1. OPERATING INSTRUCTIONS

1.1 Introduction

Dear Customer, Thank you for choosing Maxima 35 C, a FERROLI wall-mounted boiler of the latest generation,

featuring advanced design and cutting-edge technology. Maxima 35 C is a high-efficiency condensing pre-mix appliance for heating and hot water production

with extremely low emissions, running on natural gas or LPG. The boiler consists of an aluminium laminar heat exchanger providing effective condensation of the

water vapour contained in the flue gases, permitting extremely high efficiency. Above the heat exchanger, in the boiler, there is a pre-mix burner, with a large ceramic surface,

equipped with electronic ignition and ionization flame control, which achieves extremely low emissions while ensuring high reliability and long life operation.

The boiler is totally room sealed from the installation room: the air needed for combustion is drawn from outside. The boiler also includes a modulating speed fan, modulating gas valve, pumps, expansion vessel, flow meter, safety valve, flow sensor, temperature sensors, a safety thermostat and a low pressure sensor.

Thanks to the twin microprocessor control and adjustment system with advanced self-diagnosis, unit operation is for the most part automatic. The power for heating is automatically governed by the control system according to the indoor and outdoor characteristics (with an optional outdoor sensor installed), the characteristics of the building and of its location. The power for hot water is automatically and continually governed to ensure a fast delivery and comfort under all operating conditions.

The user only has to set the temperature desired inside the home (by means of an optional room thermostat or remote control, which is required under the building regulations 2002) or regulate the temperature of the system, and set the desired outlet temperature for the hot water. The adjustment and control system will provide optimum operation throughout the year.

The display continuously provides information on the unit’s operating status and it is easily possible to obtain additional information on the sensor temperatures, set-points, etc. or configure them. Any operating problems associated with the boiler or system is immediately signalled by the display and, if possible, corrected automatically.

2.2 Boiler location

The unit’s combustion circuit is sealed off from the installation room. The installation room must be sufficiently well ventilated to prevent any dangerous conditions from forming in the event of even slight gas leakage. This safety standard is required by the EEC Directive no. 90/396 for all gas units, including those with a so-called sealed chamber.

Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The room must be dry and not subject to freezing.

The boiler is design to be installed on a solid wall. The wall fixing must ensure a stable and effective support for the appliance, using the bracket and fixings supplied.

If the unit is enclosed in cupboard or mounted alongside, there must be space for normal maintenance work. Fig. 2 and tab. 1 give the minimum clearances to leave around the unit.

Page 11

Maxima 35 C

Make Up Water

Provision must be made for replacing water lost from the sealed system. Reference should be made to BS6798, for methods of filling and making up sealed systems. There must be no direct connection between the boiler's central heating system and the mains water supply. The use of mains water to charge and pressurise the system directly, is conditional upon the Local Water Byelaws. Again any such connection must be disconnected after use. The supplied temporary filling loop is shown in fig.

4. Ensure the filling point is on the return pipe to the boiler.

Attention - is drawn to the Model Water Byelaws.

Fittings manufactured from duplex (alpha-beta) brass are not acceptable for underground use and certain water undertakings will not accept their use above ground.

Ensure all pipework is adequately supported

NOTE: An automatic bypass must be fitted as far as possible from the boiler if thermostatic radiator valves are fitted thoughout.

2.3 Boiler water connections

The heating capacity of the unit should be previously established by calculating the building’s heat requirement according to current regulations. For good operation and long life of the boiler, the plumbing system must be well proportioned and always complete with all those accessories that guarantee regular operation and running, room thermostat, trv’s and automatic bypass.

If the delivery and return pipes follow a path where air pockets could form in certain places, it is esential to install vent valves at these points. Also, install a type “A” drain cock device at the lowest point in the system to allow its complete draining.

The temperature differential between the flow manifold and the return to the boiler should not exceed 20° C.

A minimum flow of 6 litres/min is requied through the heat exchanger, it is therefore essential to fit a automatic bypass a min of 3 meters away from the appliance, calobrated on site.

Do not use the water system pipes to earth electrical appliances.

Before installation, carefully flush all the pipes of the heating system to remove residues or impurities that could affect the unit’s good working (BS 7593 Building regs Doc L).

