Postioning

Remove all the packaging and check that the appliance is

in perfect conditions. In case of visible damage, do not

connect the appliance and notify the sales point immedia-

tely.

Remove the PVC protection from the panels.

Dispose of packaging according to regulations. Generally

material is divided according to composition and should

be delivered to the waste disposal service.

Maintain a distance of 5 cm between the back (chimney)

of the appliance and the wall. There are no particular pre-

scriptions regarding side distances from other appliances

or walls, however it is advisable to leave enough space in

case of maintenance and/or repairs. It is advisable to fit a

suitable heat insulation if the appliance is in direct contact

with inflammable walls.

The appliance must stand level. Small differences in level

can be eliminated by screwing or unscrewing the adjusta-

ble feet: A significantly uneven or sloping stance can af-

fect the operation of the appliance adversely.

Installation

Warning! : Only qualified technicians must perform

the installation, maintenance and test of the appliance.

Warning! : Before connecting any parts of the

appliance to supplies, make sure that the latter is equi-

valent the requirements stated in the technical data

plate, if the appliance has been designed for these

supplies.

Connection to waterworks

Water inlet pressure must be between 50 and 300 kPa,

otherwise install a pressure regulator on the line before the

appliance.

Install a cut-off valve for each supply on the line before the

appliance.

Water connections to 10 mm are fitted in the lower part on

the left-hand side of the appliance.

Make connections according to regulations currently in

force.

Gas connection procedures

The choice of the gas piping depends on the diameter re-

quired for the type of gas, appliance and installation and

should be performed in conformity with current regula-

tions.

The gas feed plant can either be fixed or be disconnec-

ted; if flexible pipes are employed they must be made

from stainless material and not be affected by corrosion.

If sealing materials are used for connections, they must be

certified and approved for the purpose.

The gas fitting is located on the lower right side of the ap-

pliance

Once the appliance has been connected, carry out a

leakage test on all the fittings connecting the appliance to

the plant. It is advisable to use a leakage spray, otherwise

treat the parts with a foam that does not produce corro-

sion; no bubbles should develop. Carry out the leakage

test also on the rapid cut-off valve.

Warning! : Flames are strictly prohibited for

leakage tests!

Checking the operation of the gas sy-

stem

Check that the appliance has been prepared (category

and type of gas) equivalent to the family of gas available

on site. If not, it is necessary to convert the appliance to

whatever is available. See the paragraph “Conversion to

other types of gas”.

The appliance must be used with the correct injectors for its

thermal power rating (See table page 8 in the “Technical

data”).

The operation of the appliance with its heating capacity

depends on the inlet pressure and the calorific power of

the gas.

The pressure range (inlet pressure) within which the ap-

pliance is allowed to operated is stated in table page 7

“Inlet pressure” of the paragraph “Technical Data”. The

appliance shall not be operated out of the given pressure

range. If pressure should differ from the figures stated in

table page 7, advise the gas board or the company which

has installed the system.

The lower calorific value of the gas can be checked with

the supply company or agency, and should comply with

the information given in table page 8 “Gas data” in the

“Technical data” heading.

Control of the gas inlet pressure

The feed pressure is measured using a liquid pressure

gauge ( e.g. a U-shaped pressure gauge, minimum defi-

nition 0.1 mbar). The supply pressure can be measured

directly at the inlet pressure intake on the gas feed pipe.

The inlet pressure intake can be reached by opening the

lower front panel once the two side screws have been re-

moved. (See figure “Measuring the inlet pressure ”).

Before connecting the manometer, the screw of the pres-

sure port must be loosened.

Connect the U-shaped pressure gauge while the applian-

ce is operating to measure pressure.

The pressure reading on the gauge should be in the ad-

mitted pressure range stated in table page 8 “Inlet pres-

sures” of paragraph “Technical data”.

If pressure figures should not be correct, apply to the gas

board or the company which has installed the system.

Having read the pressure, re-tighten the screw carefully.

Warning! The sealed adjuster screws on the

gas solenoid valve must not be tampered with,

otherwise any guarantee rights shall be forfeited im-

mediately.
