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. From 1 April 2005 this can be achieved via a

Competent Persons Self Certification Scheme as an option to notifying

the Local Authority directly. Similar arrangements will follow for Scotland

and will apply in Northern Ireland from 1 January 2006.

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

certification scheme for gas heating appliances.

These arrangements represent a change from the situation whereby

compliance with Building Regulations was accepted as being

demonstrated by completion of the Benchmark Logbook (which was

then left on site with the customer).

With the introduction of Self Certification Schemes, the Benchmark

Logbook is being withdrawn. However, a similar document in the form

of a commissioning checklist and service interval record is incorporated

at the back of these instructions.

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.

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.

Safe Manual 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.

There is no ‘safe’ limit for one man - each person has different capabilities. The boiler should be handled and lifted by TWO PEOPLE.

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 asses 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 !!

3.0 Appliance Operation

8© Baxi Heating UK Ltd 2009

NOTE: All delay timers mentioned in 3.1 and 3.2 are

overridden by domestic hot water demand.

3.1 Central Heating Mode (Fig. 2)

1. With a demand for heating, the pump circulates water

through the primary circuit. At a pre-determined flow

rate the central heating flow switch operates, initiating

the ignition sequence.

2. The main burner ignites at low rate, then the gas valve

controls the gas rate to maintain the heating

temperature measured by the temperature sensor.

3. When the flow temperature exceeds the setting

temperature, a 3 minute delay occurs before the burner

relights automatically (anti-cycling). The pump continues

to run during this period.

4. When the demand is satisfied the burner is

extinguished and the pump continues to run for a

period of 3 minutes (Pump Overrun).

3.2 Domestic Hot Water Mode (Fig. 3)

1. Priority is given to the domestic hot water supply. A

demand at a tap or shower will override any central

heating requirement.

2. The flow of water will operate the DHW flow switch

which requests the 3 way valve to change position. This

will allow the pump to circulate the primary water

through the DHW plate heat exchanger.

3. The burner will light automatically and the

temperature of the domestic hot water is controlled by

the temperature sensor.

4. When the domestic hot water demand ceases the

burner will extinguish and the diverter valve will remain

in the domestic hot water mode, unless there is a

demand for central heating.

IMPORTANT: When the selector switch is in the

‘0’ (Off) position the electrical supply to the boiler

is isolated. The boiler will not operate and the

integral timer (if fitted) will require resetting once

the selector switch is set to either Position (i) or

Position (ii).

3.3 Frost Protection Mode

1. The frost protection mode is integral to the appliance

and functions only with the selector switch (see Section

2.1) in the domestic hot water and central heating

position. If the system temperature falls below 5° C then

the boiler will fire on its minimum setting until a flow

temperature of 30° C is reached. Further protection can

be incorporated by using a system frost thermostat.

3.4 Pump Protection

1. With the selector switch (see Section 2.1) in either

the central heating or central heating and domestic hot

water position the pump will automatically operate for 1

minute in every 24 hours to prevent sticking.
