JINCHW09 Rev A 12/05/14 

If a common flow and return is used, these should 
also  be  taken  from  diagonally  opposite  sides  of 
the boiler, and plugs inserted into the sockets not 
used. 
 
Systems  using  a  common  flow  and  return  to  the 
boiler  should  incorporate  an  injector  tee  on  the 
primary  return  connection  from  the  central 
heating pump (see diagram). 
 
 A  HIGH LIMIT  thermostat should  be  fitted  to  the 
gravity  flow  pipe  close  to  the  boiler  and  set  at 
90°C.  This  should  override  any  pump  control, 
switching the pump on and dissipating any excess 
heat around the radiator circuit. 
 
To prevent boiler corrosion due to condensation it 
is necessary to maintain the return water 
temperature above 45°C. This can be achieved by 
the use of a LOW LIMIT thermostat on the return 
pipe from the hot water cylinder, close to the 
boiler. The thermostat should make on 
temperature rise, preventing the circulating pump 
from operating until the gravity circuit is up to 
temperature.

N.B. An adjustable flue bend may be required for 
some installations.

 

 

If connecting to a stainless liner,

 a proprietary 

single wall flue adaptor will be required. It is 
recommended that a short length of flue pipe is 
connected before the liner. 
 

 

 

If connecting to an existing masonry

 chimney it is 

recommended that a flue forming pipe (short 
length of flue pipe) is used and the void between 
the flue forming pipe and the chimney is filled with 
vermiculite concrete.  
 
A suitable access hole will need to be made in the 
chimney breast to allow the back filling to be 
carried out and then filled and sealed once the 
installation is complete. 

 

 
Alternatively a connection can be made using a 
register plate although it will be necessary to allow 
access for fitting the flue pipe to the register plate, 
infilling with vermiculite concrete and sealing all 
joints.
