Selkirk Metalbestos chimney question.

PostBy: TonyG On: Sat May 03, 2008 6:27 pm

I'm going to install a EFM 520 in my garage and pipe it to the existing oil burner, had enough of this fuel oil BS, but will keep both for now.
This location is on the opposite end of the house from our chimney. I'd prefer not to build a masonry chimney, we'd rather go with a stainless steel Selkirk Metalbestos type pipe inside the garage for just over $1,000.
This chimney will go straight up to the rafters and through the roof. Distance from the floor to the roof penetration is 13'.

1st, are these S.S. double walled insulated pipe ok for this particular application?
2nd, how far must the pipe and cap protrude out and above the shingles?
3rd, opinions on Selkirk pipe from those on this board would be of great help.

Thanks, Tony

Hi Tony,, the top of the chimney should be higher than the peak of your roof if it is within 6' or so of the chimney... You also need to consider trees blocking airflow,, and if the rest of the house is higher than the garage, it could cause downdrafts over the garage if it is in the way of the prevailing winds.

The SS chimneys are very good, but are not going to last forever,, a masonry chimney will last just about forever,, but are a lot more work, but the materials are less... I put up my own masonry chimney.. it wasn't difficult,, just work... I was able to borrow scaffolding, and use the front bucket of my big tractor to get enough height to set the last few block... interesting operation.

Hope this helps... Greg L

Hi Tony,

I am not familiar with Selkirk manfactured pipe but if their warrenty covers coal fired appliances you should be ok. Not all stainless pipe is created equal.

Tony, Selkirk makes some good pipe and they list it for use with anthracite coal. I used selkirk JSC pipe on my install and it performed well. A brick/clay chimney will last longer but I am hoping to get 15 or so years out of mine. When the stainless chimney goes bad it is usually the first 2 or 3 feet from the top where the moisture reacts with the ash and you can just replace the bad section. You must also clean the chimney every year at the end of the season. As for height above the roof line, You need a min. of 3 feet above where the chimney penetrates the roof and a min of 2 feet above any part of the roof that is within 10 feet of the chimney.

I just looked and metalbestos is not what you want!
The selkirk website says it is for gas vent and the inner liner is made from aluminum.
You want the supervent(sold by Lowes) or the super pro. Both are stainless inner liner and outer shell.

Greg, Steve and Rick,

Thanks for the replies...I'll keep looking before I spend the money. I'd really prefer 316 S.S. on the inner liner.

I beg to differ, Selkirk makes many types of pipe. Here is a link to the stainless steel Selkirk, rated for all-fuel which covers coal applications.
Ultra-Temp is designed for All-Fuel applications - with a Stainless Steel outer casing. Sold through professional installer markets. Sizes: 5", 6", 7", 8", 10", 12", 14". Insulation: 1" Solid Pack, Listings: UL-103 HT

I have used this pipe since 1979 with no complaints in a seaside environment.
Gambler’s height numbers are correct.

I'd guess that most SS pipes are rated for coal, but check to be sure.

A new law in Maine, I wonder if others will follow. I hope not, it seems pretty dumb to me. The law: All new boiler instalations must have a Stainless steel liner in the chimney.

My mason chimney is about 3 yrs old. By law I have to put a SS liner in it when I put in the coal boiler. 'Taint gonna happen! But, if I hired a licensed person to install it, it would have to be lined to the tune of $2,500? Ouch! Dumb dumb dumb.
You should see the pissed off people that are changing from electric heat! They hire a mason to build a new chimney. He does. They now hire a boiler man to install a new furnace. He get's there and says "I cannot install a boiler until you have that chimney lined".

I have a masonry chimney for my coal stove that is about 25 years old & is clean as a whistle inside. I originally looked at using a metal one but found out they wouldn't last due to corrosion with coal fires. Would any metal chimney give you the life expectancy of a basic masonry one? (I doubt it)

Going with a basic masonry chimney isn't what I'd like here, the home has brick and I can't match it no how. It would be relatively inexpensive to do so(friends) on the masonry side, I just didn't want it to look like a horses arse. Stucco on the outside is a possibility, we haven't ruled it out just yet.

