Airflow messing with range flames

Wow, that’s quite something. 

 

I guess that’s why test and balance is important.

If a building has any form of class B chimney, it has to have a nuetral to slightly positive static pressure. Carbon monoxide is nothing to fool with.  That’s why we are seeing interlocks on kitchen equipment now for ventilation proofing. And the popularity of draft inducers on fired equipment like Hot water heaters, boilers and furnaces. External heat sources like roof tops are now going to then to prevent combustion chamber crack from leaking CO.

makes sense, it can be pretty lethal if allowed to go unchecked. 

 

I like the pressure sensing switches that have to feel the airflow before allowing the unit to fire, those make sense, they are easy to test.

There are some locations that are starting to interlock the cooking line to the vent hood.  No hood, no gas

Makes sense. I Guess that’s when its really bad where your exhaust hood goes down.
