Just Bought a Jotul F3 today.....Hearth Pad questions

[River19]

Alright, so based on some good adivce and lots of reading on this site we opted for the Jotul F3 to supplement the heat in our soon to be built log cabin in northern New England. Should be nice when installed etc.

Now come the questions......

I was planning on building the hearth pad myself and I am looking for some advice. I don't want to raise it too high above the floor so I was thinking of laying something down on top of the hardwood floors......something like 3/4 ply with a layer of cement backer board and slate tiles or ceramic tiles as the finished surface. I need a minimum of 9" in the rear from the heat shield to the wall and I was going to push that out to 12" for peace of mind. I believe US code for the front is 16" while Canada is 18"......so I'll take that into consideration and probably just go with 18" up front. I'll figure out the sides as well (don't know the code off the top of my head).

Am I barking up the right tree on this? Anything terribly wrong with this construction method?

Also, I was originally thinking of going with double walled pipe as the pipe will be going up about 16' in a cathedral ceiling then through the roof via a chimney kit. I believe single walled pipe would radiate more heat off of it but also might need additional clearance from the loft railings etc. I should just stick with the double walled and suck up the added cost right?

Thanks in advance

Yep, Steve, as long as you're reading your stove manual and only need a basic non-combustible pad, you are absolutely thinking the pad portion thru perfectly well. Beware the soft and chippable/crackable ceramic tile, though... get hi-fired ceramic or go with solid porcelain.

I'm not going to attempt to answer the pipe portion of your question, but someone else will soon, I'm sure!

Thanks for the response, I appreciate it.

Any feedback on the chimney and hearth pad?

Thanks

The manual calls for a manufactured hearth pad or one with an R value of 1.1. It would take 4 layers of Durock to achieve this.

Given the length of connector pipe required, use double wall stove pipe like DVL.

BeGreen - Thanks, If I had the manual on me I could have read that, we bought the stove but the store will hold it until the home is ready for the install. We break ground tomorrow, should have the log home dried in by Mid to late December.......so I want to get all my ducks in a row and procure everything I will need.

I guess I'll use 3/4 plywood and 4 layers of rock......should make it about 3.5" high when done. I saw a 3x5' piece of dura rock is about $10, I can probably build it for $125 or less with tile.

Thanks again.

Anyone know what range of R values the prefab stone is that everyone is using for hearths?

I just put in a Jotul f3 in my house. I made my own hearth out of 5 layers of Durock (.26 r value) and then went to the Swenson Granite and picked up a 1.5 inch thick piece of rough cut granite 40" x 41". All together it came to about $380. To clean up the base and hide the Durock I just lined it with a piece of Oak trim. I saved almost $200 doing this than buying one of the pre-made hearth pads.
