- Page 2 Congratulations on your selection. Your modulating boiler is electronically adjusted and ignited. • highly efficient; • sealed chamber. Unlike traditional boilers, your condensation boiler makes it possible to recover energy by con- densing the water vapour contained in the flue gas; that is, with equal heat production, it con- sumes less gas and furthermore, the flue gas contains fewer substances that are harmful to the environment.
- Page 3 IMPORTANT The manual must be read carefully in order to use the boiler in a rational and safe manner. It must be stored with care as it may be necessary to consult it in the future. If the unit is trans- ferred to another owner, the manual must accompany the boiler.
- Page 4 Before starting the boiler, it is recommended to have professionally qualified personnel check that the gas supply system: • Is perfectly sealed. • Is dimensioned for the flow rate necessary to the boiler. • Is equipped with the safety and control devices required by current standards; • Make sure that the installer has connected the safety valve discharge to a discharge funnel. The manufacturer is not responsible for damage caused by the water released when the safe- ty valve opens if it is not correctly connected to a drain.
