1. INTRODUCTION
In this instruction manual is described condensing gas system boiler
ECOCONDENS CRYSTAL designed for supplying a central heating
system and heating domestic water in separately connected a
domestic water tank.
Adaptation of the following boiler to work with the tank
needs to be made by AUTHORISED SERVICE COMPANY.
ECOCONDENS CRYSTAL boiler take the air for combustion process
from outside the room (in which combustion circuit is sealed) with
respect to the residential area of the building in which it is installed -
type of installation: C13, C33, C43, C63 or take the air for combustion
process from the room that meets appropriate conditions (required
by law) - type of installation: B23 .
Further information regarding the type
–
according section 3.8 or PN-
EN 15502 Standard.
