Questions about 6V power adapter:

1) center ground ?
2) O.D. of plug ?
I have many transformers ( I never throw them away with their discarded equipment ) and maybe I can use what I have instead of buying a new one.

The ac power adapter listed below is the only adapter that is designed for The Big Buddy Heater. Use of any other adapter can void the warranty.

Thank you for your inquiry. The tip is a 2.5mm tip. They sell the same adapter at area RadioShack stores. Unfortunately, I cannot recommend repairing the plug itself.

Yes. I have mine hooked up to a 20lb tank using a Mr. heater 12' hose with regulator and quick disconnect, which I recommend. I am using mine in my deer blind. Both panels heat up my blind really fast, this is a great heater. I think I'm gonna get another one.

Staff Answer
When operating the heater at altitudes over 7,000 FT. above sea level, the unit may not burn as bright as in lower altitudes. This is normal. At higher altitudes, the heater may shut-off. If this happens, provide fresh air, wait 5 minutes and re-light.

answer 2
I live at 6500 ft elevation and it works great. The problem comes with the oxygen sensor on the heater. It may not function above 4500 ft because of the decrease in oxygen. However, the heater itself functions. I have 3 of these and use them on a daily basis!!

We use ours with the quick disconnect hose and a 20LB cylinder at 9,600 feet in a small 16x12 cabin. It never shuts itself off, burns hot and bright and brings the interior temp to 70 degrees when its 25 degrees outside within 35 minutes. Don't let the altitude make you not buy it. It works fine at altitude.

Question

can it be placed on a carpeted floor

I see a comment that says that it was too hot to place on a wood floor and consequently had to be placed on bricks. That makes me wonder if it is safe for a carpeted floor.

The manufacturer does not recommend using this heater on a carpeted surface. They recommend placing a sturdy, hard surface such as a wooden board underneath the heater if carpet were present.

No, but only one side of this heater will heat up. You need bottles on both sides to get the maximum temperature output. If you only need a little heat, one bottle on one side would be fine.
