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With the introduction of Self Certification Schemes, the Benchmark Logbook is being withdrawn.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.

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 !!

Working at Height

In order to reduce the number of fatalities and major accidents attributable to working at height, the Health and Safety Executive has introduced comprehensive regulations and guidance that should be followed by all businesses working at height.

The following paragraphs consider some of the main features of the regulations and guidance. This is, however, only a limited summary and it is recommended that all businesses planning on undertaking air source heat pump heating installations obtain a copy of the regulations and guidance issued by the Health and Safety Executive and carefully consider the contents.

The regulations and guidance state that you are required to carry out a risk assessment for all work conducted at height and to put in place arrangements for:

• Eliminating or minimising risks from work at height.

• Safe systems of work for organising and performing work at height.

• Safe systems for selecting suitable work equipment.

• Safe systems for protecting people from the consequences of work at height.

The regulations and guidance highlight a hierarchy for safe work at height:

• Avoid the risk by not working at height if practicable.

• Prevent falls. Where it is not reasonably practicable to avoid work at height, you are required to take suitable and sufficient steps to prevent the risk of a fall including selecting the most suitable work equipment (in accordance with the regulations).

• Mitigate the consequences of a fall; where the risk of a person or object falling still remains, take suitable and sufficient measures to minimise the distance and consequences of any fall.

Collective protection measures, such as guard rails on scaffold, should be given priority over personal protection measures, such as safety harnesses.

Within the regulations’ framework, you are required to:

1) Assess the risk to help you decide how to work safely.

2) Follow the hierarchy for safe work at height (i.e. avoid, prevent and mitigate).

3) Plan and organise your work properly, taking account of weather conditions and the possibility of emergencies.

4) Make sure those working at height are competent.

5) Make use of appropriate work equipment.

6) Manage the risks from working on or around fragile surfaces and from falling objects.

7) Inspect and maintain the work equipment to be used and inspect the place where the work will be carried out for both access and egress.

2. The following conditions should be observed at all

times:

The static head must not exceed 30m of water. The static head must not be less than 1m 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. There is a drain cock supplied in the plumbing kit.

4.2 Treatment of Water Circulating

Systems

All recirculatory water systems will be subject to corrosion unless they are flushed and an appropriate water treatment is applied. To prevent this, follow the guidelines given in BS 7593 “Treatment of Water in Domestic Hot Water Central Heating Systems” and the treatment manufacturers instructions.

Treatment must involve the use of a proprietary cleanser, such as Sentinel X300 or X400, or Fernox F3 and an inhibitor such as Sentinel X100 or Fernox MB-1.

Full instructions are supplied with the products, for further information contact Sentinel (0800 389 4670) or Fernox (0870 870 0362).

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 inhibitor manufacturer’s instructions. (Test kits are available from inhibitor stockists.)

For information or advice regarding any of the above contact Technical Enquiries 0844 871 1555.

4.3 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 a drop in temperature across the system of between 11& 20°C.

3. 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 (Fig. 4).

4.4 System Controls

1. 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.

4.5 Fully Pumped Open Vent System (Fig. 5)

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 feed and expansion tank.

3. The flow pipe from the boiler form part of the vent pipe. No part of the open vent may contain a valve.

4. Inverted pipe runs must be avoided.

5. On low capacity systems with a maximum available flow rate of less than 8.3l/min (temperature differential ›25°C) an external bypass must be fitted .

6. The bypass must be of the automatic pressure operated type.

4. Expansion Vessel. A diaphragm type expansion vessel to BS 4814:1 shall be fitted close to the inlet side of the pump. The connecting pipework should not be less than 15mm. Pipework connecting the expansion vessel should not incorporate valves of any sort.

Methods of supporting the vessel are supplied by the vessel manufacturer.

The nitrogen or air charge pressure of the expansion vessel shall not be less than the hydrostatic head, (height of the top point of the system above the expansion vessel). To size the expansion vessel it is first necessary to calculate the volume of water in the system in litres. The following volumes may be used as a conservative guide to calculating the system volume.

Boiler Heat Exchanger: 1.55 litres Small Bore Pipework: 1 litre per kW of system output Micro Bore Pipework: 7 litre Steel Panel Radiators: 8 litre per kW of system output Low Water Capacity Radiators: 1 litre per kW of system output Hot Water Cylinder: 1 litre per kW of system output

If the system is extended, the expansion vessel volume may have to be increased unless provision has been made for extension. Where a vessel of the calculated size is not available, the next available larger size should be used.

