Hello,
First post. I'm new so please be kind and gentle. My wife and I recently purchased a Jotul F500 and we have a couple questions. It was made September 2007 and SN: 50033.

#1: manuals/documentation
Where can I find the exact owner's manual and documentation for the stove? Is it a v1? v2? What about clearances? The placard on the back of the stove says 18". Does that mean single-wall stovepipe? We have the rear heat shield. Where can I find documentation that says what the clearances are with double-wall stovepipe and with the rear heat shield?

#2: proper sizing
The F500 is slightly oversized for the house. The house is drafty, the insulation is not great, etc. so we figured that going a little over-sized wouldn't be terrible. We figured that we can run the HVAC system (forced hot air) on fan-only mode every 15 or 30 minutes throughout the house to circulate the heat. It'll be fine, we will figure it out, it'll be a learning process, etc. Is that a fair assumption to make? I'm not that concerned about efficiency (we have plenty of wood). But I also don't want to create a maintenance nightmare with cleaning, burning small fires in a big stove, etc.

#3: restore/paint
My wife found this thing on Marketplace. We rented a u-haul pickup truck and we paid $500 for it. I am a car guy so I have contacts with people who do media blasting. The prior owner said it had only started to rust when he took it out of his house and moved it to his garage. But there are leaves and small pine branches in the top cook-top plate crease --basically I'd bet that he had it sitting outside on his back porch for a few days/weeks and it got rained on a few times before he moved it to his garage. When I opened up the front and side doors the gaskets pulled off and stuck to the stove.

At what point do we make the decision to f'it, replace the gaskets and learn the stove as we burn next winter... Or do I just break it down, dissemble it, send it out for media blasting... And then what? I own paint sprayers. I could have it blasted at a shop 30 minutes from here. Just wait for a low-humidity weather window and have it blasted, then take it home and spray it? Then what? Assembly is opposite of disassembly?

Or do we just use it as-is and made educated decisions next year once we have a year under our belts? I just don't want to have a bad experience with the stove up-front and hate it. But I also don't want to nuke the thing and go crazy restoring it back to factory/brand new for no reason.

What is the difference in finish quality between using a wire brush and paintbrush (or spraying myself) vs. having the entire stove media blasted and spraying it?


#4: supporting floor under stove/hearth
We are really close (really really close) to the load/span tables for where we want to put this stove. It is 2x10 16"OC and a 13 foot span. The joists run left-to-right or right-to-left of the stove (NOT FRONT TO BACK). Without getting into it too much: This is my father in law's house. My wife is inheriting it. He did home hospice until the end. We are putting this wood stove exactly where his hospital bed was. And his hospital bed was heavy enough (his hospital bed was perpendicular to the floor joists) that by the head of his hospital bed there are depressions or the floor is buckling. You can see that the hardwood floors were pushed down from the baseboard moulding in the room (from the weight of my father in law + his hospital bed).

It is pretty much (not exactly 50% but more than 1/3 --maybe 3/8 or 5/8) in the middle of a 13-foot span of 2x10 16"OC floor (basement ceiling) joists.

What does someone do? Does it have to be a permanent house structure change? Do I need to cut a hole in the basement slab and build it up with a metal column like a deck (dig below frost line, anchor it in concrete, etc.) or can I use the slab directly as a structural base? Do I need to build/pour a square on top of the basement slab to support a column?

I asked "does it need to be permanent" because you can buy those "screw type" columns from HD/Lowes. But I can also weld so I don't care: I'll buy a column/metal tube and measure once/cut twice, weld it short and then curse myself that I should have hired it out and let someone else deal with it.

What do I need to do to support a hearth in the middle of a span? I don't really want an LVL across the bottom of those joists in the basement. But if that's all I can do then that is what I need to do.

Other stuff:
I grew up with a wood stove. My wife is 1,000% on board but I think she has no clue how much work the firewood part is going to be. When I was a kid my brother and I had boy's axes. When we got in trouble dad would hand us our axes and say "split that pile before your mother serves dinner or you don't get dinner". That was our typical punishments for being idiots. My wife has never had a stove and we decommissioned the fireplace in our house. We have the wood part sorted: Her dad's property is several acres and there is many, many oak and hickory trees that have fallen or are standing-dead for years and years. I did some tree work, summers during college years. It was a long time ago but I still own and use the Echo 30cc climbing/top-handle saw my dad gave me. We also have her dad's 42cc Poulan saw, and we just bought a new 372xp Husky saw. We have ordered about 8-cords of unprocessed log-length (green) wood from a local tree service, and I think I can harvest or pull 3-4 cords out of the property that has been dead and dry for years and years. So we have a start, and a future and a plan for firewood going forward. And we own PPE. I'll weld/build/DIY my own hydraulic splitter probably next summer when I get sick of using axes and mauls to split.

