4.6 MOUNTING BRACKET

Mark the hole positions using the wall bracket as a template per the
diagram.
Fit bracket securely onto wall before lifting appliance into position.
Drill the holes and fit the bracket ensuring it is level using suitable
high strength screws, with appropriate plugs or fixings, minimum
M10 size.
Always use assistance if required. Wear suitable cut resistant gloves
when handling the appliance. Ensure safe lifting techniques are used.
Do not lift the appliance by attached pipe-work or components.
When lifting the boiler ensure that the fixing elements and the wall
have a sufficient load-bearing capacity. Check the quality of the wall.

4.7 WATER CONNECTIONS

CAUTION: The hydraulic connections must be carried out respecting the flow and return marked on the boiler.
CAUTION: When tightening or loosening threaded connections, always use suitable tools as open-end spanners. Do
not use pipe wrenches, extensions or unsuitable tools that may cause damage or water leaks.
i
Install purges in the radiators and high points of the installation.
Heating Flow & Return
These connections are ¾ " for connection to 22mm pipe. Service valves should be installed at this position to allow the
boiler to be isolated for maintenance without the need to drain the entire system. The valves should be of sufficiently large
bore so not to restrict the heating circulation.
Single pipe heating systems are not recommended only a twin-pipe heating system should be used.
Drain Point
A drain point should be fitted at the lowest point of the system. It is not acceptable to drain the boiler through the safety
valve as debris and deposits will prevent correct operation of the valve.
The clearances around the boiler as shown above must be observed for
correct operation.
A minimum of 200mm clearance must be maintained underneath the boiler
to allow replacement of the heating elements if required. A minimum of
500 mm clearance must be maintained in front of the boiler to enable easy
access for servicing.
Ensure sufficient space to make all water connections including the outlet
pipes for the heating safety valve which should be routed to a suitable
discharge point.
