Hey folks - I have a VaporFire 100 furnace on order and arriving shortly so I've been reading up on the install and configuration of the furnace before it arrives. I've been reading that draft is important so on the recommendation of some other posts here I ordered a Dwyer Mark II model 25 to measure the draft. Im a little unsure of the install though. I've seen some folks post on here that they connect it directly after the furnace and just use some copper brake line for a few feet and then attach it to the line from the Dwyer. I assume it's important to have tight connections in place for the meter to work correctly. How do folks connect the copper line to the flu pipe and then to the rubber hose on the meter itself?

I used 1/4” copper ice maker line. Used a 1/4” compression adapter to connect to the meter. To connect to the stove pipe i used a 1/2”x1/4” adapter, sent it through the stove pipe and threaded a brass shank nut on the back side to hold it in place. Kinda of confusing without pics. can up load some if you need me to.
I used a step up drill bit to drill the hole in the stove pipe, I drilled it perfectly so that the 1/2”x1/4” adapter threaded right into the pipe. I then took a 1/2” shank nut reached inside the stove pipe and threaded that on the back side to keep it locked in place. Works like a charm.

I just drilled a 1/4" hole in the stovepipe and put a length of 1/4" copper tubing in the hole...it stays there by friction and its own weight. I've also bent the tubing into an S shape and just hung it into the hole before too.
To attach the rubber tubing to the copper I just expanded the other end of the copper by stretching it out with a Phillips screwdriver and shoving the rubber into it...has worked fine for years now.
You only need to have the metal line a foot or so long to keep the rubber from getting too hot... my current setup is a lil shorter than that and is fine.
