4.0 out of 5 stars Heater nice. Installation was work!, January 8, 2009
This review is from: Mr. Heater Big Maxx 75,000 BTU Natural Gas Garage Unit Heater #MHU75NG (Kitchen)
Ordered the propane model to put up in a Morton Building workshop. Package arrived quickly with minimal damage to outside cardboard box. Nice unit and fairly easy to lift (I am 6' 190 lbs. average jock) but recommend two people to lift in place on ladder or other device.

Things to consider for installation: Installed two joist between trusses in the attic to hang the unit from (time consuming). Venting horizontal is easier but I perfer vertical. Think this process out. This unit requires a 4" exhaust vent. I went through a metal roof and used a Dektite on 4" double wall exhaust pipe. Make sure you have the appropriate tools, fasteners and sealers before starting this part of the project. Hooking the exhaust vent to the unit should be well planned too. It is not easy and you should have the exhaust vent pieces you plan to use to take some rough measurements prior to fit up. I hung the unit using threaded rod on C channel so I could adjust the unit up or down, side to side,... Read more

I purchased this heater to heat my 1100 square foot garage/shop in California. Although the weather here is generally mild, it does get down to about 20 degF in the winter months. The heater easily heats the shop up quickly and keeps it warm. I mounted the heater to my 10 foot ceiling by installing two lengths of predrilled angle iron to the ceiling and hanging four 5/16" all thread rods with a hook on one end. I attached the all thread at the four corners of the heater and then lifted the heater and hung it from the angle iron by passing the hooked ends of the all thread through holes in the angle iron.

My only complaint about this product is poor workmanship in assembly. When I opened the box, I found several of the screws which were supposed to hold the fan protection cover in place laying in the bottom of the box. I was able to find all of the missing screws and nuts and install them correctly. There was also damage to some of the sheet metal on the unit... Read more

I recently purchased this heater after reading the one review.I live in canada and had it shipped to a border store where I picked it up . The box was damaged from some kind of strapping , although the heater LOOKED ok.Once I got home and opened the box I was very UN- IMPRESSED ! The right side of the front panel was pushed in at both upper and lower corners,not too bad , I could straighten it out , not that I should have to.Upon further inspection I could not find how to hook up the vent. WHY ? BEcause of the 3 small screws that hold the vent blower motor to the heat exchanger 2 were gone ( to be found in the tubes when I tipped it over)and one was barely holding on. It was flopping all over during shipping consequently destroying the heat proof gasket between the two parts.some DISSASSEMBLY required!I repaired the unit by purchasing a fire retardent material and making a new gasket and using a better quality stainless steel sheet metal screws.next I had to tighten 80 % of the sheet...
