INSTALLATION AND OPERATION INSTRUCTIONS
1-16
DC SERIES BOILERS / WATER HEATERS
DC 15-95, DC 15-96, DC 20-125, DC 33-160
Support should be provided for intake piping, particularly so for horizontal runs
(follow local code).
1.4.8 “Indoor Air” Combustion Air Intake
Using Indoor Combustion Air is not approved for use with the DC series boilers /
water heaters.
1.4.9 Closet Installations
For installations in a confined space (such as a closet), ventilation openings may
be needed through a door or wall to prevent excessive heat from building up
inside the space.
The boiler / water heater shall not be exposed to ambient conditions above 122°F
(50°C) or below 32°F (0°C).
CONDENSATE REMOVAL
IBC’s specified vent configuration promotes the safe drainage of moisture from
the boiler / water heater and exhaust venting without flowing liquids back through
the heat exchanger.
Reliable system operation requires (1) proper design and installation of exhaust
venting to allow condensate to run back to the drain/trap; (2) acid neutralization
as appropriate. To achieve these:
1.
Allow for a 1/4" per foot slope back to the vent connection, with appropriate
hangers to maintain that gradient.
2.
Ensure the supplied trap is correctly installed and filled with water.
3.
When required, add (and maintain in good condition) a neutralization tank.

WARNING
The Trap Hook must be
installed as instructed and all
trap fittings must be tightened
as instructed to prevent
leakage of flue gasses.
Failure to comply may result
in severe personal injury or
death.
WARNING
Fill trap with water before
boiler / water heater is first
fired to prevent exhaust
fumes from entering room.
Never operate the boiler /
water heater unless the trap is
filled with water.
Failure to comply will result
in severe personal injury or
death.
