It looks like a 15 amp breaker would be fine, here is the spec sheet

As you can see the unit only pulls 3 amps.

Hope this helps

Mr. heater big maxx keeps blowing fuses, Replaced everything in it and still does it. sometimes it will run for a while


Maybe its the wire or the outlet. Does the wire get hot? Try a different outlet that is on a larger amp breaker.

No spark. My HSU75NG MR. Heater (Big Maxx) will not start on its own. It purges fine ,calls for heat fine, gas flows fine; BUT there is no spark from the Electrode Igniter. Which I have replaced. The


The capacitor in that unit is for starting the motor that drives the blower fan. It has no impact on the ignition of the gas burner. On the control board, there is a light that should be flashing, can you tell us how many times it is flashing?

I have a Big Maxx heater and it won't stop blowing and won't heat. The fan just keeps running! Anyone know what could be wrong?


Your pressure switch may not be activating (ie closing and making contacts) This means you could have a blocked flue, clogged pressure switch tube or a bad pressure switch. The pressure switch is a safety feature to ensure your exhaust is not blocked and operating correctly. Find owners manual. Look at trouble shooting section. Open cabinet and look for error code light. If blinking 3 times, try "jumping" the pressure switch. To jump pressure switch you need to clear code be turning off power. When the unit/thermostat calls for heat the power vent fan starts first, this is when you need to jump the pressure switch. You need to do this in sequence. That is the unit first starts the power vent exhaust thus activating the pressure switch allowing the ignition cycle to the burners and heat. So the power vent fan needs to start first BEFORE you put the jumper on to bypass the pressure switch. Once the jumper is on it will call for ignition after approx 30 seconds. If ignites your problem is one of the 3 stated at the opening of this paragraph

I have a mr. heater big maxx. It is a 75000 btu natural gas. The preasure switch failed closed/open. How do I reset it? Or do I have to replace it?


the vent pressure switch will have a rubber type hose off it to the combustion fan housing. pull the hose off and poke the conector with a paper cilp or wire to make sure it is not plugged at the housing. make sure the vent fan is running and jumper the switch if it comes on replace the switch if not look else where for your problem.a volt meter is a great tool . voltage across a switch means it is open and no voltage means its colsed. i should say to also check your venting as it maybe blocked. there is no reset
