Updated Stainless Steel Burnpot Weldment Kit for Harman PF100, PB105 1-10-73560-AMP

This updated burnpot weldment kit for the PF100 and PB105 pellet furnaces and boilers has been redesigned with stronger metal and expansion lines in the steel to allow for proper heat expansion. Earlier models will have burnpots that can "bubble" on the fire surface just above the igniter.

When using on units with pressure ignition, an igniter bracket is not necessary.

When removing the old burnpot take special care not to break the ceramic insert. 

NOTE: PF100 & PB105 early models with cartridge igniter will need a new stainless steel bracket. Due to the igniter holes in this new burnpot being in a slightly different location than the older burnpots the unit starts the charge cycle (the length of time the feeder pushes pellets into the burnpot each time the unit tries to light) will need to be changed. See Dipswitch Chart Below (dipswitch 1, 2, 3). Note: When using cartridge ignition; understand this, more pellets over the igniter holes are NOT BETTER than fewer pellets over the igniter holes. The proper amount will only cover the second row of holes from the bottom. Too much fuel during an ignition cycle takes longer to light, makes more smoke, and has a greater chance of having a post ignition violent ignition (this is when you hear a loud pop or thud when the first flame becomes visible). Due to the fact that there were different auger motors and pusher arms used over the years, we cannot give you exact dipswitch settings and will require some observation and adjustments to be set by the installer.

To replace the burnpot:

1. Unplug your stove
2. The igniter is inside if the burnpot. From the rear of the stove, find the yellow and light blue colored wires that are coiled up and secured to the wiring harness. cut the zip ties that hold this collection of wire together. when the burn pot is removed, this is the length of wire that will pass through the stove body as the burn pot is pulled out. If the wires are not free to travel, the burnpot will only move about 4 inches.
3. Locate and remove the 4 1/2" nuts that secure the burnpot to the feeder weldment threaded rods. You may need a universal joint at the end of your socket wrench to make the connection at the top nuts.
4. Pull the burnpot assembly forward until the yellow and light blue wires are visible, then disconnect the igniter wires. Now the burn pot is free to come out of the stove
5. Remove the two 5/16" screws that hold the igniter in to the burnpot and then remove the igniter assembly
6. If you are replacing your igniter, do this now while the burnpot is free from the stove.
7. Make sure to run the wires for the igniter through the right-side opening at the rear of the burn pot
8. Replace your burnpot gasket, make sure your yellow and light blue wires are passing through the hole and through the center of the gasket.
9. Connect your igniter wires and pull the yellow and light blue wires from the back of the stove so that the disconnects pass backward through the opening. Try to take out as much slack in the igniter wires as possible so that they aren't pinch by the burnpot when it is fit into place. Note: for this part of the job, having another person around to pull the wires as you fit the burnpot in stove is key.
10. Replace your new burn pot over the threaded rods and tighten down all 4 1/2" hex nuts. You will feel the new gasket compress as you tighten the burnpot down, this is normal. DO NOT PINCH THE IGNITER WIRES WHEN DOING THIS PART
11. Replace the clean out cover and secure your wires in the rear of the stove.

The burnpot is a central part of the Harman Pro Pellet Feed System. Generally, the burn pot weldment doesn't need to be replaced and should last the life of your stove.

Many folks will replace the burnpot if their stove is having problems igniting. In general, slow or missed ignitions are a problem to do with an air leak within the stove and not the burnpot itself. Obviously, if your burn pot has a big hole worn in it or there is a bubble on the burn surface where the metal has changed shape, those are examples that would require a new burnpot.

If you are having delayed ignitions and can verify that they igniter is getting hot;

1. Tighten the four 1/2" nuts that secure the burnpot.
2. Replace your door gasket and the ash pan gasket if you have separate doors
3. 3. Look at your door handle to make sure the comp
