When you expect not to use the boiler for a long period:
• Switch off the electricity supply to the boiler, by means of the circuit breaker;
• Shut off the gas supply cock connected to the gas inlet pipe and the cock connected to the supply cold water inlet
pipe (for pipes see Section 8 System Piping in the installation, operation and service instructions manual);
• Empty the water circuit, if there is a risk of freezing.
1. Every KAPPA R boiler is equipped with a block flue control. The control is designed to prevent the boiler from
running if exhaust products are escaping from the boiler draft control. If the blocked vent control prevents the
boiler from running, do not attempt to place the boiler in operation, shut the power off to the boiler, close the gas
supply and contact your service professional to fix the underlying problem.
2. Every KAPPA R boiler is equipped with a flame roll out control. The control is designed to prevent the boiler from
running if flames are pulled out of the burner tray of the boiler. If the flame roll out control prevents the boiler from
running, do not attempt to place the boiler in operation, shut the power off to the boiler, close the gas supply and
contact your service professional to fix the underlying problem.
