Heed the following points for connecting the
fuel supply:
B Work on gas components may only be
carried out by qualified and authorized
personnel.
B Observe the local regulations or else the
requirements the National Fuel Gas Code,
ANSI Z 223.1 when connecting the gas
supply. In Canada, the requirements of
CAN/CSA-B.149.1 and 2, Installation
Guidelines, must be observed.
B A gas shut-off valve must be installed
outside the boiler casing if required by the
local code. We recommend installing a
gas shut-off valve in the main gas pipe to
the boiler.
B The gas pipes must be fastened outside
the boiler.
The gas feed pipe is designed for a gas
connection on the right side.
For the conversion to left-side gas
connection, see section 5.1.
To prevent strain on the gas valves,
extensions of the gas supply line must be
supported.
