TARTING STEP RLA P4

This trimmer is a slow ignition

regulator and it is calibrated at
minimum during factory test.
Use a small screwdriver for any

adjustments. Turn clockwise to
increase gas pressure to the
burner at start-up (by setting

the trimmer to maximum
calibration pressure of

modulator – see page 16).
Turn counter-clockwise to
decrease gas pressure to the

burner at start-up (by setting
the trimmer to the minimum

pressure at start-up will
correspond to minimum
calibration pressure of

modulator –see page 16).
Through the RLA commutator
you can verify the minimum

gas pressure adjusted to the
modulator. Remove the

commutator from the MET-GPL
selector located on the
RAMIRE 2 circuit board and

insert it on the RLA CM1
selector located on the same
circuit board. Once pressure on

the gauge has been checked,
remove the commutator and

insert it on the MET-GPL
selector.

HEATING TIMER

Delays start-up times of the various ignitions once
the boiler has reached optimum temperature (the

range of adjustment is from 0 to 6 minutes, the
value set during testing at the factory, to 2.5 min.)

Use a screwdriver to adjust the delay time. Turn

clockwise to increase time and counter-clockwise
to decrease time down to zero.

MAXIMUM HEATING TRIMMER.

The trimmer is calibrated at 80% of the

max. rated output during factory testing.
For the first ignition of the boiler, adjust
according to heating power of the

system. Use a screwdriver to adjust it.
Turn clockwise to increase, counter-
clockwise to decrease.
