1. OPERATION OF THE APPLIANCE The purpose of the Intergas Rapid wall mounted gas fired boiler is to heat water and to supply it to the central heating CH system and the domestic hot water DHW taps The heat exchanger comprises of two separate systems for central heating and DHW The appliance is fitted with a modulating control This means that the power is adjusted in line with the required heat The boiler controller responds to each call for heat from the heating or the DHW system by igniting the burner and monitoring the flame 1 1 Operation of the central heating The call for heat arises as a result of the room temperature being lower than the temperature set on the room thermostat If at that time the appliance does not have a call for DHW the appliance comes on in central heating mode The central heating temperature control modulates on the basis of the set central heating supply temperature This means that when the desired central heating supply temperature is approached the appliance adjusts the power The pump for the central heating has a post purge period of 1 minute The post purge period may be changed if desired The pump runs automatically for 10 seconds once every 24 hours to prevent blocking 1 2 Operation of domestic hot water supply The DHW system is started automatically as soon as more than 2 litres of water per minute are drawn During delivery of hot tap water no heat is supplied by the appliance to the central heating syste2. radiators and or an air bleed in the piping e Check that after bleeding the system the water pressure in the installation is still between 1 and 2 bar if not repeat the procedure If the system has to be filled more frequently than a few times a year notify your installer since this means that there is probably a leak 5 2 Domestic hot water supply Pressurise the DHW part of the appliance by opening the main tap and or the inlet assembly Remove air from the appliance and the pipe work by opening a hot water tap Leave the tap open until all the air has disappeared from the appliance and the pipe work Close the hot water tap Check the connections for leakage 5 3 Frost protection To prevent freezing of the condensate drain the appliance should be installed in a frost free room The appliance is equipped with frost protection which as long as mains current is present switches on the CH pump and if necessary the burner when the heat exchanger temperature falls too far NB If an internal or external frost thermostat has been installed in the system and connected to the appliance it is not active when the appliance has been switched off at the operating panel on service display 6 MAINTENANCE The appliance can be cleaned with a damp cloth Do not use aggressive or abrasive cleaning agents or solvents The appliance and the installation should be checked and where necessary cleaned annually by a registered installer The s
