If the valve is being installed for use with a gas fired instantaneous (multipoint) heater or a combination boiler, an
OPC4100 system should be fitted. The PINK cartridge is factory fitted with a YELLOW flow regulator in the hot inlet port,
suitable for use with an 80,000 Btu rated combi boiler. If fitting to a system supplied by a 100,000 Btu combi boiler,
the regulator should be replaced by a OLIVE regulator. If fitting to a system supplied by a 120,000 Btu combi boiler,
the regulator should be replaced by a BLUE regulator. The replacement regulators are supplied as part of the system
components.
