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

in connector pipe with a draft stabilizer
