5-3.1 Service Access
External Wall Mounted Boilers have a large hinged front door that gives access to the
Control Panel and enables all routine servicing to be carried out without the necessity of
removing main case or flue. The door can be lifted off in windy conditions.
A large bolted service door is provided on the front of the heat exchanger giving easy
access to the baffles and combustion chamber.

The flow and return connections are on the top of the Boiler heat exchanger - 1” female
BSP. The standard arrangement is to connect through the back panel as shown in fig.
