1. Unlock the front access panel
Unlock and lower the front access panel using the
keys supplied. The keys come cable tied to the
back of the heater.
2. Fix unit to wall or ceiling
Fix the unit to the ceiling or wall via suitable
xings. If tted to suspended ceilings or similar
then suitable means of support such as threaded
rods or chains must be used.
3. Connect the pipes
Connect the heating system ow and return
pipes to the heater pipe work. Pipe entry/exit can
be made through either the back of the unit or
by using the pipe knockouts on the bottom of
the unit. Do not use soldered ttings to connect
the heater pipe work as the heat generated may
cause damage to internal wiring and components.
Compression ttings should be used. Pipework
must only enter in intended cut outs or knockouts
on the header connection side of the heater.
Note: 15mm pipework suitable for heating
outputs up to 12kW, 22mm should be used
where output exceeds 12kW (this is subject to
compliance with CIBSE recommendations).
Installation
Note: The system must be ushed prior to tting
this heater. Failure to comply with this may effect
the warranty.
Isolating valves must be tted. We recommend the
use of full-ow service valves. The valves should
be accessible after completion of the installation.
We also advise the tting of an air vent at the
highest point on either the ow or return pipe
to remove any air trapped within the system.
Valves must have the ability to regulate ow for
balancing.
4. Open the service valves
Having lled the heating system with water, open
the full ow service valves and check for water
leaks. Remove any trapped air from the unit via
the built in bleed screws as shown in the diagram
