Maintenance & Service - Landa ECOS 7000 Operator's Manual

Burner Air Adjustment:
The oil burner on this machine is preset for operation
at altitudes below 1000 feet. If operated at higher
altitudes, it may be necessary to adjust the air band
setting. Adjust air band for a #1 or #2 smoke spot
on the Bacharach scale. If a smoky or eye-burning
exhaust is being emitted from the stack, two things
should be checked. First, check the fuel to be certain
that kerosene or No.1 home heating fuel is being used.
Next, check the air adjustment on the burner. An oily,
smoky fire indicates a lack of air and the air band
should be moved to allow the air to flow through the
burner. Sharp eye-burning fumes indicate too much
air flowing through the combustion chamber. The air
band should be readjusted to allow less air to flow
through the burner.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discon-
tinue use and readjust air bands.
NOTE: If a flue is installed, have a professional ser-
viceman adjust your burner for a #1 or #2 smoke spot
on the Bacharach scale.
For additional burner component information, see
Burner Assembly Exploded View page . It is
recommended that the oil burner be serviced yearly or
as needed. Contact your local service center.

To adjust, start the machine and turn burner ON.
Loosen two locking screws found in the air shutter
openings (see illustration) and close air shutter until
black smoke appears from burner exhaust vent. Note
air band position. Next, slowly open the air shutter
until white smoke just starts to appear. Turn air shutter
halfway back to the black smoke position previously
noted. Tighten locking screws.
If the desired position cannot be obtained using only
the air shutter, lock the air shutter in as close a position
as can be obtained, then repeat the above procedure
on the air band setting.
