15.4 GAS SUPPLY
The gas supply pressure, the gas flow and the dimensions of the gas connection, they all depend on the type of
gas used, according to the boiler installed and the current regulations.
Gas connection: the installing company has to install a three-pieces coupling per boiler in order to facilitate the
dismantling and the maintenance of every boiler.
The boiler incorporates a small mesh. If the connecting pipe is not clean or has particles, the mesh will
immediately block, so the installing company will have to install a gas filter before the boiler gas connection.
If the boilers gas pressure is higher than the maximum value indicated in this manual, it is necessary to install a
gas pressure governor so that the inlet working pressure can be in accordance with the values required.
It is advisable to install a flue gas header previous to the boilers that will operate as a gas inertial tank when the
boilers start working.
When different consumptions are simultaneously required, the dimensions of the gas pipes and of the gas
connections must be calculated so that, when all the consumptions are demanded simultaneously, the inlet
working gas pressure to each boiler will correspond to the values indicated in this manual (see table
TECHNICAL DATA).
15.4.1. Gas pressure higher than 45 mbar.

A gas pressure governor must be installed to reduce
pressure to a value in accordance with the table of
paragraph “Technical data”. To select the type and its
speed of opening/closing, consult the Technical
Department of ADISA CALEFACCIÓN.
An inertial tank must be installed between the gas
pressure governor and the boiler, acting as a gas
inertial volume when the boiler starts up and as an
absorber/compensating of the pressure rise produced
by the closing of the gas pressure governor when the
boiler stops (see diagrams below).
Its volume will be at least equal to 1/1000 of the boilers
maximum flow per hour.
This inertial tank must be placed as close as possible
to the boiler.
