Burner description
MAX GAS PAB are two-stage, fully
automatic, monoblock type burners.
Burner head is designed to get the lowest
emissions in terms of NOx and unburnt
particles in order to maximize the heat
generator efficiency. Emissions can be
different respect to the ones recorded in
the lab because they depends a lot on the
generator on which the burner is fit.
The installer must comply with compulsory
rules. Avoid for instance dangerous
atmosphere or not ventilated rooms.
Packaging and handling
Move the burner still in its packaging using
a trolley or forklift, taking care not to drop it
and elevating it no more than 20cm from
ground level. After having removed the
packaging, check that the contents are in
good condition and correspond with what
was ordered. If in doubt, contact the
manufacturer.
The burner must be installed by a
qualified individual.
If the weight and dimensions do not allow
for manual lifting, ask another operator for
help or use a forklift, harness the burner
using belts if no eyebolts are available.
Use the accessories provided
(flange, gasket, pins and nuts) to
install the burner onto the boiler,
taking care not to damage the
isolating gasket.
We can accept no warranty liability
whatsoever for loss, damage or injury
caused by any of the following:
- Inappropriate use.
- Incorrect assembly or repair by the
customer or any third party, including the
fitting of non-original parts.
Provision of the system and the
operating instructions
The firing system manufacturer must
supply the operator of the system with
operating and maintenance instructions on
or before final delivery. These instructions
should be displayed in a prominent
location at the point of installation of the
heat generator, and should include the
address and telephone number of the
nearest customer service centre.
Notes for the operator
The system should be inspected by a
specialist at least once a year. It is
advisable to take out a maintenance
contract to guarantee regular servicing.

Function - General safety functions
Description of functions
When the system is switched on for the
first time, after a power failure or safety
shutdown, after a lack of gas or after the
system has been out of operation for 24
hours, the pre-ventilation period of 24
seconds begins.
During pre-purge period:
- blower pressure is monitored
- the combustion chamber is monitored for
flame signals.
At the end of the pre-purge period:
- ignition is switched on.
- main and safety valve are opened.
- burner starts.
Monitoring
The flame is monitored by an ionisation
probe. The probe is insulated and
fitted to the gas head and is routed
through the flame disc into the flame
zone. The probe must not have any
electrical contact with earthed parts.
The burner switches to lock-out if a short
circuit occurs between the probe and
the burner earth.
During burner operation, an ionised
zone is produced in the gas flame
through which a rectified current flows
from the probe to the burner head. The
ionisation current must be at least 7 μA.
Safety functions
- If no flame is produced when the burner
is started (gas release), the burner will be
switched off at the end of the safety
period, lasting no more than 3 seconds,
and the gas valve will close.
- If the flame goes out during operation,
the gas supply is interrupted within one
second. A restart takes place. Once the
burner starts, operation is continued.
Otherwise, a safety lock-out occours.
- If there is a lack of air during reventilation
or operation, a safety lock-out occours.
- If there is a lack of gas, the burner does
not begin operation or switches off.
A waiting time of 2 minutes follows. This is
followed by a further start attempt. If there
is still no gas pressure, a further waiting
time of 2 minutes follows. The waiting time
can only be reset by interrupting the
power supply to the burner.
Waiting times: 3 x 2 min, then 1 hour.
In the event of controller shutdown
- Controller thermostat interrupts heat
request.
- Gas solenoid valves close.
- Flame goes out.
- Burner motor switches off.
- Burner is ready for operation.

The TCG 2xx control and safety unit
controls and monitors the forced draught
burner. The microprocessor-controlled
program sequence ensures maximum
stability of time periods, regardless of
fluctuations in the power supply voltage or
the ambient temperature. The automatic
combustion control unit is designed to
cope with brownouts. Whenever the
supply voltage drops below its rated
minimum level (< 170V), the control unit
shuts down - even in the absence of a
malfunction signal. The control unit
switches itself back on again once the
voltage has returned to normal levels (>
178V).
Locking and unlocking
The control unit can be locked (switched to
malfunction mode) by pressing the
unlocking button and unlocked (fault
deleted), provided the unit is connected to
the mains power supply.

Start up - Adjusting burner output
Gas pressure diagrams in appendix
Minimum gas pressure required are
indicated in the diagrams in the appendix.
These values have been determined in
our test labs and are useful for the first
switch-on as final setting must be done
using a combustion analyzer.
How to read and adjust the values:
- determine the output required
- determine the combustion chamber back-
pressure
- read the minimum gas pressure required
in the diagrams in appendix.
Optimising combustion values
The factory setting shall be modified
according to the output requeired.
The diagrams of air/head setting
that are available in the appendix
of this manual are a guide for ensuring
that the burner functions as well as
possible.
!Risk of air blast!
Continuously check CO, CO2and soot emissions when adjusting the output of the burner. Optimise combustion values in the
event of CO formation. CO must not exceed 50 ppm.
N.B. observe the minimum required
flue gas temperature specified by the
boiler manufacturer and the requirements
demanded of ue gas ducts for avoiding
condensation.
