General requirements 3 1435 10 550 3.4 Gas supply The gas supplier should ensure the availability of an adequate supply of gas. A gas meter may only be connected to the service pipe by the supplier of gas or their contractor. An existing meter should be checked to ensure that it is capable of passing the rate of gas supply required. Installation pipes should be fitted in accordance with BS 6891. In IE the current edition of IS 813. Pipe work from the meter to the boiler must be of an adequate size.
3 General requirements 3.5.1 Flue termination The following details refer to both flue systems. a. The terminal must be located where the combustible substances can escape freely at all times. b. A plume of water vapour will sometimes be visible from the flue terminal. Positions where this could be a nuisance should be avoided. c.
General requirements 3 3.8 Domestic hot water cylinder Caution! Single feed indirect cylinders are not suitable. The domestic hot water cylinder must be of the double feed fully indirect coil type. It must be suitable for working at a gauge pressure of 0.35 bar above the safety valve setting. Unvented hot water cylinder 3.8.1 The ecoTEC plus can be connected to an unvented hot water cylinder.

To prepare the boiler for initial lighting first ensure that all external controls are not calling for heat. For access open the front flap by pulling at the centre of the case strip. Turn on the appliance at control (1), see fig 5.4.
6 Natural gas to LPG conversion 6 Natural gas to LPG conversion The ecoTEC plus is able to be field adjusted for use on LPG – propane G31 gas. To enable conversion the use of a combustion analyser is necessary. Caution! After converting from natural gas to LPG, commission and check boiler function as described in commissioning section of the servicing and installation instructions. NAT.
7 Functional checks commissioning (part II) Commissioning and Service log. 7 Functional checks commissioning (part II) Functional checks Procedure: After installing and checking the gas supply pressure, perform a function check before commissioning the appliance and handing over to the user. • Commission the appliance according to the relevant operating manual. • Check the gas supply pipe, flue system, heating system and the hot water pipes for leaks.
7 Functional checks commissioning (part II) 7.1.3 Final flush of the heating system (hot) • Operate the appliance until the heating system is up to temperature. • Check the heating system for leaks. • Connect a hose to the drain valve located at the lowest position of the heating system. • Shut off the appliance, open the drain valve and all bleed valves on the radiators and allow the water to flow out of the heating system and the boiler quickly and fully. • Close the drain valve.
Inspection and maintenance 8 8 Inspection and maintenance 8.1 Initial inspection To ensure the continued safe and efficient operation of the boiler it is recommended that it is checked and serviced as necessary at regular intervals. The frequency of servicing will depend upon the particular installation conditions and usage, but in general once per year should be adequate. Danger! It is law that all servicing work is carried out by a competent person (CORGI registered).
8 Inspection and maintenance Overview of the inspection and maintenance tasks No. Activity Column 1 Inspection must be carried out once a year 1 Check the air/ gas flue system and ensure it is not blocked, damaged and is fitted correctly. x 2 Measure the gas rate during operation (see table 5.1. inside section 5 commissioning part I). If the gas rate is lower than the minimum gas rate, follow the maintenance schedule in column 2.
Inspection and maintenance 8 8.1.4 General All routine servicing requirements can be achieved by the removal of the front casing, inner case and chassis panel only. Remove the two screws on the underside of the front casing and lift off. Remove the two screws on the front of inner case and lift off, see fig 8.1. Drop down the electronics box into the service position. Remove the four screws from the chassis panel, see fig 8.2. Remove the chassis panel by pulling it out at the top from its retaining slots.
8 Inspection and maintenance 8.1.5 Spark electrode Disconnect the ignition lead and earth lead from the igniter unit and two securing screws at the spark electrode. Withdraw the spark electrode carefully from the combustion chamber, see fig 8.4. Inspect the tips for damage. Clean away any debris and check the spark gap is 3.5 -4.5 mm. Check the electrode gasket for signs of damage and replace if necessary. 8.1.
8 Inspection and maintenance Note! If the burner has to be removed it will require a new gasket when refitted. SECTION THROUGH BURNER DOOR SHOWING POSITION OF SEAL Note! When replacing ensure that the sealing grommet, situated below the gas valve is correctly re-seated. BURNER DOOR SEAL 8.1.7 Combustion chamber and heat exchanger Refer to fig 8.8. Remove loose debris from combustion chamber using a soft brush and vacuum cleaner.
8 Inspection and maintenance 8.1.8 Condensate drain The condense drain does not normally need removing during servicing. To flush the condense drain carefully pour water into the heat exchanger and check that water flows freely to drain. If the condense drain is blocked, refer to parts replacement section 11 for removal. 8.1.9 Inner casing panel seal check Refer to fig 8.9. Check the condition of the seal, replace as required. To replace remove the old seal, thoroughly clean the casing surfaces.
Combustion analysis 9 9 Combustion analysis Note! The boiler is fitted with a combustion analysis test point. A suitable combustion analyser can be connected to this point to establish the combustion performance of the boiler. 9.1 Check CO2 content Refer to table 9.1 and if necessary set (air-ratio adjustment). Note! Combustion analysis must be carried out at annual service if a flue gas analyser is available, if no analyser is available then visual checks should be carried out as per service schedule.
