Big Maxx heater on a shelf

[sjoseph316]

My gym is coming along good thanks to all the help and information on this site. I'm in Ohio and have been heating it with a 100k BTU torpedo heater and surprisingly it works well. Ready to get the 125k big maxx going, have to run the vent through the side wall on the left, it will end up being about 4 1/2 feet so that is more than the minimum stated in the manual. Black pipe is going down and out the same wall. I'm researching all that now and figuring it out.
I'm going to bolt the heater down on the shelf, I'm wondering if I should lift it off the shelf more? I put the brackets on the bottom so the heater is about an inch off the shelf. The manual says 0 inches on the bottom clearance but I want to be sure. I could mount 2x4's or 4x4's along bottom to raise it up and then bolt it down, I'm wondering if you all think that is necessary?
The clearances from the back and sides are beyond what is required per the manual. Thanks!

I would give a bit of cleance. Use the angles it comes with and screw them the the bottom of the heater and use them for "legs".

If 0 clearance and in the manual wouldn't think about it.

I like this suggestion. Also get it to the edge as close as you can.

Thanks everyone, I used the angles it came with and then screwed in a 4x4 to those angles and it’s about 4 1/2 inches off the shelf and just a few inches from the edge. It’s also bolted to the shelf so it won’t move. Haven’t run it yet as the propane isn’t connected, hopefully soon.
I can‘t find anything that says it’s ok or not ok to sit the heater on a shelf. The manual says 0 inch clearance from the bottom, but it also says at least 8 ft from the ground. It’s 10’9” off the ground. So you guys think it’s good? Thank you!

The only issue with the shelf would be clearances to combustibles. The manual says zero, and more clearance doesn't hurt anything. As long as you have decent room for air movement you should be fine. As for height form the floor, it is simply keeping it high enough so it isn't a head knocker and low enough so the fan can blow air to the floor. You can mount it twenty feet up , but the floor may be cold.

Over the years I have installed many shop heaters and ever situation is different. Some got mounted six feet from the floor as the shop had a crazy low ceiling, some get mounted twenty feet up because the customer had trucks an farm machinery and much lower the heater would be in the way.

Holy ****, 125k btu? How big is that space?

I thought the torpedo heaters introduced a lot of moisture into the room, and exhaust fumes. No?

I think you need to go back and read the OP's post.

It’s 30x60x16 on the sides, about 17 to the bottom of the truss and 20 to the peak. I have double bubble in the entire structure with a 2 inch gap between the bubble and the metal. Two nice ceiling fans that move air well. It was just built the end of October so it’s an ongoing process. I spray foamed all the corners and along the eaves to seal it up. Some insulation is coming, along with slowly putting osb on the walls. I Bought a new master 140k btu torpedo heater and it works nicely while we are out there. We open thewindow right behind it like the manual says to do and I only smell fumes slightly when it shuts down and I’m right by it. The only section that sweats is the metal right below the heater, I haven’t put the double bubble up yet because I’m not done there. I’ve checked behind the double bubble in several other places then put staples back in and no moisture at all.
I‘m in Ohio and my thermometer said 6 degrees the other evening when myself and the kids we out there lifting and shooting basketball and it stayed 55-62 the whole time with the heater only kicking on a few times once it got to temp. The ceiling fans make an incredible difference.
here are a few pics of progress. I’ve done everything myself with the sole help of this forum and I’m incredibly greatful.

Ok, yeah that's a big space and the lack of insulation has a big impact. Once you add that, run time on the heater should drop a lot.

Looks nice lots of room for activities

Man, this is looking really nice! You are doing a great job!

Thanks friends!! Some things have been frustrating, learning how to do that I’ve never done before but the kids have been out there every day playing hoop, passing football, volleyball and running around and that makes it all worth it

I've got pretty much the same exact setup, same colors and everything! Mine's a 30x60x14'. I'm working on electrical now. I have zero insulation in mine but hopefully that will change in the next year or so.

That’s awesome! I love it, big enough for the kids and me to do everything in. I almost went 14’, going 16’ cost me about 4k extra with materials and the big telehandler I had to rent but I had to make sure it was high enough for basketball and volleyball.
I would highly suggest sealing up the corners and eaves with foam and around the windows and doors with silicone, it helped mine tremendously, and ceiling fans are a must with the high ceilings. I got two of these and they move some air. https://www.homedepot.com/pep/Hampt...VCWNHAR0ldQ5YEAQYASABEgLIKvD_BwE&gclsrc=aw.ds
