COMMISSIONING REPORT

During the combustion process, hydrogen and oxygen combine to produce heat and water vapour. The water vapour produced is in the form of superheated steam in the heat exchanger. This superheated steam contains sensible heat (available heat) and latent heat (heat locked up in the flue gas). A conventional boiler cannot recover any of the latent heat and this energy is lost to the atmosphere through the flue.

The iQE condensing boiler contains an extra heat exchanger which is designed to recover the latent heat normally lost by a conventional boiler. It does this by cooling the flue gases to below 90° C, thus extracting more sensible heat and some of the latent heat. This is achieved by cooling the flue gases to their dew point (approximately 55° C).

To ensure maximum efficiency, the boiler return temperature should be 55° C or less, this will enable the latent heat to be condensed out of the flue gases. The boiler will achieve nett thermal efficiencies of

100%.

To achieve maximum performance from the iQE Internal boiler, it is recommended that the heating system is designed so that a temperature differential of 20° C between the flow and return is maintained. The use of modulating circulating pumps (now widely available) and effective control systems should be considered.

e iQE Internal boiler will however still operate

at extremely high efficiencies even when

it is not in condensing mode and therefore is suitable for fitting to an existing heating system without alteration to the radiator sizes. The boiler is capable of a maximum flow temperature of 75° C.

To achieve the maximum efficiencies possible from the iQE boiler, the heating system should be designed to the following parameters:

Radiators:-

Flow temperature 70° C Return temperature 50° C Differential 20° C

Underfloor:-

Flow temperature

50° C

Return

temperature

Differential

1 Size radiators with a mean water temperature of

60° C.

2 Design system controls with programmable room

thermos

tats or use weather compensating controls

to maintain return temperatures below 55° C.

The boil

er should not be allowed to operate with return temperatures of less than 40° C when the system is up to operating temperature.

3 The use of a pipe stat is recommended to control

the return temperature when using weather compensating controls.

Heating system design considerations

1.1

How a condensing boiler works

Page 5

2 - USER INSTRUCTIONS

The boiler is fully automatic once switched on, providing central heating (and

also heating your domestic hot water if you have a hot water cylinder fitted).

A 'mains on' neon, see Fig. A, lights when the boile

r is switched on, but does not necessarily

indicate the burner is firing. If your system includes a programmer, the boiler

wil

l provide hot water and central heating during

the periods set on the programmer.

To gain acces to the controls, pull the front panel forward at the top to disengage the fixing clips then lift it up and off the boiler. To replace locate the bottom of the panel over the fixing tags then push it towards the boiler to engage the fixing clips.

Fig. A Boiler controls

1 Ensure that - There is sufficient fuel, of the correct

type, in the supply tank and all fuel supply valves are open. The

water supply is on. The electricity supply to the boiler is off. The boiler On/Off switch is set to OFF. The room thermostat (if fitted) is at the desired setting. The boiler thermostat is set to the required setting (see Section 2.7).

2 Switch on the electricity supply to the boiler.

3 Set the On/Off switch to ON and, if fitted, the

pro

ammer (CH or HW) to ON.

The boi

ler will now light automatically.

4 If you have a programmer fitted in your system,

refer to the instructions supplied with the programmer and set the programmer. Set the H

W and CH functions to TIMED. The boiler will now operate during the 'on' periods set on the programmer.

For short periods - Set the On/Off to OFF. To restart, simply set the switch to ON.

For long periods: Set the On/Off switch to OFF and switch off the electricity supply to the boiler. If required, the fuel supply valve may be closed and the water and electricity supplies turned off at the mains.

To restart, refer to the full lighting instructions given in Section 2.3.

1 Check that the

boiler On/Off switch is ON.

2 Check that the programmer (if fitted) is working

and is in an 'on' period.

3 Check that all thermostats are set to the desired

setting and are calling for heat.

4 Check if the burner 'Lock-out' reset button

(on the burner) is lit. If it is, press it to start the burner. If the burner fails to light and goes to 'Lock-out' again, check that you have sufficient fuel in the storage tank and that the fuel supply valve is open. Check that the fire valve in the oil supply line has not tripped

5 Ensure that a fuse has not blown or that the

electricity supply has not failed.

6 Check to see if the safety thermostat has operated

(see Section 2.7).

If the burner still fails to light after carrying out these checks then a fault exists. Switch off the electricity supply to the boiler and contact your Service engineer.

iQE Horizon Internal oil boilers only operate on Class C2 Kerosene to BS 2869:1998.

You should always quote this type of fuel when ordering from your supplier.

Do not wait until the fuel runs out before you order some more. Sludge in the bottom of the tank may be drawn into the fuel lines. If it is possible, switch off the boiler when the new supply is delivered and leave the fuel to settle for an hour before restarting the boiler.

2 - USER INSTRUCTIONS

1 Boiler thermostat - This control allows the

temperature of the water leaving the boiler to heat the radiators and domestic hot water to be adjusted.

Note: If you have a cylinder thermostat on your hot water cylinder, this will control the temperature of your domestic hot water. The boiler thermostat setting must be equal to or above the cylinder thermostat setting to enable the cylinder thermostat to control the domestic hot water system.

2 Burner Lock-out reset button - If there is a

burner malfunction, a built-in safety circuit switches the burner off and the 'Lock-out' reset button (on the burner) will light. Usually such malfunctions are short lived and pressing the reset button will restore normal operation.

If the burner continually goes to 'Lock-out' a fault exists or the fuel supply is low. If you have sufficient fuel, you will need to call your Service engineer.

3 Safety thermostat - Your boiler is fitted with a safety heat thermostat which will automatically switch off the boiler in the case of a control malfunction

causing overheating.

