Checking the gas rate
▶ The gas rate should be measured at the gas meter after the appliance
has been operating for a minimum of 10 minutes at maximum output.
▶ See Technical data section on page 8 of this manual for gas rates and
CO/CO
2
ratios.
▶ Where a gas meter is not available (e.g. L.P.G.) the CO/CO
2
must be
checked.
▶ Gas rate must be checked with the appliance in service, maximum
output mode.
6.5.4
Gas rate testing
▶ Ensure all other gas appliances are isolated.
▶ Set the appliance to maximum output by pressing the
button
for at least 5 seconds.
The chimney sweep symbol
will be displayed at the top of the
screen and the word “Max” will flash at the bottom of the screen. The
appliance will ramp up to maximum output in 30 to 35 seconds.
▶ Ensure that the appliance has stabilised at maximum output.
▶ Carry out Gas rating procedures as described in current edition of the
“Essential Gas Safety”.
▶ If pressure and gas rate are satisfactory press the reset or return
button and the appliance will return to normal operation.
– If left in the service mode the control will return to normal
operation after 15 minutes.
6.5.5
Checking for leaks during operation
▶ Use an approved leak detector to check all connections for possible
leaks. The product must be certified as a gas leak testing agent.
▶ Do not allow the product to come into contact with the electrical
wiring.

Domestic hot water
Controlling the hot water temperature (optional integral diverter
valve kit fitted):
The hot water temperature can be set to between approximately 40°C
and 60°C using the DHW temperature control.
Domestic hot water pre-heat (optional integral diverter valve kit
fitted):
Pre-heat reduces the time taken to produce hot water at the tap and is
controlled by the ECO button (
).
▶ Press the
button to select either state:
– When Pre-Heat is displayed, the appliance will be in pre-heat
mode (the hot water cylinder temperature will be maintained
around the setpoint).
– When ECO is displayed the appliance will be in Economy mode
and Pre-Heat will be off.
Maximum output mode
▶ The diverter valve will go to mid position in chimney
sweep mode. A hot water outlet can be opened to
prevent the appliance from shutting down due to high
temperature during testing.
