Do I need a hearth pad?

[Tanner]

Hello all.
I've looked around and cant find a answer that satisfies me. I just installed my Jotul firelight 12 in the house and didn't drop a pad down. Reason being is that I have ceramic tile throughout my living room. 1/4" commercial stuff.
I personally don't think I need one, and the onwers manual was really vague. Do you guys happen to know where I can find this info out? I attached a pic. Tell me you think.
Thanks in advance.

If this is the right manual for your stove, I only see it listing a non-combustible surface as the requirement (which you have).

Here is the link (broken link removed to http://www.northweststoves.ca/pdf/jotul-wood/m-firelight-1.pdf)

You are good to go, the F12 Firelight just requires a non-combustible hearth which you have. It looks great there.

If the subfloor is plywood / if the tile is on anything other than a cement slab, then it seems the K or R value rule of the stove manufacturer would come into play. Otherwise anyone could just lay tile over their wood floor and call it good, but everyone out there that I've noticed has been scrambling for Micore 300 or building up their pad to meet certain mfg. R/K value requirements.(broken image removed)

There is no K or R value requirement for this stove. Simply a non-combustible surface.

page 10 of that stoves' manual states ;

"if a listed (UL/ULC) hearth board is NOT used the hearth that is constructed MUST have a minimum R value of 1.6



But then on page 19 of that same manual it says this;

For the Jøtul Firelight CB woodstove requires floor protection with a MINIMUM R VALUE OF 0.5.
ALCOVES REQUIRES R VALUE OF 1.6


My guess would be if the subfloor is on a concrete slab it wouldn't matter.

Yea, that's for alcove only the way I read it. This guy isn't using an alcove. Must be they figure more heat will be stored in the enclosed space.

I'm not familiar with the stove at all, just going from benchwrench posted I'd assume it requires floor protection with a MINIMUM R VALUE OF 0.5 anywhere and a higher R value for an alcove.
