Pics: Mr Heater Big Maxx install

[Scott]

The heater is installed somewhat temporarly until the drywall goes up. Here are a couple of pictures of the install of a Mr Heater Big Maxx 45k natural gas heater. The install was pretty straight forward, I cut 4" out of my 1" gas line then threaded the ends installed a tee, union, drip leg and valve. I used a gas hookup kit for a furnace(yellow line) so that it is easy to unhook due to the flare fittings on the hose. I wired in an extra switched oultet for 110v power. The only thing left to do is hook up the flue pipe (Lowes did not have the right stuff ), need to go to HD to see if they have the right adapter tomorrow. I bought a simple digital thermostat for temp control.

I turned on the heater for a quick test, it's nice and quite and heats up in a hurry. Now onto the rest of the garage remodel!

Uh... Looks to be upside down there sir...

Those are like Hot Dawg heaters...you can mount them either way.

Nice job Scott. It's unbelievable how quiet these units are. It must be because of the large diameter fan run at a slow speed. They included an extra sticker with mine so you could replace the original if you wanted to hang it upsidedown.

 

[Scott]

Yup, it is. It came with another sticker so I should fix that, otherwise I will hear about that till the end of time! The flue pipe and gas connection seemed to look better with it that way(it puts them towards the top of the unit).

 

[rasputin]

Do they make an electric version? I really do not want to run gas lines.... It's a PITA!!!
Thanx.

 

[Scott]

There are quite few companies that make electric versions. Look up Dayton heaters on this forum.

 

[spud]

Mine looks upside down too, because the stickes is upside down, nice install BUT... did you use regular 14/ 2 wire for your plug to your furnace ??? or was it white extention cord cable .

 

[Scott]

I initially used romex because I had it around, I have since changed it over to appliance wire.

 

[stinky]

Its just me, but I would move the flamables or put some kind of a fire wall on the shelf.

 

[Scott]

The shelf is further away than it looks, but probably a good idea.

i picked up a hr heater 75,000 natural gas and it wont light up. there is gas going to the unit, it clicks like it wants to light, but no fire. any info would be great.... where did you put the ground?

 

[Junkman]

Check to make sure there is gas getting to the unit. It is is getting gas, and there is spark, there should be some flame. If it isn't lighting then you might have another problem. Hard to diagnose with so little information. When I had a problem like that, it was that the sensors were not detecting a flame and it would go off on the safety. Once I got all the logs lit, there was no more problem. I had a problem that the flame didn't jump from one log to the next, so the top 3 or 4 were not igniting.

I don't think it is to code if you use a union in a gas system. To join pipe you need to use Lt/Rt Treaded ****** and coupling.

Also be aware that once you tighten that flexable tubing, you can't reuse it, I bought a kit today with the same thing and it says you can't reuse that tube.

 

[blairtruck]

what does the flashing light in the unit say

 

[jbcat2]

It is ok to use a union in a gas system as long as it is not installed in a confined space (inside a covered wall). JB

 

[69satelite]

unions pass code here in minnesota on gas lines that might just be code in your area

 

[Steve1968LS2]

How much was that unit.. in CA here but it's cold in the winter.. 450 sq-ft garage.

Looks like a good option since I have a gas line handy.

Thanks

ive just bought one of these myself and ur pics show the same scenario i'm looking at, the 2 hangers that come with it are now wide enough to span truss to truss (which thru out the world is 24" if i'm correct) i guess that would take brains eh? so now i gotta engineer something like you did with your hanging system which involves me going into the insualtion filled attic, oh the joys of stupidity!

Ordered my Mr. Heater on Friday. Should arrive by 9/10, 45,000 BTU. I'm using it to heat a 384 sq. ft. detached workshop. Did any installation hardware come with the unit?

 

[padronanniversary]

Are you guys getting deals on these ? If so would you please share ? I am in the market for one as well. Need to heat the garage up before winter.

 

[regguy1]

I hung my Mr Heater 45K BTU like this, I made a cardboard template from the
shipping box. I put the template up to the ceiling at the angle I wanted the heater at (I have drywall) and punched holes through the drywall at the bolt locations, then went up above and screwd 2x4's betweem the trusses so I could put lag bolts into them. I pre drilled pilot holes and had a couple guys hold the heater up and I put the lags in with a ratchet. I was easy.

(Some photos before and after finishing)

CNCMAN,
They come with a metal bracket, but other than that they do not come with any bolts or threaded rod. Search my posts for my install, i documented my install pretty well and have some pics too.

I was under the impression that the PE gas line is only supposed to be used below grade you have it exposed inside the building, does that meet code in your area? The smallest fire would melt that stuff and you'd have a blow torch in your building.

I have one of those Mr. Heater 75000 BTU units. (Won it in a raffle) and the only question I have is running the flue through the exterior insulated/drywall wall. The "Thimble" that is required to go through the wall, how far does the insulation need to be from it and how do you seal the outer end from the elements. The cap to run horizontal is it different from a vertical flue cap? BTY you guy's did a nice job on the installs! Thanks in advance.

 

[Jim51]

Try these guys: http://cdepot.org/ ..... a 45,000 btu unit runs $479 I believe they ship free in the lower continental.

The "Thimble" that is required to go through the wall, how far does the insulation need to be from it and how do you seal the outer end from the elements.

I am in the same position right now. Where the thimble would pass through the exterior wall is also home to the majority of my electrical wires that go to my sub-panel. The wires are all tacked down but is there a clearance issue with electrical wires? Obviously they would not touch the thimble but is there any problem with the thimble being between the same studs that the electrical runs up?

It's covered by drywall in the wall and the ceiling tiles above.

I wouldn't use the area between studs that have electrical wires running through them, even it is legal in your jurisdiction. Too great of a chance of a wire being effected by the heat of the chimney...
