Advice on Range Vent w/ external blower in High Snowfall area

BrightFutureFoodsSeptember 16, 2011

I'm looking at employing an external blower on the roof to vent my very powerful 48" Capital Range. My concern is that we live in an area of Vermont where 2.5 feet or more of snow on the roof is not uncommon. The roof is pitched but not overly steep so it may hold snow for a while before sliding.

What is generally done to ensure that the blower and vent will not be obstructed by snow?

Any advice you can provide would be greatly appreciated.

An in-line system could probably be used instead if necessary, but still concerned about the vent pipe (likely round 10" duct).

can you mount the blower on the side of the house instead of the roof?

Thanks for your reply Julie,

My range will be located on an interior wall. Venting to an exterior wall, while not impossible, would be difficult, particularly given the low rustic wood beam ceiling in the kitchen. I only have enough room for about 25" of hood and duct to the ceiling, so just making that turn with 10" round duct to vent sideways would take up most of that.

I have to believe people have roof-mounted blower systems in snowy areas of the Country???? I can't seem to find information about this on the hood or ventilation manufacturer websites.

Has anyone had experience with this?

I suggest calling a mechanical contractor in your area. Look for one that advertises residential-light commercial.

I would be concerned more about ice build-up with repeated melting and freezing than snow blocking the vent.

Another good suggestion, Julie. Having a hard time finding someone in this area with that particular expertise.

Ionized...I agree. Wondering what people do with that?

I really don't know, but I have to hypothesize that the air has to exit the vent structure sideways rather than directed down toward the roof surface.

Another method comes to mind, but I don't know if it is practical. You would have to mix outdoor air with the exhaust air to reduce the temp. That would have its own problems since it would be a snow machine.
