Combustion air requirements
Without getting into the other air intake possibilities...code requires that the outside air intake ducts be covered with no less than a 1/4" screen. My concern is that there are a lot of bugs, mold spores, etc. that are much smaller. There's no way to fit this with a filter?
I bought a foreclosed house and the bank had just installed a brand new power vent water heater. Unfortunately, as I would like to seal up the house I am worried about providing combustion air to this appliance. A direct vent water heater would have been preferable but I'm not willing to shell out the cash to replace an 8 month old water heater.
