GOLD CGi Gas-Fired Water Boiler — Boiler Manual

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.

Direct exhaust venting (Category III) — Do not common vent the CGi in a direct exhaust system (Category III). Connecting more than one appliance to a direct exhaust system will cause flue gas spillage or appliance malfunc- tion, 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 following steps shall be followed with each appliance remaining con- nected to the common venting system placed in operation, while the other appliances remaining 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 condition.

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 connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common 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 summer 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 previous con- ditions 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 re- sizing 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 Instal- lation Code.

Chimney or vent require- ments

1.Venting must be installed according to Part 7, Venting of Equipment, of National Fuel Gas Code, ANSI Z223.1-latest edition and appli- cable building codes. Canadian installations must comply with B149.1 or B149.2 Installation Codes.

2.See Ratings table on page 67 for minimum chim- ney or vent sizes. A chimney or vent without a listed cap should extend at least 3 feet above the highest point where it passes through a roof of a building and at least 2 feet higher than any portion of a building within a horizontal distance of 10 feet. A chimney or vent must not extend less than the distances stated above.

3.A lined chimney is preferred and must be used when required by local, state, provincial and national codes, laws, regulations and ordinances. Vitreous tile linings with joints that prevent retention of moisture and linings made of non- corrosive materials are best. Advice for flue con- nections and chimney linings can be obtained from local gas utility. Type B double-wall metal vent pipe or single-wall vent pipe may be used as a liner.

4.Cold masonry chimneys, also known as outside chimneys, typically have one or more walls ex- posed to outside air. When any atmospheric gas-fired boiler with automatic vent damper is vented through this type of chimney, the potential exists for condensation to occur. Con- densation can damage a masonry chimney. Weil- McLain recommends the following to prevent possible damage.

a.Line chimney with corrosion-resistant metal liner such as AL29-4C® single-wall stainless steel or B-vent. Size liner per Na- tional Fuel Gas Code ANSI Z223.1-latest edition.

b.Provide drain trap to remove any conden- sate.
