Mr. Heater Unit Heater Installation & Operation 

Thanks

Can you explain why a stainless steel ductwork is required over other galvanized? Thanks

I'm thinking about installing this unit in my garage/woodshop. Would small amounts of sawdust be an issue with the open flames? If so, is it possible to configure the heater to draw combustion air from outside the building?

Can we use 3/4" CSST for the unit Heaters? And unit heater input 25000BTU & output is 207500BTU. Please advice.

I just bought one of these and went to install it today. Realized it didn’t have a power cord at all. What type of power cord do I need for the big maxx 80k btu heater

Building a 32x30 pole building with 14' ceilings. Going to buy the 80,000BTU unit. to heat the building with propane. What wire is needed for the thermostat? I'm going to run the wire for it prior to the walls being closed up. Thanks

Can you confirm that the unit can also be mounted vertically with the vent and gas input on the floor side? Not horizontal as all of your pictures show.

Should the horizontal venting slope upward or downward toward termination? There seems to be a lot of conflicting info regarding this. My Mr Heater instructions say to slope upward 1/4"/ft towards termination, but the recommended vent kit says to slope it downward.

Installing the 50,000 btu in my pole barn. I am installing the underground yellow gas line from house to barn the distance is 100ft. Is 3/4 inch yellow pipe sufficient for this?

Which category 3 vent part is used to interface with the heater vent output? Local menards stores don't have any sort of saf-t vent adapters and none of the 4 inch pipes (angled, straight, etc) fit over the output either?

What gauge wire should the 3 wire 110v AC supply wire be? Also, what gauge should the thermostat wire be?

I have a Selkirk Corp section of 4" duct with drain and with 3 tabs. I don't know what the tabs are for, but the only way it fits the Mr. Heater is to bend them back and push it in. But, then the Amerivent elbow is the wrong sex to fit the Selkirk drain section. Are they not compatible with each other? Should I just crimp one to make it fit?

Great video! If this is a little beyond the DIY abilities of a homeowner, do you have any recommendations on who to try to have install it? It appears that with all gas, electric, and venting, is there then a carpenter, plumber, and electrician involved?

Is there any need for outside air for combustion? The duct is for exhaust right?

I have just installed the 50,000 heater in my garage and I see the green LED blinking once per second but it never changes when I set the thermostat up to activate the heater. What should I check?

So since this unit is vented, do I have to concern myself still with CO2 build up within my garage?

My Mr. Heater 50,000BTU with 4" double wall insulated vent leaks through the vent pipe during heavy rain. No external leaks, just a small internal leak that comes through the exhaust vent at the T, rear of the unit. Any thoughts?

Why is there a 8 foot minimum clearance between the floor and the bottom of the heater?

How loud is this heater? Can I use this in my office?

I cannot find a piece to connect the back of the unit to the 4-in double insulated pipe

You don't show up how to hook up the exhaust pipe

Manual about horizontal ducting is a bit confusing. in the paragraph explaining horizontal ducting it states that the minimum length is 5' while the diagram says 3' minimum. A bit confused which is it. Thx

Can two thermostats be connected at the same time? Is there a way to install both the (simple/dumb) Mr Heater thermostat and a "Smart" or programmable thermostat simultaneously? So the "dumb" one would maintain a minimum 35 degree temp all the time, yet the "smart" one would warm the room to the desired temperature when programmed to or when activated.

my garage ceiling is 9ft 6in so the bottom of heater woul be at 7ft 6inch not the recommende 8 ft why wuold that make a differance then it says you can mount lower than 8 ft in parking garage?

I read in the installation manual it must be at least 6 feet from a corner where two exterior walls meet. Why?

I have an 8 foot ceiling in my garage. Will this work?

What is the jet number on the jets for natural gas

Natural gas conversion to lp propane. What do I have to change?

Where can I get a venting kit

Forgot the 3 inch dirt pocket “drip leg” per code.

Instructions on this MHU50NG Natural Gas Unit to start up are TERRIBLE!!! No where does it tell you how to access the gas valve!!! It tells you to turn the valve on and shows a picture of it but not where it is. Obviously it is not on the outside of the unit but which side, front or back are you to remove?!? In this video it does not mention that you do anything with the gas valve?!? In the manual it does not mention anything about the circuit board and the green LED?!? Hopefully this is a good unit but right out of the box it would appear maybe not. Maybe I am blind in one eye and cannot see out the other but I cannot make sense of it. I will have to call them to answer a few questions, where the gas valve is should not be one of them.

Anyone thinking of buying this brand of heater DON'T! Nothing but junk . Only owned my for 5 years before the motherboard went , replaced it and only lasted 1 winter ! Do not buy unless you like throwing money away
