ran gas line to detached 2 & 1/2 car garage. Bought 75000 hot dawg gas heater along with heat only thermostat and 24 volt 2 terminal transformer, directions for each unit only does not show how all 3 are hooked up. I believe that white from transformer goes direct to the 3 white wires in heater. Black from transformer goes to thermostat and then from thermostat to 2 black wires in heater, like on off switch, but would like to verify that so I dont blow myself up, any advise greatly appreciated. Thank you.
