Component/Connection Locations; Optional Equipment - CleaverBrooks CFC-500 Operation, Service And Parts Manual

5. Component/Connection Locations

Figure 1-8 shows the CFC component orientation and heat flow
path. Note the downfired design of the burner and the orientation of
the hot water outlet and return connections. The return water
connection is at the bottom of the vessel and the hot water outlet is
near the top.
Figure 1-9 shows the locations of the safety valve and low water
cutoff. Figure 1-10 shows the location of the return water
temperature sensor. Looking at the top of the boiler, near the rear,
Figure 1-11 shows the three hole sensor well for the outlet
temperature sensor.
When standing at the back of the boiler, the stack can be connected
on the right side of the boiler (Figure 1-12) or on the left side. Refer
to Chapter 3 of this manual for recommended vent sizes and lengths
for the specific boiler installation.

6. Optional Equipment

Certain project-specific options may have been supplied with the
boiler if these options were specified at the time of order entry. In
addition, some options may have been provided (by others) that are
not part of Cleaver-Brooks' scope of supply. In either case, the
Cleaver-Brooks authorized representative should be consulted for
project specifics.
These are the options that are available for the CFC boiler from
Cleaver-Brooks:
A. Dual gas train for quick and easy fuel switchover.
B. Reusable air filter.
C. Condensate neutralization tank assembly - consists of
neutralizing media, filter, and PVC condensate holding tank
with integral drain trap. This assembly is mounted beneath
the boiler and is further described in Chapter 2.
D. Outside air intake for direct vent combustion.
E. Outdoor temperature sensor for indoor/outdoor control.
F. Header temperature sensor for multiple boiler Lead/Lag
operation.
G. Auxiliary Low Water Control (shipped loose) for field piping
by others into the system piping.
H. Alarm Horn for safety shutdown.
I. Relays for output signal for burner on, fuel valve open.
J. Stack Thermometer.
K. Stack temperature limit-sensor.
L. Auto air vent.
M. Boiler drain valve.
