P43 trouble-Shooting

cleaning burn Pot

Whenever your stove is not burning, take the op-

portunity  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 Temp Dial to number 1 approximately 30 

minutes before removing ashes. This will result in a 

cooler stove and ash pan.

Maximum Feed Adjuster settings are not needed 

in  most  cases.  Operating  in  the  normal  range  (#4) 

is recommended when maximum heat output is not 

required. The  ESP  control  prevents  the  stove  from 

being over-fired.

Keep the stove free of dust and dirt.

helpful hints

Fuel

  

StOve dOeS nOt Feed

1. No fuel in hopper.

2. Firebox draft may be too low for sensing switch in 

feeder circuit to operate. 

check for closed doors

loose or missing gasket on doors or hopper lid.

3. Hopper lid must contact the lid position switch.

4. Feed motor will not run until the ESP control 

senses a certain temperature. Maybe you did not 

put enough fuel or starting gel in the burn pot before 

manually lighting the fire.

5. Restriction in the hopper or feeder. Remove all 

fuel and examine. Clear the obstruction.

6. Feed motor has failed.

PartiallY burned PelletS

1. Feed rate too high.

2. Poor air to fuel mixture. (Check burn pot clean-

out cover and air intake).

3. Burn pot or heat exchanger tubes may need  to 

be cleaned.

4. Combination of all the above.

5. 

#6 status blink

: A 6 blink control board status 

indication is caused by poor or incomplete combus-

tion. The circuit board has the ability to track the 

combustion through feed settings and ESP tem-

peratures. When the control board has calculated 

poor or incomplete combustion, it will shut down 

the unit as a safety feature. (Poor or incomplete 

combustion is a contributor of creosote which may 

cause a chimney fire)

A  6  blink  status  may  be  caused  by  several 

things:

1. Blocked or partially blocked flue.

2. Blocked or partially blocked inlet air.

  a. Backdraft damper on the inlet pipe may be 

stuck closed.

  b. If outside air is installed, the inlet cover may 

be blocked.

3. The air chamber under the burnpot may be filled 

with fines and small bits of ash.

4. The holes in the burnpot may be getting filled 

with ash or carbon buildup.

5.  Combustion  blower  fan  blades  may  need 

cleaned.

6. Fuel restrictions as noted above.

SMOKe SMell

Seal the vent pipe joints and connection to stove 

with silicone. The exhaust vent is the only part of 

the system that is under positive pressure.

Fire haS gOne Out- check for status light.

1. No fuel in hopper.

2. Draft is too low, blocked flue.

3. Something is restricting fuel flow.

4. Hopper lid not closed properly.

5. Feed motor or combustion blower has failed.

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 P43 is capable of burning all 3 categories 

of pellets due to a patented feeder and burn pot sys-

tem.

It  should  be  noted,  however,  that  higher  ash 

content, and when mixing with corn, will require more 

frequent ash removal, scraping of the burn pot, and 

may provide less BTU's per pound. Normally, standard 

and high ash pellets cost less than premium pellets and 

can be cost effective when burned in the P43.

The moisture content of pellets must not exceed 

8%, and corn 15%. Higher moisture will rob BTU's and 

may not burn properly.

 Fuel should 

not 

be stored within the stove installa-

tion clearances or within the space required for charg-

ing and ash removal. See Page 7.
