Troubleshooting

Symptom	Possible Cause	Corrective Action
Poor draft	Chimney blockage	Clean chimney; check for obstructions
Insufficient heat	Wet wood/damper setting	Use seasoned wood; adjust air controls
Blower not working	Power/thermostat	Check power supply; verify thermostat setting
Smoke spillage	Negative pressure	Open window for make-up air; check draft
Rapid wood consumption	Excess air	Reduce primary air damper opening
Creosote buildup	Cool flue gases	Increase burn temperature; use drier wood

Reset: Press safety reset button if furnace shuts down due to high temperature.
