The
PF-3... is
an excellent
heating unit for
application in smaller
apartment
or commercial
buildings.
Designed
specifically for
ligh"t
oil,
forced draft
firing this
cast
iron sectional unit
is
available either
as
a steam or
hot
water boiler and attains a
combustion efficiency
of over
83%.
Forced draft boilers,
in addition
to increased
operating efficiencies,
require
much less space
than
conventional boilers of
comparable
rating and eliminate
the
need for
external
draft
devices such as a
high chimney
or
mechanical draft equipment-the
PF-3
features:
compact
wet base design;
no
separate
base
or combustion chamber;
and
the
provision
for
tankless heater in both
steam and water boil-
ers.
The boiler
also features a
high
efficiency burner and the use
of
an elastic
sealant compound
for
sealing.
