Harman Stove Company P61-2 manual Trouble-Shooting, Cleaning Burn Pot

Trouble-Shooting

FEEDER DOES NOT FEED

1.No pellets in hopper.

2.Feed motor will not run until ESP senses 165 deg. F. Maybe you did not put enough pellets in the burn pot before lighting the fire.

3.Feed motor has failed.

4.Something is restricting flow in the hopper or causing the slide plate to stick.

5.Firebox draft may be too low for low draft pressure switch in feeder circuit to operate. Check for closed doors, loose or missing gas- ket on doors or hopper lid, faulty pressure switch.

PARTIALLY BURNED PELLETS

1.Feed rate too high.

2.Draft too low. (Check burn pot clean- out slide and door gasket).

3.Burn pot or heat exchanger tubes may need to be cleaned.

4.Combination of all the above.

SMOKE SMELL

Seal the vent pipe joints and connection to stove with silicone.

FIRE HAS GONE OUT

1.No pellets in hopper.

2.Feed rate too low.

3.Something is restricting fuel flow.

4.Feed motor or draft motor has failed.

5.Power failure or blown fuse.

SMOKE IS VISIBLE COMING OUT OF VENT

1.Air-fuel ratio is too rich.

A.Feed rate too high.

B.Draft too low caused by a gasket leak.

LOW HEAT OUTPUT

1.Feed rate too low

2.Draft too low because of gasket leak.

3.Poor quality or damp pellets

4.Combination of 1. and 2.

Helpful Hints

Cleaning Burn Pot

Whenever your stove is not burning, take the opportunity to scrape the burn pot to remove carbon buildup. A vacuum cleaner is handy to remove the residue. Be sure the stove is cold if you use a vacuum.

Carbon buildup can be scraped loose with the fire burning using the special tool provided with your stove. Scrape the floor and sides of the burn pot. The carbon will be pushed out by the incoming fuel. Always wear gloves to do this.

Removing Ashes

Turn the Stove Temp Dial to number 1 approxi- mately 30 minutes before removing ashes. This will result in a cooler stove and ash pan.

Maximum Turbo settings are not needed in most cases. Operating in the normal range is rec- ommended when maximum heat output is not re- quired. The ESP probe prevents the stove from be- ing over-fired.

Keep the stove free of dust and dirt.

Fuel

Pellet fuels are put into 3 categories in terms of ash content. Premium at 1% or less, Standard at 3% or less and all others at 3% or more.

The P61 is capable of burning all 3 categories of pellets due to a patented feeder and burn pot system.

It should be noted, however, that higher ash content will require more frequent ash removal and may provide less BTU's per lb. Normally, standard and high ash pellets cost less than premium pellets and can be cost effective when burned in the P61.

The moisture content must not exceed 8%. Higher moisture will rob BTU's and may not burn properly.
