3.0 System Details - Page 6

3.1 Water Circulating Systems

1. The appliance is suitable for open vented systems which

are either fully pumped or pumped central heating with

gravity domestic hot water.

2. An optional overheat thermostat kit is available where

additional control protection is required and for sealed

system applications. This must not be used on gravity

systems.

3. The following conditions should be observed at all

times: •The static head must not exceed 30m (100ft)

of water.

•The boiler must not be used with a direct

cylinder.

•Drain cocks should be fitted to all system low

points.

•All gas and water pipes and electrical wiring

must be installed in such a way that they do

not restrict the servicing of the boiler.

•Position isolating valves as close as possible

to the circulating pump.

3.2 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 proprietary

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 BetzDearbom (0151

420 9563) or Fernox (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 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 manufacturer’s instructions. (Test kits

are available from inhibitor stockists.)

For information or advice regarding any of the above contact

the Baxi Helpline.

3.0 System Details - Page 7

3.3 Pipework

1. The sizes of the flow and return pipes from the boiler

should be determined by normal methods according to the

requirements of the system.

2. It is recommended that the system is designed for an

11°C (20° F) drop in temperature across the system.

3.4 System Controls

1. For optimum operating conditions, the system in which

the appliance is installed should include a control system.

2. Such a system would comprise a timer control and a

separate room and/or cylinder thermostat as appropriate.

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

demand only.

4. It is not economical to rely on the boiler thermostat to

control operation of the system.

3.5 Fully Pumped System (Fig. 3)

1. The sizes of the system pipes should be determined by

normal methods.

2. The open vent pipe should be a minimum of 22mm and

must rise continuously to a point above the teed and

expansion tank.

3. The flow pipe from the boiler may form part of the vent

pipe. No part of the open vent should contain a valve.

3.0 System Details - Page 8

3.6 Overheat Kit & Sealed Systems

1. An overheat thermostat kit is available to facilitate the

installation of a Bermuda Inset 2 boiler to systems

incorporating a combined feed and vent and to flats and

dwellings where the building design prevents the boiler vent

pipe rising continuously to the feed and expansion tank.

(This must not be used on gravity systems.) Baxi Part N°

234885.

2. The boiler can be applied to a sealed system with the use

of the overheat kit.

3. Information regarding the application of the overheat

thermostat is included with the kit.

3.7 Storage Systems

1. For information regarding the use of a Bermuda Inset 2

boiler with a storage system, contact the appropriate storage

system manufacturer.

3.8 Pumped Heating & Gravity Hot Water (Fig. 4)

1. The sizes of system pipes should be determined by

normal methods.

2. The gravity flow pipe should rise vertically as close as

possible to the boiler, avoiding sharp bends and tight

elbows.

3. The open vent pipe should be a minimum of 22mm and

must rise continuously to a point above the feed and

expansion tank.

4. The flow pipe from the boiler may form part of the vent

pipe.

5. No part of the open vent should contain a valve.

6. The brass injector tee must be fitted to the boiler return

on all systems incorporating a gravity circuit.

7. The circulating head should not be less than 1 m (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.

8. The gravity circuit should be designed with a minimum of

restriction, avoiding possible air traps and long horizontal

runs.

9. The system should be designed to prevent gravity

circulation in the heating system when the pump is not

running.

4.0 Site Requirements - Page 9

4.1 Builders Opening (Fig 5)

1. The boiler unit is designed to fit within a standard builders

opening, the minimum dimensions of which are as shown.

Height 584mm (23in)

Width 584mm (23in)

Depth 375mm (14¾in)

2. The opening should be soundly constructed of brick, pre-

cast concrete or be a proprietary builders opening.

3. The base of the opening should be sound and non-

combustible and must be flat and level.

4. The base of the builders opening should be at the same

height as the finished level of the hearth.

IMPORTANT: If a false chimney breast is intended to

house the boiler, a simulated builders opening, within

the breast, must be provided.

5. The builders opening must not communicate with voids,

pipe ducts or spaces other than the room in which the

appliance is situated.

4.2 Location

1. The appliance must be installed in the living space of a

dwelling.

2. Restrictions to the siting of the appliance are covered by

BS 5546. The appliance may not be installed in bathrooms,

shower rooms, bedrooms or bed sitting rooms.

4.3 Fireplace Opening & Surround

1. If a fireplace surround is to be used, it must be centrally

placed and have opening sizes and a vertical flat area as

detailed in the Installation and Servicing Instructions for the

fire.

4.4 Frame Extension Kit

1. If the depth of the builders opening is less than the

375mm minimum specified, it can be increased by the use of

the Frame Extension Kit.

2. Kit N° 234887 is suitable for use with Inset 2 TS, BS and

FS models.

For Inset 2 KS, Kit N” 239341 must be used.

3. Full installation details are included in the kit.

4.0 Site Requirements - Page 10

4.5 Flue

1. The flue installation must conform to BS 5440 Pt 1. The

flue must have a minimum vertical height of 3m (10ft) and

have a minimum internal cross section area of 12,700 mm2

(20in2), this is satisfied by a flue of 125mm (5in) internal

diameter.

A suitable terminal is required for all installations.

2. 9in x 9in Brick

Flues previously used for other fuels must be thoroughly

swept. The flue must be lined with a 125mm (5in) flexible

liner. The bottom of the liner should terminate 500mm (20in)

above the base of the builders opening. The flue must be

sealed between the liner and the brickwork at both the top

and bottom.

An approved terminal must be installed.

3. Acid Resistant Liner

A flue constructed of acid resistant liners is satisfactory

provided the size requirements are met. The boiler flue outlet

can be connected to the flue by means of a short length of

125mm (5in) of flue pipe. A seal must be made in the

annular space between the outer face of this flue pipe and

the acid resistant liner.

An approved terminal must be installed.

4. Precast Flues

These must conform to BS 5440 Pt 1 and be correctly

installed without intrusion of cement into the flue passage.

An approved terminal must be installed.

5. Proprietary Flues

A flue of this type must meet the size requirements specified

and be installed in accordance with the flue manufacturers

recommendation and relevant codes of practice.

An approved terminal must be installed.
