Installing a stove above a furnace

[action95]

He All, Has anyone ever put an oven/range above a furnace? I’m reading that this can be dangerous because the furnace can suck the gas from the stove down towards it at the air intake, but I feel like this is something that you see in trailers all the time. Am I missing something?

Our '74 and our '93 both have the range above the furnace. I'm not sure where you read about it being dangerous. If it were, hundreds of thousands of rv's would be dangerous.

Our furnace draws combustion air from outside.

I suspect darn near all of them except the catalytic type heaters. (Which I would never choose for inside an Airstream. Let the opposing opinions fall where they may. I prefer my exhaust gases outside my living space. )

There are TWO air flow systems in a furnace. 1: Combustion air. Air needed for the flame is drawn from the outside and exhausted to the outside. 2: Room air. Cooler air from the room(in this case the trailer) is drawn into the heat exchanger where it is heated and exhausted back into the room.
These two air systems are sealed off from each other.
So no matter where the stove is in relation to the furnace, the worst that could happen is, if the furnace blower (which circulates the room air) is to strong, it could suck the flame towards it. I have seen this happen in homes where the flame moves towards the range hood exhaust fan.

Indoor Return air to the furnace is near the floor in every RV I’ve had including my AS. My stove and oven are right above it. The stove and oven heat rises so the odds of this heat getting to the heater return air intake is slim and if any does make it down there it’s mixed with room air by then sufficiently to the point that risk is negligible.

FWIW, propane is heavier than air and settles to the floor anyway. That is why propane detectors are located near the floor. I wouldn't be concerned because the fan only sucks air into the heat exchanger to be circulated through out the trailer. As stated already, that is separate from the combustion process.

Thank you for all of the responses. Just to clarify this is the warning that I read with my stove that made me start this thread. It sounds like as long as I build walls around the oven/range on all sides I should be ok.
