Do not place mountings allowing for the total or partial closure of the flow or devices and
mountings reducing the internal cross-section on safety pipes, expansion pipe, overflow pipe and
venting pipe.
INFO: The minimum capacity of the expansion vessel is calculated according to the formula [1] - PN-91/B-
02413 p. 2.5.1.
INFO: Equipment and placement of the expansion vessel is determined by PN-91/B-02413 p. 2.5.2.÷2.5.4.
Expansion vessel, safety pipes, expansion pipe, signal pipe and overflow pipe must at a place where the air
temperature is not lower than 0 ° C.
INFO: If the expansion vessel is at a place where the air temperature drops below 0°C , use circulation
pipes and safety pipes connecting the expansion vessel with the boiler, as well as thermal insulation
according to PN-91/B-02413 p. 2.11. Thermal insulation of safety devices is to protect them against
freezing only during short interruptions of heating.
NOTE! – The lack of thermal insulation and placing the expansion vessel not in accordance with PN-91/B-
02413 identified during warranty claims for leaks during temperature drops below 0°C
can be grounds for not accepting the complaint and refusing to repair or replace the boiler.
Before operation, pay attention to the following instructions on personal safety:
• Using the boiler with open doors is prohibited.
• Using ignition accelerators in the boiler is prohibited.
Before start-up, check the correctness of connection and the operation of the following devices and
systems:
• Tightness of the heating system (exhaust side and water side)
• Connection of the exhaust system and flue duct
• Correct position of chamotte fittings the combustion chamber
6.2 Initial commissioning
DANGER: Lethal danger cause by chimney
fire!
Before the first start-up, have a supervisory body control the
exhaust system.
Provide the user with the control report.
Check the tightness of the exhaust pipe.
No not make any structural modifications in the boiler.
WARNING: Damage to the system or risk of injuries due to improper start-up!
Improper position of lack of chamotte fittings inside the boiler can lead to
damage or destruction of the boiler.
Installation and modification of the boiler can be made only by an authorized installation
company.
Before the first start-up, check the position of chamotte fittings inside the boiler.
WARNING: Damage to the system due to improper operation!
