Another Harman Mark II Gasket Question...

Hello all,

I have an older Harman Mark II with three separate glass panes. I'm in the process of replacing them and I'm fairly certain the glass gaskets were incorrect when I took it apart. I've found information on the single glass pane doors that say the top and bottom of the glass are left without gasket for an air wash. How should the glass gaskets be installed on a three pane model?

When I took the old glass out, the top was left without gasket and the sides and bottoms were gasketed. I'm fairly certain this is incorrect but can't find any info on the older stoves with the triple glass. Any help would be appreciated!

Tops and bottoms of each of the three panes should be left ungasketed. The side gaskets should extend around the corners top and bottom and then stop.

Thanks for taking time to reply and giving me the info....

Seems not too many folks have answers on the old three pane models, I bought my glass from a local dealer and you would have thought this stove was martian technology. They knew nothing about it. Not to mention their service department couldn't find their nose with their own two hands when I went to pick up my order. On top of it all they charged me hefty freight to have the new door glass shipped to THEIR STORE!

I called another dealer today just after I posted and they said the bottom should be all that's left open as that's where the air wash channels are. Any merit? They were very nice to deal with but didn't seem to sure.....

The three pane Harman mark II's and mark III's are from the 80's. I've restored 2 of them, both I believe had the original glass and the gaskets were installed as I desribed. I've been in contact with the folks I restored the stoves for and they both say it works great that way.
Honestly many Harman dealers don't know as much about coal stoves as you would hope. Some are great though. My local Harman dealer for instance is a chain of hardware stores (4) that sell the lions share of the pellet, wood and gas stoves in my area. Their advertising budget is big. They never mention coal in any of their advertising.

if you need parts for the Harman's the best dealer I know is fisher stoves been selling them forever(I know been buying from them forever ...lol) ask for Dave or his wife there great people and are very knowledgeable on the Harman coal stoves.

and for the most part he would more likely have the glass in stock for that stove. when I rebuilt my mag stoker this fall he had every part in stock that I needed.

I agree with RayJay and recommend Fisher stove shop if you are in the area. They have been my Harman dealer for about 13 years. I make the 70 mile trip from Eastern Broome County in NYS to Factoryville bypassing several inferior dealers. Their shop is not a pretty showplace but they will have every part you will likely need. The owners are good folk with lots of experience. They will not lead you a stray just to make a sale. I have purchased a Mark III and a SF260 from them. They always have the parts I need at a fair price. Good luck with your project. Tom

Mark,
I have the same stove as you with the 3 glass panes. Mine was refurbished at the Harman factory and new glass was installed at the time. The gaskets were installed as you describe and I have had no problems what so ever. I have been burning this stove for 17+ years now.

Which way are your gaskets again? I've talked about so many ways I'm not sure which your referring to! LOL

To experiment, I installed the gaskets leaving only the bottom open and fired it up. It burns quite fine, but I can see how the air wash would work much better with the top open as well. It seems to me that's the way it was designed as many of you have pointed out. I plan on removing the gasket from the top of the panes as well..... thanks for all the input!

The stove was in the house when I bought it 1.5 years ago. The only thing the previous owner burned was a substance that resembled oregano.... needless to say, a set of gaskets and cleaning was all that stove needed to be the primary heatsource despite the previous owner saying it didn't burn well.

Jeff,

As for getting parts, I went to a dealer local to where I live in Glen Rock which is in York County. What a mistake! I'm very familiar with the folks at Fisher Stoves as I'm from the Tunkhannock area. My Grandfather always burned Fishers. From now on my parts will be picked up on my trips home!
