Having purchased the camp stove and now wanting to use it inside the camper annex, we had to come up with a way to fit the chimney through the annex roof while preventing the canvas from burning. This job was carried out at our home in Townsville before we started our journey.
After a short research session, these normally happen at night time with the help of a few liquid refreshments, a solution to the problem was found. Bunnings offered the right part for the job. Our local Bunnings didn’t have the item so we had to pick one up when we visited Brisbane.
Step one. Work out where you would like the stove sitting inside your annex to make the most of the warmth it provides. Ensure that it will have ample room away from the annex walls to prevent the canvas from burning.
Step two. I made a big square clamp for the underside out of 2 mm aluminium checker plate. This was made to size to fit neatly inside the base of the Dectite Silicon Flue Seal. Holes were drilled through the seal and underside clamp at spacing to ensure a positive seal.
Step three. Mark out on the underside of the annex roof where the chimney will be fitted, ensuring you have enough room for the seal to fit correctly and the chimney is away from the annex walls. Place the seal against the canvas and mark out the holes for the small bolts or pop rivets you want to use. I opted for small stainless steel bolts with flat washers and Nyloc nuts. Also mark out the inside of the underside clamp. This should be a square.
Step four. Using your trusty Stanley knife or scissors, cut the canvas square out and also punch out the holes for the bolts/rivets. I only cut three sides of the square so I could tape it up again if I took the flue seal back off.
Step five. Place the flue seal on the topside of the canvas and the square clamp on the underside of the canvas, secure the lot together using your bolts/rivets. You may choose to put sealant underneath the flue seal to prevent any water from leaking in.
Step six. Now you just have to cut the flue seal so the chimney fits snugly so rain won’t get between them.
We had to get another section for the chimney made so it would sit high enough out of the roof. If we do not have the camp stove in our annex and it starts to rain we just put a tin over the flue seal to stop any rain coming through.
This solution worked for us as we always use the “measure twice and cut once” principle. This is only meant to be a guide as I would expect people to have a bit of nous when carrying out their own work. If you stuff it up, don’t blame me.
That’s all for now folks as I have a few drinks to catch up on. Oops, I mean research to do.
