troubleshooting
Appliance smoking.Has the chimney had time to get hot?
Is there adequate supply of combustion air?
Is the outside air damper opened?
Is the smoke passsage blocked anywhere in the appliance or
chimney?
Is the smoke fl ow impeded by too long of a horizontal pipe or too
many bends?
Is it a weak draft perhaps caused by a leaky chimney, a cold outside
chimney, too short a chimney, or a chimney too close to a tree or a
higher roof?
Bypass is closed while front door is open.
