Installation  

 
 
 

1.

 

Release  the  outer  casing  by 
removing  the  screws  on  the 
underside of the casing. 

 
 
 
 
 
 
 
 
 
 
 
2.

 

Secure  the  heater  to  the  wall 
using fixings suitable for the wall 
type.    Ensure  the  chassis  is  flat 
to  the  wall  and  level.  If 
necessary 

use 

packing 

to 

compensate  for  an  uneven  wall 
surface.  Maximum recommended 
installation  height  is  2.1  metres 
to the underside of the heater. 

 
 
 
 
 
3.

 

Connect the heating  system flow 
and  return  pipes  to  the  heater 
pipe  work.    Do  not  use  soldered 
fittings  to  the  heater  pipe  work 
as  the  heat  generated  could 
damage  internal  wiring 

and 

components.  We recommend the 
use  of  full  flow  service  valves.  
The  valves  should  be  accessible 
after 

completion 

of 

the 

installation.    Check  for  water 
leaks.  Vent any trapped air from 
the heating system.
