So you think i should put it back together with the original k8 relay, since this ebay version is blowing the breaker box?

I don’t know of any reason the heat side would cause a breaker to trip. The ignitor runs in fan, fuel pump runs in fan, only difference on heat is valve opens for fuel.

Did you cut the p2 plug off to install the new k8?

I had time to install the ‘new’ k8 on a spare heater, it worked as designed so i am at a loss why it didn’t work for yours unless there are other problems. Verify that the spade connectors are not touching, i had issues with them wanting to twist and touch while tightening.

I have the M-82. Last year I had the burner unit backfire and blew out the photo eye and the flapper valves. I have a new burner unit and will get to work on it soon.
Other than that worked well, and have the same issues everyone else has.
Any thoughts on the M-82-83 vs the DRASH? I think the DRASH would be handy since it can provide some MEP as well as HVAC. I haven't really used a DRASH before.

Hello. New to the world of military duct heaters. Just picked up a h82 with 5 hours according to the meter. Seems to work fine after cleaning out the rats nest inside of it. Kinda noisy. Like a whining. Was wondering how to get the maximum heat out of it. All settings and everything have had it running for about 2 hours now

While we are on this topic, does anyone know the specs for the pilot light bulb, mine is broken, is it 120VAC?

Both of my H-83's died due to a broken piece of plastic! The pump coupling to the motor finally gave way on both units. I too bought junk from GL with less than 2 hours on each one 2 years ago. Then I found out the meters were disconnected per procedure. Nice! Does anyone know where to find new pumps or couplers? Looks like they are machined from teflon rod. It is item 2 in the picture.

Hardhead I had the same issue. I bought the part for 11.00 on flea hay. Also check with the manufacture. I think I searched the nsn and rounded it up that way. Replaced that part and was good to go.

I could not find the nsn number for that part in the manual I have. If you can find in your history on the flea what it was listed as, I would appreciate it. I might make some out of some alloy stock I have when I can get one of those plastic marvels again! What a pain to remove the pump!! I went ahead and disassembled the pumps and checked them. Just my luck two twisted off plastic couplings and it was 9 degrees this morning! Funny thing both fuel pumps was perfectly clean inside as far as I could tell. I wonder if running the units out of fuel at the end of the year causes this failure.

I have an M82 and it was not running when I got it. I will look for the vendor and part. Yes if someone can make a replacement part other than the plastic one would be awesome.

I had a buddy build a couple for his h140’s, if someone can get dimensions to see if they are the same part that would be very helpful
