Now that winter is almost over, I am going to install a furnace in my garage/shop. Great timing, I know.
The furnace is a LP directvent, counterflow wall furnace. When I plumbed my house, I put a tee in near the garage for just such an occasion. The tee is in the crawlspace of the mudroom and will require me to go up into the dividing wall at least 4″ before it can turn to protrude into the garage.
Since the mudroom is on a side wall to the right of the car bays and I would like the furnace to sit on the back wall between the car bays, I thought I would run from the protrusion at the floor vertical to the garage attic, diagonal to the middle of the gable and then down to the furnace. All plumbing would be black pipe.
Is this alright code-wise. I figured on leaving the verticals outside of the wall as I always thought there was a code concerning that. If there isn’t such a code, I might conceal them in the wall.
Additionally, I was wondering about the legalities of plumbing in a line to support an outdoor grill. Not really planning that yet, just an idea.
Any thoughts or concerns?
thanks

Sounds like the only way to do it. Don't forget the length of pipe to get there might stretch your gas capacity.
In other words, your pipe sizing may be too small now with that addition. Moreso if you think of adding a BBQ which can be huge load.
It may affect the sizing in the rest of the house.
Your routing seems okay, now get someone to do a pipe sizing on your whole house.
