Miele PDR 914 User Manual

Installation
*INSTALLATION*
62
 Before completing commissioning, maintenance, conversion,
and repair work, all gas-conducting components – from the manual
shut-off valve to the burner jet – must be checked for leaks.
Particular attention must be paid to the measuring stubs on the gas
valve. Checks must be performed when the burner is both switched
on and switched off.

Installing thermal shut-off equipment on site is recommended.

If gas-heated appliances are accessible to anyone, it is also neces-
sary to check whether a gas flow monitor needs to be used.
