GENERAL

5 LOW HEAD AND LARGE SYSTEMS WITH EXTENSIVE PIPE RUNS - OPEN VENT

This arrangement is useful for large systems where radiators at the extremities are difficult to vent. This can lead to pumping over with conventional feed and vent arrangements.

The following conditions MUST be observed:

1.The top of the automatic air vent must be below the

cold water level.

2.The static water level (cold) must be at least 200mm above the top of the horizontal flow pipe, fitted as

shown. The vent connection MUST NOT be made immediately off the top of the boiler as venting is made less efficient.

3. The maximum practical length of 22mm cold feed pipe should be used in order to reduce the effective volume of hot system water expanding into the feed/expansion cistern to a minimum.

Note. The pump manufacturers' minimum requirements must be complied with.

All dimensions in mm (in.).

NB. Imperial dimensions are approximate

6 SEALED SYSTEM REQUIREMENTS

Notes.

a.The method of filling, refilling, topping up or flushing sealed primary hot water circuit from the mains via a temporary hose connection is

only allowed if

acceptable to the local water authority.

b.When installing the filling device, it must be

connected as shown to fully comply with the water regulations. This may involve the fitting of an additional WRAS approval isolator valve to the mains supply.

a. The installation must comply with the requirements of BS. 6798 and BS. 5449.

b. The installation should be designed to work with flow temperatures of up to 82 oC.

c. All components of the system, including the heat exchanger of the indirect cylinder, must be suitable for a working pressure of 3 bar (45lb/in2 ) and temperature of 110oC. Care should be taken in making all connections so that the risk of leakage is minimised.

2. Safety Valve

A spring loaded safety valve complying with the relevant requirements of BS. 6759 must be fitted in the flow pipe as close to the boiler as possible and with no intervening valve or restriction. The valve should have the following features:

(note direction of flow)

a.A non-adjustable preset lift pressure not exceeding 3bar (45lb/in2).

b.A manual testing device.

c.Provision for connection of a discharge pipe.

The valve or discharge pipe should be positioned so that the discharge of water or steam cannot create a hazard to the occupants of the premises or cause damage to electrical components and wiring.

3.Pressure Gauge

A pressure gauge covering at least the range 0-4 bar (0-60 lb/in2) must be fitted to the system. The gauge should be easily seen from the filling point and should preferably be connected at the same point as the expansion vessel.