If your boiler goes off and you try to light it but nothing happens and the 'Lock-out' reset button on the burner is not lit, the overheat thermostat has probably operated. The boiler will not light until the thermostat is reset. To reset, unscrew the small plastic cap (see Fig.A), press the button then replace the cap. If this condition continually repeats, contact your Service engineer.

4 Programmer (if fitted) - Refer to the instructions

suppplied with the Programmer.

5 Ventilation - Always ensure that the boiler has

adequate ventilation. Any ventilation openings provided by the Installer must not be obstructed. Periodically check that they are clear.

Do not attempt to 'box in' the boiler or build a compartment around it before consulting

your Installer.

Do not place any combustible material around or on the boiler or flue pipe.

6 Flue terminal - The flue terminal on the outside wall

must not be o

bstructed or damaged.

In severe conditions check that the terminal does not be

come blocked by snow.

7 Frost protection - Your Installer may have fitted

a f

rost thermostat. If not, and you are likely to be away for a short time, leave the boiler on with the boiler thermostat set at a low setting. For longer periods the boiler and system should be drained. Contact your Service engineer for draining and filling the system.

8 Cleaning and servicing - Lightly wipe over the

case with a damp cloth and a little deterg

ent.

Do not use abrasive pads or cleaners. You must have your boiler serviced at least

once a year to ensure safe and efficient operation. Contact your Service engineer for further details.

9 Failure of electricity supply - If the electricity

sup

ply fails, the boiler will not operate. It should

light automatically when the supply is restored.

a programmer is fitted it will retain the time settings for up to 24 hours and will not have to be reset to the correct time of day when the supply is restored (the display remains for up to 1 hour, but will re-appear when the supply is restored).

The boiler requires a 230/240 V ~ 50 Hz supply. It must be protected by a 5 Amp fuse.

Warning: This appliance must be earthed.

If your boiler is operating on a sealed heating system, the installer will have pressurised the system and should have told you (or set it on the pressure gauge) the system pressure when cold (this is normally between 0.5 and 1.0 bar, which will increase slightly when hot). If the pressure (when cold) is below the set pressure mentioned above, you can re-pressurise the system. If the system requires frequent re-pressurising, ask your Installer or Service engineer to check the heating system for leaks and to check the expansion vessel air charge.

The boiler or system will be fitted with an automatic air vent to remove air from the system. Any air trapped in the radiators should be removed by venting the radiators using the vent screw at the top of each radiator. Only vent a radiator if the top is cool and the bottom is hot. Excessive venting will reduce the system pressure, so only vent when necessary and check the system pressure as mentioned above. Repressurise the system if necessary.

2 - USER INSTRUCTIONS

e boiler or system may be fitted with a safety valve to release excess pressure from the system. If water or steam is emitted from the end of the safety valve discharge pipe, switch off the boiler and contact your Installer or Service engineer.

e expansion vessel air charge must be checked annually. Failure to maintain an adequate air charge in the vessel may invalidate the warranty.

To re-pressurise the system by adding water:

1 Only add water to the system when it is cold and

the boiler is off. Do not overfill.

2 Ensure the flexible filling loop (see Fig. B) is

con

nected and that the shut off valve connecting it to the boiler is open and the double check valve at the front is closed. A valve is open when th

e operating lever is in line with the valve, and

d when it is at right angles to it.

3 Gradually open the double check valve on the front

of the filling loop until water is heard to flow. W

hen the black needle of the pressure gauge is

between 0.5 and 1 bar, close the valve.

4 Vent each radiator in turn, starting with the lowest

one in the system, to remove air.

5 Continue to fill the system until the pressure gauge

indicates between 0.5 and 1.0 bar. Close the fill point

valve.

6 Repeat steps 4 and 5 as required.

7 Close the valves either side of the filling loop and

disconnect the loop.

4.2

Boiler components

The

iQE Horizon Internal range of automatic pressure jet oil boilers have been designed for use with a fully pumped central heating system with indirect domestic hot water cylinder. They are not suitable for use with either a direct cylinder or a 'primatic' cylinder or gravity hot water. The boilers are suitable for use on open vented or sealed central heating systems. System models are supplied with the necessary components factory fitted. See Section 4.13. All models are supplied with the control panel and burner factory fitted. The boilers can be connected to either a conventional flue system or a balanced flue system, as required.

For Conventional flue applications where a chimney is to be lined - iQE recommends the use of the O-system, specifically designed for the Internal range of iQE Horizon oil boilers. Refer to Section 4.7 for further details.

Where a rigid conventional flue - either internal or external - is required, iQE recommends the use of the G and O flue system components. As no flue adaptor is supplied with the boiler it will be necessary to purchase the iQE Horizon adaptor kit in order to correctly connect the G and O system flue components to the boiler.

Flue adaptor kit - Ref. iQE CF15/35 - is used for all iQE models from 15 to 35 kW as they all can use the 100 mm G and O system components to construct a flue of maximum vertical height 8 metres.

Important: The flue system materials and construction MUST be suitable for use with oilfired condensing boilers. Failure to fit a suitable conventional flue may invalidate the warranty on the boiler.

Fitting instructions for the Low level concentric, High level and Vertical balanced flue kits are supplied with the kits. Where a balanced flue system is required, the following flue kits are available from iQE, Refer to Section 4.8 for further details.

1 When the storage tank outlet is below the burner,

the two pipe system should be used. The pipe runs should be as shown in Fig. 4. The return p

ipe should be at the same level in the tank as the supply pipe, both being 75 to 100 mm above the base of the tank. The pipe ends should be a sufficient distance apart so as to prevent any sediment disturbed by the return entering the supply pipe.

2 Avoid the bottom of the tank being more than 3 m

below the burner.

3 A non-return valve should be fitted in the supply

pip

e together with the filter and fire valve. A non-return valve should be fitted in the return pipe if the top of the tank is above the burner.

4 T

o be used with a two-pipe system,

the burner must be fitted with an additional flexible fuel hose and a male adaptor. They are

available to purchase from iQE. Part No. iQELINE / iQE3814

5 The pump vacuum should not exceed 0.4 bar.

Beyond

this limit gas is released from the oil.

4 - GENERAL BOILER INFORMATION

It should be both the designer's and installer's concern that the air required for these functions be introduced s

o as to cause as little discomfort as possible to the building occupants and thus to offer them the least temptation to obstruct the ventilators. Further details may be obtained from BS 5410:1:19

97.

Notes:

For a boiler fitted in a compartment, which is v

entilated as shown, no additional allowance is necessary. Open flue - Extract fans, where needed, should be in accordance with Section 4.4.7 in BS 5410 Part 1 1997. All ventilation areas given are for domestic applications. For all other cases refer to BS 5410 Part 2 1978.

Under no circumstances can iQE Horizon boilers be installed with existing flue systems. Only flue systems and components suitable for wet flues should be used. Failure to install the correct type of flue system will invalidate the warranty.

See Fig. 10a and 10b General iQE

Horizon condensing boilers have high operating efficiencies and low flue gas temperatures. Care must be taken to ensure the flue system is suitable for the very low flue gas temperatures and condensate in the flue gases. Suitable conventional flue systems (O-system) are available from iQE - see Fig. 10a.

1 The flue must terminate in a down

draught free area, i.e. at least 600 mm above the point of exit through t

he roof or preferably above the ridge level.

2 The condensate may be allowed to run back into

the boiler. A condensate drain at the base

the flue system is not required.

3 Th

e flue terminal must be at least 600 mm from any opening into the building, and 600 mm above any vertical structure or wall less than a horizontal distance of 750 mm from the terminal. See Fig. 11.

4 If an existing chimney is to be used, it must be lined

with a smooth bore stainless steel liner suitable for use with oil fired condensing boilers. The top and bottom of the annular space must be sealed. The internal flue and liner diameter for all models must be 100 mm (4 in).

QE recommends the use of the iQE 'O' flue

system; specifically designed for the Internal range of condensing boilers. Refer to Section

4.7 for further details. The maximum vertical height (from the top of the boiler to the terminal) for the iQE 'O' system is 19 metres.

5 If a r

igid flue is used internally or externally,

it must be of the twin-wall type incorporating seals

at all joints, constructed with a stainless steel inner skin and be suitably insulated and weatherproofed. iQE recommends the use of the G flue system components for this application. Refer to Section 4.1 for details. The internal flue diameter for a rigid flue for all models is 100 mm (4 in). Note: As no flue adaptor is supplied with the boiler it will be necessary to purchase the iQE CF adaptor kit (Ref. iQE CF15/35) in order to correctly connect the G-system flue components to the boiler. If required, it is possible to use the white painted single-wall straight flue extensions, adjustable extensions and elbows from the iQE Osystem for the internal section of the flue system, see Fig 10b. These components can be fitted between the boiler connector and flue adaptor. The flue adaptor, to which the external twin-wall G-system components are connected, can therefore be situated just before the flue system passes through the wall. Note: iQE O-system single-wall flue components must not be used externally. The maximum vertical height (from the top of the boiler to the terminal) for the 100 mm diameter G-system twin-wall flue is 8 metres.

6 Twin-wall flues are recommended for externally

run flues to reduce the possibility of the condensate freezing in the flue.

7 No part of any flue system should be made of an

asbestos material; alumini

um must not be used in any part of the flue. Only stainless steel flue components should be used.

8 If the draught conditions are satisfactory, the flue

should terminate with a standard cowl.

9 Refer to the locally applicable Building

Regulations, BS 5410:1 and OFTEC Installation Requirements (Books 2 and 3) for further guidance on conventional flue systems.

It is important to ensure that the flue system is sealed and that condensate cannot escape. Up to

1.5 l/h of condensate can be produced in a conventional flue system.

ly use flue systems suitable for oil fired

condensing boilers.

Do not use fire cement. The use of high temperature silicone sealants is recommended.

Apa

rt from a conventional flue, several balanced flue options are available for use with the iQE Internal boilers. All are suitable for use with Class C2 kerosene.

Note: None of the flue sections in the following system can be cut.

1 Low level horizontal balanced flue (iQE Y-system)

Available in Short (for single thickness brick walls) and Standard kits.

Extensions are available which extend the flue by 225 mm, 450 mm or 675 mm. 90° and 45° elbows are also available.

The

maximum flue length - from the centre of

the boiler flue outlet to the outer face of the wall

- is 4 metres (with or without elbows included). No more than 2 x 45° or 1 x 90° elbow should be fitted per system.

2 High level balanced flue (iQE W-system)

Allows the flue to rise vertically within the building before exiting through the wall horizontally.

The maximum flue length - from the top of the boiler flue outlet to the outer face of the wall is 10 metres for all iQE boilers.

Extensions are available which extend the flue by 225 mm, 450 mm or 950 mm. An adjustable extension of 275 to 450 mm is also available.

A 45° elbow is also available. No more than 6 x 45°elbows should be fitted per system. Each elbow reduces the overall maximum length of the system by 1 metre.

3 Vertical balanced flue (iQE W-system)

Allows the flue to rise vertically from the boiler to exit through the roof.

The maximum flue length - from the top of the boiler flue outlet to the terminal - is 12 metres for all iQE boilers.

Extensions are available which extend the flue by 225

mm, 450 mm or 950 mm. An adjustable

extension of 275 to 450 mm is also available.

A 45° elbow is also available. No more than 6 x 45° elbows should be fitted per system. Each elbow reduces the overall maximum length of the system by 1 metre.

4 External balanced flue (iQE G-system)

Where it is not practical to use a low level (iQE Y-system) or internal high level/vertical (iQE W-system) balanced flue, the boiler can be fitted with an external vertical/high level flue (iQE G-system). See Fig. 10c.

he Starter kit fits to the boiler in the same

way as a low level balanced flue (iQE Ysystem) and the external Tee allows the connection of a twin wall insulated flue pipe and a combustion air inlet -providing a room sealed flue system. The external system can terminate at either high level or vertically (above roof level) as required. See Fig. 10c.

The minimum dimensions for locating the t

erminal from building features (windows, doors,

etc.) are shown in Fig. 11.

If the

flue terminal is fitted less than 2 metres above a surface to which people have access, the terminal must be protected by a guard. The guard must be fitted centrally over the flue terminal and securely fixed to the wall.

The low level balanced flue (iQE Y-system) is supplied with a stainless steel guard. This must be fitted in all circumstances to prevent objects from entering the flue outlet.

The

terminal must be positioned so as to avoid products of combustion accumulating in stagnant pockets around the buildings or entering into buildings. Care should be taken that the plume from condensed flue gases does not cause a nuisance.

lexible vertical balanced flue (iQE R-system)

This is a flexible vertical balanced flue system (for the 15/26 models only) designed to be fitted inside an existing masonry chimney. See Fig. 10d. It basically consists of three sections:

Concentric white painted flue pipe connected to the boiler Vertical concentric flexible flue (flexible stainless steel flue liner inside a flexible plastic air inlet liner) Terminal assembly for chimney top mounting

The flue pipe seals are factory fitted and must be lubricated with the lubricant supplied before assembly.

e iQE R-system is supplied as a separate kit.

Flue extensions and 45° elbows from the White system may be used to extend the flue

between the boiler and the flexible section of the system.

The maximum vertical straight length of flue, from the top of the boiler to the top of the terminal, is 20 metres using no more than four 45° elbows. Deduct 1 metre of straight flue length for every elbow used.

Note: If the flexible liners have to pass around an offset inside the chimney deduct 2 metres of straight flue length to compensate for this.

4 - GENERAL BOILER INFORMATION

lue extensions cannot be cut, use adjustable extensions where required. Three types of locking band are supplied with the kit. The first type is painted white and is for connecting flue sections that butt together (2 of this type of locking band are supplied). The second type, also painted white, is to cover the joint on the adjustable (telescopic) section.

Note: The locking band for the adjustable section is labelled for easy identification.

The third locking band is plastic and supplied in two halves. This is to secure the plastic flexible liner to the adapter.

The flue kit includes a Black coated terminal with upstand and is designed to be fixed (using the screws provided) to the top of a masonry chimney.

The flue system may be offset using 45° elbows (ref. iQE90EX45ELB). No more than a maximum of four elbows should be used per system.

Notes:1 An opening means an openable

element, such as an openable window, or

a permanent opening such as a permanently open air vent.

2 Notwithstanding the dimensions

given, a terminal should be at least 300 mm from combustible material, e.g. a window frame.

3 A way of providing protection of

combustible material would be to fit a heat shield at least 750 mm wide.

Where the frost thermostat is installed outside the house (to protect a boiler installed in an external boiler room or garage) or in an attic, it is recommended that it be used in conjunction with a pipe thermostat to avoid unnecessary and wasteful overheating of the property. The pipe thermostat should be located on the boiler return pipe, and set to operate at 25° C. Refer to Section 10 for connection details.

For additional protection of either the entire heating sy

stem, or the boiler and localised pipework, it is recommended that a frost thermostat be installed. Refer to Section 10 for connection details. To protect the heating system, the frost thermostat should be sited within the house in such a place that it can detect any rise and fall in the ambient air temperature, i.e. in a room with a radiator.

The Installer must e

nsure that the terminal does not

cause a

nuisance.

Frost protection

Page 25

4 - GENERAL BOILER INFORMATION

1 The boiler must stand on a surface that is firm and

level. It does not require a special hearth as the temperature of the boiler base is less than 50° C.

2 Sufficient clearance must be allowed at the front of the

boiler to remove the burner and baffles for servicing.

3 Once the boiler has been installed, a permanent

workt

op may be fitted over it as access to the top

of the boiler is no longer required after installation.

Sealed system kit fitted - A removable section of worktop above the boiler is required to provide access for servicing.

IMPORTANT: All pipes to be fitted into the push-fit connectors provided should be cut using a pipe slicer or pipe

cutter to leave the pipe ends with a slight radius and free from any burrs or sharp edges. Pipes to be used with these fittings should not be cut square using a hacksaw.

All models

To avoid the danger of dirt and foreign matter entering the boiler the complete heating system should be thoroughly flushed out - before the boiler is connected and then again after the system has been heated and is still hot. This is especially important where the boiler is used on an old system.

For optimum performance after installation, this boil

er and its associated central heating system must be flushed in accordance with the guidelines given in BS 7593:1992 'Treatment of water in domestic hot water central heating systems'.

This must involve the use of a proprietary cleaner, such as Sentinel X300 or X400. Full instructions are supplied with the products, but for immediate information, please contact Sentinel on 01928 588330.

For Long term protection against corrosion and scale, after flushing, it is recommended that an inhibitor such as Sentinel X100 is dosed in accordance with the guidelines given in BS 7593:1992.

Failure to implement the guidelines will invalidate the warranty.

To reduce the operating temperature of the expansion vessel diaphragm, position it below the pipe to which it is connected. The expansion vessel may be positioned away from the system, providing the connecting pipe is not less than 13 mm diameter.

4 The pressure gauge should have an operating

range of 0 to 4 bar.

5 The safety valve, set to operate at 2.5 bar, should

be fitted in the flow pipework near to the boiler. The pipework between the safety valve and boiler must

be unrestricted, i.e. no valves. The safety valve should be connected to a discharge pipe which will allow the discharge to be seen, but cannot cause injury to persons or property.

6 Provision should be made to replace water lost

from the system. This can be done manually (where allowed

by the local water undertaking) using an approved filling loop arrangement incorporating a double check valve assembly.

7 An automatic air vent should be fitted to the

highest point of the system.

8 The system design pressure (cold) should be

between 0.5 and 1.0 bar. This pressure is equivalent to the maximum static head in bar +

0.3 (1 bar = 10.2 metres of water).

9 All fittings used in the system must be able to

withstand pressures up to 3 bar.

10 Radiator valves must comply with the requirements

of BS 2767(10):1972.

11 One or more drain taps (to BS 2879) must be used

to allow the system to be completely drained.

12 For proprietary expansion vessel/valve/gauge

packs, refer to the manufacturers instructions for the correct location on the heating system.

1 A 15 mm discharge pipe must be connected to

the safety valve outlet connection. The pipework between the safety valve and the boiler must be unrestricted, i.e. no valves. The discharge pipe should be run to the outside of the building and terminate so that it cannot cause injury to persons or property.

2 A 15 mm double check valve ballofix type valve is

provided on the flexible filling loop hose for connection of the cold mains supply to the heating system. The cold mains supply should terminate inside the boiler casing.

3 The expansion vessel is connected via a flexible

hose to allow it to be moved to gain access to the baffle cleaning cover. When replacing the vessel, care should be taken to ensure that the flexible connecting hose is not twisted.

On underfl

oor systems it is essential that the return temperature must be maintained above 40° C to prevent internal corrosion of the boiler water jacket.

General - iQE Horizon boilers are

compatible with both copper and plastic pipe. Where plastic pipe is used it must be of the oxygen barrier type and be of the correct class (to BS 7291:Part 1:1990) for the application concerned.

IMPO

RTANT: The first metre of pipework connected to both the heating flow and return connections of the boiler must be made in copper on all types of system - sealed or open-vented.

4 - GENERAL BOILER INFORMATION

When in condensing mode the iQE boilers produce condensate

from the water vapour in the flue gases. This condensate is slightly acidic with a ph value of around 3 (similar to vinegar). Provision must be made for the safe and effective disposal of this condensate.

Condensate can be disposed of using one of the following

methods of connection:

Internal connection (preferred option)

•

into an internal do

mestic waste system

(from kitchen

sink, washing machine, etc.)

•

directly into the soil stack

External connection

• into an external soil stack

• into an external drain or gulley

• into a rainwater hopper (that is part of a

combined system where sewer carries both rainwater and foul water)

• purpose made soakaway

All condensate disposal pipes MUST be fitted with a trap - whether they are connected internally or externally to a domestic waste system/soil stack or run externally to a gully, hopper or soakaway.

Connections into a rainwater hopper, external d

rain or gulley should be terminated inside the hopper/drain/gulley below the grid level but above the water level.

Condensate disposal pipes should not be connected directly into rainwater downpipes or to waste/soil systems

connected to septic

tanks. Condensate should not be discharged into 'grey

water' syst

ems that re-use water used in the

home (not including water from toilets).

It should be noted that connection of a condensate pipe to the drain may be subject to local Building Control requirements.

Condensate disposal pipework must be plastic (p

lastic waste or overflow pipe is suitable).

IMPORTANT: Copper or steel pipe is NOT suitable and MUST NOT be used.

Condensate disposal pipes should have a minimum 'nominal' diameter of 22 mm (¾") e.g. use 21.5 mm OD polypropylene overflow pipe.

Condensate disposal pipes must be fitted with a fall (away from the boiler) of at least

2.5° (~45 mm fall per metre run).

5 - CONDENSATE DISPOSAL

The sy

stem should incorporate a low-pressure switch to shut off power to the boiler if the system pressure drops below 0.2 bar. A suitable low pressure switch kit is available to purchase from iQE Part No. iQE CF15/35

Underfloor systems - Plastic pipe may be used on Underfloor systems where th

e plastic pipe

is fitted after the thermostatic mixing valve. Copper tube m

ust be used for at least the first metre of flow and return primary pipework between the boiler and the underfloor mixing/blending valves.

Note: Where it is not possible for the pipe to fall towards the point of discharge - either internally into a waste system or externally to a gulley (e.g. for boilers installed in a basement), it will be necessary to use a condensate pump.

ondensate disposal pipes should be kept as short

as p

ossible and the number of bends kept to a

minimum.

Pipes should be adequately fixed to prevent sa

gging, i.e. at no more than 0.5 metre intervals.

External pipework

Ideally, external pipework, or pipework in unheated areas, should be avoided. If unavoidable, external pipework should be kept as short as possible (less than 3 metres) and 32 mm waste pipe used to minimise the risk of ice blocking the pipe in freezing conditions. The number of bends, fittings and joints on external pipes should be kept to a minimum to reduce the risk of trapping condensate.

Note: For boiler installed in an unheated area such as an outhouse or garage, all condensate pipework should be considered as an ‘external’.

5 - CONDENSATE DISPOSAL

To keep external pipework to a minimum, locate the soakaway as close as possible to the boiler but ensure it is

at least 1 metre from building foundations and away from other services, e.g. gas, electricity, etc.

The condensate pipe may be run above or below ground level and can enter either the top or side of the soakaway tube. Refer to Fig.14.

Ensure t

hat the drainage holes in the soakaway

tube face away from the building.

Backfill both the soakaway tube, and the hole around it,

with 10 mm limestone chippings.

Only use a soakaway where the soil is porous and drains easily. D

o not use in clay soils or where the

soil is poorly drained.

WARNING: Any damage due to condensate backing up into the boiler due to a high water table, in

the case of a soakaway, or flooded drains when the condensate disposal is via a gulley or soil stack, is not covered by the iQE product warranty.

5 - CONDENSATE DISPOSAL

iQE boilers are supplied with a factory-fitted condensate trap to provide the required 75 mm water seal in the condensate discharge pipe from the boiler.

This trap incorporates a float (which will create a seal when the trap is empty) and an overflow warning outlet (fitted with a plastic sealing cap), See Fig. 15.

Care should be taken when siting the trap such that the overflow outlet is readily visible and that any condensate overflowing from the outlet cannot cause either a hazard to persons or damage to surrounding property or equipment.

The condensate trap outlet is at an angle of 48° below the horizontal. This is to automatically give a 3° fall on any 'horizontal' runs of condensate disposal pipe. Refer to Fig.15.

The outlet of the trap will accept 21.5 mm to 23 mm OD Polypropylene overflow pipe for the condensate discharge pipe.

This discharge pipe can exit through the left hand side of the boiler through one of pre-cut 'knock-outs' in the casing panel (see to Fig. 1). Push out the 'knock-out' from the required hole taking care not to distort the side panel.

The trap MUST be checked at regular intervals (e.g. on every annual service) and cleaned as necessary to ensure that it is clear and able to operate.

Note: The bottom bowl is sealed to the trap body and cannot be removed.

To inspect and clean the trap:

1 Disconnect flexible condensate hose from inlet

connector.

2 Unscrew

the inlet connection nut.

3 Remove the inlet connector and nut from trap.

4 Remove trap from bracket.

5 Remove float from trap – clean if necessary.

6 Inspect inside

of trap and clean as necessary.

7 Re-assemble trap, re-fit to boiler and re-connect

flexible hose. Ensure that hose is fully pushed onto the trap inlet connector.

IMPORTANT: Failure

to regularly check and clean the condensate trap may result in damage to the boiler and will not be covered by the Product Warranty.

Fig. 15 - Condensate trap

The

trap is factory-fitted inside the boiler casing (mounted on the inside of the left side panel) in an accessible position to allow for routine maintenance.

Note: If required, this condensate trap may be relocated outside the boiler casing. Refer to procedure given in 'external condensate trap'. This procedure MUST be carried out before the boiler is installed.

A flex

ible hose connects the outlet of the condensing heat exchanger to the trap inlet. Ensure the straight connector on the hose is fully pushed onto the 'top hat' inlet connector of the trap.

ith the trap fi

tted inside the boiler casing, the

sealing cap MUST be f

itted. If the trap is re-located

outside the boiler then the following applies:

If connecting the condensate discharge (either internally or externally) into a waste system or soil stack - the sealing cap MUST be fitted in the trap outlet.

On external discharge systems to a hopper, gully or soakaway, the sealing cap should be removed from the trap outlet.

If there is any discharge of condensate from the overflow outlet, this could indicate a blockage (possibly due to freezing). Turn off the boiler and investigate the cause. If necessary contact your service engineer for assistance.

To re-locate the factory-fitted trap outside the boiler casing,

use the following procedure:

Note: This procedure must be carried out before the boiler is installed.

1 Remove the top casing panel(s) from the boiler.

2 Unscrew and remove the screws fastening the left

side panel to the rear casing panel of the boiler.

3 Carefully separate the left side and rear panels

just enough to gain access to the condensate outlet on the left rear of the condensing heat exchanger (see Fig.16).

4 Push out pre-cut 'knock-out' from the condensate

outlet hole in the rear of left side casing panel.

5 Remove the right angle end of the flexible

cond

ensate discharge hose from the outlet

connection on the condensing heat exchanger.

6 From the front of boiler, remove the straight

connector end of the flexible hose from the top of the condensate trap.

7 Reverse the flexible hose and pass the

straight connector end through the new hole in the left hand casing panel. Push the straight connector firmly onto the condensate outlet connection of the condensing heat exchanger

- push on at least 20 mm.

8 Refit the left hand casing panel to the rear panel

using the reverse procedure, ensuring all fixing screws are used.

9 Remove the trap from the mounting bracket.

10 Unscrew and remove the trap mounting bracket

from the left side panel.

11 Fix the trap mounting bracket to the wall adjacent

to the boiler in the required position.

Note: The top of the trap must be below the condensate connection on the boiler.

12 Re-fit the trap to the mounting bracket.

The mounting bracket supplied with the trap MUST be used - the trap should NOT be supported by the condensate pipework only.

13 Connect the flexible condensate hose to the trap,

pushing the right angle hose connector onto the trap inlet connection.

IMPORTANT: The flexible

hose must fall continuously

from the outlet to the top of the trap.

Refer to Section 4.11 and 4.12 and Fig. 12. for the size, type and position of the connections.

The Flow and Return pipework can be routed to either side of the boiler, dependant on the type and direction of the flue system used.

For condensate disposal pipework refer to Section 5.

IMPORTANT: All pipes to be fitted into the pushfit connectors provided should be cut using a pipe slicer or pipe cutter - to leave the pipe ends with a slight radius and free from any burrs or sharp edges. Pipes to be used with these fittings should not be cut square using a hacksaw.

Pipe entry/exit holes in case

All models have holes to enable the pipework to exit the boiler casing. On the 15/21 and 21/26 models these holes are pre-cut knock-outs located at the rear of both side panels and on the 26/35 model these pre-cut holes are in the removable flue outlet cover plates. Push out the 'knock-out' from the required holes, taking care not to distort the side panel. If access will be restricted, make any connections to the boiler before placing it in its final position. If using a balanced flue system - Install the balanced flue system before connecting the heating system pipework to the boiler. Once the flue system is fitted then complete the water connections and fill the heating system. If using a conventional flue system - Complete the water connections and fill the heating system. Check all connections for leaks and rectify as necessary. If the iQE sealed system kit is fitted, refer to Section 6.6 for details on filling and venting the sealed heating system.

the boiler combustion door locating the vessel bracket into cut-out in the front of the combustion door.

Note: on 15/26 model press on the pre-cut section in the centre of the door to form the cut-out for the bracket.

8 Fit the ¾" BSP connection of the flexible expansion

vessel hose to the vessel using the black rubber washer supplied

and tighten the nut.

9 Fit the pump support bracket to the vertical plate

on top of the boiler shell. Fasten in place using the scre

w, nut and washer provided.

10 Push the 22 mm push-fit elbow onto the boiler flow

connection.

11 Push the automatic air vent/pressure relief valve

assembly into the push-fit elbow.

12 Fit both 22 mm pump valves to the circulating

pump using the sealing washers supplied.

13 Fit the pump assembly to the automatic air vent/

pressure relief valve assembly ensuring that the pump shaft is horizontal, the pump motor is facing towards the front of the boiler and the body is resting on the pump support bracket. The flow arrow on the body of the pump must face in the direction of flow away from the boiler connection.

14 Fit the pressure relief valve discharge pipe to the

pressure relief valve using the nut and olive supplied. Route the discharge pipe through the slot in the base of the right hand side panel. Push the panel insulation back to expose the slot.

15 The circulating pump may be wired into the boiler

control panel if required. Refer to Section 10.

16 Re-fit the burner and tighten the fixing nut to secure.

17 The filling loop should be connected, via the

double check valve, to a 15mm cold water supply pipe from the mains at a convenient position inside the boiler.

The expansion vessel fitted, is supplied with a charge pressure of 1.0 bar (equivalent to a max. static head of

10.2 metres). The charge pressure must not be less than the actual static head at the point of connection. Do not pressurise the vessel above 1.5 bar.

The air pressure in the vessel must be checked annually.

The c

entral heating system volume, using the expansion vessel as supplied, must not exceed the recommended volumes. If the system volume is greater, an extra e

xpansion vessel (complying with BS 4841) must be fitted as close as possible to the central heating return connection on the boiler. The charge pressure of the extra vess

el must be the same as the vessel fitted in the boiler.

Refer to BS 7074:1 for further guidance.

The air charge pressure may be checked using a tyre pressure gauge on the expansion vessel Schraeder valve. The vessel may be re-pressurised using a suitable pump. When checking the air pressure the water in the heating system must be cold and the system pressure reduced to zero.

It is recomm

end that the boiler should be connected to a switched mains power supply from a programmer or control system. Refer to Sections 10 for typical control system wiring diagrams.

1 Lift off the boiler case top panel, if it has not

already been removed.

2 Remove the top of the control panel and open the

cab

le clamp. Route the supply cable through the hole in the rear panel (using the grommet supplied) up to the control panel, pass it through the cable clamp and connect to the boiler terminal block (refer to Section 10) as follows:-

Brown to liv

e (terminal 1) Blue to mains neutral (terminal 2) Green/ Yellow to mains earth (terminal 3)

ote: E

sure that the route and length of the cable is such that the boiler front cover plate can

be easily removed without disconnecting

the supply cable from the terminal block.

3 Secure the cable in the cable clamp.

4 Place the wiring cover in position over the terminal

block,

taking care not to trap any wires and secure

in position with the two M4 screws provided.

5 Ensure that all external wiring is adequately supported.

Do not switch on the electricity supply at this stage.

See Fig. 7

If a two pipe system is to be used refer to Section 4.4.6.

1 Remove the oil inlet plug from the fuel pump and

connect the elbow of the flexible fuel hose supplied with the boiler.

2 Connect the flexible fuel hose to the rigid

supply using the adaptor supplied. The supply enters through one of the holes in the casing plinth.

1 Automatic air vent(s) are fitted to the top of the

boil

er. Check that the small cap on the top of each air vent is screwed on fully, then unscrew it one complete turn - the cap remains in this position from now on.

2 If the flexible filling loop is used to fill the system, ensure

it is connected and that the valve connecting it to the boiler is

open and the valve at the front is closed. A valve is open when the operating lever is in line with the valve, and closed when it is at right angles to it.

3 Ensure that the mains cold water supply valve is open

(operating lever in line with the valve), then turn on the mains

cold water supply and gradually open the front valve on the filling loop until water is heard to flow.

4 Vent each radiator in turn, starting with the lowest

one in the system, to remove air.

5 It is important that the pump is properly vented to

avoi

d it running dry and damaging its bearings. To gain access to the pump for venting it is necessary to remove the control panel. Loosen the four fixing screws securing the panel to the casing, push the panel towards the rear of the boiler and lower the control panel to expose the pump. Remove the cap, then unscrew and remove the plug from the centre of the pump. Using a suitable screwdriver rotate the exposed spindle about one turn. Replace the plug and cap.

6 Check the operation of the safety valve by turning

the head anticlockwise until it clicks. The click is the s

afety valve head lifting off its seat allowing water to escape from the system. Check that this is actually happening.

7 Continue to fill the system until the pressure gauge

ind

icates between 0.5 and 1.0 bar. Close the fill point valve and check the system for water soundness, rectifying where necessary. Water may be released from the system by manually operating the safety valve until the system design pressure is obtained.

8 The system design pressure (cold) should be

betw

een 0.5 bar and 1.0 bar. The pressure is

equivalent to the maximum static head in bar +

0.3 (1 bar = 10.2 metres of water), where the static head is the vertical height from the centre of the expansion vessel to the highest point of the system.

9 Close the valves either side of the filling loop and

disconnect the loop.

9 Check the operation of the boiler thermostat.

Ensure that by turning it anticlockwise it switches the burner off.

10 With the burner alight, re-check the fuel pressure

and r

e-adjust if necessary. Turn the boiler off, remove the pressure gauge and replace the plug in the pump.

11 Having ensured that there are no oil leaks, replace the

burner cover. Ensure the flexible air tube is con

nected to the burner (balanced flue models).

12 Relight the boiler and allow it to run for at least 20

minutes.

13 Check the smoke number, if satisfactory check

the CO2. Set the CO2 to the value given in Section 3.3 for the boiler concerned.

Use the hexagonal key supplied to adjust the burner air

damper (see Fig. 20) as required. Turning the screw anti-clockwise closes the damper and increases CO2 level, turning the screw clockwise opens the damper and reduces CO2 level.

Re-check the smoke number if the damper has been moved. Under no circumstances must the smoke number be above 1.

Note: It is important that the air damper is correctly set.

14 Check the flue gas temperature.

15 Check that both the boiler overheat and boiler

conmtrol thermostat bulbs are correctly located in their respective pockets. For location of thermostat pockets, refer to Fig. 12. Also check the condition of both thermostat capillaries, i.e. that they are not damaged, broken or kinked, and that they are not trapped or crushed between any internal boiler components.

16 Replace the case top.

17 When the boiler has been adjusted and is running

satisfactorily, balance the central heating system by adjusting the radiator lock shield valves. Start

with the radiator nearest the boiler and adjust the valves to achieve the required temperature drop across each radiator. If thermostatic radiator valves have been installed, check the system by-pass.

18 Switch off the boiler.

19 With the system hot, check again for leaks,

rectifying where necessary. Drain the system while it is hot to complete the flushing process. Refill and vent (and pressurise if a sealed system) the system.

20 A suitable central heating system inhibitor

must be added to protect the system against the effect of corrosion.

21 Replace the front panel - Locate the bottom of

the panel over the fixing tags then push it towards the boiler to engage the fixing clips.

Note: After commissioning the boiler complete the Commissioning Report on page 2 of these instructions and the OFTEC CD/11 commissioning report. Leave the top copy with the User and retain the carbon copy.

using this test point. The test point is not suitable for measuring boiler efficiency or conventional flue draught.

When using the test point on the cleaning cover note that the flue gas temperature reading will be higher than that measured in the flue thus resulting in an inaccurate efficiency reading. To obtain an accurate flue gas temperature and efficiency, the reading can only be measured outside through the low level flue terminal. For high level and vertical balanced flues the reading may be taken from the flue kit test point provided . Refer to Section 3.3.

For Conventional flue draught measurement and efficiency a test point is provided in the conventional flue adaptor.

To adjust the 15/26 air adjuster disc when downrating - See Fig. 22

Ensure the boiler is isolated from the electrical supply.

Disconnect the air supply tube.

Remove the burner from the boiler.

Undo the two screws and remove the air inlet cover from the side of the burner.

The secondary air shutter disc is factory set in position ‘C’ – i.e. with the cut-out marked C located against the die-cast boss on the fan housing - suitable for outputs of 18.3 and 21 kW only. See Fig 22.

14 - HEALTH AND SAFETY INFORMATION

Under the Consumer Protection Act 1987 and Section 6 of the Health & Safety at Work Act 1974, we are required to provide information on substances hazardous to health (COSHH Regulations 1988). Adhesives, sealants and paints used in the manufacture of the product are cured and present no known hazards when used in the manner for which they are intended. The following other materials are present in the product:

Insulation materials

Material Types: Ceramic fibre board, mineral wool.

Description: Rigid board, slabs, sleeves, gaskets, ropes.

Known Hazards: May cause temporary irritation or rash to skin. High dust levels may irritate eyes

and upper respiratory system.

Precautions: Avoid unnecessary or rough handling, or harsh abrasion of boards. Normal

handling and use of material should not produce high dust levels. Avoid inhalation, and contact with skin and eyes. After handling always follow normal good hygiene practices.

Protection: Use disposable gloves, face mask and eye protection.

First Aid: Eyes - If irritation occurs, wash eyes with copious amounts of water. If

symptoms persist, seek immediate medical advice. Skin - If irritation occurs, wash under running water before washing with soap and water. Inhalation - Remove to fresh air, drink water to clear throat and blow nose to remove dust/fibres. Ingestion - Drink plenty of water.

Sealants

Material Types: Silicone elastomer.

Description: Sealant and adhesive.

Known Hazards: Irritation to eyes.

Precautions: Avoid inhalation of vapour, contact with eyes and prolonged or repeated contact with

skin. After handling always follow normal good hygiene practices.

Protection: Use eye protection. Rubber or plastic gloves should be worn where repeated

contact occurs and a face mask worn when working in confined spaces.

First Aid: Eyes - Flush eyes with water for 15 minutes. Seek immediate

medical attention. Skin - Wipe off and wash with soap and water. Inhalation - Remove to fresh air.

Kerosene and Gas oil fuels (Mineral oils)

Known Hazards: The effect of mineral oils on the skin vary according to the duration of exposure

and the type of oil. The lighter fractions remove the protective grease naturally present on the skin, leaving it dry, liable to crack and more prone to damage by cuts, abrasions and irritant chemicals. Skin rashes (Oil acne) most often on arms, but also on any part of the body in contact with oil or oily clothing. Contact with fuel oils can cause dermatitis.

Precautions:

Avoid as far as possible any skin contact with mineral oil or with clothing contaminated with mineral oil. The

use of a lanolin-based barrier cream is recommended, in conjunction with regular washing with soap and rinsing with water to ensure all oil is removed from the skin. Take care to prevent clothing, especially underwear, from becoming contaminated with oil. Do not put oily rags or tools in pockets, especially trouser pockets. Have first-aid treatment at once for an injury, however slight. Do not inhale any vapours from mineral oils.
