CAUTION!!!
Minimum air gap
of ½” between
discharge pipe and
drain. Failure to do
this will damage
the unit and void
warranty.
5 - INSTALLATION - Mounting & gas and water connections
5.8 - Relief valve
Each boiler is equipped with a safety
relief valve set at
30 psi (2 bar) which
must be piped in accordance with
the ANSI/ASME Boiler and Pressure
Vessel Code, Section IV, to prevent
scalding in the event of a discharge,
see Figures 1, item “38” and fi gure 10.
WARNING!!! Failure to properly
pipe the relief valve discharge can
result in scalding of individuals and
animals. Never install any type of
valve between the boiler and the
relief valve or an explosion causing
extensive property damage, severe
personal injury or death may occur!
CAUTION!!! Before
connecting the boiler to the heating
system the heating system must
be thoroughly fl ushed to remove
sediment, fl ux, fi lings and other
foreign matter. An approved
inhibitor should be added to the
heating system water to prevent
limestone and magnetite deposits
from forming and to protect the
boiler from galvanic corrosion.
CAUTION!!! This boiler is
equipped with an ASME safety
relief valve set at 30 psi (2 bar). The
heating system must be designed
so that no piping or radiation
elements are higher than 65 ft (20
m) or else the hydraulic head of the
system will cause the relief valve to
open.
CAUTION!!! The
manufacturer cannot be held
responsible for any damage caused
by incorrect use of additives in the
heating system.
5.9 - Supply and
return piping
CAUTION!!! All heating
system piping must be installed in
accordance with the ANSI/ASME
Boiler and Pressure Vessel Code,
Section IV. All applicable local
codes and ordinances must also
be followed. If the boiler is installed
above any radiation elements it
must be fi tted with a low water
cutoff device installed above the
normal boiler water level! Failure
to do this can result in damage the
unit and void the warranty!
CAUTION!!! This boiler
must have adequate water fl owing
through it whenever the burner is
on. Failure to do this will damage
the unit and void the warranty!
