Page 43 The ESP Probe The ESP Probe is a thermister, it reports the exhaust temperature to the circuit board in a resistance reading. The resistance changes with every thousandth of a degree F. The wires on most probes are black, however, you could also see them in yellow or white.
  • Page 44 Feeder Position Switch Used on the Invincible Series, and older P-61’s. Ensures that the slide plate is closing when the pusher arm returns. If the switch doesn’t sense a full closure for a period of 30 minutes, it will cause the status light to blink “2 blinks”.
  • Page 45 Draft Differential Switch Diaphragm switch which is used to monitor the negative draft pressure in the firebox. The older blue switch can be used as a normally open (NO) or normally closed (NC) switch. In the Harman Pellet stoves, it is used as normally open. Notice the wire terminals are labeled NO, and NC The hose ports correspond to the wiring positions.
  • Page 46 The PF-100 uses a 6 r.p.m. motor. The Advance and Accentra models use a clockwise directional feed motor. This is identified by either two white leads, on older units or black and red leads on the newer ones. It is also a 4 r.p.m.
  • Page 47 Igniter Positioned in the bottom of the burn pot Always air flowing over it (prevents burnout) Easy access removal for cleaning Important: when reinstalling an igniter, be sure the wires, within the burn pot, are pulled out of the rear of the feeder body as far as they can be to prevent melting.

  • Page 54 Automatic Circuit Board Dipswitches DDM Test Port All Harman automatic pellet stoves now use the same circuit board. There is a series of switches on the board, (dipswitches), that are set differently depending on the stove model it is installed onto. Some switches allow for changing things such as ignition feed cycle, or igniter timing.
