2. INSTALLATION
2.a Regulations (Fig.3)
The use of gas devices is controlled by precise regulations. It is
essential to observe regulations in force.
Installation of liquid petroleum gas (L.P.G) must comply with all the
distributor's requirements and those of the regulations.
2.b Wall mounting (Fig.4)
Warning
Do not install this device in an area that contains dust, greasy
vapour and/or corrosive elements.
- The device must be installed on a suitable wall surface in proxi-
mity to a fume disposal flue.
- It is vital to leave the minimal distances around the device as
shown in fig 3 to allow for maintenance operations to take pla-
ce.
Location
- The water heater must not be tightly placed in an enclosure or
slot, it should have an adequate flow of air around it (fig. 4)
- The water heater must not be placed above a kitchen or other
cooking devices that might deposit grease vapour on its exterior
leading to corrosion
- surfaces that sensitive to heat (e.g. wood) must be protected
using appropriate insulation.
- Fig. 4 displays the dimensions necessary for wall mounting

2.c Room ventilation
The installation of the water heater must comply with regulations in
force including any updates. See paragraph 2.a
Warning: This device can only be installed in venues that are per-
manently ventilated according to regulation in force.

Air circulation
It is vital that areas where gas devices are installed (type B) have
access to the amount of air necessary for the regular combustion
of gas as well as the ventilation of the venue.
- It is prohibited to use an extractor fan, fireplaces and other simi-
lar devices at the same time as the water heater
- The area where the water heater is installed must have a regu-
lar flow of air for ventilation.
Air flow
The flow of air must occur by the following means:
- Permanent openings in the wall that lead outdoors;
- Single or collective ventilation ducts.
The air used for ventilation must be taken directly from an outside
location, that is far from sources of pollution.
Indirect ventilation from adjacent areas are permitted with the fol-
lowing limitations:
- the adjacent area is equipped with direct ventilation;
- the devices within the area to ventilate are connected to a wa-
ste duct;
- the adjacent area does not contain a bedroom and is not a com-
mon area;
- the adjacent area is not a fire hazard such as a storage area for
flammable materials, garage etc.
- the adjacent area is not lower than the area to ventilate as this
might lead to an opposing draught (this can be caused by other
devices that operate on the basis of combustion, a fireplace or
any suction device that have not been given an adequate air
supply);
- The air flow from the adjacent area occurs freely through per-
manent openings.
2.d Gas Connection
See paragraph 2.a
Determine the pipe diameter according to current regulations.
Before installing the device blow in the gas pipe to eliminate any
residue from its manufacturing. Connect the water heater to the
internal system's gas pipes and place a tap above the device for
the halting and release of gas.
The water heaters that are powered by tanks of L.P.G. gas with
regulation and interception devices, must be connected correctly
so to guarantee the safety of persons and the surrounding area.
Follow all related regulations.
When initially installing the device qualified persons must perform
the following tests:
- Check that the internal and external parts of the gas supplying
device are sealed;
- check that the gas quantity supplied is equal to that required by
the device;
- check that the device receives the type of gas it is manufactured
to process;
- check that the gas supply pressure does not go beyond the
maximum pressure values displayed on the information plate;
- check that the gas supply system supplies the necessary
amount of gas to the device and that it is equipped with all the
necessary safety devices prescribed by current regulations.
If the user is absent for a lengthy period, turn off the main gas
supply tap.
Do not obstruct the area's ventilation openings where the device is
installed to avoid dangers such as the build up of toxic and explo-
sive substances.
Do not utilize gas tubes to earth electrical devices.
