The Benchmark Scheme

Benchmark places responsibilities on both manufacturers and installers.

The purpose is to ensure that customers are provided with the correct

equipment for their needs, that it is installed, commissioned and

serviced in accordance with the manufacturer’s instructions by

competent persons and that it meets the requirements of the

appropriate Building Regulations. The Benchmark Checklist can be

used to demonstrate compliance with Building Regulations and should

be provided to the customer for future reference.

Installers are required to carry out installation, commissioning and

servicing work in accordance with the Benchmark Code of Practice

which is available from the Heating and Hotwater Industry Council who

manage and promote the Scheme. Visit www.centralheating.co.uk for

more information.

Building Regulations and the Benchmark Commissioning

Checklist

Building Regulations (England & Wales) require notification of the

installation of a heating appliance to the relevant Local Authority

Building Control Department. This can be achieved via a

Competent Persons Self Certification Scheme as an option to

notifying the Local Authority directly.

The Health & Safety Executive operates the ‘Gas Safe Register’, a self-

certification scheme for gas heating appliances.

This company is a member of the Benchmark initiative and fully

supports the aims of the programme. Its aim is to improve the

standards of installation and commissioning of central heating systems

in the UK and to encourage the regular servicing of all central heating

systems to ensure safety and efficiency.

Building Regulations require that installations should comply with

manufacturer's instructions. It is therefore important that the

commissioning checklist is completed by the installer. The relevant

section of Building Regulations only relates to dwellings. Therefore the

checklist only applies if the appliance is being installed in a dwelling or

some related structure.

The flowchart opposite gives guidance for installers on the process

necessary to ensure compliance with Building Regulations.

DANGER

If you smell gas:

1. Turn off the gas supply at the meter

2. Open windows and doors in the hazardous area

3. Do not operate light switches

4. Do not operate any electrical equipment

5. Do not use a telephone in the hazardous area

6. Extinguish any naked flame and do not smoke

2.3 Specific Safety Instructions

2.3.1 Handling

General

• The following advice should be adhered to, from when first

handling the boiler to the final stages of installation, and

also during maintenance.

• Most injuries as a result of inappropriate handling and lifting

are to the back, but all other parts of the body are

vulnerable, particularly shoulders, arms and hands. Health

& Safety is the responsibility of EVERYONE.

• Before lifting the boiler, the circumstances of the installation

must be assessed, please use appropriate manual handling

techniques and equipment.

• Do not handle or lift unless you feel physically able.

• Wear appropriate Personal Protection Equipment

e.g. protective gloves, safety footwear etc.

Preparation

• Co-ordinate movements - know where, and when, you are

both going.

• Minimise the number of times needed to move the boiler -

plan ahead.

• Always ensure when handling or lifting the route is clear

and unobstructed. If possible avoid steps, wet or slippery

surfaces, unlit areas etc. and take special care on

ladders/into lofts.

Technique

• When handling or lifting always use safe techniques - keep

your back straight, bend your knees. Don’t twist - move your

feet, avoid bending forwards and sideways and keep the

load as close to your body as possible.

• Where possible transport the boiler using a sack truck or

other suitable trolley.

• Always grip the boiler firmly, and before lifting feel where the

weight is concentrated to establish the centre of gravity,

repositioning yourself as necessary. See the ‘Installation’

section of these instructions for recommended lift points.

Remember

• The circumstances of each installation are different. Always

assess the risks associated with handling and lifting

according to the individual conditions.

• If at any time when installing the boiler you feel that you

may have injured yourself STOP !! DO NOT ‘work through’

the pain - you may cause further injury.

IF IN ANY DOUBT DO NOT HANDLE OR LIFT THE BOILER -

OBTAIN ADVICE OR ASSISTANCE BEFORE PROCEEDING !

3.2 Dimensions and Connections

IMPORTANT: The 1.5° fall provided by the elbow is

to allow condensate to run back to the boiler, for

disposal through the condensate discharge pipe.

When using extensions the fall along the flue

system must be increased to 3°.

Where extensions are used ensure the clearance

above the top of the flue elbow (X) is as shown in

the table below:-

4 Description of the Product

4.1 General Description

1. The Baxi EcoBlue Advance Heat Range are gas fired wall

mounted powered flue condensing boilers.

2. The maximum output of the boiler is :-

13 model - 13 kW

16 model - 16 kW

19 model - 19 kW

21 model - 21 kW

25 model - 25 kW

30 model - 30 kW

3. The boiler modulates automatically to the system load up to

the set output. It is designed for use on Natural Gas (G20) only.

4. The two illuminated User Interaction Controller push buttons

provide information about the operating condition of the boiler.

5. The boiler is suitable for fully pumped open vented central

heating and domestic hot water systems and sealed systems.

6. An information label giving details of the model, serial number

and Gas Council number is situated on the front left underside of

the outercase and is accessed by pulling forward gently (Fig. 1).

7. The boiler data label is positioned on the inside lower right-

hand side of the boiler and can be seen when the outercase

panel is removed (Fig. 1).

8. The boiler is intended to be installed in residential/domestic

environments on a governed meter supply only.

9. The boiler must be installed with one of the purpose designed

flues such as one of the standard telescopic flue kits detailed in

the Flue Accessories & Fitting Guide.

All systems must be thoroughly cleansed, flushed and

treated with inhibitor (see Section 5.2.6).

These Installation & Servicing Instructions MUST be

read in conjunction with the Flue Accessories & Fitting Guide

supplied in the Literature Pack.

4.2 Operating Principle

1. Switched Live On: When the boiler switched live turns on

the boiler, a 20 second check cycle takes place. If the flow

temperature is less than the boiler set-point temperature the

ignition cycle will start. Pre-purge, Ignition and Burner on.

2. Fan Pre-Purge: The boiler has a 10 second pre-purge (Fan

On, Spark Generator and Gas Valve off) before the start of the

ignition sequence.

3. Ignition: The boiler has a 5 second ignition period (Fan,

Spark Generator and Gas Valve on) and burner on occurs when

a flame is detected. If a flame is not detected within the 5

second ignition period then 4 more ignition attempts are made.

If a flame is not detected after the 5 ignition attempts the boiler

goes to an ignition lock-out and an error code is displayed.

4. Burner on: After a successful ignition, Burner on occurs (Fan

and Gas Valve on, Spark Generator off). The boiler flow

temperature is controlled by varying the fan speed (and thereby

the gas rate) to achieve the optimum boiler operation. If the

boiler flow temperature exceeds the boiler set-point, the burner

will turn off (Fan and Gas Valve off).

5. Overtemperature: If a boiler overtemperature event occurs

(triggering the safety thermostat) the burner shuts down (Fan off

and Gas Valve off). A locking signal is generated and an error

code is displayed.

6. Lockout: If a lock-out error is displayed (Fan, Spark

Generator and Gas Valve off) the boiler can only be reset by

manually pressing the reset button. If 5 lock-outs are reset

within a 1 hour period then boiler becomes inoperable. It is

necessary to switch off the power supply to the boiler, and when

reinstated the reset button pressed again to operate the

appliance.

Any lock-out errors that occur regularly will require further

investigation and rectification.
