| and flue pipes. |
2. Insufficient heat from first loadings, | Wrong setting of draft regulator |

| Restriction in chimney flue (excessive |

3. Poor heating in the rooms while | Inadequate duct installation. |
hot air plenum and furnace are hot. | Insufficient static pressure. |
| Unbalanced system (too many hot air |
| outlets for too few cold air intakes). |
SOLUTIONS
Clear air intake of any ash accumulation.
Clean heat exchanger and flue pipes.
Set draft regulator (reduce opening). Reduce distance between furnace and chimney and eliminate 90o elbows.
Maximum length: 10 feet.
Reposition ducts.
4. Furnace burns too much wood.
The thermostats controlling the air combustion damper is located too close to cold air and demands heat continuously.
Wrong setting of air intake register. Poor building insulation.
Ash drawer left open.
Furnace too small for heating needs. Unbalanced ventilation system, insufficient heat near thermostat.
Relocate thermostat.
Adjust chain between damper motor and combustion air damper. Balance the ventilation system as to increase the flow air in room where thermostat is located.
5. Fan starts too late.
Fan starting temperature is too high. Cold air return is too cold. Inappropriate location of fan limit control in hot air plenum.
Lower starting temperature (the fan limit control is normally set at 150 oF); under certain conditions, this limit should be reduced.
Reduce the cold air intake. Relocate fan limit control within the hot air plenum.
6. Creosote accumulation, very | Damp wood. | Use dry wood. |
