With regards to the Manual Handling Operations, 1992 Regulations, the following lift operation exceeds the recommended weight for a one man lift. General recommendations when handling Clear the route before attempting the lift. Ensure safe lifting techniques are used – keep back straight – bend using legs. Keep load as close to body as possible. Do not twist – reposition feet instead.
Boiler installation sequence 4 Positioning of Appliance for Final Installation – in roof space restricting installation. This appliance is deemed to be a one person lift when removed from the carton. Obtain firm grip on front and sides of appliance, lift upwards, ensure stable balance achieved and lift upwards to drop into place onto bracket. If 2 persons positioning onto bracket obtain firm grip at front and sides/base of boiler.
4 Boiler installation sequence 4.2.2 Unpack the boiler To unpack the boiler, cut both plastic carton straps, open box and lift out the polystyrene top packing. Lift the cardboard box upwards. Note Care should be taken not to scratch the white surface of the boiler casing. • Fix the paper template to the wall ensure that the template is vertical. The template shows: – The position of the fixing holes for the boiler mounting bracket. – The position of the connections. – The position of the flue exit hole.
Boiler installation sequence 4 4.5 Installing the flue system • Install the flue system (refer to the seperate air/flue duct installation instructions). 4.6 Fitting the boiler • Lift the boiler (3) up to the wall so that it is slightly above the hanging bracket (1). Note Lift the boiler from either side at the bottom edge • Lower the boiler slowly onto the hanging bracket so that the cross member at the rear of the boiler fully engages onto the hanging bracket. 4.

Boiler installation sequence 4 Note Flush all foreign matter from the mains supply before connecting to the boiler. • Insert the seal (1) and connect the service valve (2) to the appliance cold water connection. • Fit the union nut (4) and the compression olive (3) to the pre-formed tail provided with ecoTEC plus appliances (5). The diameter of the pipe is 15 mm. • Fully insert the pre-formed tail into the service valve. Tighten the union nuts.
4 Boiler installation sequence 4.12 Heating connection ecoTEC pro combination boiler Caution! When making final connection to the boiler, if using soldered fittings, extra care should be taken to avoid damage to isolation valves through heat transfer. 4.12.1 bar Heating flow and return connection Note Before connecting the heating circuit to the boiler, all pipework and radiators must be thoroughly flushed to remove any installation debris. 2 4 1 3 5 ecoTEC plus combination boiler 13 Fig. 4.
Boiler installation sequence 4 Caution! To ensure fumes do not escape through the syphon of the boiler the trap must be filled with water before the boiler is turned on. Therefore the discharge pipework should be installed so as not to interfere with the removal and refitting of the condensate trap, we recommend the outlet pressure release valve pipe supplied is not shortened. You must leave a bottom clearance of at least 180 mm below the condensate trap for removal and refitting. 4.14.

Boiler installation sequence 4 4.16 Thermostatic radiator valves The boiler has a built in automatic by-pass valve making it ideal for use in systems with thermostatic radiator valves (no separate system by-pass is required). For optimum fuel economy where TRV’s are used they must be used in conjunction with a boiler control interlock. A programmable room thermostat or separate timer and room thermostat will ensure complete boiler shut down when the heating demand is satisfied.
5 Commissioning Part I 5 Commissioning Part I 5.1 Preliminary electrical checks Check the electrical installation by carrying out short circuit, earth continuity and resistance to earth tests and a check for correct polarity. 5.2 Gas supply The complete gas installation including the gas meter must be inspected, checked for leaks and purged in accordance with BS 6891. In IE the current edition of IS 813. The gas supply to the boiler can be purged by slackening the gas service valve beneath the boiler.
Commissioning Part I 5 The ecoTEC plus combination boiler will be delivered with a filling loop. • Insert the double check valve (1) of the filling pipe at the cold water shutoff valve and secure the double check valve with the spring clip (2). • To fill, first open the stop valve (3). • Open the stop valve (4), so that water flows into the heating system. Fill the heating system as described in Section 5.4.4.
5 Commissioning Part I 5.6 Filling the condensate siphon 1 Fig. 5.5 Adjusting the by-pass valve (in combination boilers) 1 1 Fig. 5.4 Filling the condensate siphon Danger! Note that if the boiler is run with an empty condensate trap there is a danger that fumes might escape into the room and cause poisoning. For this reason, it is important to ensure that the trap is topped up each time the unit is cleaned.
Commissioning Part I 5 If the boiler version corresponds to the local gas family: • Proceed as described below. 1 If the boiler version does not correspond to the local gas family: • Perform the gas conversion in accordance with the gas conversion kit 0020010641. • Adjust the gas setting as described below (see sections 5.9.1 to 5.9.3). The combustion of this boiler has been checked, adjusted and preset at the factory for operation on the type of gas defined on the identification plate.

Functional checks (commissioning part II) 6 6 6.1 Functional checks (commissioning part II) plus pro Functional checks 6.1.1 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, exhaust system, heating system and the hot water lines (combination boilers only) for leaks.
6 Functional checks (commissioning part II) • Release water from the system until the system design pressure of 1.0 bar is attained. (The actual reading on the digital pressure gauge should ideally be 0.5 bar plus an additional pressure corresponding to the highest point of the system above the base of the boiler – 10 m head equals an additional 1 bar reading on the pressure gauge. The minimum pressure should not be less than 1 bar in any installation.
Inspection and maintenance 7 7 Inspection and maintenance 7.1 Inspection and maintenance intervals Danger! Risk of injury and risk of damage to property due to neglected inspection and maintenance! Neglected inspection and maintenance works or not observing the stated inspection and maintenance intervals can interfere with the operational safety of the boiler and can result in damage to property and to persons.
7 Inspection and maintenance - Correctness of electrical, water and gas connections. - Correctness of the water pressure. - The condition of the whole system, in particular the condition of radiator valves, evidence of leakage from the heating system and dripping taps. • Correct any faults before proceeding. • Check the boiler for gas and water leaks. • If necessary, refill and re-bleed the heating installation. • Replace the front casing to the boiler.
Inspection and maintenance 7 Note The boiler is fitted with a flue gas analysis point (4). A suitable flue gas analyser can be connected to this point to establish the combustion performance of the boiler. • Remove the front casing. • Start the testing program P.1. • Wait at least 5 minutes until the boiler reaches its operating temperature. • Measure the CO2 concentration at the flue gas analysis point (4). Compare the measured value with the corresponding value in Table 7.1.
7 Inspection and maintenance 7.1.5 Inspection and maintenance work steps Column 2 Maintenance Column 1 must be carried Inspection must out at regular be carried out intervals – but each year no longer than 5 years No. Activity Check the air flue gas installation for leaks and for proper fixation and ensure it is not blocked or damaged and is fitted correctly, complying with the relevant installation instructions. 2 Carry out a general inspection of the boiler for dirt and dust and clean as necessary.
Inspection and maintenance 7 7.2 Servicing the burner module 7.2.1 Removing the burner module The burner module consists of the burner, fan, gas valve und the gas supply (mixer tube). These four components make up the complete assembly, the burner module. • Disconnect the gas supply (3) on the gas valve.
