    I did my own timing on auger feed for the different heat levels and they look similar, it was part of my low flame troubleshooting start-up issues I was encountering. Good to know more in details of the trim adjustment. After adjusting the trim, #5 Heat Level is extended by 1.3 seconds so to make it now 7.8 seconds ON/ 2.2 seconds OFF or it only works with the #1 Heat Level setting?

    That was my thought as well, that adjusting the trim adds time to all heat settings. However, after asking for clarification from Matt, he informed me that the trim setting only affects the feed rate on heat setting 1.

    Not sure why, I'd really like to be able to adjust the feed rates on all heat settings. The burn rates are so different from pellet type to pellet type that it would be a huge bonus to have that flexibility.

    Auger and draft trims are to help fine tune the 1st heat level. The exhaust blower on this furnace runs at the same speed, regardless of the heat level. So you get the same amount of air on levels 2-5. More fuel means more air.

    So you set your air damper to get a good burn on your high heat level. Then you adjust level 1 with the trims. So that when the thermostat is satisfied, you get a good burn on level 1. To much air on level 1 will burn the pellets out to soon.

    So it's a balancing act on getting a good burn on the heat level that the furnace goes to when calling for heat and also when the call for heat is not needed and it reverts back to pilot/Maintenance burn.

    It makes sense in theory. I just wish I could adjust the feed rate so I could keep enough pellets in the burn pot on the #5 setting. But I'm hoping once I get the air leaks fixed I won't need to have to put as much fuel into the burn pot. Time will tell I guess.

    The ash pan is a spot that leaks bad because of the latches. I doubled up on the flat gasket for the ask pan. I installed another flat gasket, directly over the existing gasket. When I replace it, I may go with a small round gasket (3/8") to get a better "squish" on the pan.

    I think I'm actually ok on the ash pan. I did a flame check around the ash pan and saw no signs of leakage. However, I agree with you. I did flat tape and when I redo it in the future, I'm going to use a round gasket.

    I was going to say the same thing, I'v seen the cover but didn't know there was a secret door behind it lol. I wish the manual was an actual manual that helped, not a quick start up guide.
    Thanks Dex, another tip learned.

    It wasn't as bad in there as I thought it would be, but it wasn't clean either.

    Check that off the list.

    That isn't bad, but any and all ash on the top and sides of the firebox will prohibit better exchange from the air blowing around the firebox.

    I'm always learning new stuff myself. That's the best part of the forum. :)

    Ban83 There's a good chance I'll be in the vicinity next week, PM me if we could meet up. It will likely be during the day or later part of the day.

    UPDATE!

    Got my 50F back together. The hopper leak appears to be fixed. The gasket between the top panel and hopper wasn't sealing properly. The addition of the white foam to (see earlier post) to the top of the hopper seems to have addressed the leak. I never had to do any silicone work.

    I ran a test fire tonight, the flame seems better but will get some video to post for review and opinion by the other 50F guys out there. It still seems to be doing some weird stuff. The flame tends to go to the side instead of straight up out of the burn pot. I'm thinking I must have some blockages still behind the back panel. I'll check it out tomorrow night hopefully.

    Mine always veers to the left. All the air comes in from the right of the pot and pushes hard to the left. The only Fahrenheit furnaces that I seen burn straight up, are the earlier pot models.

    Ah ok. Well this is good to hear. I guess it makes sense Dex, as you said the air does come from the right side of the pot and if my thoughts are right (and you may have mentioned in an old post) the channel in the back panel is larger on the left, so this would draw more air down the left, adding to the leaned over flame.

    I'll double check all the exhaust cavities again tonight to make sure I'm free of obstructions though. I should be good as I was pretty thorough in cleaning, but better to double check. I would have done it last night but was getting late and wanted to get a test fire in to see if the hopper leak was fixed.

    Another thing I'm having issues with is the igniter. I was talking with Matt when asking for a quote and I guess the type of igniter they use is good or bad, yet I'm having slow ignition. Seems to be ever since I moded the burn pot yet I don't know what I did that would affect the ignition, unless the extra air going through now is creating a cooling effect and slowing the ignition. In the recent tests I don't even wait for it to light, I end up starting the fire with a torch. You guys have any thoughts?

    By the way, new igniter from Fahrenheit is $263 US, so that means us Canadian folks will have to pay for shipping plus another 30ish %. :headbang::hair:

    Yeah it's getting there, not sure how good of humor I'd have been in if this last round of worked hadn't addressed the hopper leak. I may have had a posting on here for a furnace for sale!!!

    The flame on mine tends to lean to the right when it's cranking (when looking at the fire). When it's on 1 or 2, all there is to see are sparks coming from the burn pot.

    My igniter ran out the other day, but I picked up another for about 9 bucks. Guess that's one benefit of the old model.
