Important notes
Ecoflam burners have been designed and
built in compliance with all current
regulations and directives.
All burners comply to the safety
and energy saving operation
regulations within the standard
of their respective performance
range.
The burner must not operate out-
side the working range.
The quality is guaranteed by a quality and
management system certified in
accordance with ISO 9001:2008.
The MAXFLAM burners are designed for
the combustion of heavy oil.
The burners comply with
standard EN267. Assembly and
commissioning must be carried
out only by authorised
specialists and all applicable
guidelines and directives must
be observed.
Burner description
The MAXFLAM burner is a 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.

Function - General safety functions
Operating function
- Switch-on the burner. When reaching
the preset temperature on the working
thermostat, and with boiler’s thermostat
closed, the control box starts the fan,
the fuel pump and the ignition
transformer. At the same time, the
resistors are activated, to keep fuel
temperature into the heater at a
constant value.
- The motor starts, the igniter is switched
on and the preventilation period of 25
seconds commences.
- During the preventilation period, the
furnace is monitored for flame signals.
- At the end of the preventilation period,
the fuel-oil solenoid valve opens and the
burner starts.
- The igniter remains switched off while
the burner is in operation.
Controlled shutdown
- Boiler thermostat interrupts heat
request.
- The fuel-oil solenoid valve closes and
the flame is extinguished.
- Burner motor switches off.
- Burner enters standby.
Safety function
A safety shutdown occurs:
- if a flame signal is present during
preventilation (parasitic flame
monitoring).
- if no flame is produced within 5 seconds
(safety time) of start-up (fuel
authorisation).
- if no flame is produced after an
unsuccessful restart attempt in the
event of flame failure during operation.
A safety shutdown is indicated by the
malfunction lamp lighting up and it is then
only possible to reenable the burner by
pressing the reset button after the cause
of the malfunction has been rectified.
For further information, see the
automatic combustion control unit

Start up - Adjusting burner output - Oil pressure regulation
Burner start
Before starting the burner, draw oil in until
the filter is completely filled. Then start the
burner by switching on the boiler regulator.
Open the bleed screw on the oil filter to
allow the oil line to bleed fully during the
preventilation phase. The negative
pressure must not fall below 0.4 bar. Close
the bleed screw when the filter is
completely filled with oil and oil is flowing
out without bubbles.
Burner output adjustment
Use the pressure regulator to adjust the oil
pressure in accordance with the burner
output desired. Monitor the combustion
values continuously as you do so (CO,
CO2, soot test). Adjust the airflow
gradually if necessary.
Optimising combustion values
If the combustion values are not
satisfactory modify the position of the
combustion head. By doing this the burner
ignition conditions and the combustion
values change. Compensate for the
change in airflow if necessary by adjusting
the air flap position.
Note: observe the minimum required
flue gas temperature specified by the
boiler manufacturer and the
requirements demanded of flue gas
ducts for avoiding condensation.
Oil pressure regulation
The oil pressure, and therefore burner
output, is adjusted using oil pressure
regulator 5 in the pump.
Turn to
- right: to increase pressure
- left: to reduce pressure
Connect a pressure gauge at point 3 (with
R1/8" thread).
Checking negative pressure
The vacuum meter for checking negative
pressure must be connected to point 4,
R1/8". Maximum permissible negative
pressure is 0.4 bar. At higher negative
pressures, the fuel oil gasifies, which
causes scraping noises in the pump and
ultimately leads to pump damage.
Adjustment of fuel thermostats
The working resistor thermostat must be
set to 100°-140°C, while the safety ther-
mostat is preset. Said adjustments can be
slightly modified following the type of fuel
and particular uses.
A - Working thermostat (100°-140° C).
B - Stand-By thermostat (150° C).
C - Firing head thermostat (120°-140° C).
Operating check
Flame monitoring must be checked for
safety as part of initial commissioning and
also after servicing or if the system has
been out of operation for any significant
period of time.
- Starting attempt with flame monitor unlit:
the automatic combustion control unit
must switch to malfunction at the end of
the safety time
- Start with flame monitor lit: the
automatic combustion control unit
!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.

be carried out by qualified personell.
The system operator is advised to take
out a service contract to guarantee
regular servicing.
Attention
• Disconnect the electrical supply before
carrying out any maintenance or
cleaning work.
• The blast tube and firing head may be
hot.
Checking the exhaust gas temperature
• Check the flue gas temperature at
regular intervals.
• Clean the boiler if the flue gas
temperature is more than 30°C above
the value measured at the time of
commissioning.
• To simplify the check, use a flue gas
temperature indicator.
Burner maintenance positions
• After removing the screws pull the burner
out of the flange and turn to maintenance
(as show in picture) to :
nozzle change
electrodes change and setting
combustion disc cleaning/change
air cylinder setting
Maintenance on the burner
• Clean fan and housing and check for
damage.
• Check and clean the combustion head.
• Replace oil nozzle.
• Check ignition electrodes, readjust or
replace as necessary.
• Fit combustion head. Observe
adjustment dimensions.
• Fit burner.
• Start burner, check flue gas data, correct
burner settings if necessary.
• Check oil supply components (tubes,
pumps, oil feed tube) and their
connections for leaks or signs of wear,
replace if necessary.
• Check electrical connections and
connection cables for damage, replace if
necessary.
• Check pump filter and clean if
necessary.
Nozzle and cleaning replacement
Use only the suitable box wrench provided

Cleaning of filter on the preheater
Removing of the filter:
1 Switch-off the burner and make cold to
leave.
2 Take off oil thermometer bulb C.
3 Loosen screw B and drain part of the fuel
from the heater, until the fuel level drop
below the filter.
4 Unscrew and pull out the stem filter A from
its seat.
5 Clean the filter and reassemble the parts
as shown by the picture, then fit it in its own
seat.
It is advisable to replace all filter and valve
gaskets whenever they are removed.
Note: that when the burner is working
the heater has a pressure of abt. 23 bar,
and that it becomes very dangerous to
carry out said operations with the burner
running.
Note: Always check the position of
electrodes after having replaced the
nozzle (see illustration). A wrong position
could cause ignition troubles.

Fault diagnosis and repair
In the event of a malfunction, first check
that the prerequisites for correct operation
are fulfilled:
1. is the system connected to the power
supply?
2. is there oil in the tank?
3. are all shut-off valves open?
4. are all control and safety devices,
such as the boiler thermostat, low-water
detector, limit switch, etc.
adjusted correctly?
If the malfunction persists, use the
following table.
It is not permitted to repair any
components relevant to safety. These
components must be replaced by parts
with the same order number.
Only use original spare parts.
NB: after each operation:
• under normal operating conditions
(doors closed, hood fitted, etc.), check
combustion and check the individual
lines for leaks.
• Record the results in the relevant
documents.
