1.3 CONNECTIONS

Gas connection:

The boiler is designed to operate with Natural

gas (Cat I2H 2H - G20 - supplied at 20 mbar)

or Propane gas (Cat I3P 3P - G31 - supplied

at 37 mbar). Supply pipes must be the same

as or larger than the 3/4" boiler fitting. Before

connecting the gas line, carefully clean inside all

the supply pipes to remove any residue that could

impair boiler performance. Also make sure the

gas corresponds to that for which the boiler is

prepared (see boiler data-plate).
The gas supply pipe must be suitably dimensioned

according to current regulations in order to

guarantee correct gas flow to the burner even

in conditions of maximum boiler output and

to guarantee appliance efficiency (technical

specifications).

Storage tanks (LPG):

- New LPG storage tanks may contain residual

inert gases (nitrogen) that degrade the mixture

delivered to the appliance causing functioning

anomalies.

- Due to the composition of the LPG mixture,

layering of the mixture components may occur

during the period of storage in the tanks. This

can cause a variation in the heating power of

the mixture delivered to the appliance, with

subsequent change in its performance.

Hydraulic connection:
Important:

in order not to void the warranty

before making the boiler connections, carefully

flush the heating system (pipes, radiators, etc.)

with de-scaling products to remove any deposits

that could compromise correct boiler operation.
For further detail see Section 1.12.
