Hi. New here.....
I recently bought a PE Alderlea to install in my mobile home here in BC, Canada.
Im looking for some DIY tips and information on what I should be looking for, for chimney material.
Northline has a Duravent Mobile Home kit DP-660, but they don't ship to Canada and I can't find it anywhere.
Any suggestions on equivalent kits or piping that I can purchase?
What do i need to meet WETT certification?
I'd like to attempt this myself, if possible.
My installer quoted me over $4000.00 CDN for parts and labor and I'm on a tight budget.

Thanks

Thanks

AllfuelHST - You could check out this product. I see it on Amazon. I can't find it, but there was a post here and a rep made a few comments about the product. Maybe someone else remembers. If you need WETT certification (which I did too for my pellet stove) make sure to find your WETT guy ahead of time and consult him/her. You will need to install per the stove and pipe manuals.
 
One thing to consider is an outdoor air supply for the stove (herein and elsewhere called an OAK, or outside (outdoor) air kit. I believe this is required in mobile homes in Canada and a best practice. Hopefully, others will chime in if I'm mistaken.
 
yes with wood stove in mobile home got to have oak, don't where the quote came from but it's way out of line . must be really high on labor as parts and pieces for flue and oak shouldn't cost more than about $1000 with 1/2 of that for 4 sections of double walled flue pipe.
 
Go to any of your local hardware stores like home depo they can all order kits, better to get something local so if you need something else it is supported locally. I was able to get everything i needed at the local Rona. Any store that sells units should also be able to help you out. Make sure to talk to the inspector before you start and ask them what specifics you have to follow, i made several calls to my inspector and he was more than happy to help, when he came to do the inspection he was in and out in 5 min as he could see i followed all his recommendation's.
 
I was able to purchase everything I need from Homehardware. Selkirk products they carry(made in Canada). Go to Selkirk’s website and spend sometime looking/researching, all the stove pipe/chimney installations instructions are there including mobile home installation. Between your stove’s installation instructions and Selkirk’s installation instructions all the information will be there.

The WETT inspector will check that the installation meets EVERY clearance listed in the stove and chimney so don’t close up the inside opening until the inspection is complete and keep all the instructions for the inspector reference. My inspection took about 60 minutes and was 11 pages long.
 
Thanks for your replies, everyone. I did some research on why my quote was so high.
The WETT installer was quoting all Excel products, which isn't a bad thing for quality, but bad for my wallet lol.
I'm going to go with Selkirk products from Home Hardware.
I think my only concern right now is what type of roof flashing to install. I see some bad reviews on the rubber boots on here and other forums, but I'm concerned about leaks if I go with a metal flashing on a metal roof. Ive seen the the videos where they cut a slit, slide the flashing in and Bob's your uncle.
We get lots of snow here and it builds up on the roof, being a 3/12 pitch. Ice ans snow can back up and I'm concerned it will get under the roof flashing and cut roof panels. I don't trust caulking to save the day year after year either.
Does anyone know how hot a stainless double wall pipe gets on the outside in -20 C and will it melt the snow around the metal flashing?
 
Does your roof shed the snow normally in the winter? The wind and gravity keep my 6/12 pretty clean. Would your chimney be in a spot that you’d be able to use a roof rake to remove excess snow from an area?

I’ve wondered if some of the newer waxes made for cars would be helpful in situations like yours. Some of them can be sprayed on, last for months, and are slicker than snot. If the water drains away fast it can’t freeze. It could also help pull down snow with lack of friction.
 
I like the wax idea, just don’t wax where you’re going to access the chimney for sweeping.

As far as heat melting snow, don’t count on it. I’ve felt the chimney many times on a previous install where the chimney was a thru the wall install, 8’ away from the stove it was barely warm…by the time the flue gases got to the roof exit there shouldn’t be enough heat to melt ice.

I watched some videos where they used metal flashing, slick! There’s an outfit in the states that markets metal roof flashing made for metal roofs, above $500 plus shipping. There’s name escapes me.

Rubber boots can leak, however if you’re prepared to check where the bottom of the boot meets the metal and run a bead of sealant whenever needed due to deterioration. In my case I can usually get away with every two years of resealing. I’ve used silicone, works great but a bugger to remove. Caulk works and isn’t too bad to remove. This year(new install) I’m trying roofing tar. I’m talking about a bead as big as the boot thickness only…not applied with a putty knife. The boots aren’t the best solution but if you’re vigilant you’ll keep the water at bay.
 
The upper slit can be caulked with silicone.

Here are a couple of shots of metal roof flashing using the Excel flashing (recommended, even if the chimney is Selkirk).
