Hi - there are two ways to install the outside air kit on a Harman XXV - one uses part number 1-10-08542 and one uses the wall pass through part number 1-00-677077.

Does anyone know if one method is better than the other in any way? I think the second part number might cost more - is it worth it?

Thanks for any information.
 
Its a pipe for bringing in air. There's one on E-bay.
Depends on how fancy you want to get. Depending on the location, I would insulate the outside of the pipe. A 20 degree pipe will cool some air.
My outside air comes from the crawl space, right through the floor. I used 2" plastic sub pump hose.
 
All stove manufactures state OSA hose should be metal only.

I agree...I have only seen metal pipe listed in Installation instructions.