It just skipped my mind about the weight and the load/span tables and supporting the stove+hearth.

Couple other random questions:
Does 5/8 firecode drywall play any part in this? Or is firecode X drywall considered a combustible?

The stove will be backed up to an exterior load-bearing wall. We need to do a ton of work to my father in law's house. Is there any way to replace the combustible studs and exterior sheathing, etc. with cement or Hardie such that the entire wall surrounding the stove will be non-combustible? Metal studs and cement/fire board? Then tile over that to make it look pretty?

Is an LVL with a column my only choice? I think it would be cheapest but it would be disruptive and ugly and potentially interfere with space requirements around HVAC and the circuit breaker panel. Should I consider an LVL (or two) to sister the existing 2x10 floor joists?


Thanks for reading our questions and happy to answer questions to get more feedback from you all.
 
Did your stove come stock with a cast iron baffle or with a vermiculite baffle?

This is the 2009 manual.

In the manual you will see clearances listed in the table for Protected Surface. If the wall has a proper, NFPA 211 wall shield (which can be tiled) then that is the clearance to the sheetrock or studs behind the shield. The clearance can be reduced down to 6" if the stove is connected with double-wall stove pipe and has the rear heat shield mounted to the back of the stove.

No mention of a chimney. I’m assuming there is none so that would be another consideration.

I wouldn’t media blast it unless you’re after a factory finish, a wire wheel and/or wire brush is usually sufficient for surface rust.

As far as the structural questions go a carpenter should be able to give you an idea of what you need to do if anything.

I believe 5/8” gyprock is fire resistant not non combustible.

Once you get the owners manual a lot of your questions regarding clearance to combustibles will be answered.

I don't really know what that means. Baffle, fiberboard baffle ---I don't know what that is. Where would that be and can you guide me to I can take pictures and y'all can teach me or show me? Are you talking about a flue on the stovepipe? No it's just the exhaust casting. Do you mean with the air intake? It's just a rod that moves left/right to open/close air.

Inside the stove it is fire bricks along the back, something up top that I haven't explored yet... And it looks like there are round tubes with little holes in them (looks like our Weber gas grill) running along the top. I don't know what the baffle is or where I would go to look for it.

TY for the nfpa reference and heat shield+double-wall reference. I've done homeowner permits for electrical work (which is part of nfpa). I just want to make sure this is squeaky clean and no issues with inspector. Whenever I question something I'd rather exceed vs. try to pass min specs.

Correct. No chimney. Dad's house (my father in law's house) does not have anything. No fireplace, no wood stove, nothing. I'm going to need to cut a hole in the wall and screw a stovepipe to the side of the house.

The visuals and appearance: I'm after "happy wife, happy life". She wants it to look factory new. So how different is a wire brush and paint brush (or spray gun) vs. sending it out to be blasted and at that point I'd probably pay someone to paint it and re-assemble it.

Structural: That's my biggest concern right now. This is a weird life experience. It is the house my wife grew up in. Her dad did home hospice and he passed almost a year ago. My wife is still the trustee and executrix of the estate and we are in the process of "buying the house" from her sibling (the second equal share beneficiary). It's just weird to be in my father in law's house. He didn't take care of his house. It needs a lot of work. I am not a contractor however my wife wants to build an attached 2-3 car garage with a bonus room above. I'll do that work myself. (or maybe we will hire a crew to frame it and dry it in and I'll finish the rest)

I looked this morning and saw that several of the floor joists were cracked and broken. I guess I'll strip the siding from part of the front of the house and slide in LVL's or additional 2x10's and sister them to the existing joists. Jack it up, sister new joists and as long as the inspector is happy then it's fine. That part is easy: span tables, code, etc. I'm just trying to avoid tearing up the hardwood floors my father in law put in a few years ago. I didn't want to tear up the floors and drop in wood/joists from above. So I'll slide them in from the front of the house.


Thank you all for your views and answers. Much appreciated. Thanks!
 
The baffle sits on top of the round tubes with little holes in them. They are the secondary air tubes to feed the fire additional air for more complete combustion. Considering that this is a first stove and its age, the F500 should be gone through very carefully by a professional that knows this stove. It's a wonderful stove, but the castings should be checked inside and out, the baffle and insulation blanket on top of it inspected, and all gaskets checked for seal.

That is a whole different concern: I don't even know where to look for to find cracks. I can weld and I have no problem welding cast iron engine blocks for cars ---but I have no clue about wood stoves. I do not in any way want to be cocky or ignorant about this. If we have cracks I'd rather sell it and buy something new (vs. me try to weld it and then we die in a fire-or gasses).

