Just finished installing the 75000 BTU Big Maxx. The coils inside the unit are glowing red - is that normal for this heater?
Mr. Heater Big Maxx - Is this right?

Well my 45k doesn't do that. Is the fan running in the back?

Might be set up for the wrong gas.... Propane or Natural??? Improper gas pressure????

It is an LP. It only glowed the first time (maybe something in the line?). Tested the pressure, it was a little low, so will be getting a new regulator Monday to see if that helps.
Thanks for the replies!

When it is real cold out, you will get a lower pressure reading than when it is warm. If it was a one time event, then it might just have been the protective oil burning off the tubes. I wouldn't be concerned. Does the fan cycle on and off properly?

It was very cold out, but the garage & tank was about 60 degrees, as we have a 75000 BTU Corn stove right now but insurance co. won't let us keep it in the garage soi the Big Maxx is replacing it (Grrrr!). But yes, the fan cycles on and off properly, and we thought it may be oil on the tubes, but wanted to ask around just in case!
How hard should the fan blow? I mean, it's very warm, but doesn't seem like it's pushing much air. Maybe it's because we're used to the loud fans of the corn stove compared to the whisper of the Big Maxx!
I recently installed a 45K BTU Nat. Gas Mr. Heater Big Maxx and had the same issue. The center heat exchanger tube at the first 180 degree bend following the burner glowed bright red during the initial firing. Subsequently there is is still a red glow at that point but much less intense. The unit has been in use for 5 days now. The aluminized coating on the steel tubing has broken down at that hotspot and flaked off and blistered on the tube. I have left a couple of messages with their tech. services number but have not received a response. They have an online contact form at their website but I was unable to get it to work.

Return The Unit! And pick up a Modine "Hot Dawg" Their service is excellent and there is a 10 year warranty on the heat exchanger!
I know ...what a Pain in the ***. But over the last few years I have heard of more problems with those damn things.

Why wont insurance let you have a corn burner? How did they find out about it? I would just leave the corn burner in.

Anyone called or gotten ahold of Mr. Heater yet on this? I am curious.

I find the lack of response to be strange. Whenever I called about a problem that I was having with a new unit, they were quick to send a replacement part. Unfortunately, the replacement wasn't the problem, so they continued to send me parts to change until it was resolved. It took 3 tries, but it worked, and now I have spare parts for the future. My problem was a cracked electronic board that had a hairline crack that was not noticed originally. I found that they were very attentive to customer service, and they did follow up to make sure that everything was working to my satisfaction.
