5.9. BOILER LONG-TERM SWITCH OFF
When switching the boiler off for long period of time (at the end of the heating season), it must
be completely cleaned from all unburned accumulations (soot, ash and deposits). Otherwise
the accumulation of moisture in the unburned gasses leads to excessive boiler corrosion.
Warning
The boiler can be operated only by adult people who are well introduced with the
current manual for operation.
Switch off the boiler every time when there is any (even momentary) danger by the
presence of flammable or explosive vapors situated in the same room from which
the boiler intakes air for burning (for example painting paint, spraying or laying
molten substances, gas leakage, etc.).
Boiler initial firing with explosive substances is strictly forbidden.
Boiler overheating is forbidden.
The boiler and the chimney have to be completely cleaned at the end of the heating
season. Also grease all hinges, chimney flap mechanism and other moving parts.
5.10. BOILER MAINTENANCE
Maintenance of the boilers from series BiSolid Comfort 03/04/05 has to be performed daily,
periodically or early.
During the daily maintenance the user must clean the unburned residues in the combustion
chamber, to clean the ash gathered in the combustion chamber and to dump the ash from the
drawer.
It is important that the user performs periodical maintenance of the appliances, in order to
achieve effective usage, prevention of possible problems with its operation and optimum boiler
life cycle. We recommend periodical check on every 3 months. Such checks have to be
performed by authorized servicing technicians and should include the following activities:
Check boiler’s combustion chamber and flue pipe, including the chimney. They should
be cleaned if necessary.
Check for leakages of incoming or outgoing water, in and out of the boiler, water pipe
links as well.
Check valves, fittings and accessories.
Check circulation pumps.
Visual check of the fire-grate.
Perform operation control check for safety of the hydraulic system and the boiler.
The yearly maintenance (prophylaxis) of the boiler must be performed only by authorized
technicians, before the start of the heating season. Before calling the servicing technicians the
user has to provide already cleaned flue pipes and chimney. During the yearly prophylaxis the
authorized technicians perform the following checks and activities:
Position of the combustion chamber shaft, isolation and isolation ropes.
Boiler test at operating pressure for adjustment of the burning, by measuring flue gas
parameters if necessary.
Check and clean the boiler’s fire-grate and surfaces from soot and ash.
Test boiler connections for leakages.
Check fittings including muffs, mixing valves, pressure valves for reliability.
