Appliance Gas Connection & Commissioning - Rinnai RF1200TW Operation & Installation Manual

APPLIANCE GAS CONNECTION & COMMISSIONING
Once the engine has been installed and fixed to the building the gas and electricity can be connected. Some
installers elect to leave this until the decorating has been completed and the installation can be finished, remember
that the trim can not be attached until the wall lining is finished.
If commissioning is to be carried out after the decorating has been completed, leave a protective
cardboard cover taped to the front of the engine using a low-tack tape to prevent plaster dust and
debris from entering the engine and damaging the paint work.
CAUTION
Isolate the power and gas supplies before commencing work on the appliance.
