ment servo motor with a rotation increase or decrease.
If the pressure or temperature limit is reached even at
the minimum delivery for which the full stop device is
adjusted (thermostat or pressure switch), the burner will
be stopped by the action of the stop device. By lowering
the temperature or pressure below the level at which
the stop device intervenes, the burner is switched back
on at the previously described programme. If the flame
fails to appear within 3 seconds of opening the pilot
gas valves, the control equipment "blocks" (completely
stops the burner with the warning light coming on). To
"unblock" or release the equipment, press the button.
Flame modulation is obtained by installing the following
components, which are supplied on request:
- Modulation kit for boiler temperature or pressure
- Automatic integral proportional modulation adjuster
"RWF 40".

COMBUSTION CHECK

For a correct air/gas ratio you have to get a carbon
dioxide reading (CO ) for the methane of at least 8% at

the minimum burner supply and up to the optimal level
of 10% at maximum supply.
It is not advisable to exceed a 10% value or it could run
with too little excess air. This could in turn cause (with
atmospheric pressure changes, the presence of dust
in the air ducts) significant quantities of CO (carbon
monoxide) to be present in the system. To prevent
dangerous situations from arising, it is essential to
always check, with a suitable instrument, that the
percentage of carbon monoxide (CO) present in the
fumes is not greater than the maximum permitted
level of 0.1%.
IGNITION AND GAS REGULATION
(METHANE)
1) If not already done when connecting the burner to the
gas pipes, taking the necessary measures and open-
ing doors and windows, it is necessary to bleed the air
contained in the pipes. Open the union on the pipes
close to the burner, and slightly open the gas stop
cock(s). Wait until you smell the typical gas smell, and
then close the cock. Wait for the necessary time, ac-
cording to the specific conditions, until the gas present
in the room is dispersed outside and then restore the
connection of the burner to the gas piping.
) Check that there is water in the boiler and that
the plant dampers are open.
) Make sure that the combustion product dis-
charge can occur freely (boiler and chimney
dampers open).
4) Check that the electrical line voltage corresponds
to that required for the burner, and that the electri-
cal connections (motor and main line) are preset
for the available voltage value. Check that all

modulation switches to MIN (minimum) and MAN
(manual). The control box thus receives voltage,
and the programmer determines the enable of the
burner as described in chapter "description of the
operation".
Note: Pre-ventilation is carried out with open air
and thus, during the same, the regulation
servomotor is enabled, and it runs a complete
opening stroke up to the "maximum" set. Only
when the regulation servomotor returns to the
"ignition" position, the control box continues
its ignition program by enabling the trans-
former and the ignition gas valves.
During the pre-ventilation step, make sure that the
air pressure control switch changes position (from
off position without pressure detection it must switch
to the off position with air pressure detection). If
the air pressure switch does not detect the suf-
ficient pressure (it does not switch position), the
ignition transformer and the flame gas valves are
not enabled, and thus the control box "locks". Note
that some "locks" at the first stage are normal since
in the valve ramp pipes there is still air that must
be discharged before having a stable flame. To
"unlock", press the "unlock" push button. At the first
stage there may occur further "locks" due to:
