Close fuel shut off devices prior to starting work.
Care should be taken when dismantling and assembling gas carrying compon-
ents.
Close the screws on the test points ensuring the tests points are sealed.

Allow components to cool.
Servicing must only be carried out by qualified personnel. The combustion plant
should be serviced annually. Depending on site conditions more frequent checks
may be required.
Components, which show increased wear and tear or whose design lifespan is or
will be exceeded prior to the next service should be replaced as a precaution.
The design lifespan of the components is listed in the service plan [ch.9.2].
Weishaupt recommends a service contract is entered into to ensure regular in-
spections.
The following components must only be replaced and must not be repaired:
