Installation and operation manual

3 General safety precautions

▪ ONLY operate the gas boiler if a sufficient supply of combustion

air is ensured. In case of a concentric air/flue gas system dimensioned according to the specifications of this manual, this is fulfilled automatically and there are no other conditions for the equipment installation room. This method of operation applies exclusively.

▪ Store flammable fluids and materials at least 1meter away from

the gas boiler.

Do NOT install the unit in the following places:

▪ In potentially explosive atmospheres.

▪ In places where there is machinery that emits electromagnetic

waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.

▪ In places where there is a risk of fire due to the leakage of

flammable gases (example: thinner or gasoline), carbon fibre, ignitable dust.

▪ In places where corrosive gas (example: sulphurous acid gas) is

produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.

▪ In bathrooms.

▪ In places where frost is possible. The ambient temperature around

the gas boiler should be >5°C.

3.2.3 Water

If applicable. See the installation manual or installer reference guide of your application for more information.

NOTICE

Make sure water quality complies with EU directive 98/83EC.

Avoid damages caused by deposits and corrosion. To prevent corrosion products and deposits, observe the applicable regulations of technology.

Measures for desalination, softening or hardness stabilization are necessary if the filling and top-up water have a high total hardness (>3 mmol/l–sum of the calcium and magnesium concentrations, calculated as calcium carbonate).

Using filling water and top-up water which does NOT meet the stated quality requirements can cause a considerably reduced service life of the equipment. The responsibility for this is entirely that of the user.

WARNING

▪ ONLY use copper wires.

▪ Make sure the field wiring complies with the applicable

legislation.

▪ All field wiring MUST be performed in accordance with

the wiring diagram supplied with the product.

▪ NEVER squeeze bundled cables and make sure they

do NOT come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.

▪ Make sure to install earth wiring. Do NOT earth the unit

to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.

▪ Make sure to use a dedicated power circuit. NEVER

use a power supply shared by another appliance.

▪ Make sure to install the required fuses or circuit

breakers.

▪ Make sure to install an earth leakage protector. Failure

to do so may cause electrical shock or fire.

▪ When installing the earth leakage protector, make sure

it is compatible with the inverter (resistant to high frequency electric noise) to avoid unnecessary opening of the earth leakage protector.

CAUTION

▪ When connecting the power supply: connect the earth

cable first, before making the current-carrying connections.

▪ When disconnecting the power supply: disconnect the

current-carrying cables first, before separating the earth connection.

▪ The length of the conductors between the power supply

stress relief and the terminal block itself must be as such that the current-carrying wires are tautened before the earth wire is in case the power supply is pulled loose from the stress relief.

NOTICE

Precautions when laying power wiring:

3.2.4 Electrical

DANGER: RISK OF ELECTROCUTION

▪ Turn OFF all power supply before removing the switch

box cover, connecting electrical wiring or touching electrical parts.

▪ Disconnect the power supply for more than 10minutes,

and measure the voltage at the terminals of main circuit capacitors or electrical components before servicing. The voltage MUST be less than 50 V DC before you can touch electrical components. For the location of the terminals, see the wiring diagram.

▪ Do NOT touch electrical components with wet hands.

▪ Do NOT leave the unit unattended when the service

cover is removed.

WARNING

If NOT factory installed, a main switch or other means for disconnection, having a contact separation in all poles providing full disconnection under overvoltage categoryIII condition, MUST be installed in the fixed wiring.

Installation and operation manual

▪ Do NOT connect wiring of different thicknesses to the

power terminal block (slack in the power wiring may cause abnormal heat).

▪ When connecting wiring which is the same thickness,

do as shown in the figure above.

▪ For wiring, use the designated power wire and connect

firmly, then secure to prevent outside pressure being exerted on the terminal board.

▪ Use an appropriate screwdriver for tightening the

terminal screws. A screwdriver with a small head will damage the head and make proper tightening impossible.

▪ Over-tightening the terminal screws may break them.

Install power cables at least 1m away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 1m may not be sufficient.

INFORMATION

The boiler is provided with a Ø25mm flexible pipe on the condensate trap.

Prerequisite: The boiler MUST be opened before installing the condensate trap.

1 Fit the flexible tube (accessory) to the condensate trap outlet. 2 Fill the condensate trap with water. 3 Slide the condensate trap as far as possible upwards onto the

condensate drain connector below the gas boiler.

4 Connect the flexible tube (where applicable with the overflow

pipe from the pressure relief valve) to the drain via an open connection.

3 Lift the boiler. One person lifts the gas boiler on the left side (left

hand on the top and right hand on the bottom) and another person lifts the gas boiler on the right side (left hand on the bottom and right hand on the top).

4 Tilt the top of the unit at the position of the wall bracket and

slide the boiler downwards to fix the boiler bracket onto the wall bracket.

WARNING

▪ ALWAYS fill the condensate trap with water and place

it on the boiler before powering up the boiler. See illustration below.

▪ NOT placing or filling up the condensate trap may

cause flue gases to come into the installation room and can lead to dangerous situations!

▪ In order to place the condensate trap, the front cover

MUST be pulled forward or removed entirely.

5 Make sure the gas boiler is fixed properly to the wall.

NOTICE

It is recommended that any external condensate pipe is insulated and increased to Ø32mm in order to prevent the condensate from freezing.

6.4 Condensate pipe work

INFORMATION

The condensate discharge system MUST be made of plastic, no other materials may be used. The discharge duct MUST have a minimum gradient of 5~20 mm/m. Condensate discharge via the gutter is NOT allowed due to risk of frost and the possible damage to the materials.

6.4.1 Internal connections

If possible, the condensate drain pipe should be routed and terminated so that the condensate drains away from the boiler under gravity to a suitable internal foul water discharge point such as an internal soil and vent stack. A suitable permanent connection to the foul waste pipe should be used.

a Condensate discharge from boiler b Soil and vent stack c Minimum 450mm and up to 3 storeys

If the first option is NOT possible, an internal kitchen or bathroom waste pipe, washing machine pipe can be used. Make sure that the condensate drain pipe is connected downstream of the waste trap.

The pump outlet pipe should discharge to a suitable internal foul water discharge point such as an internal soil and vent stack, internal kitchen, bathroom waste pipe, or washing machine waste pipe. A suitable permanent connection to the foul waste pipe should be used.

6.4.2 External connections

If an externally condensate drainage pipe is used, following measures should be made to prevent freezing:

▪ The pipe should be run internally as far as possible before going

to the outside. The pipe diameter should be increased to a minimum inner diameter of 30 mm (typically outer diameter of 32mm) before it goes through the wall.

▪ The external run should be kept as short as possible, taking the

most vertical route possible to the discharge point. Take into account that there are no horizontal sections in which condensate might collect.

▪ The external pipe should be insulated. Use a suitable waterproof

and weather proof insulation ("ClassO" pipe insulation is suitable for this purpose).

▪ The use of fittings and elbows should be kept to a minimum. Any

internal burrs should be removed so that the internal pipe section is as smooth as possible.

3 Connect the hot water connection (Ø15mm). 4 Connect the main cold water connection (Ø15mm).

DANGER: RISK OF BURNING/SCALDING

In case of high leaving water setpoints for space heating (either a high fixed setpoint or a high weather-dependent setpoint at low ambient temperatures), the heat exchanger of the boiler can be heated up to temperatures higher than 70°C.

In case of a tapping demand, it is possible that a small volume of water tapping (<0.3l) has a temperature higher than 70°C. To prevent scalding, it is recommended to install a thermostatic valve according to the following schematic:

a=boiler, b=domestic hot water from the boiler, c=cold water inlet, d=shower, e=thermostatic valve (field supply)

To connect the water piping for domestic hot water (applicable for Switzerland)

For Switzerland, domestic hot water should be made by a domestic hot water tank. The domestic hot water tank must be installed with a 3-way valve to the space heating piping. See the manual of the domestic hot water tank for more details.

Not applicable for Switzerland

To connect the water piping for space heating

NOTICE

To prevent leakages, do NOT rotate existing connections.

NOTICE

Mount the pipes without tension to avoid ticking sounds from the pipes.

1 Rinse the space heating installation carefully. 2 Connect the space heating outlet (a) and space heating inlet (b)

to their connections as indicated in the following illustration:

Fit the space heating installation with the following parts:

▪ A filling/draining tap in the space heating inlet, immediately

underneath the unit.

▪ A draining tap at the lowest point of the installation.

▪ An overflow valve of 3bar in the input pipe at a distance of no

more than 500 mm from the unit. Between the unit and the overflow valve there may be no valve or constriction.

▪ An expansion vessel in the space heating inlet (in the B-pack or in

the installation).
