Starting Up And Regulation - baltur TBG 45 ME Instruction Manual For Installation, Use And Maintenance

ENGLISH

STARTING UP AND REGULATION

• Bleed out the air contained in the gas piping, with due precautions
and with doors and windows open.
• Open the union on the pipe near the burner and then open slightly
the gas shut-off cocks.
• Wait the time necessary for the gas in the room to disperse outsi-
de. Re-connect the burner to the gas pipeline.
• Make sure that the mains voltage corresponds to the manufactu-
rer's requirements and that all electrical connections made at the
installation site are effected properly as illustrated in our wiring
diagram.
• Make sure that the combustion products may be freely vented
through the boiler and flue dampers.
• Check that there is water in the boiler and that the gate valves of
the system are open.
• Make sure that the combustion head is long enough to enter the
furnace following the measure specified by the boiler manufactu-
rer.
• Install a pressure gauge with adequate scale on the pressure
outlet of the gas pressure switch.
• 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 devi-
ce, and the programmer turns on the burner as described in the
chapter "Operation description". For burner adjustment, refer to
the instructions for the electronic cam supplied.
• After having adjusted the "minimum", (200) turn the burner gra-
dually to maximum, by using the controls on the electronic cam
keyboard.
• Check combustion (CO, O2, NOx) using the appropriate instru-
ment at all intermediate points on the modulation route (from 200
to 999), checking the gas flow rate by reading the meter.
• 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 therefore be adjusted so that it is triggered
to close the NO (normally open) contact when the air pressure in the
burner reaches the set value.
The connection circuit of the pressure switch is self-controlling so that
the NC contact (normally closed) which is meant to be closed at rest
(with the fan stopped and consequent lack of air pressure in the bur-
ner), is actually in this condition. If it is not, the control box is not swi-
tched on and the burner does not start.
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.
The gas pressure control switches (minimum and maximum) prevent
the burner from operating when gas pressure does not lie between the
expected range.
The minimum value pressure switch makes use of the NO (normally
open) contact which is closed when the pressure switch detects a pres-
sure higher than its own setting.
Adjustment of minimum and/or maximum pressure values on the pres-
sure switches must be performed when testing the burner, on the basis
of the pressure measured in each case.
The triggering (opening of the circuit) of any of the pressure switches
when the burner is running (flame on) locks out the burner immediately.
The pressure switches are connected so that the triggering (opening of
the circuit) of any of the pressure switches when the burner is running
(flame on), locks out the burner immediately.
Check the efficiency of the thermostats or boiler pressure switches
(they should shut down the burner when triggered).
