My Solo Innova Manual calls for a six inch outside combustion air opening. The opening will be on the outside wall of my boiler room, five feet from the boiler. My boiler room is roughly 8' by 10'. It has no windows and only one door leading directly outdoors.
I came across a product, an Aldes spring loaded backdraft damper, I thought might help limit cold air infiltration into my boiler room through the combustion air opening when the boiler isn't running. Here is it's specs: http://www.ntsupply.com/files/products/BDD_Backdraft_Dampers_Brochure.pdf. The specs say the damper will begin to open when there is between .04-.08 w.g.
I don't know anything about w.g.'s and I don't know how to read the chart in the above link to know whether the damper would open or not when the the induced draft fan on the Solo Innova is running. Does anyone know what w.g.'s are and could figure from looking at the above linked chart if this damper would allow combustion air into the room when the fan was running.
I was thinking of maybe getting the 8" version (on the principle of bigger is better) . I'm trying to avoid the use of a motorized damper or louver, fan in a can, or the more expensive Tjernlund Air Inforcer units. I was thinking this damper might be an alternative to a cold air trap, or other low tech solutions to limit cold air infiltration when the boiler isn't running. What do you think?
The damper pops right into the end of a standard round duct. It runs only $32.66 plus shipping at http://www.iaqsource.com/product.php/american-aldes/99-026/?product=173855#pr-header-173855. I am hoping it will do the trick. Any advice would be appreciated. Thanks.
