My heater emits a strange odor when | first open the box and when I turn the heater on for the first time. Why is this happening?
This is normal. This heater is treated with a special heat safe/resistant coating. This odor will sometimes be present when the box is opened. When the coating is exposed to heat, it produces this particular odor during the first few hours of operation. This will dissipate after the break-in period. If you are sensitive to odors, you may want to pre-burn the unit in a garage with the door open until the initial odor dissipates.
If my heater runs on its max wattage setting, how many BTUs is that?
This heater is intended to be used as supplemental heat in areas most needed. It may take several minutes to several hours to heat your area, depending on various factors. The below chart provides BTU translations for different wattages.
| WATTAGE | BTUS |
| 1,500 | 5,118 |
| 1,000 | 3,412 |
| 750 | 2,559 |
| 500 | 1,706 |
