DANGER
Electrical Shock Hazard
Disconnect electric before service.
Heater must be properly grounded.
Failure to follow these instructions can result in death or electrical shock.
Connect to the electrical supply using a 3 pin plug via a locally mounted double pole fused switch having a minimum disconnection of 3 mm on each pole. This switch should be fused to 3 amps. The burner is fused at 2 amps. There are no control connections in the standard burner. Control is affected by interruption of the main power inlet. See Page 55, Section 13.1 through Page 56,
Section 13.4 for the external wiring details for the single- burner, double linear and multiburner heater systems.
All wiring must comply with current wiring regulations and any local regulations which may apply. Always switch off the supply to the burner and disconnect by removing the plug before removing the burner side panel.
