The appliance gas supply pressure, both static and dynamic, must comply with the values in the Table, with a tolerance of ± 15%.
3.2.5 Vertical pipes and condensate
▶ Vertical gas pipes must be tted with siphon and dis-
charge of the condensate that may form inside the
pipe.
▶ If necessary, insulate the piping.
3.2.6 LPG pressure reducers
With LPG the following must be installed:
▶ A rst stage pressure reducer, close to the liquid gas
tank.
▶ A second stage pressure reducer, close to the appli-
ance.
3.3 COMBUSTION PRODUCTS EXHAUST
Compliance with standards
The appliance is approved for connection to a
combustion products exhaust duct for the types
shown in Table 1.2 p.14 .
3.3.1 Flue gas exhaust connection
▶ Ø 110 mm, on the rear side, at the top (see dimension-
al drawings in the 1.2 p.8 Section).
3.3.2 Combustion air intake tting
▶ Ø 130 mm, on the rear side, at the top (see dimension-
al drawings in the 1.2 p.8 Section).
3.3.3 Installation types
If ducts other than those supplied by the manufac-
turer are used, make sure that they are suitable for
the unit on which they are installed. In particular,
the temperature class of the duct must be ap-
propriate for the operating characteristics of the
unit, and must also respect the chemical-physical
stability of the system itself.
In any case, use approved ducts according to the
type of installation to be made. Upon request,
Robur can supply rigid pipes, coaxial ducts and ter-
minals, all of approved type.
Gas unit heaters of the M series can be installed to one of
the following ways.
