My new insert will be at least 5" above the floor.
I interpret the following excerpt from the manual as saying all I need is ember floor protection 16" in front of the door opening.
Am I correct?




Floor protection must be non-combustible, insulating material with an R value of
1.1 or greater.
* Hearth thickness of 0.5" with k value = 0.84", R value = 6 or greater.
** A non-combustible mantel may be installed at a lower height if the framing
is made of metal studs covered with a non-combustible board.
Thermal fl oor protection is not required if the unit is raised 3.5" minimum (measured
from the bottom of the stove). However, standard ember fl oor protection is required.
It will need to be a non-combustible material that covers 16" (406 mm) in the US and
18" (450 mm) in Canada to the front of the unit and 8" (200 mm) to the sides.
If the unit is not raised, thermal fl oor protection required is 18" (450 mm) in the
US and Canada.
All fl oor protection must be non-combustible (i.e., metals, brick, stone, mineral
fi ber boards, etc.) Any organic materials (i.e. plastics, wood paper products, etc.)
are combustible and must not be used. The fl oor protection specifi ed includes
some form of thermal designation such as R-value (thermal resistance) or k-factor
(thermal conductivity).
 
that's what the clearance is for my quadrafire yosemite, which is a free standing stove. mine is on my fireplace hearth which is only about 18 inches wide. I added a thin black HY-C stove floor protector that my installer had in his truck.. so happy that he did because i was prepared to use this $400 monstrosity I found at home depot.. the floor protector
was fine with my city inspector and looks much better than my alternative.

anyway, my stove has front and side doors, and each need 16".
 
This is what I did. A wool rug with a brown stone step on top of the rug. This is all I need because the insert is on a raised hearth. This passed the inspection by the installer and the town sign off.

Thanks.

I like the lattice on your door. Mine won't have that.

Is the lattice an option on the door now or is it not offered? Just curious.
 
That's pretty much the same wording from our Regency manual (Hampton/Regency same parent, so makes sense they would have the same specs for a lot of things. Yup, if you have a raised hearth at least 5" above the floor, you only need ember protection on the floor for 16". I still put 3 ft X 6ft of slate tiles on top 1/4" micore on top of a metal heat shield on top of sub floor (my installer suggested the heat shield - thin sheet of galv steel screwed to the sub floor.)
 
I have to add more floor protection than was already there because this insert projects more into the room than my current insert.
I just tore out the old ceramic tile and the 1/2" micore underneath and cut out the wood floor. Man, I tried really hard not to screw up, but I still did some, but not too bad. I'm going to put down 1/2" of microre and black granite tile on top. Alas, the granite tile is 3/8" thick and with the micore, adds up to 7/8" without a thin film of thinset, which will make it a little proud of the 3/4" wood floor. Not quite flush, and I didn't need to, but I wanted to use up the micore sheet I had in the basement. :)

The stone tile seems a lot more substantial than ceramic.
