    double wall pipe allows such close clearances I'm surprised it could be the culprit here, causing heating of the pad two feet below it? Could there be an area in the back bottom of the stove that isn't being shielded? Or could the shield be mounted incorrectly?

    Pics would be nice...

    The shield has a flat bottom with three flaps that fold out. The side flaps connect to the bottom edge of either side of the stove, the back flap connects to the bottom edge of the back. They slope down to the main part of the shield just under the ash pan. If the installer forgot to unfold the back flap then the heat shield would appear to be in place but would not be protecting the entire bottom. This would explain the higher temperature towards the back of the stove. The ash pan also helps shield the bottom but only the front two-thirds of the stove.

    I feel 200 degrees is too warm for an ember-only hearth on a stove running in the <500 degree range. Something is not right.

    I have a Harman Oakwood, which by most is a large stove. I am also concerned about my hearth. I have a single layer of brick used as a hearth which I knew wouldn't suffice for the Oakwood without the bottom heat shield. According to the isntructions, with the heat shield, the stove can be installed on a non-combustable floor protector with zero insulating value. I've never ran the IR gun underneath the stove but last night, the brick is quite warm to the touch. It's got me concerned now, too.

    I had the post awhile back about my hearth reaching 300. The pad says it has an insulation factor of 1.58. Downstairs underneath the sub floor was just ambient. I installed a heat shield and temps are now 150 on the tile. I'm perfectly happy with that. I noticed the tile has the abilty to absorb and hold heat well past when the stove has gone cold so I actually like storing some heat there.
    A week ago I was over at a buddies house and the tiles under his Serria was nearly room temp with te stove at 650. I guess every stove is a little different in where and how it radiates heat out.

    You are right, KaptJaq. I got my answer yesterday from Jotul. The bottom heat shield is missing! The store I bought it from had asked me to send photos so they could see what was going on, but I called Jotul first and was so pleased they called me back. They said it was OK without the heat shield, but I dont feel comfortable to go much longer without it. The store I bought it from is going to give me one. Do I need the installer to come back & mount it or is it something I could do (easily)? ...Thanks for your input & to others who helped me get my answer. I knew something wasn't right.

    It is something you should be able to easily do yourself. The instructions are in your manual. Unfold it and bold it onto the back & side bottom edges...

    I think you will be much more comfortable with the heat shied in place...

    I have to say that right after the stove was installed I was reading the manual & saw the diagram of the bottom geat shield and wondered it it was attached. Plus I saw four extra nuts/screws left over from the installation. But then I figured of course he wouldve installed it... I did read the manual and it said the attached heat shield before attaching the sides of the stove, so I wonder if the sides need to come off to mount shield? If that's the case, my installer needs to get back here and do it himself. Thanks for your help. You were spot on!

    I haven't done a Rangeley in a while. The document I have for the installation of the heat shield (linked below) refers to the sides of the heat shield not the sides of the stove. See page 6.

    It should be a fairly simple install, the only complication is twisting your hands to work under the stove. Let the stove cool first, then try it.

    I was able to install mine after the stove was set in place.

    No, it was installed before the first fire.

    Well I got the heat shield & tried to install it, but I broke it along the perforations that you're supposed to unfold! Wow, do I feel stupid. Im thinking as long as each piece is screwed in, it will at least have some shielding. Im going to ask my installer to take over bc I dont want to make it worse - do you think I can still use it?

    I have no idea! Probably a really good idea to have your installer take over....good luck with this. A shame you are having trouble. If they had only done the job properly in the first place....

    These aren't awesome pics but you can see the heat shield.

    Nice photos. Thanks so much! Turns out since it heat shield broke when I unfolded the rear piece to attach it I will need to find a welder to fix it so it can be mounted. I may just give it to stove store to get fixed as I'm tired of this saga. If only the installer had read the manual!

    Don't feel stupid...ours snapped at the perforations too when we installed it. Even with the heat shield in place we decided that it was too hot under the stove for our comfort. We had a sheet metal heat shield fabricated. It is on 1" legs and extends the full length of the stove and about 4" beyond the cast iron ash shelf. It is sprayed black, and actually looks like it belongs there. Someday we will have our hearth re-done (it is from another era), but in the meantime this gives us peace of mind.

    Thanks, Heather. That's interesting. I will be looking for a welder to fix my sheet. How much did your custom made one cost? As an aside- I left the broken shield on the floor under the stove and neither it nor the hearth beneath is getting hot. I wonder if it's due to a pretty full ash pan. In any case this whole heat shield thing has been a saga!

    It cost about $100 to have the shield made. I think the full ash pan might help a bit, but I also think this stove generates a lot of heat out of the bottom. Our old stove had firebricks on the floor of the firebox and the hearth never got uncomfortably warm. With the Rangeley there just isn't much between the fire and the floor.

    I agree but still jotul requires only ember protectio with the heat shield so they must be OK with the heat.
