Munchkin Venting

Vertical venting is best and the wall hung is vented in two inch. If you need to exceed 85' toltal combined venting then you must apply the extended venting instructions. This would require you jump up to 3" at a minimum of 5'from the unit for both intake and exhaust and no greater than 15'
If you should have any questions you can call tech support or go to our web page at www.htproducts.com or click on the link here under the manufacutres section and down load the LP-61 Munchkin manual for reference. BO!

    Munchkin Venting

    Hey All,

    I've got a client whose local Munchkin seller is telling him he can vent the wall hung unit vertically up through his roof with 2 or 2.5" PVC venting.

    This is about 25-30' rise, and the client is thinking of putting the vent within his outside wall for the rise (he has ICF construction, so there is a space there).

    Has anyone seen or done anything like that out there? Seems a little... odd..

    Why not?

    are you concerned about vertical or pipe size?

    I know contractors are venting them thru 2" when old Hydropulses are removed. HTP has special derate tables for unusual venting options. Best to get their blessing on any method other than that shown in the venting manual.

    well we don't handle this end of things typically, and just the thought of venting up through an outside wall, even an ICF one, seemed strange. Just wondering if there is a big no-no we could help rule out a possibility with for the client at this stage. Thanks for the feedback HR!

    Outside wall

    shouldn't matter. We vent through unheated, open ended attics all the time. I have seen guys run them up the outside of buildings. Some chase them in some not.

    Wherever you install them be sure to have nail protection. I laways cringe when I see a 3" PVC vent in an exterior wall and a siding contractor with 12 penny nails in his gun!

    Nice to know Jeff, thanks a lot for posting! We have tried talking to HT tech support in the past though, and it seems if you are not a vision certified installer, they just aren't interested in chatting. That's kind of rough, since while we don't sell or install boilers, we do design systems around different heat sources and our clients are always asking for recommendations...
