Part No. 750-263 2-9
B.FLUE GAS / COMBUSTION AIR CONNECTIONS
The high efficiency of the CFC boiler may cause water vapor to
condense out of the flue gases.
The flue gases from the Model CFC boiler should be removed via a
gas-tight, temperature and corrosion resistant flue gas pipeline.
Only flue gas systems approved and tested by the relevant region or
province are to be connected to the boiler. Refer to flue piping
manufacturer for proper installation and sealing instructions. See
also Chapter 4 of this manual for combustion air and flue gas
venting requirements.
C.WATER TREATMENT
The Model CFC boiler is designed to operate with water chemistry
ranging from a pH value of 8.3 to 9.5 with maximum permissible
oxygen content of 7 ppb. For values outside this range contact your
Cleaver-Brooks representative for assistance.
Corrosion and sludge deposits in old systems must be removed prior
to installation of a new boiler.

D.BOILER ROOM
The boiler room must comply with all building codes and
regulations. An adequate supply of combustion air is required for
safe operation. If the optional direct vent combustion air kit (Figure
2-8) is not used, ventilation must be provided to meet applicable
regulations for air supply.
See Section 6, Parts, for part numbers for the Direct Vent
Combustion Air kits available.
