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.
