Bigg Maxx Heater with scissor trusses

[z28dad]

Anybody got any good ideas on mounting this heater with scissor trusses? I was planning on putting the heater at an angle so that it would throw the heat to the largest part of the room. I want to use a piece of kendorf across the trusses, then thread the all thread between the kendorf and heater. It would work fine, if the truss ceiling were flat, but the scissors produce a challenge.

I'm thinking about trying to cut some 2x4's to level above the upper ceiling area of the truss. This would level the kendorf so that the all thread would be plumb to the heater.

I also thought about scrapping the kendorf idea and just mount 2x4's or 2x6's above the trusses and then drill the holes to where the all thread would be plumb.

I'm still brainstorming on this one. Any help, I would appreciate it. Thanks, Russ

Cut wedge-shaped blocks with the same angle as the rise of the lower chord of the truss, then install these such that the top surface is now parallel to the floor. Attach these with nail plates, then lay either the strut or lumber on top and screw through the shim block and into the truss lumber. Use allthread rod to hang your heater, one set being a bit longer than the other, of course.

Thanks Greatbear. I'm going to give it a shot. This is one of those installs that I have been dreading.

Simple means of marking your angles for cutting is to take a block of wood and a level up a ladder with you, set the block on top of the bottom board of the truss, hold a level against it, make it level, then mark a line across the block. Use the block as an angle cutting template for whatever you decide to put up there.

I spent the last couple of days getting the heater in the ceiling. To complicate matters I put it at an angle. The front of my garage is at an angle and I wanted the heater facing the furthest point of the garage.

Anyway, I cut the wedges and set my height first, I needed the vent to be at least 18" below the soffit. Then I used the wedges to aid in getting the heater level. I could get all 4 rods level, but I had trouble trying to get all of them plumb. I got it very close so I decided to lock the kendorf down. I cut some 2x4's and joined them to the trusses. Then I ran some lags through the kendorf into the 2x4's that I added. I also fastened the wedges to the 2x4 piece as well. The trouble come in when I trying to cinch the all threads down. This 3/8 rod is pretty flimsy to me, but its what fits the brackets. Anyway I never could get all of the (4) all threads plumb. I could get close, but that was it. I decide to at least get the heater level and then get the rods to where they looked OK by my eye at the floor. I think it will look better once the sheetrock is up also.

Is it normal for the heater to have a little movement in it? It can move back and forth as much as a 1/2 inch. Its the rods that are actually moving. I think the sheetrock will stiffin it up some. Just not sure if there is something else I should do. Also it disturbs me that the only thing holding these brackets on the heater is a few sheet metal screws.

Here are some pics, let me know what you think. Thanks Russ
