S 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.