We risked $500 and bought a stove. What do I do next? We need to support the floor where my wife wants this thing. We bought a bunch of wood and an expensive chainsaw (372xp Husky) so we are committed. I have tools and nail guns and stuff. I can do grout and float concrete... I understand IBC (international building code) and loads --but that's mostly for roofs and snow loads. Our house is single story on a slab. My father in law's house is two stories with a basement. My wife and I have never lived in a house with stairs. I need to support this thing from the basement somehow. Sounds like the hardest way will be the best way: strip the front siding around the foundation and slide in 2-by or LVL's and sister the existing joists to strengthen the floor. So it is what it is.

Squirrels and woodpeckers have destroyed my father in law's house siding either way. We need to replace it no matter what... So might as well F-it-up even more before we re-side the house. Cut a hole in the front of the house and slide in new beams to sister to the broken floor joists. Make inspector happy and call it done.

What is this baffle thing? Can I take pictures and upload them? I don't have a clue about what I'm looking at. I thought that providing 50033 serial number might date the stove and that would answer some questions.

Thank you and I appreciate the help. Thanks a bunch.

EDIT:
I've read that there is grout in there? What is this thing with grout and fire-bricks and concrete in it? When I was a kid it was just a cast iron box that you burned wood inside. Grout, concrete. Air tubes....

Can we just drop it off somewhere (new england, rhode island) and pay to have them make sure we have a decent stove for next winter?
 
Tubes have been in secondary burn stoves since the mid-1980s, baffles even farther back. I don't have a stove for showing pictures. Hopefully someone that has an F500 will post some shots. In the meantime, can you post some pictures of the inside and outside of the stove?

100% yes I will post some pictures. It is out on our front porch right now. I plan on getting it into the house tomorrow. I can post whatever pictures you need to see to help once I get it inside and it won't get rained on.

Thank you all for the wonderful welcome to hearth.com.

When I was a kid all I knew was when I got in trouble dad made us split wood... And then you put wood in the stove and it gets hot and burns. I don't really know anything about the wood stove, the firebox, air flow, etc. I was part of a competition BBQ smoker team a few years ago and I'm the guy who did the metal fab work to build the smokers. And I clean and maintain my own Beckett oil burner. So I understand a little bit about burning fuel to generate heat: But I'm clueless with wood stoves.

Thank you for the help. I'll get the thing in the house tomorrow and post some photos once it won't be rained on. Thx.

Depends on how bad the stove is pitted from rust determines how aggressive you need to be with surface preparation. I’ve had good luck with a wire wheel and brush and spray bombs of high temperature paint. Mine was pitted bad but I wasn’t after factory new finish. Turn the orange rust to black.

Sounds like you have lots of structural work to get done before any stove installation, good on you to be thinking ahead about extra support for a stove.

Any idea what caused the floor joists to crack and break? By replacing them won’t the new ones crack/break unless the underlying cause is identified and rectified?

Good luck

Floor joists: I don't know how to say "I got it" without sounding like a jerk. This is the house my wife grew up in. It is my father in law's house. We lost my father in law about a year ago. He did home hospice. My wife took an unpaid FMLA leave and she moved back into her dad's house to care for him. (my wife is a nurse). I was there 90% of the time but we have two dogs and dad didn't like dogs. So I went back and forth doing groceries, errands, laundry, cleaning (and our dogs)...

When my father in law did home hospice his hospital bed ---not just his hospital bed. We moved around all of the furniture. Where we are going to put this wood stove is where his head and shoulders were in his bed. The whole weight of the electric hospital bed motors and stuff is where we want to put this stove. And we moved around the couches in his living room because someone always needed to sleep next to him. Sometimes two people, one on either side, because we needed two people to shift him and turn him and keep him comfortable. My father in law's hospital bed, commode, equipment, extra people, etc. etc. (plus family visiting ---lots more live load).

That's what did it.
I didn't want to sound like a jerk. If I told you "FU I got it" I would sound like a jerk. But I didn't know how else to communicate that I understand why and how parts of his home were compromised.

Think about this:
I have to get this permit application done and drawn up... And then my wife and I need to wait until we buy her sister out of the estate before we can apply for the permit and start installing it. At least it is in the house (over the beam between living and dining rooms) so now I can take photos and ask more questions about paint and finish, where to look for cracks, etc.

Thanks

You didn’t sound like a jerk. Too much weight, a one time event. I was curious that’s all, I’ve seen floor joists bend but never break. Sounds like you have lots of work ahead. Good luck.
