Fahrenheit Technologies Endurance 50F Information

just for fun

 

ok...I'll give that a go...

 

I hope this works...

 

Dexter - I appreciate your comments as you are the pioneer and the model I followed for my mods. I'm curious about your last post and would like to better understand what you think the right balance might be? I'm really curious because I see other pellet stoves burning much the same way as I was finally able to get mine to burn. No doubt the exhaust is much hotter, but the house heats up much faster as well. I mean, pellet stoves require double walled vent pipe for a reason...right?

I wish I had the time/patience to make a mod then test and measure improvement...but unfortunately that didn't happen. I did a number of "improvements" this time around so not sure what gave me the best benefit. I know I had hopper leaks as I had the "V" thing was going on...so I resealed everything and removed the hopper extension as well. I honestly think the incoming air being split 50/50 (50 to pot, 50 to door) in the frame is a curious design. It was a PITA to undo that split (although I didn't have my plasma cutter up & running so it might be easier with that) as it's tight in there, but I really don't think (well...I know) you need all that air flowing around the door as my door is flowing no air and the door is only lightly (very lightly) seated with no gaskets.

Well - so far so good, been running a couple days & my 2,700sf house heats up fast!

 

I think the air around the door helps it keep cool to prevent overheating but I can be wrong. Do I need to shave the assembly to use a rope gasket? If I don't, I'll put some before I use it for the larger heating season.

 

Well...raising the pot an 1/8th shouldn't do much...you'd just need to ensure the re-light plate arm clears the slightly raised pusher (if not that area can be ground down to allow clearance). That might also extend pot life as the main pot failure area (igniter area) will have a bit more clearance from the igniter as well.

 

Dex - I appreciate the advice...is there a ratio I should be trying to achieve? That burn was at maybe 30% airflow and I didn't even clean my exhaust pipe from last year...it was also 50 degrees and pretty high humidity, if I recall.

What's the best way to measure those temps? I have an IR reader, but guessing a probe may be better???

And please...don't ever be jealous of me...like I said, I'd never even dream of attempting any of this if you hadn't paved the way...and I still owe you a better pot!

So...it burns really well...and I didn't even do the exhaust manifold mod...I guess that leads me to believe that the real issue with the 50F is not outgoing or incoming volume capabilities, but rather the efficiency of utilizing what it already has. I did upgrade the sail door and I'm running Don's exhaust motor/impeller combo...so I'm moving more air, but even with those mods my OEM pot/frame setup came nowhere close to burning the way it does now. I think the real issue is that frame 50/50 split and sealing off air gaps...I mean having a thicker pot should have no impact on burn performance but rather just an improvement on service life.

Knowing what I think I know, if I had to do it all over again I'd probably just:
1) Replace just the V section of the pot with 1/4" SS (I'm going to try that on a butchered pot I have laying around to see if feasible)
2) Modify the frame:
a. open up the 50/50 split
b. block off the door flap ports
c. use 1/4" SS modified door
d. modify pusher arm to work with modified door
3) Use a 1/4" SS re-light plate

I'd be curious how the above would run (assuming good seals on the doors and hopper are in place)...

 

I'll have to look into a probe and see what's it reading...unfortunately, it doesn't stay at it's max burn for long...but then again it's been a mild fall. Hard to tell from my vid angle but the exchanger plates were taking a blame beating...so much that I'm going to have to keep an eye on them as they do warp...maybe SS for them in the future as well...

 

Hello, I'm new to forums,so please forgive me if I'm not in the right place.Growing up I've always had wood heat,we moved to a new house last march and I installed a Fahrenheit Endurance for ease,End of March ,April,and part of May she worked well went though a ton of pellets,Gave her a cleaning top to bottom, unplugged it for the summer,Went to start it up and the end of October,No dice, Wouldn't even power up.Got a new Board from the dealer,7 days later, and it came to life, but not the same.
In one week,I only used 10 bags.But it filled the ash pan,Black soot all over out side,at one point it got so hot i could hardly touch the front door!I called the dealer asking questions,So i cleaned everything again,stove ,exhaust,check fresh air inlet, hopper.I had a lot of fines in the hopper so a vacuumed them out and half azz sifted the pellet before loading hopper.The dealer also told me to open the air inlet wide open.... its be running perfect now for a day anyone else run into this ?Im building a vac pellet sifter this afternoon so no more fine go though my stove. Thoughts?

 

Welcome to FHC Irish-1
You've come to right place for help with your new furnace. We got to thread lightly with issues because of warranty, we do not want to void that
Can you post pics of your set-up including vent. Self install or dealer?

 

Thanks Fellas ! Ivanhoe,Self install.Here are a couple pics

 

I see a OAK
Nice clean install
Is basement damp?
What's the vent consist of, elbows and lengths? And outside make up?
The length of OAK?
Serial # for furnace version?
Lots of questions, just trying to get the feel of the setup for troubleshooting

 

OAK= Outside Air K?? Im # 3592. The Exhaust vent is 3" to 4" right at the stove outlet, 4" Tee then a 36" length, a 90,then a 48" though the basment wall and has a fancy ss cap on the end. pipe is 16" off the ground. The Outside air is 2" flex and probably 10' in length. Thank you for the kind remarks on the install. Information is key in trouble shooting! Basement is Dry,I also run a dehumidifier,Ive got seven tons pro pellets stored there too, with spacing around all pallets and a articulating fan moving air
around them.

 

Outside Air Kit
If you can post a video of the flame in action preferably on high would be helpful. What color is the ash on the walls of the fire chamber? Where are you at on the damper for intake air?
