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 :sad: ), 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! :thumbup:

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.

:lol: 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).

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.

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 ??? :wtf: 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.

[spit on it]

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 nipple 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!
