Setting up Shop in Dayton (aka Cholla's Retreat)

[ORIGLS6]

Great work (and look) so far Sam. I'm guessing (since you spend some time at TGJ) you're familiar with Thomas Payne's shop. If you ever get to our neck of the woods let me know and we'll take a side trip to his place. You'll be smiling the entire time.

Love what you're doing, and FWIW, that heater will keep you and the puppies more than toasty. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Hey Dennis. thanks, if that is the shop that was an old repair shop from the 30s or so and this fellow completely restored it.....I love it! His talents are impressive! I would love to see it. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

That's the one. Thomas and his wife are extremely nice people. I've been there a few times; once with my daughter. Even she enjoyed the 'tour'. He's a true car guy and even races a '66 Chevy II L-79 car in Pure Stock. The restored auto shop is amazing and I always come home with new ideas for my own place.

(See you at MCACN this year?)

Slow going on the plumbing for the propane heater. 1st shot is what the connections will look like above the concentric vent adapter box which passes through the attic and up to the the intake and exahaust caps that will be placed above the roof line. The top cap is the exhaust vent for the hot gases. The cap below it is the fresh air intake for an external source of combustion air. The system is called 'concentric' because the fresh air intake pipe is located external to the double wall (type B) hot exhaust air vent which runs up the center of the fresh air pipe. One advantage of this set up is that it requres only one hole through the roof. Next shot is the adapter box attached to the ceiling.

More boring stuff. One reason I am posting this here is I have found very little detail on DIY install of a concentric vent system. The instructions from the manufacturer are very vague and not much help. I called the manufacturer and they would not address any of my questions because I was not an HVAC guy. I realize the seriousness and pitfalls associated with a self install and I will be getting my system inspected by the county and the propane provider to ensure a safe system. I have recently installed and successfully passed inspection for a new natural gas line in my home for a gas range.

Next few shots are of the pipes going in between the heater and the concentric adapter box.......

Think this will keep the weather out? [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]

Nice work Sam [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

[mockingbird812]

Just slather some roofing tar in there. It'll be fine... lol. Nice job on the professional looking install!

[mockingbird812]

Thanks. Rain is moving in so had an early morning session to at least make the system water tight.

This in one of the critical pieces to ensuring Wx tight seal. This is a weather collar that you can manipulate to create a good seal by drawing it up tight around the outer duct pipe and securing it with fasteners ...


After placing this flashing over the hole in the roof, I traced the oval shape of the base of inner flashing with a crayon...


Hook blade is best, but I muddled thru with a standard box-cutter type to remove the shingles...


Dry fit...


Roofing/flashing glue (if you look carefully, there is a subliminal message in the pattern)
