1.1.15. GAS CONNECTION
WARNING
The gas piping must be installed according
to all local and state codes, or in absence of local and
state codes, with the latest “Natural gas and propane
installation code”, CAN/CSA-B 149.1 or “National
Fuel Gas Code”, ANSI Z223.1 (NFPA 54). Consult
the “Natural gas and propane installation code” or
“National Fuel Gas Code” for the recommended gas
pipe size of other materials.
BEFORE PERFORMING THE GAS CONNECTION,
MAKE SURE THAT:
› The gas line size and length meets requested;
› The gas line is equipped with all safety and
control devices required by the standards in
force;
› The internal and external seals of the gas inlet
lines of the plant are checked;
› The device is suitable for use with the type of
gas available by checking the boiler data plate
(located on the inner side of the front casing. If
they do not match you must take the necessary
measures to adapt the boiler to another type of
gas (see chapter CONVERSION TO A DIFFERENT
GAS TYPE);
› The gas supply pressure falls within the values
indicated on the data plate.
1.1.16. ELECTRICAL CONNECTION
DANGER
The equipment is electrically safe only
if it is properly connected to an efficient grounding
system, performed in compliance with the safety
standards in force (National Electrical Code, ANSI/
NFPA 70 and or the Canadian Electrical Code Part
I, CSA C22.1, Electrical Code). You should check this
essential safety requirement. If in doubt, request an
accurate check of the electrical system performed by
qualified staff, as the manufacturer is not responsible
for any damages caused by lack of grounding system.
› Make sure that the electrical systems is
suitable for the maximum power consumed by
the equipment, value indicated on the data plate.
› Make sure that the cables section is appropriate
for the maximum power consumed by the
equipment.
› The equipment works with alternating current
of 120 V and 60 Hz. The electrical connection
must be installed using an all-pole switch with
an opening of at least 0.12 in (3 mm) between
contacts placed upstream from the device.
WARNING
Make sure that the phase and neutral
cables connection is installed in compliance with the
wiring diagram (see 1.1.17 POWER SUPPLY).
WARNING
It is strictly forbidden to use adaptors,
multiple plugs and/or extensions for the general
power supply of the equipment from the electrical
supply.
