through much reading here on the journal, i am in the process of purchasing a hanging unit heater i.e. sterling, hot dawg, to replace my existing lp vented wall furnace. this wall furnace is currently installed in the middle of my 24' side wall of my 24'x32' building. this makes the termination far enough away (4') being right in the middle of two windows on this wall. from what i've seen, the optimum mounting placement would be in one of the back corners, facing the doors at a 45 degree angle. therein lies the problem, this building is of saltbox roof design, with the rear pitch steep enough that it interferes with the rear upper corners of the only 9' ceiling height. while the front wall height is 9', the rear is just over 6'. should i just mount into front corner instead? or put the heater in the same area as the current one? which i really dont want to do as it takes up wall space. any ideas on which way to go would be greatly appreciated!

motart,
The correct placement for optimal heating would be facing the garage door/window etc.. openings but you should also take into account how/where the gas piping will run (most likeley from your existing heater) and how/where you vent. Many do the horizontal venting but this requires more specific lengths and dimensions if you follow codes, which you should.
I would decide on the heater you want although most of them (Modine, Sterling, Mr.Heater) are all the same basic design but download the installation instructions and determine all your variables. It usually is not as easy as it seems as far as choice of location to meet all the parameters.
Following all the proper codes/permits should be a concern in your location decisions.

My Sterling heater is wall/ceiling mounted at 45% at the front corner ie garage door/ far wall. For me it worked out best with looks for where the vent came out, location of propane tank and being out of the way. The garage temp is even enough throughout to not cause me any concern.
dave and bd, thanks for the replies! i also had a thought of mounting and venting heater over forward most side window so that the heat will blow across the the area right inside of the doors. i might be just overthinking all of this as the area is only 768 sq ft ? and placement might not be such a problem with this small of an area?
also double checked last nite that my old wall furnace was 55k btu. and that furnace pushed the heat out onto the floor. now i dont know if a hanging 45k will do it or should i go with a 60k?

You are most likely overthinking, as you say, the best place to angle. Something is always not ideal. My heater aims at the car that is up on the lift and it also angles to door into the house. This is also where the thermostat is mounted, no big deal, I wired up a remote sensor which takes an average temp. It also means it is warmer when I walk in the garage, not such a bad thing. I know everyone recommends placing the heat on the outside wall etc, but aiming the heat to blow out when my large garage doors are open just seemed wrong to me. The temp eventually all evens out. Install the heater where it is the easiest, most convenient and complies to code.
I will leave it to more learned viewers on sizing. It depends on where in the country you are, ceiling height, insulation R value, # doors windows, expected temp range you want etc.
