particular reference to measuring the differential air
pressure. Refer to Commissioning and Testing (pages
22-25).
Gas Injector
1.
Unscrew the injector from the end of the gas outlet pipe.
2. Fit the replacement injector, renewing the gasket and
ensuring that the gap between the gas distribution plate
