I installed my Englander nc 30 today. I ordered double wall stove pipe, but received single wall. I was to excited and took the day off. So I decided to use the single wall. Also because I thought I had the hearth room. Englander says 16" from combustibles, which it is. How ever Metal fab stated 18" from combustibles. From the center of the pipe it is 18" from the drywall. Is that sufficient clearance?
 
Measure from the pipe to the wall , if 6" pipe your 3" too close. sorry.

Single wall pipe needs to be 18" or more from the nearest combustible. It throws off a lot of heat. Return the pipe for double-wall.
 
I was afraid you would say that! But expected it. Can't return it I lit a fire. Thought the wall was a little warmer than I would like. Then went and reread both sets of instructions.
 
Depending on how the stove is connected you may have the option of installing pipe heat shields to reduce clearance. Can you post a shot of the stove installation?
 
This isI from the englander installation guide."
The black connector pipe should be 24 gauge steel and sixteen inches (16.0”) from a combustible wall or eighteen inches (18.0”) from a combustible ceiling. This clearance can be reduced by using double wall or single wall stovepipe shields.

Begreen, as always thank you for your infinite knowledge and quick responses.
 
I have a comment that doesn't have anything to do with this install but we just installed a regency 2400 and in their install manual it says you only need 17.5" to the center of single wall pipe we put double wall in anyway even though the manual said we don't need to but what do you guys think about that situation?

I think it desirable to err on the side of caution, nevertheless.
 
Go by code and the pipe mfg. directions. Both say 18" for single wall pipe.

Again this does not apply to the nc 30 but in regencies instructions http://www.regency-fire.com/Files/Manuals/F2400-918-154.aspx on page 4 it says with air mate 17.5" to the center of the pipe for single wall. I didn't feel comfortable with it and didn't have the room on the homeowners hearth to get 18 so we put in double wall just wondered what every ones opinion on it was. I agree with tenn dave and went on the side of caution

17.5" to CL is possible if there is a pipe shield so technically it is not entirely wrong.
 
Would the OP not have to install double wall at the ceiling connection? I can see a shield working along the length but I'm not sure how he is going to shield the single wall from the drywall in the ceiling. Maybe but just not familiar with single wall installations.

The pipe shield just goes all the way up to the ceiling box. Clearance to combustibles can be reduced to 9" with pipe shields.

It says absolutely nothing about a protected wall and i just looked at the nc 30 manual and it clearly says 16". I personally still would go to double wall under 18" but according to the manufacturers instructions (which override code) for the englander 16" is fine. Correct me if i am wrong but I cant find anything in either manual saying those clearances are for a protected wall
 
You all know way more than me but wouldn't the pipe mfg. instructions over ride the stove mfg. as to how far the single wall must be from combustibles?

The black connector pipe should be 24 gauge steel and sixteen inches (16.0”) from a combustible wall or eighteen inches (18.0”) from a combustible ceiling. This clearance can be reduced by using double wall or single wall stovepipe shields.
Is this misleading or am I misinterpreting.
 
I think there is often a lot of confusion on this topic...definitely not the first time I've read a conversation like this.

Misleading in my book.
 
There's the regulations, and then there's what I would do for peace of mind. For me, the regulations are the starting point. Take the most conservative and start from there. No question.

In my case, I just modified my insert installation with a blocking plate and now I'm getting more heat from the stove coming into the room. I have a painted wood mantle 27" above the stove and while the installers originally said I didn't need any protection for it, I'm going to add a simple metal shield to direct the heat away from it. A two inch gap between the mantle and the shield should help keep the mantle cooler... I don't care whether code says that clearance is okay...I'm not comfortable with it.
