INSTALLATION
BEFORE STARTING THE BURNER ALWAYS CHECK THE FOLLOWING:
- Burner and control unit have a proper earth connection.
- The on-burner nozzle has a flow-rate suitable for the boiler.
- The nozzle holder is fitted with the "O" marking facing upwards
- That there is fuel in the tank and the gates are open.
- The fuse on the electrical circuit is rated.
- The room and boiler thermostats are set to the desired temperature.
- The switch on any room thermostat is set.
- The air adjustment screw allows the throttle valve to open.
START-UP
- Reset by acting on the push-button.
- Power up by turning the main switch to ON. After the pre-ignition time has elapsed the
burner starts running and stays on until the temperature set on one of the control devices
causes the latter to trip (boiler thermostat, room thermostat etc.). During routine operation
the burner only shuts down when a control device is tripped.
N.B. If the burner fails to start up check that the pump has been primed: if it has not, act ma-
nually by undoing the gauge attachment screw and then screwing it back in as soon as you
notice fuel exiting the hole.
