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.
ISO 9001
FM 00866
0086
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.
You have just purchased one of our appliances and we thank you for the trust you have placed in our products. Please note that
the product will provide good service for a longer period of time if it is regularly checked and maintained. Our customer support
network is at your disposal at all times.

2.2 Recommendations
WARNING
Installation, repair and maintenance must be carried
out by a Gas Safe Registered Engineer
(in accordance with prevailing local and national
regulations).
When working on the boiler, always disconnect the
boiler from the mains and close the main gas inlet
valve.
After maintenance or repair work, check the

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.
• 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
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 !

4.1 General Description
1. The Baxi EcoBlue Advance Combi boilers are fully automatic
gas fired wall mounted condensing combination boilers. They
are room sealed and fan assisted, and will serve central heating
and mains fed domestic hot water.
NOTE: The EcoBlue Advance 28 & 33 Combi ERP models differ
in several repects - these are detail in Section 14.
2. The boiler is set to give a maximum output of :-
24 model - 24 kW DHW
21.2 kW CH (Condensing)
28 model - 28 kW DHW
25.3 kW CH (Condensing)
33 model - 33 kW DHW
29.6 kW CH (Condensing)
40 model - 40 kW DHW
33.8 kW CH (Condensing)
Boiler Control
Flap
Fig. 1
3. The boiler is factory set for use on Natural Gas (G20).
4. The boiler is suitable for use only on fully pumped sealed
heating systems. Priority is given to domestic hot water.
5. The boiler data badge gives details of the model, serial
number and Gas Council number and is situated on the boiler
lower panel. It is visible when the control box is lowered (Fig. 2).
6. The boiler model, serial number and Gas Council number are
also shown on the information label behind the boiler control flap
(Fig. 1). This is for user reference.
7. The boiler is intended to be installed in residential/domestic
environments on a governed meter supply only.
8. The boiler must be installed with one of the purpose designed
flues such as one of the standard horizontal telescopic flue kits
detailed in the Flue Installation 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 Installation Guide supplied in
the Literature Pack.

4.2 Operating Principle
The boiler can be set in 3 operating modes:- ‘Summer’
(DHW only), ‘Winter’ (CH & DHW) or ‘Heating Only’ (CH only) by
use of the button.
4.2.1 Central Heating Mode
1. With a demand for heating, the pump circulates water through
the primary circuit.
2. Once the burner ignites the fan speed 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).

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 Sensor (Hall Effect
Sensor) 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.
4.2.3 Boiler Frost Protection Mode
1. The frost protection mode is integral to the appliance and
functions as long as there is power to the boiler, as indicated by
the standby signal .
2. With CH & DHW or CH only selected, when the boiler
temperature falls below 5°C the boiler will fire until a
temperature of 30°C is reached.
3. If DHW only is selected, when the boiler CH temperature falls
below 5°C the boiler will fire until a temperature of 30°C is
reached. When the boiler DHW temperature falls below 5°C the
boiler will fire until a temperature of 7°C is reached.
4. Further protection can be incorporated by using a system
frost thermostat.
4.2.4 Pump Protection
1. This activates once a week if there has been no demand. The
pump runs for 30 seconds to prevent sticking.
