5-1.2 Heating Connections

The flow and return connections may be diagonally opposed to give maximum flow
through the Boiler but this is not essential for satisfactory operation.
If the design of the heating system calls for flow pipes smaller than the Boiler flow
tappings, the reduction of the outlets should be made by using excentric reducing
sockets to ensure that all air can vent from the top of the Boiler waterway.
5-1.3 Connecting Control Panel
Select and Option Boilers are despatched with the Control Panel fitted. The phials of the
two thermostats are inserted vertically into the pockets situated on either side on the top
of the Boiler heat exchanger, see fig. 5-1c.
The mains electricity supply, preferably from a spur switched and fused 5 amp socket
should enter the Boiler casing through one of the holes or knockouts provided.
A plug is provided for connection to the mains supply. The plug fits into the mains
connection on the underside of the Control Panel.
Select - The Burner has cable and plug that connects to underside of Control Panel.
Option - The Burner is prewired to the Control Panel.
5-1.4 Oil Connection
All Floor Standing Boilers are supplied with a pump set for single pipe oil system.
