Zeus Mini Instructions
It is often necessary to install a longer flue system to cater for site
conditions. There are several different flue system sizes available
for the Zeus Mini boiler.
Horizontal concentric kit 60 /100
The exhaust pipe (φ 60 mm) is fitted inside the air intake
pipe (φ 100 mm). Connection to the boiler is made using a 90°
bend (1) which can be turned in any direction and can be connected
to the terminal (2).
Max possible overall length after the first bend (1) is
3 straight and horizontal metres.
Horizontal concentric kit 80 /125
The exhaust pipe (φ 80 mm) is fitted inside the air intake
pipe (φ 125 mm). Connection to the boiler is made using a 90° bend
diameter 60/100 (1) which can be turned in any
direction and connected using the adapter 60/100-
80/125 (2) to the 80/125 terminal (3).
Max possible overall length beyond the first bend(1) is
7.3 straight and horizontal metres.
Vertical concentric kit 60 /100
The exhaust pipe (φ 60 mm) is fitted inside the
air intake pipe (φ 100 mm). Connection to the boiler is made using
a flange (1) which may be connected to the 60/100 vertical terminal.
Max possible overall length is 4.7 straight and
vertical metres.
Vertical concentric kit 80 /125
The exhaust pipe (φ 80 mm) is fitted inside the Air intake pipe (φ
125 mm). Connection to the boiler is made using a flange (1). The
adapter 60/100-80/125 (3) is used the connect the 80/125 terminal
(2). Max possible overall length is 12.2 straight and
vertical metres.
Separated 80/80 flue kit
Both pipes have a diameter of 80 mm. Connections to the boiler are
made using two special flanges for exhaust (1) from the centre pipe
and extraction (2) from one of the two side holes.
Max possible length (extr exhaust) is 33 straight horizontal
metres and 41 straight vertical metres.
To prevent condensation problems, the exhaust pipe should
not be more than 5 m long. Advice on prevention of condensa-
tion is available from RVR Limited. Please contact us when
designing longer flue systems.
Separated 80/80 insulated flue kit
Both pipes have a working diameter of 80 mm.
Connections to the boiler are made using two special
flanges for exhaust (1) from the centre pipe and
extraction (2) from one of the two side holes.
Insulation is obtained thanks to special seals (3)
whereby an air space can be created by means of a φ
125 mm external concentric pipe.
Max possible length (extr exhaust) is 33
straight metres.
To prevent condensation problems, the exhaust pipe
should not be more than 12 m long
