Here ya go, some answers regarding operation at altitude -
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.

I've been using this exact model for years without any problems. The elevation where I live is 7,560'.

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!!

It's regularly called on to work for us at 7,500 feet and higher. It works fine.

The big buddy requires too much oxygen at higher altitudes. We found that the smaller version works well at high altitudes and heats our fifth wheel well.
I have a short attention spa
