Kuma Stoves AR-10 - Manual (Page 10)

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.
