Designed for Ease of Maintenance
The appliance has been designed and engineered to be easy to maintain, with most major service
operations being quick and easy to complete with the minimum of tools.
Each module can operate independently, without affecting the service of the other modules within 
the system.
To facilitate the annual inspection and cleaning of the syphon, there is a rinsing pipe at the back of the
unit. The condense is led through a built-in syphon to a plastic connection at the back, where a suitable
connection can be made to the termination point.
Operational Data Logging
Each burner assembly has a data logging facility to record operational actions, which can be accessed
via an RS232 communication from a PC. This facility provides a useful service tool as it allows a record of
operation to be viewed and any faults to be identified.
