Heater Mounting Location...Help!

[JonnyC]

I'm starting the task of hanging and running gas line to a 50k Big Maxx heater tomorrow, and at the last minute I'm doubting my mounting location.

Here's my garage. Basically a standard 2 car with the right stall being extra deep. I was originally going to mount it right in the corner above the rear door, but that doesn't provide much room at all in the attic to access the vent pipe, and the vent on the roof will be close to the gutter. So I was going to move it further out into the garage and have it point at the corner, like this...

But when figuring out the best way to mount it with 24" on-center trusses, I realized it would be cleaner and easier to just mount it so it's parallel with the wall and pointing at the center of the garage door. The back right corner would probably be the best, but the gas pipe will be exiting the basement right where the air compressor is, so I would have to run it around.

Do you guys think there would be much difference in how the air circulates? Any advice would be appreciated

Here's another image for reference...

I would go in the other corner...The Right side.
You may wind up with a cold area in front of that door.

Or Add a ceiling fan in the middle of the garage.

Mine is dead center in the back of my Garage and I use a Ceiling fan along with it (fans blowing UP) and it really makes a difference in warming all corners.

Yeah, that is the ideal location. I guess I'll run pipe up and over the back door, along with conduit. I might use unistrut as I'll be running a few more branches of conduit as well.

****, now being over in that corner I could run the vent out the side as there is no soffit, but I haven't researched that yet, only going through the roof.

So I was reading more about venting it out the side of my garage, but read in the manual that new code requires category III stainless pipe be used, whereas going verticle I think you only need double wall B. The category III piping is really expensive! No wonder I saw full kits that were $250+.

So I think I'll stick with my original location...I think

My Gut says that with a 50k BTU heater, you'll be fine with almost any location. Either a ceiling fan or even a big oscillating fan would help to move the heat around if you need it.

I'm putting mine in the corner, slightly angled to the far corner. Being cheap, I was going to go through roof, but in the long term, out the side wall, is cleaner, with less chance of roof leaks, etc.
Also planning on using a ceiling fan to help move air; from comment above, says to blow UP. What's the theory in Up vs. down?

 

[JonnyC]

I'm really doing too much research here. Right now the placement simply depends on if I want to vent through the roof or through the siding. I have vinyl siding so I've been reading all about how to do the j-channel around the thimble, as I've never worked with siding before and want to make sure an excess amount of water doesn't get behind the siding. And if I go the vertical route, I want to make sure to get the roof flashing right.

i just did a horizontal vent with a 50k big maxx. i used a vinyl mounting block and have my thimble through that. i really should post some pics!
