Burner Air Adjustment - Landa PGDC5-3500 Operator's Manual

Burner Air Adjustment

The oil burner on this machine is preset for operation at
altitudes below 500 feet. If operated at higher altitudes,
it may be necessary to adjust the air band for a #1 or #2
smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location's environment as-
needed for best smoke spot and performance
compliant with local, state, and federal regulations.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation,
discontinue use and readjust air bands.
ATTENTION: Si de la fumée blanche s'échappe de
l'évacuation du brûleur pendant le démarrage ou le
fonctionnement, cesser d'utiliser et réajuster les
bandes d'air.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.

Coil Removal
Removal of coil, because of freeze breakage or to
clean soot from it, can be done quickly and easily.
1. Disconnect hose from pump to inlet side of
the coil.
2. Carefully disconnect thermostat sensor from
electrical connection.
3. Remove all the fittings from the inlet and discharge
side of coil.
4. Remove the burner assembly from the combustion
chamber.
5. Remove the 3-3/8" bolts from each side of coil and
tank assembly (these bolts are used to fasten tank
to chassis).
6. Remove the two bolts which are underneath the
bottom wrap (to keep the coil from moving.)
7. Remove tank top wrap exposing insulation
and coil.
8. Bend back insulation tabs.
9. Carefully fold back the insulation and remove insu-
lation retainer plates and coil.
10. Replace or repair coil and any insulation found to
be torn or broken.
11. Reinstall 1/2" pipe nipples into coil.
Coil Reinstallation
Reinstall new or cleaned coil by reversing Steps 9
through 1.
Final Note
The 12 VDC burner systems can draw as much as 18
amps! For such motors to run properly, the battery and
engine charging system must be kept in good condi-
tion, and the engine must run fast enough to
adequately charge the battery. Do not throttle down the
engine at any time while the machine is operating.
