CDA HCG450 - Manual (Page 9)

To perform these operations the qualified installer will follow the indications
given in the "Adaptation to the various types of gas" section.
For safety operation make sure that the supply pressure respects the values
given in the "Table of burner and injector characteristics”.
If the appliance is supplied with liquid cylinder gas, make sure that the cylin-
der pressure regulator conforms to the local regulations in force.
The appliance must be connected to the gas system by a rigid metal pipe
(copper or steel) or continuous wall stainless steel flexible hose in such a
way that the appliance is not stressed in
any way.
The appliance gas inlet tube has an end
nut to which is connected the elbow union
(supplied; 1/2 thread male gas). It can be
turned depending on installation needs.
The rigid or flexible metal supply pipe (l
max = 2mt) is connected to the part oppo-
site the elbow union. Remember to put the
gaskets supplied at the two ends of the
elbow union.
When these parts are disassembled and
reassembled, always replace the gaskets
with new ones.
Once the appliance is installed, check that the gas pipe is not pinched or
damaged by mobile parts.
Important: when installation is complete, check that all the gaskets are
leaktight using a soap-based solution, never a flame.
