Air tightness test and stoves

Airtight Stove

BMD,

We installed two room sealed stoves in our new build. We deliberately did not seal any part of the systems (air supply, stove or chimney) as we wished to test the installation quality from the supplier.

The results, one of the stoves was correctly installed, there was no passage of air between the house and the stove. (confirmed by smoke test).

The other stove had been badly installed and was leaking. Supplier came back, and found some of the system had not been installedadequately.

If we had taped up the stoves for the test, it would still be leaking!

while this is probably what BMD is asking, and worth while doing. don't you think this assessment should be done separately (as in one after the other) to the air-test for part L/ BER compliance?

Yes, this was exactly my point.

In summary, in a house with stoves to comply with the air-test for part L/ BER, the external air inlet should be sealed but the chimney should not.

A separate test should then be performed with the external air inlet open to assess the quality of the installation.

low Co2, you seem well versed on this area, would you agree with my summary?

are you for real, were still on this

in a house with stoves to comply with the air-test for part L/ BER, the external air inlet should be sealed but the chimney should not.

if the stove, is sealed to the chinmey flue (which i presume it is) then yes, that's grand
when your guy is doing this he will go around with the smoke contraption and check for leaks anyway. so unless your builder is super-duper you will have a few area's to address.

A separate test should then be performed with the external air inlet open to assess the quality of the installation.

well yes, this is for your piece of mind and to check if the installer did a good job..

best of luck with it

If you find leaks try to do a proper seal with good detailing and materials- don't just point a spray foam cannister at it