The boiler flow temperature is controlled at approx. 75°C.

The vessel size can now be determined from the information in table 1 where V = System volume in litres.

5. Cylinder. The hot water cylinder must be an indirect coiler type.

6. Method of Make Up. Provision shall be made for replacing water loss from the system either:-

a) From a make up vessel or tank mounted in a position higher than the top point of the system and connected through a non-return valve to the system on the return side of the hot water cylinder or the return side of all heat emitters. or b) Where access to a make up vessel would be difficult by using the mains top up method or a remote automatic pressurisation and make up unit.

7. Mains Connection. There shall be no connection to the mains water supply or to the water storage tank which supplies domestic hot water even through a non-return valve, without the approval of the Local Water Authority.

8. Filling Point. A filling point connection on the central heating return pipework must be provided to facilitate initial filling and pressurising and also any subsequent water loss replacement/refilling.

The sealed primary circuits may be filled or replenished by means of a temporary connection between the circuit and a supply pipe, provided a ‘Listed’ double check valve or some other no less effective backflow prevention device is permanently connected at the inlet to the circuit and the temporary connection is removed after use.

The filling method adopted must be in accordance with all relevant water supply regulations and use approved equipment.

The boiler MUST NOT be connected to the same supply as the firefront as their fuse ratings are different and subsequent damage may occur.

2. The boiler supply cable within the builders opening should be 0.75mm

to IEC 53 code 227 (heat resistant).

3. It is preferable to route the electrical supply cable to the right hand side of the builders opening. If however it must come from the left hand side it must be routed so as not to restrict the servicing of the appliance.

4. The cable must be routed to avoid contact with any part of the boiler.

5.9 Condensate Drain - General

Failure to install the condensate discharge pipework correctly will affect the reliable operation of the boiler.

1. Ensure the discharge of condensate complies with any national or local regulations in force.

BS 6798 & Part H1 of the Building Regulations give further guidance.

2. If any further drain pipe is required (additional to that supplied with the boiler), it should be run in a proprietary material e.g. PVC, PVC-U, ABS, PVC-C or PP. John Guest ‘Speedfit’ components are recommended.

3. Metal pipework is NOT suitable for use in condensate discharge systems.

4. Any pipe fitted externally must be kept as short as possible to minimise the potential of freezing and must be insulated using waterproof material.

5. When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered.

5.10 Condensate Disposal (Fig. 12)

1. This boiler incorporates an automatic pumped condensate system. The pump is submerged in a sump assembly and is activated by the discharge float switch. A second (safety) float switch is fitted.

2. The pump has an effective head of 3.5 metres. The condensate outlet is positioned at the top right front of the boiler. It is 10mm diameter plastic.

3. 3.5 metres of flexible 10mm condensate discharge pipe and a 10mm push fit elbow are supplied with the boiler.

4. The 10mm pipe can be routed to a maximum of 3.5 metres vertically and then discharge via gravity or be routed horizontally. A combination of vertical and horizontal runs is permissible.

5. The pipe must be adequately supported, either using suitably spaced clips or run within larger diameter pipe. When using clips take care not to deform the pipe.

6. When routing the pipe through a wall it must be suitably sleeved. Also the pipe must not be exposed to sources of heat, and should be protected in locations where it may be damaged.

7. The pipe should be routed so that any sharp bends, dips and loops are avoided. A minimum radius of 100mm is recommended for any bends. No slope is necessary and air breaks are not required on the pumped part of the condensate run.

8. Any part of the condensate drain system that is outside the dwelling, or in an unheated part of it must be at least 21.5mm diameter.

5.10 Condensate Disposal (cont.)

9. Ensure that the condensate can discharge freely (without blockage or restriction of the pipe) into the drain.

10. Examples are shown of condensate pipe methods of termination:-

i) via an internal discharge branch

(e.g. sink waste) - Fig. 13.

ii) to an internal or external soil and vent pipe -

Fig. 14.

iii) to a drain or gully - Fig. 15. Ensure that the

condensate can discharge freely (without blockage or restriction of the pipe) into the drain.

iv) to a soakaway - Fig. 16.

5.11 Condensate Pump Operation

1. The pump operates for 2 seconds when mains voltage is applied to the boiler, e.g. when the power has been interrupted and then reinstated.

2. If the boiler reset rocker switch has been operated the pump will run also for 2 seconds.

3. When the level of condensate in the sump is sufficient to activate the discharge float switch the pump will run for 7 seconds, during which time about 0.6 litres of condensate will be discharged.

