INSTALLATION, COMMISSIONING & SERVICING INSTRUCTIONS
1.
1.1
JANUS 6/30 is an open flued gas fired circulator designed for floor or wall mounting, which can generate up to
64.8 litres per hour (14.3 gal/h) of hot water. It is suitable for use in a gravity fed circuit serving a hot water storage
cylinder (tank) and may be used efficiently with indirect storage systems or, in soft water areas, direct systems. Indirect
systems are preferred; direct systems should be used only when recommended by the local water company.
1.2
The gas supply to the main burner is controlled by a multi-functional gas control valve. The main burner operates in
conjunction with a permanent pilot burner and a thermoelectric sensing device. Pilot ignition is by means of a Piezo unit.
1.3
JANUS 6/30 pilot burner contains an Atmospheric Sensing Device which is able to detect a reduction in the oxygen
content of the combustion air to the appliance under adverse conditions, and will cause the pilot burner to be
extinguished. The appliance must then be re-ignited in accordance with the Ignition Instructions.
