CGs-4E special vent system
Vent system
The CGs-4E boiler requires a special vent system, de-
signed for pressurized venting. Model CGs-4E is rated
ANSI Z21.13
Category IV
(pressurized vent, likely to
condense in the vent).
You may use any of the vent systems covered by the
CGs Venting Supplements included in the envelope as-
sembly. The CGs vent starter is a special item, designed
only for CGs and CGs-4E boilers, available from each
vendor. Do not attempt to connect the vent to the CGs-
4E boiler with any other means.
DO NOT
different systems. The vent system
could fail, causing leakage of flue
products into the living space.
Vent termination and combustion air
supply
The CGs-4E boiler may be vented through the roof or
through a side wall. Follow the appropriate vent supple-
ment for the vent system chosen. The maximum vent
length depends on boiler size. Refer to the vent supple-
ment to determine acceptable vent length.
Combustion air for the CGs-4E boiler must be ducted
directly to the boiler from outside. For outside air (direct
vent installation), two options are available for the flue/
air termination. The air supply must
at the same location as the flue, using either:
