Wood Cookstove Clearances

Disclaimer: I am not a woodburning expert.  I do not claim to know everything about the codes for installing woodburning appliances of any nature, so please consult with contractors, building inspectors, fire protection agencies, and your insurance providers before installing any woodburning appliance.

A longtime, faithful blog reader posted a comment this morning, and here is an excerpt:

"While I love the look of the older stoves, I have been leaning towards a new stove due to the smallish space I have in which to place the stove. It is my understanding that greater clearances are required for the older stoves. I note that the pic of the stove in your summer kitchen shows your vintage stove very close to the walls. Can you talk a little about clearances?"

She is quite right that the green and cream Riverside Bakewell is installed very close to the wall in our summer kitchen.  The picture at the top of this blog shows that it is basically up against the wall behind it.  This wall is protected by 1/4" cement board mounted to the studs with ceramic electric fence insulators used as spacers.  There is no drywall behind the wall protection.

This picture shows the wall protection behind the
stove in the summer kitchen better.
However, it is very important to note that we were only able to do this because we do not carry insurance on the summer kitchen.

For the installation of any vintage wood cookstove, the most recent requirements that I have say that the clearance from the stove to any combustible wall (or furniture, etc.) is 36".  The required distance between single-wall stovepipe and combustibles is 18".  These distances can be cut in half by using approved wall protection.

Furthermore, the reader is correct that newer stoves often need lower clearances.  This reason for this is twofold:

1. Most new wood cookstoves are tested and certified by Underwriters Laboratories.  They can establish different clearances for different sides of the stove, etc. 

2. Many new wood cookstoves are equipped with heat shields which are standard parts of the stoves' construction.

Such is the case with our Margin Gem.  The entire rear part of the main body of the stove is covered with a heat shield.  This makes it so that the rear clearance from the back of the Margin Gem to a combustible wall is only 6".  This was a major consideration for us as we chose our stove.

Our contractor fireproofed the wall behind the stove so that we could reduce the clearances to 3", but the stove actually sits nearly five inches from the wall to accommodate the bend in the stovepipe as it makes its way to the chimney.

As I mentioned before, most new stoves are UL listed.  Your home insurer may require that your wood cookstove be UL listed, which would then make it impossible to have a vintage stove, so be sure to look into that before purchasing.

If space is a concern, many great new stove options still exist, so don't give up the dream!

P.S. (12/28/2013)  It occurred to me to add that stove owners need to exercise some common sense, too.  When I purchased the Qualified range, the installation instructions that came with it said that only 8" of clearance were needed on the right (non-firebox side) of the stove.  This was not a concern in either of the places that it has been installed so far since nothing was that close to the right side of the stove.  However, after operating the stove, it became quite obvious that the 8" listing was for Qualified ranges which were equipped with a reservoir.  I don't believe that 8" would have been at all safe for that stove's right side.

Purchasing a New Woodburning Cookstove

Those of you who have been following this blog or know us personally know that a year ago this month was when we ordered Marjorie the Margin Gem cookstove.  The Margin Gem is actually the second wood cookstove that I have purchased new, and I want to share with you what factors I considered when choosing a cookstove.  As I've read other wood cookstove owners' accounts of how they decided to purchase the various cookstoves that they own, I notice that each is unique.  Our story is too, and perhaps someone will benefit from reading about it.

I took the following things into consideration when making my choices.  They are not necessarily listed in order of importance.

a) Cost.  Unfortunately, this is always a consideration.  When you consider this, though, think about what kind of return your stove will potentially give you.  We don't have to pay for our firewood.  As my brother says, "Jim can't burn enough wood to keep up with the dead trees around here."  Therefore, other than our time (which would be spent cleaning up the tree mess in some way in any event) and woodcutting supplies (chainsaws, chains, saw fuel, sledge hammer handles, etc.) it costs us nothing to operate our stoves once they are installed.  Thus, our cookstove considerably cuts down on our use of propane for heating and cooking, and now that the Margin Gem heats our hot water, we have additional savings there.

I've never heated our house entirely on propane during a winter, but I think that a conservative estimate (given our high-efficiency furnace, the size of our house, and its draftiness) would be that we would burn a thousand gallons of propane during a normal winter if it was our sole source of heat.  That means that it would cost us at least a thousand dollars to heat our house for one season if we used only propane.  When you look at the cost of a stove and prorate what it will save you in heating expenses during its useful life, that can change the way you look at your initial investment quite significantly.

b) Location.  You have to consider where you will be putting your stove quite carefully; then choose a cookstove that will fit there.  However, you must also figure in the clearances!  This is so important!  The measurements of a stove are not a representation of its true footprint in your house.  Clearances can be reduced with appropriate materials, but those materials will have measurements of their own.  Measure, research, measure!

The clearances on woodburning cookstoves vary drastically because of the different designs that are out there.  If you are planning on purchasing a true antique cookstove, you can pretty much plan that your home insurer is going to ask that 36" of space be between your cookstove and any combustible surface, and 18" of space will need to be between single-walled stovepipe and anything combustible.

c) Looks.  This might be the least of many people's concerns, but for me this is an issue.  I know that many of the new wood cookstoves that are on the market are designed to keep costs low for those who want a functional and efficient stove, but I also want one that is at least somewhat traditionally pretty to look at, too.  Sorry.  I can't help it.

I'm still reconciling myself to the more modern look of the left side of the Margin Gem.  I prefer the antique look of the Oval's left side, but I still feel that the Margin Gem was the right choice for us.

d) Purpose of the Stove.  What are you planning on doing with your woodburning cookstove?  If you are only going to be using it during the occasional power outage or for weekend ambiance, your approach to choosing a stove can be quite different from what it would be if you are planning on using your stove as your main--or even sole--means of cooking.

Before we purchased the Margin Gem, I talked to an Amish man who owned a Gem Pac (slightly smaller and less ornate sister of the Margin Gem).  The man whom I was talking to and his wife were planning on building a new house in the near future, and when I told him that we were thinking about replacing the Qualified, he offered some interesting insight.  He said, "My wife would like a Margin Gem for the new house.  She told me that she wants a cookstove, not a heating stove that you can cook on.  My brother's stove has to be so hot to get the oven up to temperature that it will drive you out of the kitchen before you can bake anything."  I'm glad that we don't have to be sweltering just to bake.

e) Oven size.  To me, this was a top priority.  I knew that there would be considerably less joy in using a wood cookstove regularly if I felt like the size of the oven was preventing me from using the baking utensils that I was accustomed to.  Thus, as a twenty-one-year-old, I pored over the specifications for the ovens in the cookstoves which were available and affordable at that time.  Then, with a yardstick, I drew lines in the pile of my living room carpet which represented the width and depth of the ovens.  Next, I retrieved all of the biggest baking utensils that I had: my largest cookie sheet, the biggest jelly roll pan, and my largest enamelware roaster.  I placed them on the floor to see whether they would fit in the oven.  When I got to the roaster, I also put the lid on it and held my thumb on the yardstick to represent the height of the oven to make sure that I would still be able to use it with its lid.

The fact that the oven on the Qualified Range was the largest in the stoves that were in my price range had a great deal to do with my choosing it.  I went through the same set of tests with the same cookware before deciding to purchase the Margin Gem, too (only I didn't draw in the carpet--I guess I'm growing up).

f) Ease of fueling.  Perhaps this wouldn't be as much of a factor if I hadn't started out with the Qualified range.  The Qualified has a coal feed hatch on the left side of the firebox, a door in the front of the firebox behind the white cabinet door, and removable lids, "T", and cast iron frame above the firebox.  In other words, if you have a piece of firewood that is the right size, you have all kinds of options for getting it to the fire.  The best thing about fueling the Qualified was that unless you had such a large piece of wood to add that you had to lift the "T" or the entire cooktop frame, it rarely let any smoke escape into the room. 

Several of the new stoves on the market today do not have very many fueling options.  Some can be fed only through the top.  This seems impractical to me, especially when you are in the throes of canning.  The last thing you will want to do is to move a large canner full of jars away from the firebox in order to refuel.  The Margin Gem has a larger front door on its firebox than the Qualified, and I find that I feed through the front much more often now.  I still tend to favor feeding through the front cooktop lid, however.  I think this is because I don't have to bend down to see what I'm doing.  For feeding large pieces of wood, the Margin Gem is equipped with a handle which raises the entire section of cooktop above the firebox.  I imagine that we will use this more often in the winter, but we haven't used it much right now because a great deal of smoke hits you in the face when you open the stove this way.

the night we were hooking it up.  The pic shows
the cooktop and front door open, comprising two

g) Cooking flexibility.  When we ordered the Margin Gem, the sales representative tried hard to convince me to opt for the Flameview.  I think his words were that it was "the perfect stove."  Indeed, it has features that I think we would have liked, but two things prevented me from choosing it.  First, it has a greater heating capacity than the Gem.  This would be great if we only used the stove in the winter time, but since we have an additional heating stove to help heat the house in cold weather, why put up with extra heat when we just want to cook in the warmer seasons? Second, the Flameview is only sold with a solid cooktop--no removable lids.  I'm far too accustomed to being able to remove a lid or lids and grill directly over the fire or speed the cooking of something.  Nancy can attest to my occasional inflexibility, and I didn't want to give up those options.

If you are a wood cookstove cook, please comment and share what things you considered before making your purchase.  My hope with this post is that it will help wood cookstove shoppers with their considerations before making a purchase.  No matter which range one chooses, it will become a major part of one's home, so careful consideration is a must.

Some readers may still be at a point in the process of choosing a stove where they are trying to convince themselves or others that a woodburning cookstove is a good idea.  For information about why we chose a wood cookstove, visit this post.
