Harman P43 combustion blower

Only your Combustion blower needs a gasket.

The Convection blower takes air from your house and blows it through your heat exchange system and stays in your house. No CO = No Gasket needed. Pretty much all stoves (Some do use them/my englander is one of them) do not use a gasket on the convection blower. My Quad included.

If you can't figure it out let me know, I will pull mine tomorrow and take a look.

Thanks Dex, however it's my combustion blower I was referring to. No gasket, no nothing. I was surprised. After I removed the impeller I only had to remove three nuts and the blower came right off nice. That's when I got thinking. I am a relatively new owner so I am kinda wondering if maybe the factory forgot the gasket or something. Trying to find out for sure isn't real easy even with a parts list. Still googling.....

Is it where the motor itself mounts to the housing for the exhaust? The motor mounts to a plate with 3 screws on my Quad. There is NO Gasket there. There is a gasket where the plate and motor mount to the exhaust housing. This has 6 screws. There Should be a Gasket there. If you had to pull the impellar, then I think you removed the motor from the plate. My Quad or my Englander have a gasket there ( 3 screws) there is a gaskeg behind the plate with 6 screws. Harman may be different. But I doubt they are in this aspect.

Hi,
I removed the combustion blower today to clean and was amazed at how easy it was to remove. I just had to remove three nuts and that was that. Now my question is how does this particular setup work without needing a gasket? It isn't a sealed system and it surprised me. I am hoping someone can enlighten me. Thanks!

If in doubt, contact Eric at Kinsman stoves...he is a Harman dealer & certified Tech....I'm sure he can help you out.

330-448-0300 or send him a PM.

I'm not sure about the P43, but the Accentra insert I have is gasket less.
If all else fails check the owner's manual:

"The gasketless seal relies on an extremely close tolerance. Therefore, anything other than a clean joint may cause exhaust gasses and/or flyash to escape."

It's one of the things I like with the Harman, cuts down on the maintenance cost a little.

nope....no gasket on the p43 combustion blower OR distribution blower.......

No they do not use a gasket on the combustion blower. The older Harmans are slightly different in the removal of the motor itself but the new models are much easier.
