Grand River 33TBOK Comfortline

[Slipper]

Good Afternoon!

I have a 2021 Grand River 33TBOK Comfortline, that was delivered in May of this yr. This past weekend, I had an issue with the hot water tank, with it looking like it caught fire. I put a call in to my dealer and they advised me it could have been a spider nest, which it could very well be. My gut though is telling it it could be something more. It ran without incident Wed - Saturday morning. Saturday afternoon, it literally looked like it caught fire, with soot all the way up the side of the trailer. Pics attached.....anyone know what else it could be?

Your trailer doesn't appear to be a Forest River product. Who makes it?

It's A Grand River, which is made my Forest River. I'm Canadian, so not sure if that makes a difference for what is available per country.

It looks like (from the far away pic) that your air intake collar needs to be adjusted. When you loosen the screw, it should slide back and forth. Make sure the flame shoot is clean and adjust the collar so the flame is nice blue in the center.

Thank you. The tech is looking at it tomorrow so hopefully he sees that

I just searched all the Forest River line and sub divisions and could not find a Grand River, maybe just in Canada???

Possibly. All my paperwork for it is Forest River, warranty and roadside assistance all on forest river letterhead. More than likely just a Canadian branch of Forest River

It may be a clone of another FR brand line, made for a particular large RV dealership. I suspect this because there is no such brand as Grand River in any of Forest River Incorporated's divisions.
FR Inc has done this for numerous large RV chains. They take a particular brandline and put in different outside graphics and interior decor. The floorplans are exactly the same as the original FR brandline's models.

Normally, the air flows in the bottom vent, gas-air mixture ignites, air and gas are drawn in the intake tube, combustion takes place near the tank, and the hot burned gases are exhausted out the top port. Convection (hot air rises) causes the flow in this direction.

If the channel is clogged with mud dauber nests or spider webs (or possibly there is a strong wind), the flow will be in the reverse direction. This is not a clean combustion, won't heat the water well, and will put burn/scorch.carbon marks on the cover by the lower port and possibly up the side of the RV. The fix is easy. Just use compressed air (an air compressor, not one of those keyboard cans) to blow out the entire path.

My grill has done the same thing.