Make the connections to the appliance as shown in fig. 5.

Key

1 System flow (22 mm with isolation valve fitted) 2 DHW outlet (15 mm with isolation valve fitted) 3 Gas inlet (22 mm with isolation valve fitted) 4 Cold main inlet (15 mm with isolation valve fitted) 5 System return - 22 mm with isolation valve fitted (c/w filter) 6 System drain 7 Condense outlet

It is essential to install the isolation valves supplied between the boiler and heating system, allowing the boiler to be isolated from the system if necessary.

The safety valve outlet must be connected to a 15 m pipe to allow system water out onto the ground in the event of over-pressure in the heating circuit. If this is not done, and the drain valve trips and floods the room, the boiler manufacturer is not to be held responsible. The outlet should face back against the outer brickwork or building face to prevent harm or injury from hot

water discharging in the evet of an over-pressuried system. Make the boiler connection in such a way that its internal pipes are free of stress. If a check valve is installed on the tap water circuit (where applicable), it is necessary to mount a safety valve between the boiler and this circuit (check valve minimum 3 meters from boiler).

accordance with the manufacturers instructions.

Page 14

Maxima 35 C

2.4 Connection to the gas system

If necessary the local Gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas.

An existing service pipe must not be used whitout prior consultation with the local Gas supplier. A gas meter can only be connected by the Local Gas supplier, or by a Local Gas suppliers

Contractor. Installation pipes should be fitted in accordance with BS6891. Appliance inlet working pressure

must be 20 mbar MINIMUM, for NG and 37 mbar minimum for pro-

pane. Do not use pipes of a smaller size than the combination boiler inlet gas isolation valve (22 mm).

The complete installation must be tested for gas soundness and purged as described in BS6891. All pipework must be adquately supported. An isolating gas valve is provided and should be fitted on the boiler gas inlet. Please wait 10 minutes when ligthing from cold before checking the gas rate. Gas pressures should be checked after the boiler has operated for 10 minutes to ensure

thermal equilibrium. The appliance has no facility to check burner pressures, a combuston test should be carried out instead,

see page 28 (combuston analyser testing).

The connecting kits shown in fig. 6 are supplied as standard.

2.5 Electrical Connections

The unit must be installed in conformity with current national and local regulations.

Connection to the electrical grid

The boiler must be connected to a single-phase, 230 Volt-50 Hz electric line.

The unit’s electrical safety is only guaranteed when correctly connected to an efficient earthing

system executed according to current safety standards. Have the efficiency and suitability of

the earthing system checked by professionally qualified personnel. The manufacturer is not

responsible for any damage caused by failure to earth the system. Also make sure that the

electrical system is adequate for the maximum power absorbed by the unit, as specified on

the boiler dataplate, in particular ensuring that the section of the system’s cables is suitable

for the power absorbed by the unit. The boiler is prewired and provided with a cable for connection to the electricity line. The connections to the supply must be made with a permanent connection and equipped with a double pole switch whose contacts have a minimum opening of at least 3 mm, and fused at max. 3A between the boiler and the line. It is important to respect the polarities (LIVE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to the electrical supply.

The user must never change the unit’s power cable. If the cable gets damaged, switch off the

unit and have it changed solely by professionally qualified personnel. If changing the electric

power cable, use solely “HAR H05 VV-F” 3x0.75 mm2 cable with a maximum outside diameter

of 8 mm.

2.6 Flue system

The unit is “type C” with a sealed chamber and forced draught, the air inlet and flue outlet must be connected to one of the following flue systems. With the aid of the tables and methods of calculation indicated, before commencing installation, it is first necessary to check that the flue system does not exceed the maximum permissible length. The current standards and local regulations must be observed.

It should be notes that only Ferroli flue system and accessories should be used on this appliance, as per BS 5440 2000 and C.E. test certification.

Outside temperature compensation

When the (optional) external sensor kit is fitted to the appliance, the display will show outside temperature in bottom right hand side.

By pressing the “ MODE” key once, the maximum boiler flow temperature curve can be set (option of between 0 to 10)

1 = Maximum flow temperature of appliance 30 °C 10 = Maximum flow temperature of appliance 85 °C (0 = O.T.C. = OFF) By pressing the “MODE” key second time, the curve start point is displayed (default 30 °C). To alter the above use the +/- key’s a recommended start point of between 20 to 30 °C and flow temp

of 85 °C is usually required in the U.K. (curve 9 or 10). In O.T.C. mode the temperature of the heating system is controlled according to the external climate

conditions, this will guarantee a high degree of comfort and energy saving all year round. When the external temperature falls, the CH flow temp is increased according to the compensation curve

set up (see chart below) correct of the outside sensor is important - see fig. 8a and 8b.

is compared to the loss of one metre of flue (defined as equal to 1). For example, a bend at 90° of Ø80 in flue run has an equivalent loss of 2.5 linear metres, i.e. it has a loss equal to that of 2.5 metres of flue length.

2. After completely designing the layout of

the system, add up the losses in equivalent metres, depending on the installation position, of all the components and accessories in the system.

3. Check that the total calculated loss is less

than or equal to 55 equivalent metres, i.e. the maximum permissible for this model of boiler.

For complete flue options please contact FERROLI or check our comprensive flue manual.

Maxima 35 C

Connection to collective ﬂ ues or single ﬂ ues with natural draught

If you are then going to connect the Maxima 35 C boiler to a collective flue or a single flue with natural draught, the flue must be expressly designed by professionally qualified technical personnel in conformity with the standards and rules in force.

In particular, flues must have the following characteristics:

• Be sized according to the method of calculation stated in the standard

• Be airtight to the products of combustion, resistant to the fumes and heat and waterproof for the condensate

• Have a circular or square cross-section (some hydraulically equivalent sections are permissible), with a vertical progression and with no constrictions

• Have the ducts conveying the hot fumes adequately distanced or isolated from combustible materials

• Be connected to just one unit per floor, for at most 6 units in all (8 if there is a compensation duct or opening)

• Have no mechanical suction devices in the main ducts

• Be at a lower pressure, all along their length, under conditions of stationary operation

• Have at their base a collection chamber for solid materials or condensation of at least 0.5 m, equipped with a metal door with an airtight closure.

fig. 12

0,5 lt.

2.7 Condensate outlet connection

The boiler is equipped with an internal air-trap to drain off the condensate. Fit the inspection bowl A and the hose B, pushing it out for approximately 3 cm.

Fill the air-trap with approximately 0.5 l. of water and connect the hose to the waste system or soakaway.

Page 24

Maxima 35 C

Condensate discharge

Where possible the condensate should discharge into an internal soil pipe or waste system. The minimum pipe diameter required is 22 mm, a trap has already been fitted to the appliance with a flexible tail to facilitate the connection to the condensate discharge pipe.

The pipe should be a solvent weld plastic, not copper, as the condensate has a ph value of 4 (slightly acidic).

Where it is not possible to terminate internally, the condensate discharge pipe may be run outside (see below drawing).

Any external run is subjet to freezing, in severe weather conditions. To avoid this the pipework should be installed to dispose of the condensate quickly, with as much as possible run internally, before passing through the wall.

Pipework external to the building should be increased in diameter to 32 or 40 mm solvent weld. It should be run to a external drain or soakaway, with a maximum lenth of 3 metres.

If a soakaway (condensate absorption point) is used, it should be constructs as shown below.

3. SERVICE AND MAINTENANCE

3.1 Adjustments

All adjustment and conversion operations must be carried out by Qualified Personnel such as the Ferroli Technical Service.

FERROLI declines any responsibility for damage or physical injury caused by unqualified and unauthorized persons tampering with the device.

Gas supply conversion

The unit can function with either Natural Gas or LPG (commercial propane) and is factory-set for use with one of the two gases, as clearly shown on the packing and on the unit’s dataplate. Whenever a different gas to that for which the unit is preset has to be used, a conversion kit will be required, proceeding as follows:

1 Remove the casing. 2 Open the combustion chamber. 3 Unscrew the gas coupling A on the air/gas ven-

turi.

4 Replace the injector in the mixer with the one

contained in the conversion kit.

5 Refit the coupling A and check the connection is

gas tight.

6 Apply the sticker, contained in the conversion kit,

near the dataplate.

