mkadyz,

The site you had for the service manual pulled it down, could you email it to me?

Thanks, Jeff

all the heaters I've ran against, I have yet to see round compund gaskets. besides once the silicone is flattened they stay that way. cloth type gaskets although get flattened are resilient enough to "bound back" when tension is relaxed.

HayZee518 thanks for all the posts, I meant to ask about using the cement in place of the gaskets not with the gaskets.

ok, you said the fuel ran out. first thing to check is a clogged tank filter. change the felt filter. next, disconnect the fuel line at the tank and heater and blow it out with compressed air. remove the two screws to the right lower of the fuel sump and clean out the stainless filter behind it. put everything back together and re-start the heater. listen and check what happens.

Vary informative, thank you for your efforts.

I tried to start a new question on this form but was at a loss how to do it...

I have a 422 n for years it has operated flawlessly.

This year it started right off however after the first tank ran out, I refilled the tank but after attempting to re start it, it shuts down and all the burn states lights blink together.

Any idea where to start.

Thank you, Glennnnn

The original service manual link isn't working anymore apparently. I will try to get a new one up as soon as possible. If someone wants to host it for us, please let me know.

well its heating season again, so back to working on the monitor and checking this thread again.

MKADYZ - How has the Permatex Copper held up on the exterior gaskets? I'm deciding which way to go with the gasket rebuild.

The permatex doesn't appear to have worked very well in place of gaskets. I used it all last winter without problems, but it does appear dried and cracked in a lot of places. I haven't torn the burner down yet this year, I will probobly do that next week. When I do, I will most likely scrape off the permatex and replace it with the generic woven material from McMaster Carr. I used burner cement to glue down the burner mat. I will keep everyone posted with what I find when I tear it down next week.

you'll have to contact the user direct. I only used rutland cement on the burner mat - nothing else! all other gaskets do not require a cement.

I sure would like to find a Service manual and parts list for the MPI 441 if any one out there has one.

I would like to thank mkadyz for his fine work and I would like to make my 5 post in order to down load the service manual.

Looking for a 441 Manual?

"mkadyz said he posted a pdf of the Monitor 441 service manual on the MediaFire site."

That was "mkadyz" that said that, not me (Lucid, with a 422).

You need to reply to the mkadyz post and hope for a response.

look around the forum. the user that scanned and uploaded it meant to share it. it is not restricted by us or mpi.

Is the service manual site something you can share?
