does comb. air high and low vent need to be on same wall?
the wall closest to the furnace and water heater can only allow for a low vent. the high vent will have to be about 5 feet away on a different wall. Is there a scientific air flow reason that the high and low vents need to be on the same wall? Like is there some type of Newton circular air theory? Or is it just high and low needed for the room in principal?
(for a background both my furnace and water heater are POWER VENTS)
You pros can laugh at this DIY-er, while remodelling my basement and insulating i will say this combustion issue is the biggest gaffe/screw up i have ever encountered in all my home remodeling.
But, can cause some problems being on opposite walls.
Such as putting enough pressure in the room, that the pressure switches of he furnace and water could close, when the units aren't on, and cause a lockout.
OH I'M ALL TOO AWARE OF THAT PROBLEM! It happened to me already. Furnace shut down with "pressure" lockout code. After a weekend of insulating my new remodelled basement, complete with solid core door (that replaced the 1970's louvered door which stupid me thought was "too ugly".) I need to cut the high/low vents from the mechanical room (11X15) to the newly remodelled basement rec room. My plan was to cut the low vent in the wall, but the high vent i wanted to use the joist space opening to a different wall. (which i had previously stuffed with insulation.).
