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.

Seal any unused openings in the common venting

system.

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.

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.

Place in operation the appliance being inspected.

Followthelighting/operatinginstructions.Adjust

thermostat so appliance will operate continuously.

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.

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 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:

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.

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.
