Pellet vent pipe...10/2 rule

[alexei27]

Hi there...

I have Summers Heat...love it. This will be season number two on Long Island. Here is the issue. Right now the top of the vent pipe is right at the height of the bottom of my roof (basically near the gutter). I need to increase the vertical height of the vent pipe about 6-8 ft to meet the 10'/2'/3' rule. IMO this will look stupid, but I don't think I have another choice (I cannot move the stove).

I know I need to go over to 4" pipe above a certain height...but I am most worried about the 6 or more ft of pipe that sticks up over the corner of the house.

Has anyone faced this? Any photos? I assume I need some sort of brace to hold up the pipe in strong winds?

Thanks!

When I put in my stove they told me that that rule does not apply to pellet vent ,and that 18in was lots . How ever if you do have to do that you can use the same brackets and braces that are used for gas chimneys . You will need two braces .
I would check with building inspector ,if you only go 18 in you won't need a brace.

I agree mine was professionally installed and it doesn't meet that rule.Best to check with local code.

Check your owner's manual. It will tell you how & where to terminate
your pellet vent. That's where the building inspector will look first.

I'm not a smart about pellet stove person so could you explain the 10-2-3 thing. I don't know what that is? bjr23

Alexei, I'm not familiar with the 10/2/3 rule that you mentioned, but as far as I know, pellet vent has to just go a minimum of 2' above the roof, regardless of where it exits the roof. Maybe explaining the rule you mentioned will help us understand better.

As for the 4" pipe, that is only needed IF you are at more than 5000' altitude (not applicable to you), OR if your EVL is more than 15.

The 10/2/3 rule is from the natural drafting wood stove world. The rule states that the top of the chimney must be 2 feet taller than anything within 10 feet and must be no less than 3 feet above the roof penetration. The entire basis for this rule is that the natural draft is affected by surrounding roofs and other obstructions when the wind blows.

Pellet stoves are forced draft so aren't bothered with silly things like natural draft.

Thanks for the replies...good description of the 10/2/3 rule also.

Unfortunately it does apply here (Town of Brookhaven Long Island, NY). I was mainly looking to see if anyone had a similar setup (vent pipe installed on the corner of the house...near a low point in the roof).

Right now...I vent out under the roof line...and have never had any problems. Its kind of annoying but I guess I need to do it.

I think I do go above an EVL of 15 if I go to the "legal" height above my roof.

Personally I would arm myself with all the documents I could find, owners manual, industry recommendations, letters from stove stores and manufacturers, fire safety code standards and every a forgive me from mom. Have a sitdown with the code inforcement folk and help change the code, or at least get a variance based on the evidence. You could end up being a hero and making the top ten most wanted list at BurningIssues.

A bag of duoble fudge brownies might help too, if they are homemade.

How did you get these guys on your case ?

Made the mistake of applying for a permit. My homeowners ins requires that the stove be certified by the town. Hence my long dark road...

I had to do that as well . I spent the first week trying to find out what they wanted . They didn't know . So I did what I thought would satisfy them .I laid awake for three nights waiting for them to come
and inspect .When he did come he just looked at it and said that's good . Didn't measure any thing ,never went up on the roof or anything . Sounds like you got the guy I was expecting.
You are going to have to change to 4 in for at least part way . You can probably just add to where your existing vent is . You will need to brace it ,but can get that from the dealer .It is just two galvinized angle irons and a clamp ,they likely have a kit . Don't make the mistake of ordering it on line like I did . I started in Oct and am still trying to get that straightened out .I still have a damaged pipe sitting here waiting for them to pick up .

My town simply requested a copy of the page in the owners manual that showed my type of exhaust install, and what the clearances had to be on the hearth pad. When the inspector came, he eyeballed it, looked at the pages from the manual I supplied, and said "your good to go"......signed the permit and I was done. But........every place is different.

Excell, as for him not ordering online, I somewhat disagree. I have dealt with 2 places, one of which is Eric at Kinsman Stoves (Hearth.com member, great guy & great service...had my part in 5 days even though he was away on business for 2 of them), and also have had great service from DynamiteBuys (www.dynamitebuys.com). They had my parts to me also in 3 days. Both places have great prices on pipe, and if you mention to Eric at Kinsman that your a Hearth.com member, I'm sure that will help some too.

 

[Excell]

I have had many good experiences ordering on line ,but this one was a night mare . I think that if I will let the home town boys screw it up for me ,then when I need to talk to them I can .
I just can't see my self ordering from ventpipe .com again .

alexei27, have you seen this code they are reffering to? My guess would be they don't even know what they are doing. They prob know the wood fireplace 10/2 rule. Think... hmm "wood" pellet stove, must be the same thing right? Wrong.

Possibly all thier code mentions is "solid fuel" appliances, in which I suppose pellets would qualify for that.

I would do as littlesmokey says.

I think every pellet install manual in the industry simply says 2ft out of the roof, done.
