Note. 

Minimum static head

requirements with limit thermostat
set at 110ºC (230ºF) is 2.5m.

The example illustrated is intended
as a general guide only.  Caradon
Ideal Limited
 will be pleased to
advise on specific applications.

Design and minimum flow rate
tables are shown Frame 8.

System Design

Recommendations relating to water system design are
contained in BS. 5410: Part 2 and BS. 6880.

System design must allow for adequate internal circulation
within the boiler and sufficient heat release from the boiler
body during and immediately after burner firing.  Heating and/
or hot water controls should be interlocked electrically with the
burner, to prevent firing when the system does not demand
heat.

Depending on system design it may be necessary to interrupt
electrical supply to the burner before any mixing valves are
completely closed to the boiler flow.  This will dissipate residual
heat.  Also a pump overrun of at least 5 minutes is required on
plant shutdown to avoid interference trip out of the overheat
thermostat.  If system return temperature remains below 30ºC
for most of the heating period some protection from
condensation is required.

Please contact Caradon Ideal Limited for further information.

SYSTEM DESIGN CONTINUED

Example of Installation

The example below does not cover all the possible cases of
use.  It is only aimed at drawing attention to the basic rules
which must be complied with.  In all events, comply with
applicable codes of practice and national or local regulations.

Example shows a sealed system with domestic hot water
production via independent calorifiers.

Typical Sealed System Example

A shunt pump sized on the minimum flow rate required MUST
be fitted.  Provided adequate heat dissipation can be achieved
at all times the shunt and DHW primary pumps only may run
on during the overrun period allowing the heating pump to be
switched off.  This example assumes the DHW primary pump
flow rate required is less than that required for the shunt pump.
