5 Burner Control Panel
5.1 Burner Control Panel
The burner control panel is located on the upper front part of the red burner cover.
This control panel is used by the Installer or Grant Service Engineer to check and set the burner and boiler settings during commis-
sioning or servicing.
The burner control panel display shows the following information:
Temperature Set Point
The set point is set by the Installer, during commissioning, using either button 1 or 2 (as shown below) within the range 55°C to 75°C.
Refer to Figure 5-1.
Typically it will be set to 70-75°C. This is the ‘target’ temperature setting about which the modulation of the boiler output will operate.
•
5°C below the set point, the boiler is in 100% power mode.
•
5°C above the set point, the boiler has reached minimum output.
The set point is NOT the temperature at which the burner stops. The maximum boiler temperature at which the burner will cut out is
factory set in the burner control settings. This can, if required, be adjusted by the installer or Grant service engineer.
Boiler System Water Temperature
This is the temperature of the water in the boiler. Refer to Figure 5-2.
NOTE
When the burner cuts out, the temperature will continue to rise as the heat from the flame is transferred to the system
water in the boiler.
