I am searching for a temco manual or someone that has installed this specific unit tec36-5j any support would be very much appreciated I am even willing to pay just for information. I am trying to verify that when this unit was originally installed there was a gap between the firebrick and the metal box in the one I have there is a two or 3 inch gap. So the firebrick is away from the metal box and held out by bracket. I can't find anyone with any knowledge on this specific unit. As I am in a terrible situation with my home. Thanks so much Todd
