Adjustments before first firing (light-oil operation)

• Combustion head setting
The setting of the combustion head depends exclusively on the
maximum delivery of the burner.
Turn screw 5) (Fig. 14) until the notch shown in diagram (Fig. 15)
is level with the front surface of flange 6) (Fig. 14).
Example: Burner RLS 100
maximum burner delivery = 23.1 GPH.
If diagram (Fig. 15) is consulted it is clear that for this delivery, the
combustion head must be adjusted using notch 3, as shown in
(Fig. 14).
N° Notches
Maximum fuel oil delivery USGPH
NOTE:
In case of high altitude installation site, head setting must re-
fer to the "corrected capacity" according procedure descript-
ed at page 10.

Installation
• Pump adjustment
No settings are required for the pump, which is set to 174 PSI by
the manufacturer. This pressure must be checked and adjusted (if
required) after the burner has been ignited.
The only operation required in this phase is the application of a
pressure gauge on the appropriate pump attachment.
• Air damper adjustment
The first time the burner is fired leave the factory setting unchanged
for both low and high fire operation.
• Ignition pilot adjustment
Place the pilot and electrode as shown in (Fig. 16).
The pilot works correctly at pressures ranging from 6 - 12" WC.
