CHAPTER 20
AIR LEAKS
Checking For Air Leaks
Once your HEATMOR™ system is up and running, we recommend that you conduct an initial check for air
leaks from the furnace. To detect an air leak, put some green grass (or something which will create heavy
smoke) into the furnace. When the furnace is smoking, cover the chimney and turn off the blower and watch for
smoke leaks.
Air leaks cause the re to not burn as hot or efciently. In result you will use more wood to achieve the desired
water temperature. The HEATMOR™ Outdoor Furnace is designed with over / under forced drafts and if air
leaks occur, it would change the output of the furnace.
AIR LEAKS INTO THE FIREBOX WILL CAUSE THE FORMATION OF EXCESS CREOSOTE.
