The appliance gas supply pressure, both static and dynamic, must comply with the values in the Table, with a tolerance of ± 15%.
3.3.5
Vertical pipes and condensate
▶
Vertical gas pipes must be fitted with siphon and dis-
charge of the condensate that may form inside the
pipe.
▶
If needed, insulate the piping.
3.3.6
LPG pressure reducers
With LPG the following must be installed:
▶
A first stage pressure reducer, close to the liquid gas
tank.
▶
A second stage pressure reducer, close to the appli-
ance.
Pressure reducers must always be installed outside
the building.

COMBUSTION PRODUCTS EXHAUST
Compliance with standards
The appliance is approved for connection to a
combustion products exhaust duct for the types
shown in Table 1.1
p. 9.

Installation types
The flue gas exhaust/combustion air intake of the
Supercromo gas-fired convectors can be realised in one of
the following ways:
▶
With coaxial pipes with outlet on the installation
wall (maximum pipe length: 1 metre) (see Figure
p. 12).
▶
With coaxial pipes with 90° outlet (max pipe length: 1
metre) (see Figure 3.3
p. 13). In this case, it is neces-
sary to use the 90° casing for coaxial pipes, available as
OCFF004 optional.
▶
With separate pipes (see Figure 3.4
p. 13). In this
case, it is necessary to use the separate exhaust casing
available as OCFF002 optional.
Warnings
The installation of pipes with a vertical downward
outlet is prohibited (leads to recirculation of flue
gas with lock-out of the appliance).
It is forbidden to install coaxial pipes with a vertical
outlet upwards (due to rain, water, objects infiltra-
tion with consequent lock out of the appliance).
