Hazard definitions
Venting method definitions
To the installer
The following terms are used throughout this Venting Supplement to bring attention to the presence of hazards of various risk levels or to important information concerning the life of the product.
Indicates presence of hazards that will cause severe personal injury, death or substantial property damage.
Indicates presence of hazards that can cause severe personal injury, death or substantial property damage.
Indicates presence of hazards that will or can cause minor personal injury or property damage.
Indicates special instructions on installation, operation or maintenance that are important but not related to personal injury or property damage.
Direct vent — Uses outside combustion air with combustion air connector piping sealed at all joints and seams. Also known as sealed combustion. All CGs flue gas vents are pressurized, requiring careful sealing of all joints. See also CGs Venting Supplement — Direct Vent: Sidewall & Direct Exhaust: Vertical and Sidewall for alternate direct vent method.
Direct exhaust venting — Uses inside combustion air with no combustion air connector piping. All CGs flue gas vents are pressurized, requiring careful sealing of all joints. Also known as non-direct venting. See CGs Venting
Supplement — Direct Vent: Sidewall & Direct Exhaust: Vertical and Sidewall venting supplement for application information.
Chimney draft vent — Uses the natural draft provided by a vertical vent or chimney. (This method cannot be used with CGs boilers.)
Chimney draft venting cannot be used for CGs boilers. Vent system must be constructed only using venting materials listed in this Venting Supplement. Existing vertical vents or chimneys may only be used as raceways for routing vent or vent/air piping as described in this supplement or CGs Direct Vent Supplements.
Boiler must be vented and supplied with combustion air as described in this supplement. Failure to do so will result in severe personal injury, death or substantial property damage.
Use only the sealant specified by the vent pipe manufacturer, applied per their instructions. Vent piping must be sealed gas-tight to prevent possibility of flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.
Provide combustion and ventilation air openings as described in the CGs Boiler Manual and this supplement. Failure to provide adequate air supply could result in severe personal injury, death or substantial property damage.

2. Determine venting method
To prevent potential of severe personal injury or death, check for areas and products listed on page 6 before installing boiler. If found:
•remove products permanently
—OR —
•provide outside combustion air (direct vent installation).
Direct exhaust venting
Use only when openings for inside combustion air can be supplied in accordance with the CGs Boiler manual, this venting supplement and with all applicable codes.
You must direct vent the boiler if the boiler area may contain contaminants as described in this supplement.
Two direct exhaust vent options are permitted: sidewall and vertical, per instructions in CGs Direct Venting:
Sidewall & Direct ExhaustVenting:Vertical or Sidewall
Venting Supplement.

1. Sidewall direct exhaust venting
— using vent manufacturer’s termination fittings listed in this supplement. See Figure 1.
See instructions on pages 6, 7, 8, 9 and 10 – 13.
87251 |
2. Vertical direct exhaust venting
— using penetration through roof or using existing unused chimney or vent as raceway for vent pipe. See Figure 2.

Direct vent methods
Figure 4 Typical vertical direct vent installation
Combustion air is provided by air piping connecting from the boiler Air intake fitting to the outside.
You must direct vent the boiler (pipe outside air to boiler air intake fitting) if the boiler area may contain contaminants as described in this supplement.
Two direct vent options are permitted:
1.Sidewall direct vent
—using Weil-McLain Vent/Air IntakeTermination Kit. See instructions in CGs Direct Vent: Sidewall & Direct Exhaust: Vertical or Sidewall Venting Supplement. Termination kit is included with CGs boiler. See Figure 3.
2.Vertical direct vent
—using Weil-McLain Through-Roof orThrough- Unused-ChimneyTermination Kit. Instructions for vertical direct venting are covered in this supplement. See Figure 4.
