Mark II Cert of Occ with Inlet Air Discussions

PostBy: Uglysquirrel On: Wed Sep 03, 2008 8:38 pm

The Mark II and it's owner are real happy with the Town approval today. The Inspector was pretty top shelf and asked how the air infiltration was into my basement. He agreed that between the sill leakage and hatchway leakage I was fine (therefore the approval) but he did
suggest that it's always good for newer homes to provide a more direct air path from the outside to the stove air inlet.

He said in informal discussions that a good setup is likely two snow/rain sheltered 4x4 ducts to the outside(near sill plate) with insect screens, one of the ducts leading to the basement floor and one ending near the ceiling (likely a air density consideration). The exits of both these should be reasonably near the stove. He recommended smooth ducting vs the corrugated (clothers dryer) for better airflow. This guy knew his stuff. He said there could be some sort of air adjusting door on these if I wanted, we both agreed the amount of cold air coming in would be small compared to the BTU output. There is some recommended code that suggests this sort of configuration though we did not discuss that in any detail.

I'm not sure if the above configuration meets any code, please do more study if you want your system to be to code as this inspector and web info above is based on informal discussions.

He did like the nearby CO and Smoke Detector with the expiration date hand written and new battery change dates on the front covers with the manufacturer's manuals stapled on the drywall . (Hint for you newbies like me going for a Certificate)

Beyond that he noted a lot of people are doing pellet approvals though I was the 1st coalie this year. That is fine with me.

For your info,hope this helps some of you with tight house infiltration issues.

Do any of you see any issues with this general configuration in high wind conditions, etc?

Comments appreciated.

Take a look at this discussion: outside air ?

I agree completely with your inspector.

Interesting, LSFarm, your link noted 1 sq. in for every 4000 btu, 4 x4 is 16, 4000 x 16 is 72,000 BTU which is the rating on the Mark II. Wow!

And thank you for that link.

I feel safe in my Town with this inspector!
