Fresh Air Intake | Through Heat Shield or Floor?

[Kilo_117]

Summary: Should I run the fresh air intake through the heat shield and then through the wall? Or through the floor and then out through the skirting?

Full Description: I am installing an Ashley AW1120E caddy corner in a manufactured home and must have a fresh air intake installed. The issue I am having is the seemingly limited options to access the outside air. Do to the design of the home and where the stove needs to be placed it seems I have two options.

1. I can run the fresh air intake through the 26 gauge steel heat shield and through the outside wall. This would be my preferred option as it seems easier to do, although I’m not sure if that could be a potential fire hazard.
2. Or run the air intake down through the hearth pad and floor and out through the skirting. This option would have a longer intake and will require at least one, maybe two 90 degree bends, which I was told could be an issue, but I haven’t been able to confirm if that is true.

Any guidance on this is very much appreciated.

Thanks!

*A note on the images provided: In case this is relevant to your answers, I am still in the planning phase of the installation and am trying to map this project from beginning to end before starting. The blue tape marks the outer edge of the hearth which will be 50 inches from the wall to hearth side edges, and giving me 16 inches from the front of the stove door to hearth pad front edge, and roughly 12inches from the back corners to the heat shields on either wall. At the moment I am planning for the hearth pad to be a sheet of durock then a layer of spaced apart bricks for additional spacing and an air gap, and then three layers of durock with some kind of roughly 3/8 inch decorative slate on top. The electrical outlets will be removed.

If the skirting is not air tight, just go thru the floor and end below the floor without 90inh out to the skirting.

Does anybody have any links regarding OAK installation, or documentation either by-laws, or building codes or manufacturing installation guides or any other.

In my understanding, in the US and OAK is mandated for manufactured homes (because they are so tight).

The way to install the OAK should be described in the manual of the stove it is meant for. So that would be the documentation you need.

I vote wall. Nothing wrong with it as far as can’t tell from your description.
