Gas Fill and Prove Time
Gas fill and prove times are adjustable. There are two dip-switches located on the inside facia of
the Merlin 2000S labelled "Fill Time" and "Prove Time". They are factory set in the 'off' position.
Fill and prove time can be changed by turning the relevant dip switch to on position.
FILL TIME is the amount of time the gas valve is open to fill the gas line.
Off – 5 seconds
On – 10 seconds
PROVE TIME is the amount of time the system tests the gas line for any leaks.
Off – 30 seconds
On – 50 seconds
Once the settings has been changed please remove power from the fuse spur for 10 seconds.
On installation, this can be switched to the ON position if required. This will instruct the system
to leave the fans on and only shut off the gas supply on activation of the Emergency shut off
button(s).
Note: This option is not available if Fan Switch is not installed.
