    Here is the wiring diagram as related to the t-stat connections just in case you didn't have it.

    And here's the rest of it. Couldn't get it all in one pic and still have it easy to read.

    Here is a pic of mine on low. Can't see the flame, just the glow and sparks.

    I timed it and the auger motor runs for 2 seconds on, 8 seconds off when on low. Hard to hear the auger motor when it's on high with the convection blower running.

    T-stat mode and heat at#1. Jumper on R & W. Will try to buy a T-stat tomorrow.

    Flame has the same look as mine on #1. I will try to check timing on auger on #1 later. Cold snap at the moment. The way I check the timing on the auger is with a Kill-a-watt meter and watching the watts go up/down. Picking up 2 bags of grain tomorrow to test for a possible order this summer.

    The furnace should not need a jumper between the blocks. That is why it has manual mode and tstat mode.

    Remove the jumper and take it up to 5 in manual.

    I'm still running LP to use it up. It has been the nice the last 2 days not having to fill the wood eater and pellet furnace. :D

    What is this jumper you speak of?

    Just a stray wire getting ready to add a T-stat. Wires touching to act like a fictional T-stat. Part of my troubleshooting.

    From Matt? If my tstat is not hooked up, then I am to have no wires or jumper connected.

    I could undo the wires touching and leave it stray until I hook up a T-stat. It made no difference earlier on when there was no wires, same symptoms. I will be checking auger intervals soon on different heat levels.

    I did the timing on the auger feed on fuel type(#3 setting, corn/premium pellets, medium feed/normal dump):
    I did a timing check on auger on/off for different heat levels; intervals in seconds(approx.)
    on--------off-------setting
    5----------5----------5
    5----------6----------4
    4----------7----------3
    3----------9----------2
    2----------9----------1
    I changed my fuel type to #5(fast feed/normal dump and it's On for 6 sec./Off for 5 sec./ heat#5 and will be monitoring the results. I was told fines can hold back feeding pellets so I make sure the bottom of bags are not dumped into the hopper. I never had a top feed auger system so this is all new to me.

    Sounds like it is working as it should..

    Now you need more air supply to burn the pellets properly.

    There is a few things you can do here. You can buy some of the upgrades to increase airflow through the burnpot? Or you can modify a few components to induce more air under the pellets in the pot.

    The main one, is the Burn pot of the Fahrenheit. The back (pusher) and the front (door) have 80% of the holes above where the air is needed. For corn, this may be slightly beneficial. But for pellets, all the air should come from underneath (majority anyway).

    I can take some pics and PM you what I did to my pot. 343amc also did this to his and he has an early version pot, and had the same good results.

    Also, the ash pan gasket and latches Suck. I used the same type of gasket material, but just put it over the original. So my gasket is twice the thickness, and now a dollar bill doesn't slide out.

    Check door gasket, and adjust latch as necessary.

    Few other things I am forgetting.

    I now have a larger combustion blower, larger impeller, high flow Exhaust Manifold, high flow Sail Switch, and I have installed gaskets to the burn pot receptacle, so that the pot has a snug fit and that it has very few leaks.

    The flame height is much better but am I wasting pellets? Got no choice to heat the house in this cold snap. Dex, you can PM me with the modifications. I will tidy up the duct when time and heat requirement subsides some.

    Just seen this..

    I will try and do it tomorrow evening. I have to take my son to his Klondike camp out for Scouts. But will take pics of the pot after I return home.

    Here is my furnace on level 3.


    Fahrenheit Endurance Bio-Mass Furnace:

    This was 2 years ago. It's even more vibrant after the new blower motor and impeller this year. The impeller is like $20 and Don2222 sells them. It's a big impeller, but flows much more air. I also added a higher amp motor. But the impeller alone would make a big difference.

    The stock impeller is on the left. A replacement impeller out of my old Quadrafire is in the middle, and the new impeller is on the right (on the orig motor/I replaced the motor soon after).

    I remember the write up on the new big *ss fan. Gotta be a lot more air through the furnace. I can imagine my rye seeds getting suck right through the fire chamber without catching fire & igniting out the vent like a oil rig:bug: A little displacement of fire from the pot they say:D upload_2015-1-15_23-22-30.jpeg

    Looking at the flame this morning and it was lazy. Further inspection, I was able to see some unburned pellets in the burn pot, mmm! Ok, burn pot filling up I say to myself. I opened the hopper to trigger the stop auger function and let the fire die down some. I poke inside the pot and there was something in there, after the 90 sec. the furnace shut down on loss of draft. So I do the relight sequence and it goes through the burn pot ash removal procedure. Getting ready to relight, I decide to recheck the burn pot and what do we have here. Clinkers that did not fall out the burn pot? from the rye grain trial? cold pellets from the outside garage? So a relight in progress and the flame is a lot more active. Lesson learned today, poke in burn pot before relighting and lazy flame symptom.
