I am installing, and permitting, a Reznor UDX-45 unit heater in my garage. It is hung and now I am tackling the venting. I am venting horizontally and need Class III stainless vent which I have two problems with.
First, all my local HVAC supply houses only sell to contractors- not the unwashed masses such as myself- can anybody recommend a brand of class iii venting and/or a source for it? Home depot and the like around me (Central Oregon) only carry Type B.
Second, can you mix and match class iii single and double wall? If I understand this correctly, I only need double wall to pass through thimble and the exterior wall. My run will consist of the minimum possible straight out of the heater, a 90 degree elbow, a straight 4ft section, then another 90 and through the wall. I have to jog it over to achieve 3ft vertical clearance from the eve on my gable end.
This shouldn't be that hard. I'm very frustrated, any help would be appreciated.
