Security Measures
• Installation must be carried out in accordance with current laws.
• Current safety and accident prevention regulations must be respected at all times.
• Burner assembly, start up, operation and maintenance (inspection, servicing, repair) must be carried out by qualified, properly trained
personnel.
• Only the manufacturer is authorised to undertake repair work on the electrotechnical parts, flame detection devices and other safety
equipment.
• Changes and modifications not specified in this document and which may cause serious malfunction to the burner are prohibited..
•All work, except for adjusting the burner, shall only be carried out after the burner has stopped and after the power supply has
been disconnected.
• We shall not accept any responsibility for any damage and disturbance arising from not following these instructions !
The flame tube temperature is high. The baffle temperature is high. Handle with care.
Important information
Handing over the system to the user
• When the system is being handed over to the user, the installation engineer shall draw particular attention to the actions that the user is
authorised to carry out (when the burner is on safety for commissioning the system) and to the actions and modifications that may only be
undertaken by qualified personnel.
• The user must ensure that only a qualified professional has maintained the burner.
• This document is an integral part of the burner. Please keep it carefully in the furnace room near to the appliance.
Installation maintenance
To get the most out of your burner and to avoid operating difficulties, make a a qualified technician carries out the following:
• Cleaning the combustion head.
• Replacing the fuel oil nozzle.
• Replacing the electrodes (If necessary).
• Checking the burner's operation.
• Checking and cleaning the boiler.
• Checking and cleaning the chimney.
• Checking and cleaning the new air heater input.
For wearing parts, see the list of spare parts at the end of these instructions.

Burner description
1 Brief description
M 300 S range burners are compact fuel burners which meet standards on burners with air flow adjustment :
• They are delivered with cables connected.
• They are assembled onto the furnace with a sliding clamp.
• All of the parts are assembled on an easily accessible plate.
• The plate containing the parts is located for optimal maintenance.
• The flame is checked using a photo-resistant cell.
• Ignition is by electronic transformer.
• Insulation class : IP 21
Envisaged use
M 300 S range burners are designed to specifically operate with "hot water furnaces" for heating premises and domestic hot water.
Please contact us for other applications, industrial processes and specific applications.
Check for optimal compatibility with the burner equipment / furnace / flue in order to guarantee a low pollution operation. The layout and size
of the flue shall be in accordance with the existing directives and regulations.

Installation
Recommendations on electricity connection
A manually controlled sectioning device must be used to insulate the installation during maintenance, cleaning and repair work.
At the same time all non earthed conductors must be cut. This switch is not supplied. The burner is manufactured to operate in
a 230V - 50Hz single phase system.
This burner does not require a thermal relay to be attached. A 10 AT fuse is required for separate power supply.
Provide a separate power supply for the M 302-5 S - M 302-6 S burner.
Prior to any action on the burner, it has to be disconnected from the electricity supply. Installation and electrical connections
are to be made in accordance with existing regulations. Check that the earth is properly connected.
The connection cables supplied are certified under DIN 4791.
Recommendations for fuel connection
The burner is supplied with dual tube fuel connection: an aspiration pipe and another for the return to the tank.
It is possible to connect a single tube from the filter : It is not advisable to use a single tube connection between the filter and the burner's pump.
A filter must be attached (mesh size between 80 µm and 150 µm) in the fuel aspiration to avoid dirt deposits in the nozzle.
1 Assembly of the sliding flange
Assemble the gasket and the sliding clamp onto the furnace keeping to the direction marked 1.

!Push the burner into the fire box so that the flame moves past the interior insulation of the fire box door by 160 mm (For M 302-6 S only).
"Press the burner into the hearth door so that the turbulator exceeds the 10-15 mm insulation inside the hearth door (M 301 S - M 302-
1 S - M 302-2 S - M 302-3 S - M 302-4 S - M 302-5 S).
#Fill in the resulting gap between the intermediate tube and the fire box door with insulating, fireproof material.

%Tighten the sliding clamp screws.
3 Maintenance
Disconnect the electrical connection connectors.
Unscrew the 5 rapid action screws.
Extract the parts plate from the housing.
Position the component holder plate on the studs on the casing.
Avoid any mechanical force on the turbine. Do not use the turbine as a support point in order to stop it from turning.

Adjustment
Recommendations for measuring combustion
Fine tune the burner so that it meets the existing local regulations.
It is important that the flow of combustion products between the chimney and the furnace nozzle is sealed in order to avoid measurement errors.
In order to measure combustion, Keep to the burner's operating times:
- 10 min operation (Boiler at temperature),
- 20 min operation (Cold boiler).
After assembling and setting the burner:
- Check the soot index,
- Check the smoke gas emission values.
Keep to the advised settings to avoid having flame surveillance problems at low powers.
