Furnance exhaust

[Kleva]

Hi!

I Have Atwood furnance. It's exhaust is mounted in the wall right behind furnace. Is it possible to upgrade it. su it will go up ti the ceiling? It looks like more safer, and this exhaust can warm something else in that case. E.g. it is possible to do a wardrobe that can dry wet clothes.

The exhaust is on the outside of the trailer. Having it inside would carbon monoxide you to death. Some trailers have ducting running in the ceiling but to retro fit it would be next to impossible and very expensive

I think the question is, can the exhaust pipe be extended up through the ceiling so it vents through the roof, and can the heat from the extended exhaust pipe be used to warm an interior cabinet.

This is something I would not do, personally. The existing direct vent through the side wall like that is much safer and less complicated from a maintenance perspective. Adding a lot of piping may change the pressure in the furnace which could affect the burn - something you don't want to do unless you're able to talk it through with the Atwood engineers. Running a vertical pipe, you also need to be careful of moisture and intrusion by birds, insects, etc.

If you wanted to be sort of nutty... you could wrap the exhaust with some piping which can handle the exhaust heat, fill that piping with a fluid to absorb the exhaust heat and then pipe into that closet, mount a finned heat exchanger and get some of the benefit you looking for without the enhanced chance of death from CO2 poisoning... Would be easier, safer and a whole lot less expensive than repiping your exhaust.

Unless the furnace had been designed for longer flues to be used, and the installation instructions specifically show extended vertical flue installation, extending or modifying the flue will have an adverse affect on clean combustion and therefore the safe operation of the appliance.
Older UK caravans (travel trailers) used to have vertical flues with the flue routed through a hidden space. The flue would have been secured in the middle of the space as a precaution against heat transfer and the risk of fire. These heaters were designed for the longer flue length.

Just asking for a water leak as well.

Thank's everybody. I think that I will cancel this upgrade or do like mudisfun recommends.
