Connection to the central heating system
The boilers may be installed on either open vented or sealed fully pumped systems. The water system must
be properly vented and a double-feed indirect cylinder to the current specification in issue BS 1566 Part 1 for
double indirect cylinders is necessary where there is a combined hot water and central heating system.
During installation caution must be made on the need for a gravity heat-leak radiator or towel rail to dissipate
heat when the pump is off and the minimum load for this function.
The central heating system must be in accordance with BS EN 14336:2004: Heating Systems in Buildings.
