1.1.1. GENERAL INSTALLATION
WARNINGS
This water heater must be installed in accordance
with local codes, if any; if not, follow the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CAN/
CSA B149.1, as applicable.
WARNING
This unit may be used only for the
purpose for which it has been designed: heat water
to a temperature below boiling point at atmospheric
pressure. Any other use is considered wrong and
dangerous. The manufacturer is excluded from
any contractual or out of contract responsibility for
damage caused to people, animals or property due
to errors during installation.
WARNING
This water heater should be installed
only by qualified personnel, having the appropriate
technical training in the field for the installation and
maintenance of components of civil and industrial
domestic hot water production and heating plants.
WARNING
After having removed the packing, make
sure the equipment is intact. In case of doubt, do
not use the equipment and contact the supplier.
BEFORE INSTALLING THE WATER HEATER
THE INSTALLER MUST MAKE SURE THAT THE
FOLLOWING CONDITIONS ARE PRESENT:
› The unit is connected to a heating unit and a
water supply network appropriate for its power
and performance.
› When using room air for combustion, the
location must be properly vented through an air
vent.
› A temperature and pressure relief valve , rated
for 150 psi and 210F, is factory installed with the
appliance. No valve is to be placed between the
relief valve and the tank. The discharge from
temperature and pressure relief valves will
be conducted to a suitable place for disposal
when relief occurs and no reducing coupling or
other restriction be installed in the discharge
line. The discharge line be installed to allow
complete drainage of both the valve and line.
› The unit is suitable for use with the type of gas
available by checking the water heater data plate
placed on the inner side of the front casing.
› Make sure that the gas lines are properly sealed
without any gas leaks.
› Make sure that the grounding system works
properly.
› Make sure that the electrical system is suitable
for the maximum power required by the
equipment, value indicated on the data plate.
WARNING
Use only original RADIANT optional or
kit accessories (including electrical).
1.1.2. WATER HEATER LOCATION
ENVIRONMENTAL
REQUIREMENTS
Thewaterheatershallbeinstalledsothegasignition
system components are protected from water
(dripping, spraying, rain, etc.) during appliance
operation and service (circulator replacement,
condensate trap, control replacement, etc.).
The water heater installed using inside air supply
must provide provisions for Combustion Air and
Ventilation Air in accordance with section 5.3, Air

SFK 57 - RAD - ING - Inst. Manual - 2210.1_SKM1_firm.L188i58_CSA
1. INSTALLATION
INSTALLER
for Combustion and Ventilation, of the National
Fuel Gas Code, ANSI Z 223,1/NFPA 54, or section
7,2, 7.3, or 7.4, of CAN/CSA B 149, Installation
Codes, or local codes having jurisdiction.
Where an exhaust fan or any other air consumption
appliance is installed in the same space as the
water heater, sufficient air openings must be
available to provide fresh air when all appliances
are operating simultaneously. It is essential that
in rooms where the water heater is installed
to provide as much air as required by normal
combustion of the gas consumed by the various
appliances. Consequently, it maybe necessary to
make openings in the walls to provide the air inlet
into the rooms.
For applications where air from the structure
is used to supply combustion air for the unit, the
following openings are required:
1. Have a total free section of a least 25 mm2every
kW (1 in2for every 1000 Btu/hr) of heat input, with
a minimum of 100 cm2(15.5 in2);
2. Where required by code or when required for
additional opening must be provided at the highest
practical elevation.
With a hermetically sealed combustion chamber
and air supply circuit from outdoors, the water
heater may be installed in any room in the
home. Keep water heater area clear and free
from combustible materials, gasoline and other
flammable vapors and liquids.
The appliance should be located in an area where
leakage of the tank or connections will not result
in damage to the area adjacent to the appliance
or to lower floors of the structure. When such
locations cannot be avoided, it is recommended
that a suitable drain pan, adequately drained, be
installed under the appliance. The pan must not
restrict combustion air flow.
WARNING
If the temperature in the water heaters
installation location goes below 35.6°F (2°C) ,
insert an electrical resistances kit .
1.1.3. REFERENCE LEGISLATION
This water heater must be installed in accordance
with local codes, if any; if not, follow the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CAN/
CSA B149.1, as applicable.
