Switching Off; Periodical Maintenance - Joannes DRY 20 Handbuch

CHECKS AND CONTROLS
PRIOR TO THE INITIAL STARTING UP
Before the initial starting up, it is a good rule to check that:
a the system is refilled to the correct pressure and well purged;
there are not any leakages of water or fuel;
b
c the electrical supply is correct;
d all the smoke conduit has been installed properly and is not too close or crosses inflammable parts;
e there are not any inflammable substances in proximity of the appliance;
f the burner is in proportion to the boiler output;
g the water interception valves are open.
AFTER THE INITIAL STARTING UP
After the first starting up it is a good rule to check that:
●
the burner functions properly.
This check must be made with the appropriate tools;
●
the thermostats function correctly;
●
the water circulates in the system;
●
the smoke evacuation is effected exclusively through the chimney.
STARTING UP - SWITCHING OFF
INITIAL STARTING UP
After carrying out the preliminary checks,it is possible to proceed with the following starting operations:
1 open the fuel interception valve (if any);
2 adjust the boiler thermostat (Fig. 2) to the desired value;
3 shut off the upstream switch on the boiler and the on/off switch (Fig. 2) situated on the control panel.

SWITCHING OFF

For brief periods of rest it is sufficient to use the on/off switch (Fig. 2) situated on the control panel.
For long rest periods during the winter period, in order to avoid damages caused by freezing, it is neces-
sary to introduce the appropriate anti-freeze fluid into the system or otherwise empty the latter completely.

PERIODICAL MAINTENANCE

The maintenance of the boiler must be carried out by Qualified Personnel.
It is a good rule to have a check of the appliance carried out at least once a year, before the winter season.
Such a check should concern, besides the condition of cleanliness of the boiler, the correct functioning of all
its control and safety devices as well as the burner itself.
In addition the state of the smoke exhaust should be checked.
