CGs-4E Gas-Fired Water Boiler — Boiler Manual
Prepare boiler location — vent system1c
Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe
personal injury or death.
When removing boiler from an
existing common vent system:
Atthetimeofremovalofanexistingboiler,thefol-
lowing steps shall be followed with each appliance
remaining connected to the common venting system
placed in operation, while the other appliances remain-
ing connected to the common venting system are not
in operation.
a.
Seal any unused openings in the common venting
system.
b.
Visually inspect the venting system for proper
size and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion or other
deficiencies which could cause an unsafe condi-
tion.
c.
Test vent system — Insofar as is practical, close all
building doors and windows and all doors between
the space in which the appliances remaining con-
nected to the common venting system are located
and other spaces of the building. Turn on clothes
dryers and any appliance not connected to the com-
mon venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they will
operateatmaximumspeed.Donotoperateasum-
merexhaustfan.Closereplacedampers.
d.
Place in operation the appliance being inspected.
Followthelighting/operatinginstructions.Adjust
thermostat so appliance will operate continuously.
e.
Test for spillage at draft hood relief opening after
5 minutes of main burner operation. Use the flame
of a match or candle.
f. Afterithasbeendeterminedthat
each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers,
and any other gas-burning appliance to their previ-
ous conditions of use.
Anyimproperoperationofcommonventingsystem
should be corrected so the installation conforms with
theNationalFuelGasCode,ANSIZ223.1-latestedition.

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

sembly.TheCGsventstarterisaspecialitem,designed

vendor.DonotattempttoconnecttheventtotheCGs-
4Eboilerwithanyothermeans.
DO NOT mix components from
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
ALWAYS terminate
at the same location as the flue, using either:
1.
Vertical direct vent installation. Obtain the
Weil-McLainThrough-Roof or Through-Unused
Chimney
termination kit and supplement. Refer
to Vertical Direct VentingVentingSupplement,
packed with the kit, and to the vent manufacturer’s
instructions for the vent material chosen.
2.
Sidewall direct vent installation. Use the Vent/Air
Intake
termination kit shipped with the boiler. Refer
to CGs Direct Venting: Sidewall & Direct Exhaust
Venting: Vertical or Sidewall
VentingSupplement
shipped with the boiler.
DO NOT COMMON VENT—DonotinstalltheCGs-4Eintoacommonventwithanyotherappliance.Thiswill
cause flue gas spillage or appliance malfunction, resulting in possible severe personal injury, death or substantial
property damage.
Inspect existing chimney before installing boiler. Failure to clean or replace perforated pipe or tile lining will cause
severe personal injury or death.
