Please confirm Mr. Heater Big Maxx wiring

Steve671 · Dec 7, 2009

So I just wanted to confirm that I am using the correct wiring schematic before I connect these wires. I have the Mr. Heater 45k Big Maxx gas heater and the Ritetemp thermostat. Here are photos of the board in the heater, the thermostat, and the page in the manual that I am intending of following. Does this look like the correct wiring diagram?
Thanks,
Steve

By what I see that should work for you. Wire it just like it shows and then turn the power on and see if the fan will come on when you turn the fan on to manual, it should. Then turn the t-stat on and get the temp up so that it will tell the furnace to start. It should turn the pre-fan blower on and within about a minute it should kick the ignition on. :thumbup:

Unless you plan on running the fan without the heat, you only need to connect R-W, you don't need to wire to G.

Thanks for the help guys. Got it working and now it is much more comfortable to work in the shop during the cold.
