General Restrictions

a.   The highest hot or cold water draw off point should not exceed 10 metres above the 

Pressure Reducing Valve.

b.    An ascending spray type bidet or any other appliance with a Class 1 back-syphonage 

risk requiring a type A air gap should not be used.  

c.    Viessmann Vitocell 200 Cylinder should not be used where steam is the primary 

heating medium, or in a situation where maintenance is likely to be neglected.

d.   Unvented cylinders are not suitable  for use with solid fuel boilers.
e.   if the supply to the mixer fittings (other than a dual outlet type) is not taken 

from the balanced supply the system will become over pressurized and cause the 
pressure relief valve to discharge.  Over time this could also cause the premature 
failure of the appliance itself which will not be covered by the warranty,

f.     In larger properties with a number of bathrooms/en-suites and long pipe runs 

we would recommend that the balanced cold supply is provided with its own 
pressure reducing valve and is not taken from the balanced cold connection on the 
combination valve.  In this case it will also be necessary to fit a small expansion vessel 
on the balanced cold water system to accommodate the pressure rise caused by the 
increase in temperature of the balanced cold water.

g.   Check the performance requirements of the terminal fittings with regard to flow/

pressure are suitable.

Shower Fittings

Aerated taps are recommended to prevent splashing. Any type of shower mixing valve 
can be used as long as both the hot and cold supplies are mains fed.  However, all 
mains pressure systems are subject to dynamic changes particularly when other hot 
and cold taps/showers are opened and closed, which will cause changes in the water 
temperature at mixed water outlets such as showers.  For this reason and because 
these are now no more expensive than a manual shower we strongly recommend 
the use of thermostatic showers with this appliance.  These must be used in 3 storey 
properties where the impact on pressure/temperature of opening another tap in the 
system is greater than normal. The shower head provided must also be suitable for 
mains pressure supplies.

Pipe Layout

In all mains pressure installations it is important 
to  remember  that  the  incoming  cold  supply 
must be shared between all terminal fittings.  It 
is important that a 22mm supply is brought to 
the appliance and a 22mm take-off is continued 
at least to the bath.  If there are two baths, 28mm 
pipework should be considered.  One metre of 
smaller diameter pipework, or flow restrictors, 
should be provided on the final connection to 
all outlets so as to balance the water available.  
In any event the distribution pipework should 
generally be in accordance with EN806:1.

Plastic Pipework

This  appliance  is  suitable  for  use  with 
plastic  pipework  as  long  as  the  material 
is  recommended  for  the  purpose  by  the 
manufacturer and is installed fully in accordance 
with their recommendations.

Secondary Hot Water Circulation

Some models are fitted with a secondary return 
tapping  as  standard  (see  table  1  for  details).  
If  fitted,  an  extra  expansion  vessel  may  be 
necessary.  A non-return valve MUST be FITTED 
near the return connection.  No valve or terminal 
fitting  should  be  installed  between  the  non 
return valve and the cylinder. (See schematic 
arrangement on page 13.)
