- Page 2 DATA SECTION – Page 2 GENERALPotterton Flamingo room sealed appliances are auto-matically controlled and have been designed for combined systems, e.g. small bore or microbore central heating with an indirect domestic hot water supply which can either have pumped or gravity circulation. These boilers can also be used on a pumped central heating or domestic hot water only system.
- Page 3 1. All system should be designed so that the static head of the boiler is between a minimum 90mbar (3ft/w.g.) and a maximum. of 2.7bar (9Oft/w.g.), except for fully pumped systems where the cold feed is connected into the spare return tapping on the boiler in which case, the static head can be reduced to 1 ft/w.g.

- Page 5 Servicing is a simple matter as once the casing has been removed all parts that are likely to require servicing are easily accessible. SETTING UP Each boiler has to be adjusted once it is installed and this is a skilled job which should only be undertaken by suitably qualified Engineers. Potterton International offer this service on a changeable basis.