4. In the event of condensate not being discharged the safety float switch will operate when the volume of condensate in the sump reaches 1.05 litres. Once the safety float switch has been activated the boiler will lockout.

5. The total volume of the sump is 1.5 litres.

7.0 Installation

INSTALLATION SEQUENCE There are 4 main elements to the installation of the Baxi Bermuda BBU 15 HE:-

• Preparation of pipework & opening

• Inserting the flue into the chimney

• Siting & fixing the boiler

• Fitting the terminal assembly The sequence in which these are performed may depend upon various factors beyond the scope of these instructions. The above list is intended as a guide based on a typical installation. It is not necessary to open the firefront pack until the boiler and flue are installed, and the boiler is ready to be commissioned. The firefront pack includes full instructions.

7.1 Initial Preparation

1. Remove the outer carton from the boiler pack. Discard the packing pieces and remove the fitting kit.

2. Ensure that the base of the builders opening is clean and level.

3. Complete any pipework installation and routing of electrical cables within the builders opening that may be difficult once the boiler is in place.

7.2 Flue System

1. The actual length of flue (as opposed to the vertical distance from the boiler top to the chimney outlet) MUST be established before commencing.

2. The flue must have a minimum vertical height of 3m and have no bends greater than 45°. NO HORIZONTAL RUNSARE PERMITTED !

3. Depending on the actual flue length it may be beneficial to shorten the flue at this point to enable easier handling.

4. Take one of the 60mm lip seals supplied and fit to the first groove in the flue duct. Also fit the 100mm lip seal to the air duct. (Figs. 17 & 18).

NOTE: Talcum powder may be used to ease fitting of the adaptors over the seals. DO NOT use oil, grease or soap.

5. Unfasten the clips on the boiler adaptor and insert the end of the flue duct with the seal into the 60mm socket. Ensure the seal is positioned past the clips, then engage the clips over the larger diameter ‘rib’ on the duct (Fig. 19).

6. Repeat the process for the 100mm air duct (Fig. 20)

7.0 Installation

7.2 Flue System (cont.)

8. It is recommended that the Pull Cone Flue Adaptor (part no. 720111801) is used as shown to ease the fitting of the flue into the chimney and prevent damage to the adaptor.

9. The cone has two internal lugs that engage on the boiler adaptor in a bayonet action (Figs. 21 & 22).

10. A suitable weight should then be tied to the guide rope fixed to the cone. The weight can then be passed into the chimney and will draw the guide rope down (Fig. 23).

11. Once the Pull Cone is visible in the builders opening it can be removed. It can be re-used indefinitely on other installations.

Note: It is recommended that the boiler is installed at this point. See Sections 8.3 to 8.7

12. Remove the plastic plug from the boiler flue outlet. Grasp the adaptor and locate it into the boiler, ensuring the two large barbs lock into position under the boiler top panel (Fig. 24) Fit the ‘C’ clip to the adaptor to secure the flue. It must fit into the barbs and clip securely into place (Fig. 24a).

13. There will now be an excess of flue and air duct protruding from the chimney.

14. Cut the excess concentric ducts to leave approximately 300 to 500mm protrudung from the chimney and pass the square closure plate over the air duct (Figs. 25 & 26).

15. Cut the 100mm air duct ONLY that 5 ‘ribs’ are above the level of the chimney, taking care not to damage the 60mm flue duct.

16. In a similar way to fitting the boiler adaptor fit the air duct clamp to the air duct. This will prevent the duct falling back into the chimney (Fig. 27).

7.2 Flue System (cont.)

16. Pass the air duct collar and air cowl over the 60mm flue duct (Fig. 28) and secure the collar to the closure plate with the screws supplied (Fig. 29). The air cowl will fit snugly over the collar.

17. Cut the protruding 60mm flue duct down so that 5 ribs are visible and fit the remaining 60mm lip seal into the first groove (Fig. 30). The flue duct adaptor can now be fitted in the same manner as the boiler adaptor (Fig. 31).

18. Fit the terminal cap over the flue duct adaptor and air cowl. Once the cap is clipped into position it cannot be removed easily without damage (Fig. 33).

19. Cement over the closure plate and air duct collar to a depth of approximately 100mm. Consideration should be given to the potential accumulation of snow in this area, and the possibility of it blocking the air inlet (Fig. 34).

IMPORTANT: The CO

must be only be checked and adjusted to set the valve if a suitable calibrated combustion analyser is available, operated by a competent person - see Section 9.1

1. The combustion (CO

) may be checked after running the boiler for several minutes. To do this it is necessary to set the boiler to ‘Calibration Mode’.

