3.3 Data plate

3.2 Operation

The Intergas Xtreme is a modulating high eiciency boiler. This means that the capacity is adjusted according to the desired heating capacity. Two separate copper circuits are integrated in the aluminium heat exchanger. In addition, the Intergas Xtremehas a second heat exchanger (heat recovery unit). This second heat exchanger is integrated in the flue of the boiler so that the eiciency of domestic hot water is increased further. The residual heat of the flue gases of the central heating use is also used to preheat the domestic hot water. By applying this technology, less energy is required to bring the water to the correct temperature and an extremely high eiciency is achieved.

The boiler has a burner controller which, with each heat demand of the heater or the domestic hot water facility, controls the pump (only during heat demand of the heater) and the fan, opens the gas valve, ignites the burner and continuously monitors and regulates the flame, depending on the requested capacity.

4 INSTALLER IMPORTANT POINTS

Please read all instructions before fitting this appliance

► The installer shall instruct the user on the operation of the boiler, safety devices contained within

the boiler and on the location of the filling loop and how to re-pressurise the system if the water

pressure falls. ► The installer should hand over the installation and user instructions upon completion with the

completed Benchmark Commissioning Checklist. ► The service engineer must complete the service record on the Benchmark Checklist aer each

service. ► It is required under Gas Safe Regulations for the installation to be notified to and registered with

Gas Safe, Intergas and Building Control (Gas Safe Notifcation). ► Before proceeding to commission the boiler check the gas inlet pressure is 20mbar (NG) or

37mbar for Propane. ► Combustion analysis with a correctly calibrated and certificated analyser is essential for safe

commissioning of the boiler. ► A pressure reducing valve set to 3.5 bar must be fitted if supply mains pressure is above 4 bar. ► In hard water areas where the PH is 200ppm or above, appropriate protection actions must be

taken in accordance with BS 7593 in line with building regulations Part L.

See also Guarantee Provisions on page 75, point 4. ► The user should be instructed to keep the instructions in a safe place for servicing and future

reference. ► It is important to keep the boiler clear of dust during the installation. In particular, do not allow

debris to enter the flue connection at the top. ► Before fitting the boiler ensure that the pipe work that you are installing is connected to the

appropriate connections on the boiler.

It is important to thoroughly flush the water circuits, aer isolating the boiler, in order to remove

any fluxes and debris from them. This should be done particularly where boilers are being fitted to

existing radiator circuits (please refer to current Standard Codes of Practice). ► Intergas recommend water treatment in accordance with the Benchmark Guidance on Water

Treatment in Central Heating Systems, we recommend the use of FERNOX, SENTINEL or ADEY

inhibitors. It is most important that correct concentration of water treatment is maintained

for the life of the boiler, a water sample is required on installation and to be verified by the

aforementioned manufacturers should we attend a warranty call a water sample may be required

to keep the warranty valid. (BS 7593:2006) ► This boiler has been factory set but adjustment may be required to the heating input in order to

match the individual heating demand. This can be done by changing parameter P010 (= max.

power CH) or parameter P070 (= max. power domestic water). ► Please do not use the pressure relief valve as a means of flushing the system. ► Remember that aer hot water draw of a possible delay may occur before the heating system will

fire up. ► All fluxes, residues and cleaner must be flushed from pipe-work and radiators prior to

commissioning. ► External expansion vessels are best connected water side downwards to allow correct draining/

cleaning of system and to prolong the life of the vessel diaphragm. ► Note: an anti-cycle delay time can be set up to a maximum of 15 minutes by adjusting parameter

P036 as described in §8.3. ► If you experience any problems please refer to the installation and commissioning guidelines

within the boiler instruction manual. If necessary, please contact Intergas Heating Ltd).

6.1.2 Thermostatic radiator valves

6.1.1 Expansion vessel

► Flush the central heating system thoroughly. ► Fit the flow and return pipes to the isolation valves. ► All pipes must be fitted unstressed in order to prevent pipes

from ticking.

► Existing connections must not be twisted, in order to avoid

leakages.

The CH system should be equipped with:

► A drain tap in the return pipe immediately below the

appliance. ► A drain tap at the lowest point(s) of the installation. ► A non return valve, if pipes run upwards at a short

distance from the appliance. This avoids the occurrence of

thermosyphon eect during DHW operation mode.

