a. CL SERIES WATER BOILER - Figures 11A
and 11B show indirect water heater piping on
typical hot water heating system. Boiler piping
is the same as for any two-zone system. Figures
11A and 11B show circulator zoning, which is
usually preferred for indirect water heaters. Size
the circulator and indirect water heater piping to
obtain the boiler water flow through the indirect
water heater called for by the indirect water
heater manufacturer. Refer to the indirect water
heater instruction manual for additional details.
b. CL SERIES STEAM BOILER - All CL Series
steam boilers are equipped with tappings to
permit the connect of an indirect water heater,
see Figures 2B and 15. In this type of system,
hot boiler water is drawn from below the water
line and passed through the heat exchanger in the
indirect water heater.
This section describes boiler-side piping only.
Refer to the indirect water heater instruction
manual for additional details.

INSTALL SMOKEPIPE — The CL Series boiler
should be vented into a fireclay tile-lined masonry
chimney or chimney constructed from type L vent or
a factory built chimney that complies with the type
HT requirements of UL103. The chimney and vent
pipe shall have a sufficient draft at all times, to assure
safe proper operation of the boiler. See Figure 16 for
recommended installation.
1. Install a draft regulator (supplied by installer)
following the instructions furnished with the
regulator. See Figure 17 for draft regulator locations.
2. Consider the chimney overall. Chimneys that have
a high heat loss may become less suitable as the
heat loss of the home goes down and the efficiency
of the boiler installed goes up. Most homes have
a chimney appropriate for the fuel and the era in
which the home was built. That may have been a
coal fired or an inefficient oil fired boiler built into
a home without insulation or storm windows. With
increasing fuel prices that home probably has been
insulated and fitted with storm windows so that
the heat loss of the home has been reduced. This
requires less fuel to be burned and sends less heat up
the chimney.
A new boiler probably has a higher efficiency than
the boiler being replaced. That probably means that
the stack temperature from the new boiler will be
lower than that from the old boiler and with less
room air being drawn up the chimney to dilute the
stack gases. The combination of a large uninsulated
chimney, reduced firing rate, reduced firing time,
