Page 2: General Information
General information Operating principles The CG is a wall-mounted condensing boiler with stainless steel counter flow twin heat exchangers (the CG 60 has a single heat exchanger), pre-mix gas burner and integral flue products fan (refer Figs 1 and 2). When operating in condensing mode with a flow of 50°C and a return of 30°C, it will give efficiencies of up to 109.5% (ncv). -

Clyde recommend that a permanent means of room ceiling exceeds 40°C. filtration be fitted into the return pipework, such as a For a single 60 kW boiler with a Type B powered flue, the sludge trap, hydrocyclone or full flow duplex filters. -
Page 6: Installation Requirements
Installation requirements Heat exchanger hydraulic resistance The CG boiler has a high resistance heat exchanger. A Grundfos or DAB pump is supplied as an integral part of the boiler to overcome this resistance and ensure a constant water flow through the boiler. This is not a system circulating pump. -

- Page 12 Note that the maximum electrical current that can be switched by each EBC is 2A, so additional relays (not supplied by Clyde) may be needed. The arrangement shown in Fig 8 will heat a single heating circuit, directly compensated on the common boiler flow temperature.
- Page 13 Hydraulic system design and control PRT or RC Master PH KR Fig 8 Single boiler with one heating zone and optional DHW calorifier connected to the “High” temperature side of the LVH The DHW calorifier is directly controlled from the boiler via the 3-port diverting valve (DV) and DHW sensor (FB). The PRT or RC (Programmable Room Thermostat/ modulating control) gives time control of the heating circuit (the RC also gives time control of the DHW).
