1c Prepare boiler location — vent system

Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.

Inspect existing chimney before installing boiler. Failure to clean or replace perforated pipe or tile lining will cause severe personal injury or death.

DO NOT COMMON VENT — Do not install the CGs 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.

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 fireplace 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. Correct by resizing to approach the minimum size as determined using the appropriate tables in Part 11 of that code. Canadian installations must comply with B149.1 or B149.2 Installation Code.

CGs special vent system

Vent system

The CGs boiler requires a special vent system, designed for pressurized venting. Model CGs-3 is rated ANSI Z21.13 Category IV (pressurized vent, likely to condense in the vent). Models CGs-4, -5 and -6 are rated Z21.13 Category III (pressurized 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 the CGs boiler, available from each vendor. Do not attempt to connect the vent to the CGs 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 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 boiler may be from in- side or 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 DirectVenting: Sidewall & Direct Exhaust Venting:Vertical or Sidewall Venting Supplement shipped with the boiler.
