  • Page 44: Commissioning Checklist

    COMMISSIONING BOILER CHECK LIST A suggested method of commissioning the boiler, actual method can vary according to the boiler make type and the installation. The boiler must always be installed , and commissioned by an qualified gas technician. The installer certifies that this Boiler has been installed to the manufacturer’s instructions, has been filled, commissioned and is ready for use. No. Description ✔ when done Read carefully the instruction manuals supplied with this boiler. BEFORE INSTALLING THIS BOILER FLUSH OUT THE PIPES UNTIL CLEAN WATER IS ACHIEVED. Turn off all services to this boiler - water, gas and power. Install the boiler as shown in the instructions following and connect all services. Turn on water to fill system, check for leaks regularly and bleed air from all points. Bleed the air from all the pumps in the system, and rotate the impeller shaft Check that all radiators valves are open, all lock shields remove the thermostatic valve heads, fully open. Turn ON gas, bleed air out at the isolation valve union. Reseal and check for gas leaks. Turn gas OFF. Turn electricity on at the power point. At the boiler front panel set the temperature setting to the lowest setting, switch boiler to ON position. The “Power on” Indicator should light. Turn the boiler off at the front panel. Turn the room thermostat to the manual ON position set the temperature to a high level so that it do es not switch off during the commissioning phase. The thermostat will unusually click and shows an Indicator in the window. Switch the boiler ON at the boiler front panel control. Boiler should start fan, pump and ignite gas. If it fails first few times this may be just residual air In the gas line. A noisy water pump indicates there is air in the water pipes. Boiler lights and heats the water. Check gas flame is the correct colour and for gas and water leaks as the system heats up. Check that heat is going to all radiators through the manual or thermostatic first and return via the lockshield valve. If not STOP fix NOW and any leaks. Allow the boiler to heat up to the set temperature and switch off. Re-adjust the boiler temperature to a mid temperature point. CAUTION, If this is connected to a floor heating system. The boiler should re light and ...
