yourself with:

● how to isolate the appliance from the gas, water

and electricity supplies;

● the appliance controls.

2.2 APPLIANCE CONTROLS (see fig. 1)

The appliance controls are situated on the front of
the appliance. The appliance has a mode switch,

positions:

● OFF/RESET (0)

status indicator should be “green” if the status
indicator is flashing “red” refer to 3.2.

When a hot water outlet (tap) is opened, the appliance
will go through an ignition sequence, whereby the
burner will light.

If the appliance fails to ignite during the ignition
sequence, allow a period of two minutes before re­setting.

To adjust the outlet temperature of the appliance
turn the thermostat knob clockwise to increase or
anti-clockwise to decrease.

When the appliance reaches the set temperature,
the burner will modulate to ensure temperature
stability.
