Logano GB125 oil condensing boiler - Technical specifications are subject to change without prior notice.

3.4
Balanced flue operation
The boiler meets the requirements specified by the ap-
probation principles of the DIBT for balanced flue oil
combustion equipment to EN 15034/15035
(
Chapter 3.2, page 10 "Declaration of Conformity").
The entire system (ventilation air pipe - burner/boiler -
flue gas pipe) corresponds to the types of oil combustion
equipment shown in the table on the right. The additional
designation "x" declares that the combustion equipment
meets the sealing demands and can therefore be opera-
ted independently of the equipment and ventilation in the
boiler room.
Observe the country-specific standards and regulations
concerning the operation of balanced flue oil combustion
equipment.
Please ensure that, when connecting the appliance to a
balanced flue system that has not been tested with the
boiler (OC
63x
), the country-specific requirements (parti-
cularly concerning the design of the terminal) and the
specifications of the general building regulations apper-
taining to the system are observed.
For the technical details regarding the sizing of the ba-
lanced flue system for OC
63x

Installation
type
Routing combustion air and
flue gas
OC
13x
Concentric combustion air supply and flue gas routing horizontal through the outside wall. The terminals are loca-
ted close beside each other in the same pressure area. Combustion air supply and flue gas routing are part of the
combustion equipment.
OC
33x
Concentric combustion air supply and flue gas routing vertical via roof. The terminals are located close beside
each other in the same pressure area. Combustion air supply and flue gas routing are part of the combustion
equipment.
OC
43x
Connection to air-flue gas system (LAS, simply laid); ventilation air pipe from air shaft and connecting piece for
chimney are part of the combustion equipment.
OC
53x
Separate combustion air supply and flue gas routing (tested together with the boiler). The terminals are located in
different pressure areas. Ventilation air and flue gas pipes are part of the combustion equipment.
Please note: When routing the flue gas horizontally, then the terminals must not be on opposite walls of the buil-
ding.
OC
63x
Designed for the connection to a combustion air supply and flue gas routing system, not tested with the boiler.
OC
83x
Connection to a flue gas system (underpressure operation). Ventilation air pipe and connecting piece to the chim-
ney are part of the combustion equipment.
