FLAMMABLE GASES
As standard, the eCOMFORT range is supplied with R32 refrigerant which is a ammable gas classied A2L (slightly ammable).
A2L / A2 / A3 ammable gases are subject to more important safety regulations than gases classied A1. This section summarizes
the standard and provides specic Lennox recommendations. This section is based on the standards as well as numerical simulations
and tests related to the ammability risk carried out on these products. It provides the recommendations to be considered so that the
product is installed, used, maintained and destroyed at the end of its life cycle without putting the actors in the product life cycle at risk.
FLAMMABILITY CLASS
A1 Non-ammable
A2L Slightly ammable
A2 Low ammable
A3 Highly ammable
LABELS OF FLAMMABLE GAS UNIT:
The A2L logo on the nameplate indicates that the product contains refrigerant of the slightly ammable category. It is
also positioned on schraders where refrigeration components can be connected for maintenance. This label tells you that
there is a potential risk of a ammable gas leak and that this should be taken into account in the operational risk analysis.
TRANSPORT OF FLAMMABLE GAS UNIT:
