SYSTEM DESIGN

3.2 Heating System Design

3.2.1 General

The  installation  must  comply  with  the  requirement  of  BS  6798  and  BS  5449.  
Maximum water temperature is 82 ± 2°C.  The appliance is supplied with the flow 
and return connections terminating in 22mm copper pipe or 22mm compression 
fittings.
The pump head available for the central heating circuit is shown in Figure 11.
The sealed system models incorporate the following components:-
•      Heating pump - on the flow from the store.
•      Expansion vessel - 12 litres, pre-charged to 1.0 bar.
•      Pressure gauge 0 to 4 bar
•      Expansion relief valve - set to operate at 3 bar.

At  least  one  flushing  valve  should  be  fitted  at  the  lowest  point  in  the  system  to 
enable the water system to be drained. 

If  the  appliance  is  the  highest  point  on  the  heating  system  a  manual  air  vent  is 
provided above the heating pump.  However, if any point of the heating system is 
higher than the appliance we would recommend that an automatic air vent is fitted 
at the highest point in the system.  

Normal procedures for sizing heating circuit pipes should be used and the pump 
head available for the heating system is shown in Figure 11.    If all the radiators 
are  provided  with  thermostatic  valves  a  suitable  by-pass  should  be  provided  as 
normal on the heating circuit.

3.2.2 Sealed Central Heating System

The sealed heating system/appliance must only be filled by a competent person.
Full details are provided in Appendix A - Design/Installation details for the CA type 
backflow prevention valve assembly and anti-vacuum valve.  

Note:  Minimum  of  2  bar  mains  pressure  must  always  be  available  for  correct 
operation of CA devices.
