Kuma Stoves SHASTA - Manual (Page 9)

EVERY TWO WEEKS:
*The de-coking rod must be operated at least twice a month to eliminate carbon
deposits that build up where oil enters the burner bottom:
1. Open access door on side of stove.
2. Twist and pull de-coking rod out until it stops (angle bend on the end of the
rod will be outside the stove body). It may be necessary to use a pair of pliers
to move de-coking rod in and out as the packing nut is tight around rod to
prevent leakage. Be careful as packing nut and rod may be hot. Use a glove.
3. Rotate handle 360 degrees 4 or 5 times and then push handle in until handle is
just inside the stove body.
4. Close access door.
*Note: If flame is burning lower than expected, you probably have carbon build-up in
the line or burner bottom.