If all radiators have thermostatic radiator valves or valves that can be closed to separate the flow completely from the return, a minimum amount of water circulation must be ensured by the installation of bypass piping, for example (also see §8.5).

The appliance is fitted with a expansion vessel adequate for a system with a water volume not exceeding 100 litres, typically 8 radiators. For larger volume systems, an additional expansion vessel must be fitted. Contact Intergas for advice in these cases.

6 CONNECTION

6.1.3 Floor heating

Floor heating with pump

For eective operation of the DHW supply any undesired circulation through the appliance as a result of a second pump in the CH circuit must be avoided. Connect the floor heating system in a hydraulically neutral manner to the appliance, or equip the CH circuit with an electric shut-o valve or check valve to prevent flow through the appliance when there is no CH request for heat.

Make sure there is a minimum of water circulation; see §8.5.

6.1.4 LT/HT zone system

The central heating system can be divided into two groups, each with a dierent heating temperature, for example a hightemperature zone (HT) with radiators and a low-temperature zone (LT) with underfloor heating system without its own circulation pump. Both zones must have their own room thermostat. LT/HR zone control is activated by the adjustment of a number of parameters.

There are two dierent installation sets available for installing the LT/HT zone system:

► Installation set with two-way valve (item no 093697). ► Installation set with three-way valve (item no 093707).

Operational principle

The valve divides the heat over both zones. Both zones have their own room thermostat and are alternately (time-limited) heated through switching over the valve.

IMPORTANT

► Ensure that the external pump pressure

of the central heating pump in the boiler is taken into consideration during the design phase of the underfloor heating.

► If the radiators in the HT zone have

thermostatic radiator valves, this zone must have a bypass valve.

Page 21

Operational principle

If the room thermostat switches o the boiler because another heat source is heating the room, it is possible that the other rooms will cool down. This can be prevented by dividing the central heating system into two groups. The group with the external heat source (Z2) can be closed o from the main circuit with an electric shut-o valve. Both groups have their own room thermostat.

Note: This ‘external heat source’ control can only be applied if no external boiler must be heated.

Installation manual

► Place the shut-o valve (B) according to the connection

diagram.

6.2.1 DHW circuit resistance graph

► Flush the installation thoroughly to clean (please refer to

current Standard Codes of Practice). ► Fit the cold and hot water pipes into the shut o valve and

the elbow. ► Existing connections must not be twisted, in order to avoid

leakages. Make sure the compression fittings are tightened

thoroughly to prevent leakage.

Comments

► The specific pipeline length with a piping diameter of

12/10mm or 15/13mm is 30 meters and 17.7 meters,

respectively. ► If the boiler is only used for the domestic hot water facility,

the heating function can be switched o. Parameter P001

must then be changed from 0 to 2. In this case, the central

heating system does not need to be connected or filled. ► If the boiler is out of order and disconnected from the

electricity network during the winter months, the water

must be drained to prevent freezing. Disconnect the

domestic hot water connections immediately directly under

the boiler. ► The Xtreme 24 is equipped with a flow restrictor with a

nominal value of 8l/min. The Xtreme 30 and Xtreme 36 do

not have this feature. If desired, this can be ordered from

Intergas as an option.

The Xtreme 36 allows larger volume flows with high water

pressures; to ensure an exhaust temperature of 55°C, the

DHW facility has to be set at 9 l/min.

Connection diagram of boiler with heat pump boiler

Installation:

The combination must be connected according to the connection diagram. The following points are important to guarantee a correct operation of the combination.

Thermostatic switch valve:

The thermostatic switch valve used is a modified valve that meets the specific requirements to which the combination heat pump boiler and Intergas Xtremeare subject. For the correct operation of the combination, the switch valve has a fixed temperature setting. The thermostatic switch valve can be ordered from Intergas (item no: 065127).

6.2.2 Boiler with heat pump boiler

The boiler is suitable for use in combination with a heat pump boiler. If the exhaust temperature of a heat pump boiler is lower than 55°C, the Intergas Xtrememakes sure that the domestic hot water from the heat pump boiler is post-heated under HE conditions.

Operational principle:

The domestic hot water connection of the heat pump boiler is connected to the mix input of the thermostatic switch valve (see the principle diagram). If the DHW temperature of the boiler is higher than the set temperature of the switch valve, the heat pump boiler will be tapped. Because the switch valve is not fully closing, a small amount will also run through the Intergas Xtreme(about 10% of the total flow).

As soon as the exhaust temperature of the heat pump boiler becomes lower than the set temperature of the switch valve, the flow through the Intergas Xtremewill increase. If the flow becomes greater than the domestic hot water threshold of the Intergas Xtreme, the boiler will start domestic hot water demand. When the exhaust temperature of the heat pump boiler has become lower than the set temperature of the switch valve minus 12K, almost the entire domestic hot water flow goes through the Intergas Xtreme. The small leakage flow is now taken from the heat pump boiler. Aer the entire switching of the switch valve, the domestic hot water flow will be limited by the Intergas Xtreme.

Page 24

Domestic hot water inlet pressure:

For a flow volume of 20 litres per minute, the initial pressure must be a minimum of 2.3 bar. The allowed domestic hot water operational pressure for the combination may be a maximum of 6 bar. A safety group (6 bar) must be installed for this purpose.

Maximum flow volume:

If the domestic hot water flow is greater than 20 litres per minute, the Intergas Xtremewill start domestic hot water demand, regardless of the exhaust temperature of the heat pump boiler.

Maximum temperature setting of the heat pump boiler:

The temperature of the heat pump boiler may not be set higher than 60°C.

Position of thermostatic switch valve:

To prevent the thermostatic switch valve being influenced too much by the surrounding air, this valve must be placed in a vertical position and as close as possible to the domestic hot water connection of the boiler (maximum distance of 100mm). This prevents the boiler operating with each tap request.

Influence of water flows:

To prevent the flow being influenced by the Intergas Xtremeduring the switching of the valve, the domestic hot water ‘out’ pipeline of the combination must run straight (see connection diagram [F]).

6.2.3 Boiler with Pre-Heated Solar Boiler)

A connection set and a thermostatic mixing valve are available to order for this purpose.

Comment:

The cold water sensor must be connected to Connector X13 4/5. When combined with a solar energy system, a thermostatic mixing valve, set at 62.5°C, must always be placed aer the boiler.

6.5.4 Connecting outdoor sensor

The boiler has a connection for an Intergas outdoor sensor. The outdoor sensor must be used in combination with an on/o or OpenTherm room thermostat.

In principle, any on/o or OpenTherm room thermostat can be combined with an Intergas outdoor sensor. With an on/ o thermostat, the boiler will adjust the flow temperature according to the set heating line. With an OpenTherm thermostat, this determines the influence on the flow temperature.

► Connect the outdoor sensor to Connector X13 3/4 (also see

§11.1).

For the heating line graph, see §7.6.

X13 X12

► To prevent freezing of the condensation drain piping, the

boiler must be installed in a frost-free area. ► To prevent freezing of the boiler, the boiler is equipped with

frost protection. If the temperature of the water in the heat

exchanger becomes too low, the pump will run (the burner

is switched on if needed) until the temperature of the water

is again at a frost-free level.

Comment

If an on/o room thermostat will be used, secure a frost-hazard area from frost in combination with a frost thermostat. The radiator valve in the frost-sensitive area must be opened.

► In frost-hazard areas (for example, a garage), place a frost

thermostat. ► Connect the frost thermostat together with an on/o room

thermostat or RF thermostat parallel to Connector X13 1/2

(also see §11.1).

6.5.5 Frost protection

CAREFUL

► With the use of an OpenTherm

thermostat, a frost thermostat may not be connected in parallel on Connector X13. In that case, connect the OpenTherm thermostat to Connector X13 and the frost thermostat to Connector X12.

If the (external) frost thermostat is used in the installation and it is connected to the boiler, it is not active when the boiler is switched o.

Comments

► The total pipeline length is:

The sum of the straight pipeline lengths + the sum of the

replacement pipeline lengths of curves/knees are together

25meters. ► If the allowed length of air supply duct pipe and flue pipe

are together 80metres (excluding the length of the combi-

pipe wall terminal or the twin-pipe wall terminal), then the

calculation falls within the allowed pipeline length.

L1 = 1m

L3 = 6,5m

As the resistance of the flue and air supply duct pipes increases, the capacity of the boiler will decrease. The allowed decrease in capacity is a maximum of 5%.

The resistance of the air supply duct and the flue depends on the length and diameter of the piping system and all associated components. For each boiler category, the total allowed pipeline length of the air supply duct and flue is given.

The specification of the pipeline length in meters assumes Ø80 mm piping.

7.4 Clock function

Clock shown (P-on active)

T-on active

The boiler is equipped with a digital clock and oers the possibility to program points in time for both CH operation and DHW operation. To activate the clock program the following parameters have to be set: For CH operation parameter P040 = 1 For DHW operation parameter P087 = 1

► In CH operation 6 points can be programmed to switch from

CH o or CH on.

► In DHW operation 4 points can be programmed to switch

the pre-heat function of the heat exchanger from on to o. Also the pre-heat behavior of an external boiler can be programmed in this mode.

Additionally the following special modes can be chosen:

In CH operation

► P-on (Program on):

The boiler will respond only on CH demands within the chosen time blocks. If the clock program does not contain any valid switching points, the boiler will respond on any CH demand. The actual time is shown on the le display indicating that the clock program is active.

► T-on (Temporary on):

The clock program will be temporary overruled. The boiler will respond to every CH demand until the next "on" switching point. On the le display t-ON will be shown.

► On (Continuous on):

The boiler will respond to every CH demand without any time limit.

► O:

The boiler will not respond to any CH demand.

In DHW operation

► P-on (Program on):

The appliance's DHW comfort function is switched on continuously within the chosen time blocks . In this mode the heat exchanger will be kept on temperature to assure instant delivery of DHW. If the clock program does not contain any valid switching points, the heat exchanger will continuously be kept on temperature.

► On (Continuous on):

The appliance's DHW comfort function is switched on continuously. The heat exchanger will be kept on temperature.

► Eco:

The appliance's DHW comfort function is self learning within the chosen time blocks. The appliance will adapt to the pattern of use of the hot water tap. As a result, the temperature of the heat exchanger will not be maintained during the night or in case of long absence. If the clock program does not contain any valid switching points, the self learning feature is maintained.

► O:

The temperature of the heat exchanger is not maintained, as a result of which the delivery of hot domestic water takes a little time. If there is no need for fast delivery of domestic hot water, DHW comfort function can be switched o.

8.5 Adjusting maximum central heating output

8.6 Adjusting pump capacity

The maximum central heating output is factory-set. If more or less output is needed for the central heating system, the maximum central heating output can be modified with parameter P010. See the table below: Setting central heating output.

The Xtremehas a modulating pump that modulates that modulates based on the central heating output provided. The minimum and maximum capacity of the pump can be adjusted with the parameters P031 and P032. Also see §8.3. The set value of parameter P031 (max. pump setting) is the percentage of the maximum pump capacity and is linked to the set maximum central heating output which is set with parameter P010. The set value of parameter P032 (min. pump setting) is linked to the minimum central heating output. The pump capacity must be set such that the temperature dierence between the supply and return fits with the system.

If the central heating load modulates between the minimum and maximum value, the pump capacity will modulate along proportionately.

8.4 Switching DHW comfort function on and o

It is possible to switch on and o the DHW comfort function from an OpenTherm room thermostat (provided the thermostat supports this function). To do this, the boiler must be set at the ‘eco’ setting and the parameter P074 must be set to 0. The self-learning character of the control is therefore switched o.

If the boiler is connected to another gas type than that for which the boiler has been set by the manufacturer, the gas restriction ring must be replaced. Conversion sets for other gas types are available to order.

Conversion of the restriction ring

► Switch o the boiler and remove the plug from the wall

outlet. ► Close the gas valve. ► Remove the front panel of the boiler. ► Disconnect the connection above the gas valve and turn the

gas mixing pipe to the back. ► Replace the O-ring and the gas restriction ring with the rings

from the conversion set. ► Reconstruct it in reverse order. ► Open the gas valve. ► Check the gas connections before the gas valve for

tightness. ► Put the plug in the wall outlet and switch on the boiler. ► Check the gas connections aer the gas valve for tightness

(during operation). ► Now check the adjustment of the gas/air proportion (see

§8.10).

► Place a sticker indicating the newly set gas type over the

existing sticker near the gas valve. ► Stick the same sticker near the data plate. ► Assemble the front panel of the boiler.

The gas/air control is set in the factory such that the combustion is optimal for the gas type used. The gas type (natural gas or LPG) for which the boiler is adjusted is indicated on the data plate under the boiler. The boiler may not be implemented if the gas used deviates form that which is indicated on the data plate. The boiler may optionally be converted to another gas type using a conversion set. For the correct gas restriction ring, see the table below.

By default, the boiler is set to natural gas G20.

