APPLIANCE GAS CONNECTION & COMMISSIONING
CAUTION
ISOLATE THE POWER AND GAS SUPPLIES BEFORE COMMENCING WORK ON THE APPLIANCE.
Once the engine has been installed and xed to the building the gas and electricity can be connected, however
some installers elect to leave this until the decorating has been completed before nalising the installation.
CAUTION
If commissioning is to be carried out after the decorating is completed, then leave the protective
plastic coverings in place and cover the front of the engine with cardboard and low-tack tape to
prevent plaster dust and debris from entering and damaging the appliance.
Refer to the diagram below for part identication.
