ELECTRICAL CONNECTIONS TO THE BURNER TERMINAL STRIP
(to be made by the installer)
FASTENING OF THE ELECTRICAL WIRES
All the wires, to be connected to the burner terminal strip (16, fig. 1) shall pass through the cable entries
(17, fig. 1), see the figure below.
Further prospective signals or controls can be connected to the burner terminal strip by presheared disk inserting
a common cable gland for the passage and the clamping of the leads. To ensure the IP 40 degree of protection
in compliance with EN 60529 close the passage holes of the cables and any unused entry leads with appropriate
disks.
NOTES
- Make a safe earth connection.
- Verify the burner stop by opening the boiler thermostat and the burner lock-out by darkening the photocell.

For supply at 230V make the triangle connection on
the pre-heater and on the motor (the original connec-
tion is “star” for 400V).
