Hazard definitions 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.

1. Please — read before proceeding . . . . .

To the installer 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.

Venting method

definitions 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.)

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.

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.

2. Determine venting method

Direct exhaust ventingDirect exhaust venting

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

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).

1. Sidewall direct exhaust venting

— using vent manufacturer’s termination fittings

listed in this supplement. See Figure 1.

Direct vent methodsDirect vent methods

Direct vent methods

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

3. Combustion air supply —

eliminate contamination

Table 1 Corrosive contaminants

To prevent potential of severe

personal injury or death, check for

areas and products listed below

before installing boiler. If found:

•remove products permanently

— OR —

•provide outside combustion air

(direct vent installation).

Please review the following information on potential

combustion air contamination problems.

Refer to Table 1 for products and areas that may cause

contaminated combustion air. These contaminants may

cause damage to the vent piping, and must be eliminated

If the boiler is installed in any area likely to cause

contamination, or if products which would

contaminate the air cannot be removed, you must pipe

combustion air to the boiler air intake. Contaminated

combustion air will damage the boiler, resulting in

possible severe personal injury, death or substantial

property damage. Do not install a CGs boiler in a

laundry room or pool facility, for example, without

using ducted outside air. These areas will always contain

contaminants.

from the boiler combustion air supply.You may do this

by removing the contaminants permanently from the

area or piping air directly to the boiler (direct vent) using

one of the methods referenced in this supplement and

described in the direct vent supplements.

Products to avoid Areas likely to have contaminants

Spray cans containing chloro/fluorocarbons Dry cleaning/laundry areas and establishments

Permanent wave solutions Swimming pools

Chlorinated waxes/cleaners Metal fabrication plants

Chlorine-based swimming pool chemicals Beauty shops

Calcium chloride used for thawing Refrigeration repair shops

Sodium chloride used for water softening Photo processing plants

Refrigerant leaks Auto body shops

Paint or varnish removers Plastic manufacturing plants

Hydrochloric acid/muriatic acid Furniture refinishing areas and establishments

Cements and glues New building construction

Antistatic fabric softeners used in clothes

dryers Remodeling areas

Chlorine-type bleaches, detergents, and clean-

ing solvents found in household laundry rooms Garages with workshops

Adhesives used to fasten building products and

other similar products

The following special gas vent systems comply with UL-1738 and ULC-

S636 standards and are certified by CSA as the only systems suitable for

use with CGs boilers:

• Heat-Fab, Inc. Saf-T Vent®

• Flex-L International, Inc. StaR-34

• Z-Flex®, Inc. Z-Vent II

•ProTechSystemsFasNSeal™

Use only the vent starter of the same manufacturer as the vent compo-

nents. Do not mix components from different systems. The vent system

could fail, causing flue gas spillage, resulting in severe personal injury or

death.

4. Obtain vent system components

1. The

Through-Roof or Through-Unused-Chimney Termination Kit

provides special parts required to route 3-inch stainless vent pipe

through 5-inch B-vent. The space between the vents provides the

passage for combustion air. See page 9 for parts included with the kit.

2. Verify that the vent termination will comply with the requirements

listed on page 11. Then verify that the vent and air piping will not

exceed the length limits given in section 8 of this supplement before

locating boiler or floor/roof penetrations.

3. You will need to obtain stainless vent pipe and fittings, using only the

vent systems listed in the CGi, CGs & GV Vent Component

Supplement. Also obtain B-vent pipe and fittings for the vertical run

and floor/roof penetrations (See Table 3).

4. Use suitable 3" material for combustion air connector piping, such as:

• Dryer vent

• Galvanized steel

• PVC (3" I.D.)

1. Select a vent pipe manufacturer and obtain all vent

components needed, based on boiler location and

venting method.

2. You must use the vent starter made by the vent pipe

manufacturer. See separate CGi, CGs & GV Vent

Component Supplement, for part numbers of each

component, listed by vent manufacturer.

Use only the vent starter of the same

manufacturer as the vent compo-

nents. Do not mix components from

different systems. The vent system

could fail, causing flue gas spillage,

resulting in severe personal injury or

death.

3. Follow all applicable national, state, local or

provincial codes when venting the CGs boiler.

4. Connect vent starter to blower housing outlet as

shown in the Figures 7 through 10, below.

a. Do not mix components from different vent

manufacturers.

b. Maintain minimum 2" clearance from

combustible materials to vent pipe.

c. Seal with sealant specified by vent pipe

manufacturer, using ³⁄₈" bead (not required for

FasNSeal™).

d. Tighten strap at band clamp screw until strap is

snug around blower housing.
