Examples of systems which require a bypass are:-

a) A system controlled by non-electrical valves e.g. mechanical thermostatic control valves both on the radiators and the hot water circuit.

b) A system using twin zone valves (e.g. Honeywell 'S' Plan) (Fig. 3).

c) A system using a 3 port divertor valve (Fig. 4) does not normally require a bypass therefore this system is recommended. The exception to this is where thermostatic radiator valves are used and then a bypass is required.

NOTE: For ‘S’ Plan systems the bypass flow circuit must be situated between pump and zone valves as option A shows (Fig. 2).

The bypass circuit can be:-

a) For all boilers a minimum of 6 metres of 22mm copper pipe, (measured between the boiler flow and return connections). It should be fitted with a lock shield valve opened at least 1 full turn or a proprietary bypass valve set to give a minimum flow rate of 8 litres/min (1.8 gal/min) (Option C, Fig. 1 & Option A, Fig.2).

b) A radiator fitted with lock shield valves. The radiator output should be a minimum of 800 watts (2,700 Btu/h). Typically a convector type radiator with an area of 3750 cm

(4 sq ft) is

adequate (Option B, Fig. 1).

c) Any circuit that provides the same operating conditions as option A or option B (Figs. 1 & 2).

3.1 Water Circulating Systems

1. The appliance is suitable for use with open vent fully pumped systems and sealed systems where additional control protection is required.

The following conditions should be observed on all systems:

• The static head must not exceed 30m (100ft) of water.

• The boiler must not be used with a direct cylinder.

• The boiler is fitted with a timed pump overrun that will operate for approximately 8 minutes.

• Drain cocks should be fitted to all system low points.

• All gas and water pipes and electrical wiring must be installed in a way which would not restrict the servicing of the boiler.

• Position isolating valves as close to circulating pump as possible.

Treatment of Water Circulating Systems

All recirculatory water systems will be subject to corrosion unless they are flushed and an appropriate water treatment is applied. To prevent this, follow the guidelines given in BS 7593 “Treatment of Water in Domestic Hot Water Central Heating Systems” and the treatment manufacturers instructions.

Treatment must involve the use of a proprietary cleanser, such as Sentinel X300 or X400, or Fernox F3 and an inhibitor such as Sentinel X100 or Fernox MB-1.

Full instructions are supplied with the products, for further information contact Sentinel (0800 389 4670) or Fernox (0870 870 0362).

Failure to flush and add inhibitor to the system will invalidate the appliance warranty.

It is important to check the inhibitor concentration after installation, system modification and at every service in accordance with the inhibitor manufacturer’s instructions. (Test kits are available from inhibitor stockists.)

For information or advice regarding any of the above contact Technical Enquiries 0844 871 1555.

3.2 Bypass Requirements

1. The boiler is fitted with a pump overrun device which allows the removal of residual heat from the boiler.

NOTE: The pump overrun will operate for approximately 8 minutes. The system design must therefore, always provide an open circuit for water to circulate between the boiler flow and return.

2. See information opposite “Examples of systems which

require a bypass are”.

3.0 System Details

3.3 Pipework

1. If this appliance is being fitted to a system containing plastic pipework, the flow switch kit part n

5107297

must be fitted.

2. The sizes of flow and return pipes from the boiler should be determined by normal methods, according to the requirements of the system.

3. An 11 °C (20°F) drop in temperature across the system is recommended.

4. In systems using non-metallic pipework it is necessary to use copper pipe for the boiler Flow and Return. The copper must extend at least 1 metre from the boiler and include any branches (Fig. 5). The copper pipe must not be insulated.

3.4 System Controls

1. For optimum operating conditions, the heating system into which the boiler is installed should include a control system.

2. Such a system will comprise of a timer control and separate room or cylinder thermostats as appropriate.

3. The boiler should be controlled so that it operates on demand only.

4. Operation of the system under control of the boiler thermostat only does not produce the best results.

5. A frost thermostat is fitted integrally to the appliance controls and will protect the boiler from frost damage by operating the burner when the water temperature in the boiler drops towards freezing point. The boiler will fire as necessary to maintain a temperature above freezing.

NOTE: The frost thermostat operates even if the boiler thermostat is in the OFF ('0') position and it is necessary therefore, if the system is drained, for the external electrical and gas supplies to be isolated. It is recommended that a label be affixed to the appliance to draw attention to the fact that the system has been drained.

3.5 Low Head Installation

For boilers up to 50,000 Btu/h output

1. Using a close coupled arrangement the minimum head is as shown in the diagrams (Figs. 6 & 7) subject to the following conditions:

a) The correct heat input. b) The pump being adjusted to give an 11

C drop

across the boiler. c) The pump must be fitted on the flow. d) The pump must be fitted in accordance with the

pump manufacturer's instructions. e) The open vent pipe must be taken up from a tee in

a horizontal section of the flow pipe.

Alternative Low Head Installation for all Solo 3 PFL

(Fig. 8)

2. If less height is available then a combined vent and feed pipe may be connected. This must be a minimum of 22mm diameter. It is recommended that an air separator is fitted when using a combined feed and vent pipe.

3.6 Sealed Systems (Fig. 9)

1. SAFETY VALVE - A safety valve complying with the requirements of BS 6283 Part 1 must be fitted close to the boiler on the flow pipe by means of a horizontal or vertically upward connection with no intervening valve or restrictions and should be positioned to facilitate testing. The valve should be pre-set and non-adjustable to operate at a pressure of 3 bar (45 Ibf/in2). It must be arranged to discharge any water or steam through a pipe to a safe outlet position.

2. PRESSURE GAUGE - A pressure gauge of minimum range 0-4 bar (0-60 Ibf/in

) with a fill pressure indicator must be fitted to the system, preferably at the same point as the expansion vessel in an easily visible position.

3. EXPANSION VESSEL - An expansion vessel complying with the requirements of BS 4814 must be fitted to the system by means of a connection close to the inlet side of the circulating pump in accordance with the manufacturers instructions, the connecting pipe being unrestricted and not less than 15mm (1/

in) nominal size. The volume of the vessel should be suitable for the system water content and the nitrogen or air charge pressure should not be less than the system static head (See Table. 1).

Further details of sealed system design can be obtained from BS 5449 and the British Gas publication entitled 'Specifications for Domestic Wet Central Heating Systems'.

4. FILLING POINT - A filling point connection on the central heating return pipework must be provided to facilitate initial filling and pressurising and also any subsequent water loss replacement / refilling.

The sealed primary circuits may be filled or replenished by means of a temporary connection between the circuit and a supply pipe, provided a ‘Listed’ double check valve or some other no less effective backflow prevention device is permanently connected at the inlet to the circuit and the temporary connection is removed after use.

The filling method adopted must be in accordance with all relevant water supply regulations and use approved equipment.

Your attention is drawn to, for GB: Guidance G24.2 and recommendation R24.2 of the Water Regulations Guide. for IE: the current edition of I.S. 813 “Domestic Gas Installations”.
