I'm searching for a Manual:
I purchased a fixer-upper Pellefier pellet stove, just as a shop stove.

It was made by Collins Bio-Energy in Tacoma WA in mid 80's. Not sure who finally ended up with this line, but I've search to no avail on finding a manual for this stove.

The controller board is # 121386C by KWM Electronics Corp in Utah. Not sure about that company either. They were a custom Printed Circuit Board Mfg.

Stove had no auger motor, and I fixed that, but I may have a slower RPM than the controller 'thinks. My auger is at 1.6 RPM, and just wasn't staying on long enough (7 seconds). This controller has a couple of switches on back that are for "FEED TIME and CYCLE TIME". I first started running this with a jumper for the T-Stat. Switching the 2 switches (like 'dip switches) made NO differences at all. I then discovered that changing the potentiometer for 'Auger Feed' from 50k ohm's to 500k ohm's gave me a much longer auger run time (10 to 30 seconds)! Also, I finally connected a thermostat and found that the 'dip switches DO have some effect when T-stat kicks stove into Low Mode. This stove has no Low Temp limit switch, and so, if the fire dies, it has no clue. Hence, the potential for feeding pellets into no fire!... I may try to add this feature, so if flame or power dies, controller stays off. Of course it has no auto-lite feature either. My Harmon Pellet Furnace in my basement has all the bells and whistles needed, and I really like this one, so I'd like to get my shop stove a bit more modern.

Serial No.: 134
Model: Pellefier (not Pellefier!)
Patent No.: 4,565,184

I'd be grateful for any help on a manual for the Pellefier or KWM Controller board.
 
I have a thought that the controller is the same as my old Jamestown, but I don't have access to the stove or the manual right now. Maybe someone out there can check theirs.
 
that design was sold to Martin Ind.
and turned into the Martin verntury pellet stove
I believe they ran a 4 RPM auger motor
 
Thanks for the info guys!

So if the original auger gearbox was 4 RPM, that explains why my 1.6 RPM was not feeding enough!

I'm attaching pics in case it jogs someones memory about setting this type of "stoker control"
The two dip switches Cycle Time (min) 32/8/16 & Feed Time (min) 2/4/1 are shown at the top of the board.

I'd guess the 32/8/16 and 2/4/1 are in seconds?
My switch to a 500k ohm pot for auger feed is shown at top left of controller pic. It was much larger than the original, so I hardwired it. This gave me that extra feed time I needed.

BTW The lesson ( in Announcements) on "How to prepare pictures..." helped a bunch I really like that Picasa program!
Happy New Years to all :coolsmile:

Yep that looks like the same board used on the Martin Venturi FS 1, 2 and 3
but the Martin stoves did not look like that.

you want to be sure you have the Stat wires together if you are not using a stat or the stove will only run in Keep fire mode and the room air blower will run on low.
 
I'm new to this site. I have a friend that has a 1984 Pellefier pellet stove mod. FS-1 serno. 87080701 that has a problem. I tried to light it but noticed there was no or little smoke going out exhaust even though the exhaust motor was turning. Would like to take off the exhaust fan motor BUT sure would like a manual first. Is there a online manual or schematic? . Also there seems to be no incoming air blowing on to the fire.
