                                                      Sterling GG heaters can be converted to separated combustion when this kit is added to the heater. Separated combustion heaters draw combustion air from outside to ensure that the unit will always have plenty of fresh clean air. The fresh air supply reduces common concerns about dusty, dirty, or high humidity applications. You can also decrease heating costs by as much as 10% because no cold outside air is being sucked into the structure when the heater is running. Pipe must be purchased...
