CHAPTER 21

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 fire to not burn as hot or efficiently. 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.
