NOTE:
Refer to manual section "LOCATING
THE BOILER" for required
clearances
for servicing
and maintenance.
CAUTION
Copper
supply and return piping must NOT be installed directly into aluminum boiler section castings
due to galvanic corrosion
between
dissimilar
metals. Iron or steel bushings or pipe nipples should be
used between
copper system piping and boiler to make final connection
to boiler. Also, the use of
dielectric
unions is acceptable.
The packaged
boiler is furnished with iron piping in the front boiler
section for the supply and return connections.
When the installation
of the boiler is for a new heating system, first install all of the radiation units
(panels,
radiators,
baseboard,
or tubing) and the supply and return mains. After all heating system
piping and components
have been installed,
make final connection
of the system piping to the boiler.
A hot water boiler installed above radiation level must be equipped with a low water cut off device. A
periodic
inspection
is necessary,
as is flushing of float type devices,
per low water cut off
manufacturers
specific instructions.
A. SUPPLY AND RETURN LINES
The packaged boiler unit is set up to receive 1 _,_"NPT supply and return piping from top access.
The boiler unit can also be piped from the left side by turning the supply elbow, and from the rear
of the unit by removing plugs in the rear boiler section.
NOTE:
The circulator pump and isolation valves are furnished within a carton inside the boiler
cabinet and can be installed at the installer preferred location.