If you go to Selkirks web site and look at the different chimneys they make It is kind of confusing with the metalbestos. I liked selkirks old web site better because they gave you all of the specs including material and thickness.If you go with a metal chimney just make sure it is stainless inside and out. And be sure to find out what grade of stainless it is. I don't know if any company makes a chimney with 316 stainless but I know selkirk uses 304 stainless for the inner liner. I hope mine lasts as long as CapeCoalers has. You can get the selkirk supervent at Lowes for $72 for a 3ft section and it is all stainless 304 inner liner with a 430 outer casing.

Agreed Selkirk’s web site is confusing. The SuperVent is for the Big Box/DIY market and the Ultra-Temp Platinum is the contractor/installer version. They also had specifications that differed on the boxed item, the web site and a pamphlet! We went to the source and cleared it up but it underscores the fact you should always verify your information from several sources before committing to a project. My previous post has a link to a PDF which has the phone number to Selkirk technical support.
The Metalbestos chimney that went up in ’79 was actually taken down in 2000 for a remodel. The tongue/male part of the connection had begun to rot but the inner pipe was still fine. The pipe was maintained properly, was used regularly, had wood and coal burned in it, and had served its purpose for 21 years.
Masonry chimney properly built and located is almost always the best choice. The metal chimney, under certain circumstances, is sometimes the better choice.
You could BRICKMASTER it.

A smooth stucco finish would be ok and you could color it as you wish. Most stucco finishes on chimneys here are white, some with a black trim ring to identify if you were Tory or Whig.
The liner issue is really due to moisture and a lack of ‘excess heat’ to carry it all up and out of a masonry chimney due to the higher efficiencies of ’modern’ appliances. The liner contains the moisture and minimal excess heat. The moisture condenses when it gets colder and makes a nice corrosive mist/dew inside the chimney.

I have not heard that the liner in Maine has to be Stainless Steel. I thought it was a matter of putting some kind of liner in the many old chimney's that are just brick. I will check my plumbing & heating guy. I do all my own work also but it is hard to keep up with code changes when you are not involved in that particular trade.
I use Selkirk but have not been burning coal for long enough to have an opinion about its performance. I think that you would have to be nuts to build a masonry chimney for burning wood, oil, or gas. The coal seems to be the question. I have taken Selkirk down in houses that have been using it for wood for over 25 years and put it right back up. No repointing and no leaks around the flashing and no water running out of it in the basement. As far as the cost goes, if I get 15 years out of mine I will just put up another because it will only take about 2 hours to take down and replace.

When I installed my boiler last summer, I decided to go with an insulated metal chimney system. I had an chimney on my handfired coal stove from a company called Security. Ive burned both coal and wood for over 20 years with this pipe, and its still in good condition.

The new chimney pipe if from Simpson, their Duratech all fuel pipe. It is rated for wood, coal and oil, here is a link: A chimney sweep friend had reccomended this pipe, he could get me any pipe I wanted, but this was the pipe he normally installs.

One of the advantages of the insulated metal chimneys is their ability to hold a draft better in warm weather, since they loose less heat to the exterior.

Security pipe is by far the best pipe. It has the best warranty, the best construction, and the best design. Selkirk used to be good, but they have really gone down hill (they are at the bottom with Amerivent & Duracrap). I own a hearth store and run a chimney sweep business, and I only use Security pipe. You may pay a little bit more but it is definitely worth it. As for Maine requiring liners in masonry chimneys, it is actually a good move with the newer oil/gas fired appliances because they put out so much water that it destroys the terra cotta liners. Coal burning does not do that, and shouldn't need the liner. Talk to the building inspector, he should sign off on it.

Mike, doesn't the Selkirk Platinum Ultra compare equally to the Security?
