An attention should be paid to route cables supplying energized equip-
ment away from the boiler components that become hot during operation
(flue, doors).
It is recommended to connect the heating device on a separate power circuit
with a protective device in the main switchboard.
An emergency power supply for the heating system (controller, fan, gearmotor,
circulatory pumps, mixing valves with an actuator) should be provided in the event
of power outage, from additional equipment: UPS with a sine wave output or a
power generator.
8. GUIDELINES FOR USE AND OPERATION
NOTE!
Before starting operation an experienced installer should train the
user in rules for operation and maintenance of the boiler and the
whole heating system. A person operating the boiler should be ac-
quainted with statuses of the incorrect device operation and with
procedures for dangerous situations.
8.1. FILLING WITH WATER
Before the first start-up of the boiler, the water tightness test of the
whole heating system should be performed. Before the tightness test is
started, the whole system should be effectively rinsed with water to re-
move any possible contaminations which could affect the boiler operation.
Water used to fill the boiler and the heating system should be clean,
free of aggressive chemical compounds or oil, and meet requirements
of current regulations (PN-C-04607:1993 Water in heating systems – Re-
quirements and tests concerning water quality).