A proper operation of the gas air control can be established by measuring the flue gases directly above the boiler using an analyser probe of a flue gas analyser. The measurement takes place at high and minimum output (for this, see §8.10.1 and

§8.10.2). Any deviation can be corrected solely at minimum output by setting the gas valve anew (see §8.10.3).

IMPORTANT

► Inspection of the gas/air control must be

done with opened casing.

► The measurement must be performed

based on O2; in other words, the flue gas analyser must have an O2 sensor. Conversion of the measured O2 measurement value in the flue gas analyser to a CO2 measurement value is allowed.

► The deviation of the flue gas analyser may

be a maximum of ± 0.3% (based on O2).

► A reliable check and adjustment is only

safeguarded if no extreme vacuum is present in the flue connection opposite the installation location. This also includes a natural draught (wind), for example.

► A deviation at maximum output cannot

be corrected by adjusting the gas valve. In that case, the boiler must be meticulously inspected for gas density and correctness of components used (especially the gas restriction ring and the fan including venturi).

► When replacing components and/or

converting to another gas type, the operation of the gas air control must always be inspected.

8.9 Gas/air control

IMPORTANT

► Work on gas supply pipe components

as well as the adjustment of the gas air control must be performed by an authorised installer.

Page 59

Before measuring the flue gases at minimum output, the measurement at maximum output must be completed. The measured O2(H) or CO2(H) value at maximum output is important for determining the correct value for the check at minimum output. See §8.10.1 for measuring at maximum output.

A. Switch on the boiler at minimum output. To do this, tap

simultaneously the Service button and the Minus button

until the capital letter L appears on the right display.

B. Wait until the readout of the flue gas analyser is stable (at

Page 60

Example (Natural gas G20)

► During maximum output a O2(H) value

of 4.0 % has been measured. In that case the O2(L) value at minimum output must be in-between 4 % (= value O2(H) and

6.05% as stated in the table. When during minimum output a value out of this range is measured the gas-air ratio must be adjusted.

IMPORTANT

► The gas air control is correctly set if the

measured value at minimum output falls within the indicated upper and lower limits. Adjustment of the gas air control is not necessary in this case. The setting at minimum output must be adjusted using the method described in §8.10.3 if the measured value lies outside the indicated limits.

E. If the minimum output measurement falls outside the limits

given in Table 3a or 3b, continue at §8.10.3 to set up the gas valve anew. If the setting is correct, continue to Step F.

F. Mount the front panel and fasten the 2 screws by hand.

Check the CO value at minimum output. The maximum allowed CO measurement value is 160ppm.

G. Switch on the boiler to maximum output. To do this, hold

the Service button and at the same time tap the Plus button 2x until the capital letter H appears on the right

display. Check the CO value at maximum output. The

maximum allowed CO measurement value is 160ppm. H. Switch o the boiler. I. Remove the analyser probe of the flue gas analyser from the

flue gas measurement point and carefully replace the cap

on the adapter above the boiler. J. Switch on the boiler again. K. Check the gas density of the flue gas measurement point.

Page 61

Before the min. output correction is performed, the maximum output and minimum output measurements must be completed. The measured O2(H) or CO2(H) value at maximum output is important for determining the correct value for the setting at minimum output (see §8.10.1 and §8.10.2).

A. Remove the cover screw of the gas valve so that the

adjustment screw is accessible. B. Switch on the boiler at minimum output. To do this, tap

simultaneously the Service button and the Minus button

until the capital letter L appears on the right display.

C. Wait until the readout of the flue gas analyser is stable (at

least 3 minutes). D. Measure the O2(L) or CO2(L) value. E. Using the adjustment screw B, set the correct O2(L) or CO2(L)

value. For the correct O2(L) setting value, see Tables 4a, 4b

or 4c. For the correct CO2(L) setting value, see Tables 5a, 5b

or 5c. F. Reattach the cover screw of the gas valve so that the

adjustment screw is sealed.

► Select the correct table depending on the

applicable gas category:

4a and 5a: natural gas (G20)

4b and 5b: LPG 3P (G31)

► The maximum output measurement

value is decisive for a correct adjustment. This measurement value was noted during the maximum output measurement O2(H) or CO2(H) (see

§8.10.1, Step H).

► Turning the adjustment screw to the

right reduces O2 (and increases CO2); turning to the le increases O2 (and decreases CO2).

► Twist the adjustment screw with small

steps and wait aer each twist until the measurement is stable.

