Question 1

what is the thermostat temperature range in degrees high/low?

Accepted Answer

There is no real thermostat in Mr. Heater. It is more of a reostat the controls the time the 5 panels are on and off. At the number 1 setting the panels are on a short time and off a longer time. As you go from 1 up the panels stay on longer and the off time gets shorter. I have not been able to run on the 5 setting as the CO2 sensor turns the heater off after two cycles of setting 2. My external carbon dioxide sensor also goes off after 15 minutes of operation and on setting 2 and after the Mr Heater CO2 sensor turns off the propane. I would not recommend this heater to anyone.

Question 2

After starting the unit up for the very first time and letting it heat up for 5 or so minutes my fire/smoke detectors went off, is this normal?

Accepted Answer

I had a scenario where this heater made a serious billowing smoke show. Kicked the smoke detectors off immediately. Only happened 2- 3 times in a 2 ish year period. It happened with this propane heater too. Don't let this scare you though. Can happen with any infrared heater. It only happened several times over a period of about 2 years. So it probably only happened 1 out of a thousand times where the pilot light was on, but for some reason when it went to light up the burner bricks it malfunctioned and billowed out smoke like you wouldn't believe. Made it hard to get to the heater to turn it off. ALWAYS worked after simply turning it off, and ligting it up again. Maybe another reason why you must have working smoke detectors. Doesn't keep me from buying another one! Overcome your fears. Doesn't mean you won't first feel afraid if smoke suddenly starts pouring out of the kitchen.  Lol. NEVER let your fears control you. Everything breaks it's just a matter of time. Keep safety # 1.

Question 3

I am concerned about having to use a battery to ignite the pilot light. Is this a problem and are there other types of ignition systems?

Accepted Answer

From your question I'm not sure why you are concerned about using a battery. It is of course as safe as any other method. If you are concerned that the battery will go dead, it's not a problem; you simply unscrew the battery compartment cap, lift out the AA battery and drop another in to replace it. Easy Peasey. In my case, after 3 years my heaters "sparker" that lights the pilot refuses to work. Even so, I still have the capability to use a grill lighter to fire it up.

Question 4

It's a vent free product but do you need to crack a window for fresh air to circulation?

Accepted Answer

If it is being used in a small confined area I would say you should open a window a crack (due to the propane odor)
