UNPACKING and ASSEMBLY
To safeguard against damage in transit, MDFL burners are supplied in partly assembled form.
Spill-back Burners
MDFL burners systems comprise of the following units:
- The burner body, complete with hinged extension, flame tube assembly and control panel if fitted
- The gas control train
- The oil pump unit
- A free-standing or wall-mounted control panel, if supplied
To assemble the burner:
- Fit the gas control train to the burner body using the gasket supplied, ensuring that the gasket is
fitted correctly with all holes corresponding with those on the burner flange.
- Connect the combustion air impulse pipe from the SKP75 air/gas ratio controller to the left side of
the hinged extension.
- Connect the multi-pin plug on the gas valve train to the socket on the rear of the burner-mounted
terminal panel.
- Place and secure the oil pump/pumping and heating unit in the desired position. The floor
mounting arrangements are shown on page 17 (distillate fuels). Connect the unit to the burner
pipework using the flexible connectors provided.
- Fix the control panel in an appropriate position and make the electrical connections to the burner
package and oil pump unit, as shown in the wiring diagram contained in the instruction pack
attached to the burner.
Note: In some circumstances it may be advisable to fit the burner casing to the appliance before
attaching the gas control train. It is recommended that lifting gear should be employed if necessary.
INSTALLATION
General
Ensure that the appliance is suitable for the heat input of the burner. If there is any doubt in this area
reference should be made to the appliance manufacturer. Detailed burner performance data are
presented in the Appendix of this handbook.
Fitting to the Appliance
If the burner is to be fitted to a new appliance, refer to the appliance manufacturer’s
recommendations.
If the burner is to be fitted to an existing appliance, a mounting flange must be provided as detailed in
the section of Burner and Components Identification. Ensure that the joint between the burner and
the mounting flange is sealed effectively using the gasket provided.
The flame tube should be flush with the inner face of the appliance combustion chamber. Up to
10mm protrusion may be acceptable (refer to the appliance manufacturer) however it is not generally
permissible for the flame tube to sit within the appliance firing tunnel.
Special extensions may be specified by the appliance manufacturer, for example in the case of a
reverse flame boiler.
Electrical Power Connection
Connect a three-phase, 50 Hz electrical supply to the burner, observing all applicable Codes and
Standards. The electrical connections required are shown in the wiring diagram contained in the
instruction pack attached to the burner. These diagrams also show the external auxiliary control
connections which must be made.
If the burner is supplied as part of a packaged appliance/burner unit, refer to the appliance
manufacturer’s instructions.
