1.18 Gas side resistor, temperature of output flue When faced with any fault (contactor, temperature swings, gases interruption of current, other faults), or when the pumps are stopped (protection pumps, etc.) the burner should switch off. The system should do this automatically. Carry out the electrical wiring taking into account all the Full Load above-mentioned information.
1.22 Fire prevention regulations for the boiler above 40°C before starting the pumps, the circulation pump room and the burner should operate contemporaneously. − Start the burner (carrying out the commands described in The RTT boilers should be positioned and oriented carefully and the burner's instruction manual).
1.27 Checking the safety limit thermostat Annual checks The annual checks should be carried out by technicians before the start of the season. The flue gases pipe and the relative pipes need to be cleaned before requesting the intervention of tech- nicians for the annual checks.
1.30 Connection of the burner door and the 1.31 Dimensions of the connection flange of the burner burner Burner door RTT 29-39 Fix the burner without leaving any empty space between the front door and the burner head. Cover all the connection points with insulating material to prevent leaks.
1.33 Removal of flue gases The design of the flue gases discharge system should be carried out following current standards. The flue should be rigid, completely air-tight, heat resistant, as well as resistant to condensation and mechanical stresses. If done incorrectly, the smoke pipe can increase noise or con- densation could form inside it, compromising the boiler's per- formance.
