Propane Installation Code.
This appliance is designed for
heating water to a temperature
below its boiling point at
atmospheric pressure.
- It must be hooked up to a
heating system and to a sanitary
hot water distribution system
compatible with the
characteristics, performance and
power ratings of the water heater
itself.
- Before installation it is
necessary to thoroughly flush
the heating and plumbing
systems, in order to remove any
residues or impurities which may
compromise the correct
functioning of the water heater .
- This water heater is not suitable
for outside installation unless an
outside installation kit is
installed with the heater. .
Choose a place that is protected
from the atmospheric elements
i.e. rain, wind, sun and
especially frost, and which
complies with the requirements
prescribed by the applicable
national and/or local regulations.
- Refer to figure 4 for the minimum
clearance distances required for
installation and subsequent
servicing.

for the user
The installer must instruct the user
on the correct use of the water
heater , and in particular must:
 supply the installation and user
manual and all the
documentation contained in the
packing materials;
 instruct the user concerning the
special measures to be taken for
the discharge of flue gases, and
inform the user that these must
not be altered;
 inform the user concerning the

control of the water pressure
necessary in the system and the
necessary measures for filling
and for purging;
 inform the user on how to
correctly set the temperatures

3.3 - Clearances
for installation
Figure 4 shows the proper
distances that are allowed for the

3.4 - Clearances
from combustible
material
This appliance may be installed
directly onto a wall of combustible
material with the following
clearance:
Ceiling 8 inches
Front 2 inches
Rear 0 inches
Sides 2 inches
Floor 8 inches
3.5 - Choosing
the place of
installation
CAUTION!!! The water
heater must be installed on a
vertical wall that is able to support
its weight.
Heater may also be installed in a
closet or alcove.
Choose a location centralized to
the piping system with
consideration to the vent pipe
length. You will need to place the
space/water heater so that the
controls, drain, inlet/outlet, and gas
valve are easily accessed. Care
must be exercised when choosing
the location of this appliance,
where leakage from the safety relief
valves, leakage from related piping,
or connections, will not result in
damage to the surrounding areas,
or to the lower floor of the building.
Nothing should be installed
between the safety relief valves and
the heater. The discharge from the
pressure relief valve must be
connected to a suitable place for
disposal. No reducing, coupling or
other restrictions shall be installed
in the discharge line. The
discharge line should allow
complete drainage of both valve and
line.
Choose a suitable room and
position for installation, taking the
following factors into account:
- connection of the flue gas
discharge/air intake pipes;
- connection of the gas supply
piping;
- connection of the water supply;
connection of the central heating
system;
- connection of the sanitary hot
water system;
- electrical connections;
- possible connection for draining
the condensation produced by
the flue gas discharge system;
- possible discharge connection for
the safety relief valve.
