2018-11/7-11/30 Wood Stove Install on Granite Hearth

It was time to install the Wood Stove. But, no stove is complete without a hearth!

The first burn in the stove

The stove needs to be “primed” by having a fire in it prior to installing all of the stove pipe. I think this is to burn off any creosote-causing finishes that might be present inside the stove. I set it out on the lawn and lit up some scrap wood. While that was going on, I set to work on the hearth.

I went to Second Use building materials and picked up a scrap of granite slab left over from somebody’s countertop project. I cut a rectangle about the footprint of the stove, using my angle-grinder with a diamond saw blade. Julene gently hosed it down so it wouldn’t get too chalky and dusty, while I cut. Here she is cleaning up the fresh-cut rectangle. You can see the rest of the slab resting against the saw horses in the background.

Finished shaping the hearth.

I used the angle grinder to shave off the corners into a more unique shape.

Rather than having the granite slab hearth sit on top of the raw slab counter-top, I decided to inlay it. This was a SCARY cut. I traced the shape of the hearth into the countertop, then used my router to remove the material. I used a chisel to get the corners right. It wasn’t perfect, but it didn’t have to be. I used a tile grout adhesive around the outside edge of the slab to seal it up and make a neat transition from wood to stone. It came out great!

After some coaxing, I laid the hearth down into the pocket I made for it. Then I built a heat shield behind it, with a piece of scrap metal I had been hanging on to.

I used some ceramic spacers to attach the heat shield to the wall behind the stove.

With the stage in place, I bolted the stove to the hearth and prepared to cut a hole in the roof the next day.

Scary Hole.

It’s always scary to cut a hole in the roof, but this was a relatively simple one, since there had to be a little bit of clearance for the insulated stove pipe. I estimated where it would need to come through the ceiling, using straight edges and 90 degree rulers. Then I drilled a hole from the underside, used the hole-saw from the roof side, then a jig-saw to make it even wider. With all of the trim pieces that came with the kit, there was room to fudge it a little, but I managed to get it pretty spot-on over the stove. At this point, I had to cement the pipe to the stove, because this is where it was going to live for the rest of eternity.

Capping it off.

With the stove cemented in place, I set the anchors into the roof, which you can see all gooped-up at the bottom of the frame of the photo above. Then, I put a silicone seal over that, and also bolted that to the ceiling with goop. Finally, I added the weather skirt, which sits over the silicone seal and diverts ash and water away from the base.

I don’t have a picture of it from this time, but on top of that, I put a sewer pipe cap with a flexible seal. It attaches and detaches with a single screw. I keep it on when driving. When I get to camp, I pop it off, and put another 2-foot length of double-wall stove pipe, and the chimney cap on.

Here’s a photo of the chimney cap, from the distant future!
First burn in the bus!

I added the ceiling trim piece/heat shield to the ceiling around the chimney, and it was ready to have a fire. I burned a piece of bark from the countertop project as a final bit of closure. The stove changed the entire character of the bus.

Wood Heat!

Suddenly it wasn’t just a shed anymore. Now it was cozy and habitable!
