Installation instructions Logamax plus GB162-80/100 cascade unit • Version 01/2006
Items supplied with unit 2
Buderus supplies cascade systems in
TL
and
TR
configurations:
TL: Inline installation
All boiler assemblies are in a line enabling an easy-to-monitor
installation in a narrow room.
TR: Back-to-back installation
The boiler assemblies are located on both sides of the frame
and are installed back-to-back to create a compact installation
which ideally suits rectangular rooms and which ensures the
best possible access to all boilers.
The relevant configuration can be selected on the basis of the
performance required (see table 1).
Boiler assembly connection kit
The connection kit can be used both for the Logamax plus
GB162-80 and for the 100-kW version. The connection kit
includes a pressure relief valve, a non-return valve, a pump
and isolating valves.
Bend sets with low loss header
The Logamax plus GB162 cascade system can be installed in
various configurations (fig. 4). By using the bend set the low
loss header can be installed at an angle to the boilers. The gas
pipe is reversible so that the gas connection can be at the other
side of the boilers to the flow and return connections to the
header.
