outside air ?

What would be acceptable to me would be a PVC pipe, painted brick red with matching 'mortar color' stripes to blend it in with the brick.. or just paint it flat black to match the flue and stove..

If you have a basement you can run the pipe from underneath and up through the base.

It's sitting on the cement basement floor already. Thanks for the ideas but I think I'll just use my "window open a crack" which works fine.

Back to one of my initial questions. ( unless I missed the answer)

Is "additional" cold air coming in, ever an issue ?

I'll probably go with 2 or 2.5 painted PVC.

Thx, Mossy Beard

Any 'additional air' will be coming in right next to the hot stove. So you won't notice it.. your house currently has lots of 'additional air' coming in.. from various windows, doors, and cracks/leaks. These are felt as drafts and cool the area around the leak..

So no, any addtional air coming in will be moderated by the stove's heat and you will be more comfortable.

LSFarm your advice has created yet another project. I just finsihed installing my outside air vent. I used a 3" aluminum flex pipe. It was an easy install. The direct vent unit is very close to the opening for the combustion blower but I was still able to get it into place. I didn't seal it as u suggested. Now I have to locate a screen that isn't too fine to keep out little friends.

I was thinking of adding an outside air line to my combustion blower on my LL Econo stove. I was wondering if there was a min. distance the intake should be from the direct vent. It seems there should be because of CO.

paGuy: Great question - My stove is a corner install so I put the air vent on the opposite wall so it's not anywhere near the exhaust. I'd say no closer then 5ft.

What's everyone using to terminate out side, on the block face ?
I was looking for some kind of "manfactured vent cover".
I suppose I could just let the pipe run long and band a screen on it. :)

Is condensation( in the pipe)ever a problem ? re: warm to cold , et.al.

For the aluminum pipe I bought at Lowes they sell an end piece to keep out little animals but insects could still get in.

How small of a pipe can you get away with for using outside air and shouldn't it be well insulated to keep any cold air from escaping before it gets to the fan? Does the insulation and tape need to be at a certain temperature rating since it's so close to the stove?

I'd use a minimum of a 2" pipe.. larger for a big stove or boiler/furnace. There is no need to insulate it.. yes the pipe will be bringing in cold outside air. but there will be very little if any condensation on the pipe,, indoor humidity levels are very low in the winter..

PVC, or aluminum flex pipe, or similar will work fine.

The flex pipe I bought at Lowes was 3" ISD.

I finally have the time to upload a pic of the pipe for outside air.

Trader,

Your vent looks like it has to work a little extra harder then it should to get the exhaust out of the house.