2. Ensure that all external controls are calling for heat. The actual current boiler temperature is shown on the display.

3. Turn both control knobs fully anticlockwise, then quickly turn the right hand knob

/4clockwise twice and back fully

anticlockwise (Fig. 56).

4. The display will now alternate between ‘SF’ and the current boiler temperature and both green LEDs will flash (Figs. 57 & 58).

5. Turn the left hand knob fully clockwise. As the knob is turned the display will change, indicating the fan speed.

6. The display will show ‘00’, indicating maximum rate, then revert to ‘P ‘ alternating with the current boiler temperature (Figs. 59, 60 & 61 ).

7. Remove the plug from the flue sampling test point. Insert the analyser probe and allow sufficient time for the reading to settle (Fig. 56).

The CO

should be 9.3% ± 0.2

8. It is possible to alter the CO

by adjustment of the gas valve. Remove the plastic cover from the ‘Max Rate’ adjustment screw. At maximum rate the ‘Max. Rate’ adjustment screw should be turned, using a suitable hexagon key, until the correct reading is obtained (Fig. 62). Turning clockwise will reduce the CO

. Anticlockwise will

increase the CO

9. The CO

must then be checked at minimum rate. Turn the left hand knob fully anti-clockwise. As the knob is turned the display will change, indicating the fan speed. When the display reads ‘ 0’ the boiler runs at minimum rate.

The CO

should be 8.2% ± 0.2

10. With the boiler on minimum, the ‘Min. Rate’ adjustment screw must be altered, using a suitable hexagon key, after removing the cap (Fig. 62). Turning anti-clockwise will reduce the CO

. Clockwise will increase the CO2.

11. The ‘Calibration Function’ is maintained for 20 minutes unless the maximum CH temperature is exceeded. The function can be disabled at any time by turning the right hand knob.

12. Check the CO/CO

ratio. This must be less than 0.004.

12.0 Fault Finding

NOTE: When instructed to

operate the reset button, press and hold for 5 seconds to reset the boiler.

12.1 Initial Fault Finding Checks

1. Check that gas, water and electrical supplies are available at the boiler.

2. Electrical supply = 230V ~ 50 Hz. Check the CH & DHW system. The preferred minimum gas pressure is 20 mbar.

3. Carry out electrical system checks, i.e. Earth Continuity, Resistance to Earth, Short Circuit and Polarity with a suitable meter.

NOTE: These checks must be repeated after any servicing or fault finding.

4. Ensure all external controls are calling for heat and check all external and internal fuses. Before any servicing or replacement of parts, ensure the gas and electrical supplies are isolated.

12.2 Error Codes

1. If a fault occurs on the boiler an error code may be shown on the boiler display and the Boiler Control.

2. The codes are either two or three digit, preceded by the letter 'E'. For example, code E133 will be displayed by 'E1' alternating with '33'. E20 is shown as 'E' then '20'

E20 & E28 indicate faulty or incorrect components.

E110 shows overheat of the primary water or excess condensate in the sump.

E125 is displayed if within 2 hours of the burner lighting the boiler temperature twice exceeds the selected temperature by 25°. In these instances poor primary circulation or no water in the system is indicated.

E133 indicates that the gas supply has been interrupted, ignition has failed or the flame has not been detected.

E155 indicates a Boiler Control reset when Service & Boiler Control reset counters are out of step. Boiler Control default not restored correctly.

E158 indicates a condensate discharge system fault.

3. By pressing the 'Reset' button on the Boiler Control for a minimum of 5 seconds when E110 & E133 are displayed it is possible to relight the boiler.

4. If this does not have any effect, or the codes are displayed regularly further investigation is required. It is possible to reset the boiler up to 4 times in any 5 hour period. Further resets via the Boiler Control are then blocked for 5 hours unless a Service Reset is performed.

Table Of Error Codes

To perform a Service Reset it is necessary to have access to the boiler. By pressing the Reset rocker switch on the right of the boiler case for a minimum of 5 seconds when error codes are displayed it is possible to reset the boiler once the fault has been rectified.

Service Reset

Following a Service Reset it is necessary to restore the Boiler Control to default condition:-

Disconnect the main power supply On reinstating the power supply the Boiler Control display will count down from 7. Before the count reaches 3 press both the ‘On/Off’ and ‘Reset’ buttons simultaneously and hold until the count reaches 0. The Boiler Control display will show ‘SEt’ to confirm default restoration.
