Introduction and Unpacking
1.1 General Instructions
It is important for you to take a few minutes to
review this Installation and Operating Instructions
manual before you begin installation. This will make
installing and operating the unit easier and faster.
Direct vent-sealed combustion:
The 9600 CB boiler does not and should not take
combustion air from inside the building. All of the air
is drawn in from outdoors through a 3-inch diameter
plastic pipe. 3" PVC, ABS or CPVC pipe is used for
air intake and exhaust venting. (PVC, ABS not
permitted for CB-M2-250 exhaust).
No chimney....flue....or draft inducer required.
Because this is a sealed combustion, forced draft unit,
it does not require, and must not be connected to a
chimney, existing venting system, or draft inducer.
Caution
Connection of this vent to a chimney, existing venting
system, or draft inducer will result in poor and possibly
dangerous operation.
The supplied vent terminations are designed to
be installed through the nearest outside wall.
The CB boiler is protected against over
pressurization. A 50 PSI pressure relief valve is fitted
to all units and a 125 PSI valve is optional. It is
installed in the dedicated fitting on the back of the
boiler.
IMPORTANT: The inlet gas pressure to the appliance
must not exceed 13" WC.
A high quality circulator is built into the CB
boiler and will provide sufficient head to circulate
water to the supply and return headers. An external
circulator is required to circulate water to and from
baseboard or fan coil units (secondary loop).
All installations must be made in accordance
with the 1). American National Standard Z223.1-
Latest Edition “National Fuel Gas Code” or 2). CSA
B149.1 "Installation Codes for Gas Burning
Appliances and Equipment" and with the requirement
of the local utility or other authorities having
jurisdiction. Such applicable requirements take
precedence over the general instructions contained
herein.
All electrical wiring is to be done in accordance
with the local codes, or in the absence of local codes,
with: 1). The National Electrical Code ANSI/NFPA
No. 70-latest Edition, or 2). CSA STD. C22.1
"Canadian Electrical Code - Part 1". This appliance
must be electrically grounded in accordance with
these codes. Where required by the authority having
jurisdiction, the installation must conform to the
Standard for Controls and Safety Devices for
a. Total combined feet allowed for intake and
exhaust vent pipe per instructions. The following
are acceptable materials for intake and exhaust
vents:
b. Electrical connection to a 120VAC/15Amp
service.
c. Gas connection that will provide 250 cubic feet/
hour at 4 to 13 inch water gauge pressure.
d. Condensate drainage: a floor drain is preferred, a
condensate pump can be used if required.
e. Miscellaneous copper fittings and bronze valves
will be required to complete the piping system.
