5. -Carburetor out of adjustment (decrease high-fire screw).

-Cold flue.

-Flame set too high (flame impinging on baffle too much).

-Faulty gasket (door rope, glass seal, or relief plate seal).

-Excessive residue in burner bottom.

6. -High wind, or unstable draft condition.

-Incorrect carburetor setting (increase low-fire screw).

-Faulty carburetor. (rare condition)

7. -Abnormally high, gusty winds (If you live in a windy area, a draft stabilizer

may need to be installed in the pipe to compensate).

-A wind-directional cap or vacuum cap may be helpful to prevent wind gusts and

down drafts from affecting pressure.

8. -No oil in tank.

-Valve in fuel supply line shut inadvertently.

-Fuel supply blocked (plugged filter, frozen water).

-Carburetor on/off lever tripped.

9. -Stove door having been open for a while and then shut (a roaring noise can occur for

a short period until draft stabilizes).

-Draft pressure too high - adjust carburetor to decrease high flame size, or add a tee

in connector pipe with a draft stabilizer

10. -Carbon deposits (operate de-coking rod).

-Draft pressure too high.

11. -Carburetor adjusted too high, allowing too much flame impingement on stove top.

-Flue plugged or dirty.

-Dirty burner or plugged fuel inlet (operate de-coker/clean burner bottom)

-House pressure problem (inadequate supply of air to stove, or fans operating in the

house increasing negative house pressure).

-Faulty or deteriorated catalyst.

-Blocked or inhibited air supply to stove (check outside air supply to stove or room).

-Faulty gasket (door rope, glass seal, relief plate seal, or burner gasket).

12. -Oil leaking from any connection.

-Poorly adjusted burner

-low flue pressure due to chimney size or geographic conditions affecting draft.

Consider smaller flue size to increase negative draft pressure.
