This system is unlikely to require a By-pass unless all radiators are thermostatically controlled

Water Circulating Systems

The appliance is suitable for use with fully pumped open vented systems (small bore and micro-bore), gravity domestic hot water with pumped central heating systems and sealed systems. The following conditions should be observed on all systems:

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

water.

The boiler must only be used with an indirect

cylinder.

Drain points should be fitted to the lowest points in

the system.

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

Position isolating valves as close to circulating pump

as practicable.

For fuel economy and best boiler performance, the

system should be designed so that gravity circulation

does not take place in the heating system when the

pump is not running.

Treatment of Water Circulating Systems

For optimum performance after installation, this boiler and its

associated central heating system must be flushed in

accordance with the guidelines given in BS7593:1992

“Treatment of water in domestic hot water central heating

systems”.

This must involve the use of a proprietry cleanser, such as

BetzDearborn’s Sentinel X300 or X400, or Fernox’s Superfloc. Full

instructions are supplied with the products but for immediate information please contact BetzDearborn on 0151 420 9563, or Fernox on 01799 550811. For long term protection against corrosion and scale, after flushing it is recommended that an inhibitor such as BetzDearborn’s Sentinel X100, or Fernox’s MB-1 or Copal is dosed in accordance with the guidelines given in BS7593:1992.

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

BYPASS REQUIREMENTS

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 3 minutes. The system design must therefore always provide an open circuit for water to circulate

between the boiler flow and return.

If a system has an open circuit a bypass is not required.

A system using a 3 port diverter valve does not normally require a bypass and therefore this system is recommended. The exception to this is where all radiators in the system are fitted with thermostatic valves, in which case a bypass would be required. However, if one radiator in such a system was fitted with 2 lockshield valves a bypass would not be required.

A system controlled by non-electrical valves e.g. mechanical thermostatic control valves both on the radiators and the hot water circuit and systems using twin zone valves (e.g. Honeywell 'S' Plan) will require a bypass.

The bypass circuit can be:A) A minimum of 9 metres of 22mm pipe (measured between the boiler flow and return connections). It should be fitted with a lockshield valve opened at least 1 full turn to give a minimum flow rate of 8 litres/min (1.8 gal/min).

B) A radiator fitted with lockshield 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 cm2(4ft2) is adequate.

C) By including an automatic bypass valve in the system (see diagram).

D) Any circuit that provides the same operating conditions as option A or option B.

System Controls

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

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

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

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

Pipework

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

It is recommended that the system is designed for an 11 °C (20°F) drop in temperature across the system.

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. The copper pipe must not be insulated.

Fully Pumped, Open Vented Systems

Low Head Installation

Using a close couple arrangement the minimum head is as shown in the diagram, subject to the following conditions:

1) The correct heat input.

2) The pump being adjusted to give an 11oC drop across the boiler.

3) The pump must be fitted on the flow.

4) The pump must be fitted in accordance with the

pump manufacturer's instructions.

5) 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 2 RS

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.

SAFETY VALVE

A safety valve complying with the requirements of BS 6750 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.

PRESSURE GAUGE

A pressure gauge of minimum range 0-4 bar (0-

60 Ibf/in2) 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.

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 (1/2in) 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.

Further details of sealed system design can be obtained from BS 5449: Part 1 and the British Gas publication entitled 'Specifications for Domestic Wet Central Heating Systems'.

FILLING POINT

A filling point and an approved stop valve to BS 1010 must be fitted at low level and the method used for filling the system should be approved by the local water undertaking. For further details see BS 6798.

MAKE UP SYSTEM

A method of replacing water lost from the system should be provided either by means of a make up vessel of not more than 3 litres (5 pints) capacity, mounted above the highest point of the system, or by pre-pressurisation of the system.

VENTING

A method of venting the system during filling and commissioning must be provided by fitting automatic air vents or by venting manually.

HOT WATER STORAGE

The hot water storage vessel must be of the indirect coil type. All components used in the system must be suitable for operation at 110OC (230OF) and at the pressure allowed by the safety valve.

Gravity Systems

When the boiler is to be installed to an existing or new gravity domestic hot water and pumped central heating

system, the following considerations should be given

to the design of the gravity domestic hot water flow

and return pipes.

The minimum circulating head should not be less

than 1m (3ft) with a maximum horizontal run of

3m (10ft) when using 28mm pipes. Smaller pipe

sizes and longer horizontal runs are acceptable with suitably increased circulating heads.

The system must be designed to prevent

reverse circulation.

Pipes should be laid to maximum fall avoiding

points of possible air lock.

If the domestic hot water temperature is controlled by a cylinder thermostat and zone valve, it is recommended that a bypass is installed in the gravity circuit. One method is to install a bathroom radiator, fitted with two lock shield valves. Mechanical valves which allow the boiler to operate when the valve is closed should not be used.

Note: If the above conditions cannot be met, then pumped primaries must be used.

See page 25 for wiring of boiler when installed with gravity hot water.

SITE REQUIREMENTS

Location

The appliance may be fitted to any suitable wall with the flue passing through an outside wall and discharging to atmosphere in a position permitting satisfactory removal of combustion products and providing an adequate air supply. The appliance should be fitted within the building unless other-wise protected by a suitable enclosure ie. garage or outhouse. The appliance may be fitted inside a cupboard provided that ventilation requirements and combustible material standards are adhered to.

If the appliance is fitted in a room containing a bath or shower reference must be made to the Current I.E.E. Wiring Regulations and Building Regulations. If the appliance is to be fitted into a building of timber frame construction then reference must be made to the current edition of Institute of British Gas Engineers Publication IGE/UP/7 (Gas Installations in Timber Framed Housing).

Recommendations for flues are given in BS 5440 Pt1.

Clearances

A flat vertical area is required for the installation of the

boiler measuring as shown. A space above

the boiler should also be left clear as

indicated by the dotted lines.

These dimensions include the necessary clearances around the appliance for case removal, spanner access and air movement. Additional clearances may

be required for the passage of pipes

around local obstructions such as joists

running parallel to the front face of the

appliance.

If fitted inside a cupboard the clearance of 300mm shown is only necessary when the cupboard door is open. A clearance of 5mm (3/16in) is required from the front of the casing when the door is closed.

NOTE: On gravity applications a clearance of 80mm (31/8 in) is required from the top panel.

Flue Position

The following guide lines indicate the general requirements for siting balanced flue terminals.

If the terminal is fitted within 1 metre (39in) of a plastic gutter, within 500mm (191/2in) of a painted eave or a painted gutter, an aluminium shield of at least 1 metre (39in) long should be fitted to the underside of the gutter or painted surface. An air space of 5mm (3/16in) should be left between shield and gutter.

If the terminal discharges onto a pathway or passageway, check that combustion products will not cause a nuisance and that the terminal will not obstruct the passageway.

If the outer surface of an outside wall is of combustible material, it should be protected by fitting a noncombustible plate so that it extends not less than 50mm (2in) around the terminal.
