What's the yellow triangle with the #2 in it? It looks as if the matters labelled l1 and l2 are the wires within the line in. L1 is black (warm) i bet, and l2 would be white. So i can twine the line-in white to the white conductor at the fan. Then the road-in black (hot) is going to the fan aspect of the fan/limit manage. Wired to which conductor? White or black? If the thermostat is a simple switch then i bet it doesn't depend. Then the opposite conductor (black or white) can get stressed out to the black line at the fan. How need to this be stressed? I don't know what is meant by way of "fan" and "restriction". I am assuming that "fan" refers back to the blower on the range. However what is the restriction? I bet i just do not recognize what the thermostat is doing with 2 strains entering/out of it.
Also attached to the stove, there is a line in, a 3-conductor grounded line with a 3-prong plug on the end - for 120v power supply. There's additionally a blower at the range, which takes 120v strength, and has 2 conductors - white and black. It forces the warmed air thru the output duct. All the wires are meet in a junction box, and none are connected. I've a timber-burning range, that is used as an auxiliary heat source within the residence. There may be a regular electric furnace, and adjacent to it is the range. The warm air duct (out) from the stove connects at once to the enter air duct on the electric furnace.
