Burnham Hydronics C3, Hydronics C4 User Manual
C3™ & C4™ SERIES
By combining cast iron durability
with state-of-the-art components
and controls, the C3 & C4 provide
effi cient and economical oil-fi red
hot water heating.
Cast iron absorbs and transfers
heat quickly and effi ciently while
providing unmatched durability.
Rugged
cast iron sections are
designed to extract the maxi-
mum amount of heat
which
reduces fuel consumption
and
saves you money.
Metal Push Nipples join all
cast iron sections and expand
and contract with the sections
ensuring durability. They are
impervious to petroleum-based
chemicals, which can deteriorate
gaskets used in some competi-
tors’ boilers.
The C3 & C4 Series Boilers are
designed for quick, inexpensive
servicing.
Jacket design allows entry from
both the top and side to allow
complete access for cleaning.
Burner swing door provides
easy access to the combustion
chamber for fast servicing.
Packaged and ready to
install with optional tankless
coil for domestic hot water.
Circulator is prepiped and wired
for on the spot installation.
