INTRODUCTION

Fuel This handbook has been produced to enable users to install, commission and use P Series burners safely and efficiently. At each stage the conditions that should be met and the adjustments and other actions which should be carried out are detailed and the locations of the various components and…

Modulation By Electro-Mechanical Systems

P Series burners can be supplied with a Landis and Staefa RWF40 modulating controller. This unit is designed specifically for the control of boiler temperature or steam pressure in oil- and gas-fired heating plant. The system comprises a reversible motor that is coupled directly to the cam shaft of…

Gas Supply

The pipework, supplying the gas to the burner, must be appropriate to local conditions and must be constructed and installed in compliance with appropriate Codes and Standards. It shall be of sufficient size to satisfy the pressure and volume flow requirements of the burner under all firing…

For residual oil burners the pipework should be

insulated, trace heated and thermostatically controlled. Electrical Power Supply A three phase 50 Hz electrical supply is required. Power requirements are listed on the Burner Specification Sheet on Page C.2 Technical Specification. The power supply provided must comply with all relevant Codes and…

Air Supply

A floor-mounted fan provides the air supply for the system, although the fan can be suspended for the smaller sizes of burner. The flange on the rectangular outlet is drilled for bolting onto the air damper section of the burner unit. For safety, a wire mesh guards the circular inlet of the fan. The…

Oil Nozzle

P Series pressure jet burners use a Fluidics atomizing nozzle as shown in diagram Fluidics Oil Nozzle on Page C.7. The primary function of the nozzle is to spray oil in a suitable pattern into the combustion air stream at a rate commensurate with the appliance’s thermal rating. Oil Solenoid Valve…

Data Transfer Interface (DTI)

A further option is the DTI which is a data acquisition system that can collect the operational data from up to 10 MM modules on one site. The data can be transmitted via an RS 232/422 link to a local computer or building management system using the MODBUS protocol. Alternative DTI firmware allows…

COMMISSIONING

INDIVIDUAL S ETTING R ECORD

- This manual contains commissioning sheets (Pages D.14 and D.15) of essential information that should be completed by the commissioning engineer with individual details of the burner. These details should be verified periodically and changed as adjustments occur. - - S AFETY It is essential that…

- - - - Commissioning, operating, emergency shutdown and maintenance instructions for the plant. Establish that the operation of plant other than that being commissioned will not have an adverse effect on the operation of the plant to be commissioned, and similarly, that the operation of the plant…

Enter Parameter Mode by pressing the OPEN and CLOSE buttons simultaneously. The Set Parameters screen will appear on the LCD display. On the right of the display is the parameter number and below it the numeric value assigned to that parameter. Initially the value for parameter 1 is displayed. Using…
