New Range Hood - robbing combustible air???


Hey Gang,

I asked this in the appliance forum but it was suggested it would be better to ask this here.

We are going to install a new range hood in our kitchen. The ones we are looking at are about 600 cfm. It is likely more cfms that we need.

However, I have been told we don't want to rob our furnace of combustible air.

We have a high efficiency furnace. I thought most of the combustible air is brought in from the outside.

Do we need to be concerned with the range hood robbing combustible air from the furnace?



Thanks,

If you have a true high efficiency furnace with no chimney/ and uses 2 plastic venting pipes to the outside and no chimney for a gas water heater you are safe. If you have a chimney for the furnace and/or a water heater then you may need a combustion air pipe. If it only has 1 plastic pipe then it takes combustion air from the house and a comb air pipe may be needed. Did the snow you had last week melt? Crazy weather. LOL. I lived in Calgary for awhile.

Hi Yuri,

We didn't get much snow up here in Edmonton, but Calgary and southern Alberta got a bunch.

Yes we do have a High efficiency furnace with the 2 plastic pipes. So we are good there. However, our hot water tank is the traditional exhaust up the chimney type. I never even thought of that being an issue.

I will check the basement, cause now that you mention it, we have two fresh air intakes in the basement as well. One ends right beside the furnace and hot water tank about a foot off the floor. I don't know where the other one goes. Maybe those are my "combustion air pipes".

I will investigate and report back.

Thanks Yuri.
