[QUOTE=David Carrol;32976]Gordon do you mind sharing some pictures?
David,
As usual, I modify everything. Full extention ball bearing slides added.
Looking closely, there is a heater register under the couch, just forward of the cabinet. My usual chair is directly across from the register & the thermostat is directly above. When the furnace would first come on, cold air would blow @ me & the furnace would short cycle because of the thermostat placement. I added the register over by the door where the heat loss is the greatest. I also changed to 4" rigid ductwork to increase flow. The register under the couch is not used.
Need to finish the front as the register is up against the wall & comes out under the co pilot chair & heats nothing !
