1.16 GAS SYSTEM STARTUP.
To start up the system, make reference to the
Standard: is divides the systems and therefore
the start-up operations into three categories: new
systems, modied systems, re-activated systems.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or naked ames;
- bleed all air from pipelines;
- check that the internal system is properly sealed
according to the regulations in force.
1.17 BOILER START UP IGNITION.
For issue of the Declaration of Conformity
provided for by Italian Law, the following must
be performed for boiler start-up:
- check that the internal system is properly sealed
according to the regulations in force;
- ensure that the type of gas used corresponds to
boiler settings;
- switch the boiler on and ensure correct ignition;
- check that the no. of fan revs is that indicated
in the book (Par. 3.21);
- ensure that the safety device is engaged in the
event of gas supply failure and check activation
time;
- check activation of the master switch located
upstream from the boiler and in the boiler;
- check that the concentric intake-exhaust
terminal (if tted) is not blocked.
e boiler must not be started up even if only
one of the checks should be negative.
N.B.: the boiler preliminary check must be carried
out by a qualied technician. e conventional
boiler warranty is valid as of the date of testing.
e test certicate and warranty is issued to the
user.
1.18 CIRCULATION PUMP.
e “Victrix 50” series boilers are supplied with
a built-in circulation pump with 3-position
electric speed control. e boiler does not operate
correctly with the circulation pump on first
speed. To ensure optimal boiler operation, in the
case of new systems (single pipe and module) it
is recommended to use the pump at maximum
speed. e circulation pump is already tted
with a capacitor.
Pump release. If, aer a prolonged period of
inactivity, the circulation pump is blocked,
unscrew the front cap and turn the motor sha
using a screwdriver. Take great care during this
operation to avoid damage to the motor.
