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.

CORGI operates a Self Certification Scheme for gas heating appliances.

With the introduction of Self Certification Schemes, the Benchmark L

ogbook is being withdrawn.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 serv

icing 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.

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

2. Once the main burner ignites the fan speed controls the gas rate to maintain the heating temperature measured by the temperature sensors.

3. When the demand is satisfied the burner is extinguished and a 5 minute delay occurs before the burner will re-light (anticycling), the pump continues to run for a period of 2 minutes (Pump Overrun).

1. The appliance is suitable for fully pumped SEALED SYSTEMS ONLY.

Treatment of Water Circulating Systems

Failure to flush and add inhibitor to the system will invalidate the appliance warranty.

• Central heating water systems will be subject to corrosion unless an appropriate water treatment is applied. This means that the efficiency of the system will deteriorate as corrosion sludge accumulates within the system, risking damage to pump and valves, boiler noise and circulation problems.

• When fitting new systems flux will be evident within the system, which can lead to damage of system components.

• All systems must be thoroughly drained and flushed out. Using, for example Betz-Dearborn Sentinel X300 or X400 or Fernox Superfloc Universal Cleanser. They should be used following the flushing agent manufacturer’s instructions.

• System additives - corrosion inhibitors and flushing agents/descalers should comply to BS7593 requirements, e.g. Betz-Dearborn Sentinel X300 and Fernox-Copal which should be used following the inhibitor manufacturer’s instructions.

• It is important to check the inhibitor concentration after installation, system modification and at every service in ac

cor

dance with the manufacturer’s instructions. (Test kits are

available from inhibitor stockists.)

• F

or information or advice regarding any of the above contact

Technical Enquiries - Tel: 0844 3711121.

• If thermostatic radiator valves are fitted, a radiator must be fitted with two lock shield valves or the system must include a proprietary automatic bypass valve, to enable correct operation of the pump o

1. The gas installation should be in accordance with the relevant standards. In GB this is BS 6891. In IE this is the current edition of I.S. 813 “Domestic Gas Installations”.

2. The connection to the appliance is a 22mm copper tail located at the rear of the gas service cock (Fig. 13).

3. Ensure that the pipework from the meter to the appliance is of adequate size, and the demands of any other gas appliance in the property are taken into consideration. Do not use pipes of a smaller diameter than the boiler gas connection (22mm).

4. For boilers connected to use LPG (propane), the inlet pressure must be 37mbar.

NNOOTTEE::

The appliance is fitted with a trap the depth of which is >= 75mm, therefore no other traps are required in the condensate run.

The condensation discharge pipe must not rise at any point along its length. There MUST be a fall of AT LEAST 2.5° (50mm per metre) along the entire run.

1. The condensate outlet will accept 21.5mm (3/4in) plastic overflow pipe which should discharge internally into the household drainage system, downstream of all other traps. if this is not possible, discharge into an outside drain is ac

ceptable.

2. Ensure the discharge of condensate complies with any national or local regulations in force. BBSS 66779988::22000000 && PPaarrtt HHII ooff tthhee BBuuiillddiinngg RReegguullaattiioonnss ggiivvee ffuurrtthheerr gguuiiddaannccee..

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

4. The pipe should be a minimum of 21.5mm diameter and must be supported properly.

7. If the boiler is fitted in an unheated location the entire condensate discharge pipe should be treated as an external run.

8. In all cases discharge pipe must be installed to aid disposal of the condensate.

9. When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered. If soil pipes or waste pipes are subjected to internal pressure fluctuations when WC’s are flushed or sinks emptied then back-pressure may force water out of the boiler trap and cause appliance lockout.

1. This high efficiency boiler will discharge a plume of water vapour from the flue. This should be considered when siting the flue terminal.

2. The following guidelines indicate the general requirements for siting balanced flue terminals. For GB recommendations are given in BS 5440 Pt 1. For IE recommendations are given in the current edition of I.S. 813 “Domestic Gas Installations”.

3. If the terminal discharges onto a pathway or passageway, check that combustion products will not cause a nuisance and that the terminal will not obstruct the passageway.

4. If a terminal is less than 2 metres above a balcony,above ground or above a flat roof to which people have access, then a suitable terminal guard must be provided - Part No: 951507.

IIMMPPOORRTTAANNTT::

• Only

OONNEE

of the 25mm clearances (Positions ‘O’ to ‘S’ in

This kit is recommended if the condensate plume from the flue may cause a nui

sance or affect the surroundings. The air inlet remains outside and the flue duct is routed separately using a 60mm duct enclosed by a protective 80mm tube. To calculate the maximum lengths of 60/100 concentric flue and 60mm flue ducts, use the table below.

For installation details refer to the flue kit instructions. Dimensions from vertical terminals to opening windows should be in line with Fig. 19.

(For use with Standard horizontal telescopic flue kit - Part no. 956120 - only).

This kit is useful for deflecting the condensate plume away from walls or boundaries. It should only be used to deflect the condensate plume left or right.

Overheated appliance – Water temperature greater than 105°C. This causes a Non volatile lockout requiring a manual reset.

No Flame –No flame signal on ignition. The boiler makes up to 5 ignition attempts on loss of flame signal. Failure after 5 attempts causes a Non volatile lockout requiring a manual reset. No Flame –Loss of flame signal during normal operation Up to 5 loss of flame during normal operation is allowed before Non volatile lock out occurs requiring manual reset. The loss of flame count is reset when the boiler thermostat is satisfied

Temporarily overheated appliance – Water temperature is greater than 95°C This causes a volatile lockout that will automatically reset when the temperature drops below the boiler thermostat setting
