Mobile Home installation

[Joe the Goat]

Hi guys!

I've been installing my wood stove the last few months, considering everyone's advice here along the way! But now I have a question of my own...

I'm installing the Pleasant Hearth HWS-224172MH (https://www.walmart.com/ip/Pleasant...Wood-Burning-Stove-with-Blower-Small/21264177)

I'm almost finished, and working on the hearth. I have to hit an R value of 2, and between that, and desired rigidity, I've got (from the bottom up):

Thin trailer subfloor
23/32 OSB
1/2 Micore 300
1/4 Hardiebacker
1/2 Micore 300
1/4 Hardiebacker
1/2 Hardibacker 500
Ceramic tile

These layers are dry fitted, but not yet thinset or permanently fashioned, except for the tile, which is not in place yet.

Now, since it is a mobile home, I have to run a outside air intake, a ground wire, and bolt the entire thing down to the floor.

My question is, won't the heat from the stove just travel down the #8 copper wire, and/or the 3/8" threaded rod that will bolt it down, bypassing my expensive hearth?

Thanks for reading!

I mean, I have even read about concern about the nails and screws holding down backer board transferring heat down through the hearth material, bypassing the insulation. Surely a copper ground wire, let alone a 3/8ths threaded rod, would be worse!

Skip the in between layers of hardibacker. Instead start with a 1/2" plywood bottom, then 1" micore, the 1/2" Durock.

Ground the stove where it bolts to the hearth.

Thanks...The micore felt so soft/spongy, that I thought I should stiffen it up.

With thinset between each layer, you are saying it will be strong enough?

Thanks for replying!

Micore is soft. If you want to stiffen it up, put a double layer of Durock on top and stagger the seams. No need for thinset between layers.
