E1.4 Open Vent and Cold Feed Pipe.

 

 

Every boiler or group of boilers should have an open vent pipe and cold feed pipe installed between the boiler and 
the first water isolating valve. The minimum bore (mm) of these pipes per installation is shown in the table. The 
vent pipe must rise continually, any valve fitted between a boiler and the open vent pipe for maintenance 
purposes shall be of the 3 way type such that when closed to the vent pipe the boiler will be open to atmosphere. 
The vent pipe shall be protected against freezing where this might occur. See BS 6644 for detailed information on 
Open Vent and Cold Feed Pipes.

 

 

E1.5 Thermometer 

 

A thermometer complete with pocket should be fitted in the pipe work to indicate water flow temperature. See 
Figure E1.1.1 for typical position. 

 

E1.6 Drain Valves 

 

Each boiler has a 15mm NB drain valve fitted in the boiler return,  for draining the boiler only. The heating system 
in total should have drain valves as recommended by BS 6644. See Figure E1.1.1 for typical position. 

 

E1.7 Circulating Pump 

 

Each individual boiler is fitted with an integral circulating pump ensuring flow through the boiler and primary circuit. To 
ensure the correct flow through the boiler, there is a balancing valve fitted to the flow pipe within the boiler. This is factory 
set and must not be adjusted. 
One or more circulating pumps will be required to circulate water around the heating system. All pumps should be 
sited to facilitate servicing. It is important that when Fleet

 

boilers are used to replace boilers on an existing 

system, the system design must be modified acknowledging the performance of the integral circulating pump.. It is 
also important that the existing system be flushed through twice to remove any loose matter which may have 
accumulated. To protect the boiler heat exchanger, it is strongly recommended that a dirt/air separator is fitted in 
the return to the boiler. If in any doubt regarding the cleanliness of the system, a coarse filter should be fitted in 
the return pipe work to the boilers. 

E1.8 Minimum Water Flow Rates 

 

Minimum water flow rates are shown in table at beginning of Appendix E. These flow rates should be maintained 
through the boiler at all times whilst the boiler is firing. To prevent the boiler firing in the event of poor or no flow, 
the boiler is fitted with an integral flow switch. Particular attention should be paid to the restriction of external flow 
circuits during periods of low heat demand. 
Each boiler module is fitted with a flow balancing valve on the return pipe within the unit. This valve may require 
adjustment to ensure the correct flow through the boiler - refer to commissioning instructions Section  7.7 
 

 

E1.9 Waterside Pressure Drop 

 

The waterside hydraulic resistance (Pressure drop) is given in table at beginning of Appendix E. 

 

E1.10 Water Flow Controls 

 

The Fleet boiler is fitted with an integral circulating pump, which will shut off circulation 5 minutes after the boiler 
has ceased firing. 
Any external mixing valve / shunt pump or similar controls MUST always ensure that the minimum water flow rate 
as given in table at beginning of Appendix E is maintained. As a precaution, the Fleet boiler is fitted with a flow 
switch. The flow switch is designed to operate such that the boiler will shut down if insufficient flow occurs. 

 

E1.11 Frost Protection 

 

Consideration should be given to fitting an optional outside air sensor, to provide the necessary frost protection. 

 

E1.12 Unvented Systems 

 

Refer to Figure E1.1.1 on opposite page for typical layout of an unvented (Pressurised) Hot Water System. For 
system design refer to BS 7074 Part 2. In order to correctly size a pressurisation unit for any heating system the 
following parameters are required. 

1) 

Static height of highest component in system (metres) 

2) 

System volume. If this is not known, a general rule of thumb of 10litres/kW of installed boiler power 
can be used. 

3) 

Maximum flow temperature (°C) 

4) 

Maximum system hot working pressure, generally given in bar gauge. 

 

From the parameters given, Hamworthy Heating can size the pressurisation unit and also the expansion vessel.
