I HAVE A KEYSTOKER 120 AND I SEEM TO USING A FAIR AMOUNT OF COAL, MY CONVECTION FAN RUNS QUITE A BIT I KNOW THAT I HAVE TO MOVE IT CLOSER TO MY HEAT EXCHANGER AND I NEED TO DO SOME FINE TUNING WITH MY PLENUM BUT I WANT TO KNOW THE RELATIONSHIP WITH THE AIR INLET ON THE COMBUSTION FAN AND THE COAL FEED ADJUSTER I AM ONLY RUNNING 5 PINS IN MY TIMER(PER CYCLE) AND I HAVE MY FAN LIMIT CONTROL SWITCH SET TO 100-160 ANY IDEAS WILL BE GREATLY APPRECIATED

Ours is a keystoker 90. What is a fair amount? on really cold nights, ours will burn up 30-50#'s depending.

Our Timer has 5 pins every 10 mins, that is for the IDLE/pilot mode when the Thermostat doesn't need satisfied. (each pin = 15 secs so, 5 x 15 = 75 seconds) It takes the feeder/stoker about that amount of time for 1 cycle back and forth. The thermostat basically overrides the pin by keeping the feeder running and "stoking" the fire until it heats up enough to satisfy the thermostat.

There should be a FEED adjustment on the stoker part, screw with a tab on it under the coal bin. Thread it in by hand (closkwise) until snug and Should be 2 turns out counterclockwise. This adjusts the feed rate. Out more decreases the feed rate, but not too much. I have had ours out 3 - 3-1/2 turns and it is barely burning, less than 1 inch wide.
Depending on your placement of your thermostat, the setting is too high and is is always having to feed it to maintain a certain temp, ours is about 10-12 feet from the stove.

I also put a Digital Thermostat with 4 programmable settings for different times of the day and that seems to help too! Cooler at night and during the day when we are working.

Our Convection fan is set 110 - 160 Deg. so that is about right. but cycles on/off depending on the temp.

I wouldn't mess with air inlet, that is usually factory set.

Does that help?

Questions, let me know. I am learning too! (First year)

Saving Coal!!

I've asked various times through this forum to see if a heat exchanger on the stove pipe is a good idea to improve efficiency. It seems like when any stoker runs faster the stove pipe heats up and more heat goes outside, not inside where you want it. The heat reclaimer should minimize the temperature increase of your stove pipe at higher settings and put more heat in your house where you want it. Does anyone else know if a heat reclaimer is a good idea to increase efficiency, particularly when its colder outside and there shouldn't be issues with low draft?
