METHANE LIGHTING AND REGULATION

• The air contained in the piping must be bled out, with due
precautions and with doors and windows open. Open the fitting
on the piping situated near the burner and then open a little the
gas shut-off valve (or valves). When the characteristic odour of
gas can be smelled, close the cut-off cock. Wait long enough
for the gas in the room to disperse, and then connect the burner
to the gas pipe again and open the valve again.
• Check that there is water in the boiler and that the gates on the
system are open.
• Make sure that the products of combustion can be released
freely (boiler gate valve and stack open).
• Make sure that the voltage of the power line to which the burner
is to be connected corresponds to that required by the burner
and that the electrical connections (motor or main line) are
designed for the voltage rating available. Also check that all
the electrical connections carried out on site are in accordance
with our wiring diagram.
• Make sure that the combustion head enters the furnace to the
extent specified by the boiler manufacturer. Check that the air
adjustment device on the combustion head is in correct position
for the fuel supply required (the air passage between the disk
and the head must be reduced for low supply and relatively wide
when supply is higher). Refer to the chapter "Air regulation on
the combustion head".
• Fit a pressure gauge of appropriate scale to the pressure intake
on the gas pressure switch (if the amount of pressure to be used
allows it, we recommend to use a water column instrument; do
not use instruments with indicator hands for low pressures).
• With the switch (1) on the mimic panel switched to "O" and the
main switch turned on, manually close the remote control switch
and check that the motor revolves in the correct direction. If
necessary, exchange the position of the two cables in the line
that feeds the motor in order to reverse the direction of revolution.
• Now switch on the main switch. This powers on the control
device, and the programmer turns on the burner as described
in the chapter "Operation description". For burner adjustment,
refer to the supplied instructions for the "BT 3xx" electronic cam.
• After having adjusted the "minimum", (200) bring the burner
towards the maximum, using the controls on the "BT 3xx"
keyboard.
• We recommend that you check combustion using the appropriate
instrument at all intermediate points on the modulation route (from
200 to 999), checking the gas flow rate by reading the meter.
It is essential to check, with a suitable instrument, that the
percentage of carbon monoxide (CO) present in the fumes
does not exceed the limit set by regulations in force at the time
of installation.
• Now check the proper automatic operation of modulation.
This ensures that the equipment receives the signal from the
electronic modulation regulator, if the burner is the modulating
model, or from the second stage thermostat or pressure switch,
if it is a two stage progressive burner.
• The air pressure switch stops the equipment operation if air
pressure is not at the expected value. The pressure switch
must be set to close the contact which should be closed during
the operation, when the air pressure in the burner reaches
the sufficient value. The pressure switch connection circuit is
self controlling. Therefore, the contact which is meant to be
closed in a non operating status (fan stopped and thus no air
pressure in burner), should in fact be in this status, otherwise
the command/control equipment will not be switched on (burner
remains inoperative). Please note that if the contact meant
to be closed during operation does not close (insufficient air
pressure), the equipment carries out its cycle but the ignition
transformer is not switched on and the fuel valves do not open.
As a result, the burner stops. To ensure the air pressure switch
correct operation, with burner at the minimum output, increase
the adjustment value until reaching the triggering value which
must be followed by the immediate burner shut-down. To unblock
the burner, press the special pushbutton and return the pressure
switch regulator to a sufficient value in order to measure the air
pressure existing during the pre-ventilation phase.