10 MAINTENANCE

► Clean the slats of the heat exchanger from top to bottom with a

brush or vacuum cleaner. ► Clean the underside of the heat exchanger. ► Clean the siphon with water. ► Only clean the underside of the front panel.

CAREFUL

► The integrated insulation panel and burner

seal contain ceramic fibres.

CAREFUL

► Aer work activities, check all flue supply

piping parts for tightness.

► Some components can be hot when the boiler

has just been in operation.

10.1 Disassembly

10.2 Cleaning

The boiler and the system must be inspected annually by an qualified competent gas safe registered engineer and cleanded if necessary. The annual maintenance interval is based on an expected operation time of approx. 1,500 heating hours/year (average domestic use), via Comfort Touch dashboard and installerd app. If not monitored by Comfort Touch then the boiler must be serviced annually.

► Switch o the appliance and isolate the power supply at the fuse

spur, make safe the appliance before continuing (Ref TB118). ► Close the gas valve. ► Remove the front panel of the boiler by unscrewing the two

screws (1) and then removing the panel up and forward (2). ► Wait until the boiler has cooled down. This can be done by

opening a domestic hot water tap. ► Turn the expansion vessel aside. ► Disconnect the connector of the fan. ► Disconnect the connection under the gas valve. ► Unscrew the shoulder bolts (socket) of the front cover and

remove the cover forward with the gas valve and fan (pay

attention that the burner, insulation panel, gas valve, gas piping

and the fan do not become damaged). Lay the removed front

cover with the foot supports horizontal on a smooth surface. ► The burner and the integrated insulation panel do not require

maintenance (do not need to be cleaned). Therefore, never use a

brush or compressed air to clean these components so that the

development of dust is avoided. ► Remove the siphon cup by turning it counter-clockwise and then

removing it downwards.

COMMENT

► The expansion vessel must be inspected and

tested at each annual service and if required re-pressure to 0.75 bar.

Page 69

► Check whether there is a thin layer of ceramic grease

between the flange of the shoulder bolt and the front panel.

If there is insuicient grease present, extra must be applied:

► Check whether the gasket around the front panel is

correctly placed. Place the front panel on the heat

exchanger and attach it with the special shoulder bolts

(socket). Tighten the shoulder bolts (1 to 11) by hand,

working diagonally. For the order of tightening, see the

picture. ► Verify the shoulder bolts according to the same order with a

torque spanner at 10-12Nm. ► Tighten the burner bolts diagonally by hand. ► Check the gasket and fit the gas connection under the gas

valve. ► Install the connector on the fan. ► Open the gas valve and check the gas connections under

the gas valve for leakage. ► Check the water supply piping for leakage. ► Fill the siphon cup to just over half full. ► Replace the siphon cup by sliding it over the siphon spout

and then turning it clockwise until it is secure. Check

whether the siphon spout is sticking into the water and

check whether the siphon cup is firmly in place. ► Turn the expansion vessel back to its original position. Make

sure the vessel is secured by the lip on the cable cover. ► Turn the power supply on at the fuse spur. ► Switch on the boiler. ► Check the front cover, the connection of the fan on the front

cover, and the flue components for leakage. ► Check the gas/air control (see §8.9 and §8.10) and check

the gas connection on the gas valve for tightness. ► Install the casing and tighten the two screws at the le and

right under the boiler. ► Check the domestic hot water facility for correct operation.

10.3 Installation

IMPORTANT

► Replace the front plate O-ring every 3

years. Art.no: 877927 — Xtreme 24/30

620274 — Xtreme 36

► Check and replace any other gaskets.

Also check the correct positioning.

every annual service

Maintenance must be carried out at regularly

1 Isolate the boiler from the fuse spur and make safe (ref TB118) check

the correct 3amp fuse fitted.

2 Carry out inspection of boiler for dust and dirt and clean where

necessary.

3 Visually inspect the front plate and heat exchange for signs of

damage. If damage is evident proceed to column 2.

4 Check the gas inlet pressure on HIGH rate (DHW mode).

5 Check combustion by measuring CO, CO2. If the values are outside the

tolerances then proceed to a full service in column 2.

6 Close the gas isolation valve.

7 Isolate flow and return valves and drain boiler via the drain o on

the return. Check the charge in the expansion vessel. Recharge if necessary.

8 Remove the front plate and clean the inside of the heat exchanger.
