Update on problem oslo installation

[atomichawg]

I posted a thread a while back about a problem with an installer when they couldn't cut through the damper due to it being super tough healilator steel. They had broken 2 sawzalls on it. Well the dealer agreed to pay for someone to come out and cut through it with a torch, and that was done a few weeks ago. So yesterday the installers come back to drop the liner and hook it all up. Both me and my wife were at work. When I came home, the following issues were evident.
1. The stove legs in the front were hanging over the edge of the hearth. Not by much, mind you. Move it back a half an inch or so and it would be golden.
2. The spark protection pad which sits in front of the hearth was smushed and scraped in some spots. Clearly they had set the stove on it and moved it around some.
3. They were supposed to mount a mantle shield, but did not bring the spacers for it. (DOH!) They left it sitting on the stove. For some reason, they had cut it to make it narrower, and had left a fairly uneven and very jagged edge.

Are these legitimate concerns? I called the stove place and they are supposed to send some people out soon to install the mantle shield and hopefully address the other problems. Who knew that installing a stove could be such a pita?

I feel your pain - can't comment on your issues - I'm sure others will. My Oslo is sitting at the shop - my liner arrives today. Having had no end of terrible advice from the people offline (and great advice from here), I'm just going to suck it up and do it myself.

The dealer should make it right. Move the stove back, new hearth pad, file the cut edge of the shield smooth and install it with the proper spacers. You paid for a new install, it should look like a new install!

Just added pictures. What do you think?

Hallelujah! Just got off the phone with the dealer. He agreed that the installers had screwed up. He is sending out a different crew on Tuesday to fix everything and replace the pad. This will make 4 times that someone has come out for this dang stove! I can't imagine what it must be costing the dealer to keep sending folks out here. What an odyssey!

wow. honestly thats crazy. Stove 101 would tell you that you need a hearth that is at least 16" from the front of the glass, and if my memory serves me, that pad has to be a UL1618 rated pad with somewhere in the neighborhood of a R1.2.

 

[begreen]

This is one of those grey areas in Jotul's docs. The manual only calls for ember protection with a non-combustible shield. But if you go to the section that describes how to build a homemade hearth, then it gives chapter and formula coming up with R 1.2. In the very least I would expect an inspector to require that the pad be captive and not free-floating on the floor.

great info BG, i have not dug around in the most recent Jotul manuals. Two seasons ago they did not describe ember protection as a qualifier for there hearth requirements.

 

[stoveguy13]

if the oslo has the bottom heatshield it can sit on any non combustible flooring

 

[MountainStoveGuy]

In the current manual, this is what it says! a far cry from what it used to say. I thought the bottom heat shield was only for alcove installations... i will keep digging.

In the U.S. and Canada
The Jøtul F 500 must be installed on a non-combustible surface
extending:
A minimum of 18” (457mm) in front of the stove and the left side
load door (measured from the legs).
And 8” (200mm) on the right side and back of the stove (measured
from side and back panels).
This will result in a minimum floor protection of
54,25”W X 50,5”D.(1378mm x 1283mm) See figure 8.
In a rear vent installation the floor protection must also extend
under the stove pipe a minimum of 2” (50mm) beyond either
side of the pipe.

I came to the same conclusion - ember protection only unless installing in an alcove - the alcove protection is the the only section that refers to Appendix A, which is where you find the "alternate" hearth protection. I do remember someone, somewhere saying that they had confirmed this with Jotul (someone, somewhere - sure that will stand up in a court of law....)

I was going to do ceramic board under my tile and cement board, but as I wanted the hearth to be flush with the floor I ended up ditching the ceramic board.

I do remember that any gaps in the non-combustible hearth must be sealed - i.e. grout between tiles lying on plywood. I don't see quite how your setup would pass my (naive) interpretation of the code.

I also came to the same conclusion when I installed my Oslo last year . . . who knows . . . perphaps things have changed but at the time only ember protection was required, except for alcove installs . . . but because I'm a safety guru and would never live down the fact of having my house burn down if I failed to build the proper hearth protection I called up my Jotul dealer who called the Jotul folks and they confirmed that ember protection was the only requirement for the Oslo if this was not an alcove install.

And even then, I opted to build in a little more R value (not a lot) by going with listed Durock for that added measure of security . . . but again, that's the anal retentive worry wart me.

I'll guess that you're my "someone, somewhere"...

 

[atomichawg]

Found this one online. Seems kinda pricey, but I am leaning towards something better than a flimsy black mat. If anyone has a suggestion for a reasonably priced 18 x 48 hearth extension pad, I'm all ears.

As you only need ember protection, I would look to get tile as close as possible to your current setup, add 20" of cement board screwed and thinset to the floor, then the tile. - will be considerably cheaper than the r-rated heart pad you don't need - getting the height right would be tricky though....

 

[fredarm]

That's a nasty ragged edge on that heat shield. I wouldn't want that anywhere near my mantle!

After running our Oslo at 600F for >1 hour our black matt (sheet steel from Morso sitting on ceramic tile) is not that hot -- you can leave your hand on it indefinitely. This is WITH the bottom heat shield. So regardless of code or UL Listing requirements, it is certainly safe.