7 Fit the combustion chamber and casing back on. 8 Check inlet working pressure. 9 Set CO2 mixture as detailed (page 28).

3.2 Initial start-up

Commissioning must be performed by Qualified Personnel. Checks to be made at initial start up, and after all maintenance operations that involved disconnecting from the system or an intervention of a safety device.

Before lighting the boiler:

• Open any isolation valves between the boiler and the system.

• Check the tightness of the gas system, proceeding with caution and use gas leak detection fluid to detect any leaks an connections.

• Fill the water system and make sure that all air contained in the boiler and the system has been vented by opening the air vent valve on the boiler and any vent valves on the system.

• Make sure there are no water leaks in the system, hot water circuits, connections or boiler.

• Make sure the electrical system is properly connected.

Page 26

Maxima 35 C

• Make sure that the unit is connected to a good earthing system.

• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler.

• Vent and spin pumps.

• Ensure flue system is correctly fitted, including terminal locations.

Ignition

• Open the gas valve upstream of the boiler.

• Purge the air from the installation pipework to the appliance.

• Swith on boiler fused spur.

• Press the ON/OFF key (see fig.1).

• The boiler is now ready to function automatically whenever hot water is drawn or the room thermostat and clock calls for heating.

In case of an electrical power failure while the boiler is working, the burner will go out. When power returns, the boiler will run the self-test cycle again, after which the burner will automatically re-ignite (if there is still demand for heat).

Checks during operation

• Check for water leaks.

• Check the efficiency of the flue and air ducts while the boiler is operating.

• Check that the water is circulating properly between the boiler and the systems.

• Make sure that the gas valve modulates correctly in both the heating and hot water production phases.

• Check for correct ignition of the boiler by performing various tests, turning it on and off with the room thermostat or remote control.

• Make sure that the fuel consumption indicated on the gas meter corresponds to that given in the technical data table in chap. 4.

• Check there is the right flow rate of hot water with the ∆t stated in the chart. The measurement should be made with specific instruments and as close as possible to the boiler, also consider the heat lost from the pipes.

• Make sure that with no call for heating the burner correctly ignites on opening a hot water tap. Check that during heating operation, on opening a hot water tap, the heating circulator stops and there is a production of hot water.

3.3 Maintenance

The following operations are strictly reserved for Qualified Personnel, such as corgi registered engineers or Ferroli personeer.

Seasonal inspection of the boiler and ﬂ ue

It is advisable to carry out the following checks at least once a year:

• The control and safety devices (gas valve, flow meter, thermostats, etc.) must function correctly.

• The flue terminal end piece and ducts must be free of obstructions and leaks.

• The gas and water systems must be sound.

• The burner and exchanger must be clean.

• The electrodes must be free of scale and properly positioned.

• The water pressure in the cold water system must be approx 1 bar; otherwise, bring it to that value.

• The expansion vessel must be filled to 1 bar cold with zero system pressur.

• The gas flow and pressure must correspond to that given in the respective tables.

• The circulating pumps must be vented and free of debris.

• The returned filter cleaned.

Page 27

Maxima 35 C

Opening the casing

To open the boiler casing, you need to follow the sequence given below and the instructions of fig. 15.

1 Using a screwdriver, fully unscrew

the 2 screws “A ”

2 Open by pulling the panel “B ” 3 Lift and take off the panel “B ”

fig. 15

Cleaning the boiler and burner

The body and burner must not be cleaned with chemical products or wire brushes. Special care must be taken over all the sealing systems pertaining to the sealed chamber (gaskets, cable clamps, etc.). In addition, it is necessary to pay attention after performing all these operations to check and carry out all the phases of ignition and thermostat operation, the gas valve and circulation pump.

After these checks, make sure there are no gas leaks.

Combustion analyser testing

It is possible to analyse the combustion through the air and flue sampling points shown in fig.

16. To make the measurement, it is necessary to:

1) Open the flue sampling point

3) Insert the probe;

4) Press the “+” and “-” keys for 5 seconds to

turn on TEST mode;

6) Wait 10 minutes for the boiler to stabilize

7) Take the measurement.

CO2 reading should be 8,7 to 9,0 % CO2. Propane CO2 should be 9,5 to10%.
