RECTANGULAR BRATT PANS GAS TYPE “BR8G080I - BR8G080I.M” “BR9G090I –
BR9G090I.M” “BR1G120I – BR1G120I.M” “BR1G150I – BR1G150I.M” “BR1G160I –
BR1G160I.M” “BR1G200I – BR1G200I.M”
3 CONVERSION TO OTHER TYPES OF GAS
THE TRANSFORMATION TO A DIFFERENT TYPE OF GAS MEANS:
the replacement of the main burner nozzles;
primary air adjustment;
the replacement of the 'nozzle on pilot burners;
control inlet pressures
3.1 REPLACEMENT OF INJECTORS FOR MAIN BURNERS
The device must be operated with nozzles provided for its nominal heat input (See.tab. " GAS DATA ").
To access the nozzle remove the front panel bath.
Disconnect and remove the ramp nozzle through the mounting screws.
Use a spanner to unscrew the nozzle SW13 ((FIG. "MAIN BURNER - PRIMARY AIR REGULATION") and
replace it with a suitable one (See.tab. " GAS DATA ").
All nozzles necessary for the various types of gas are contained in a bag provided with
the apparatus. The nozzles are identified by marking of the diameter in 1/100 mm.
Perform a leak test (with leak detection spray or foam NON corrosive solutions) at the
connection point of the ramp to the main copper
3.2 REGULATION OF PRIMARY AIR FLOW
Primary air can be considered correctly adjusted if no flame lift is ensured when the burner is cold and the
injector lights when the burner is hot..
The distance “H” (FIG.” MAIN BURNER - PRIMARY AIR REGULATION “) recommended for primary air
regulation is indicated in table ” GAS DATA”.
3.3 REPLACEMENT OF INJECTORS FOR PILOT BURNER
To access the pilot nozzle to remove the front panel bath.
Loosen the locking screw and replace the nozzle with the appropriate one. (See .tab. " GAS DATA ").
AT THE END:
Execute the control inlet pressures as described " CONTROL OF THE GAS INLET PRESSURE "
