GS110 DIRECT VENT BOILER INSTALLATION AND OPERATION INSTRUCTIONS

COMBUSTION AIR & VENTILATION

WARNING: This boiler must be supplied with combustion air in accordance with Section 5.3, Air for Combustion & Ventilation, of the latest revision of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and all applicable local building codes. Canadian installations must comply with CSA B149.1 or .2 Installation Code for Gas Burning Appliances and Equipment, or applicable provisions of the local building codes. Failure to provide adequate combustion air for this boiler/water heater can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

To operate properly and safely this boiler requires a continuous supply of air for combustion. NEVER store objects on or around the boiler!

CAUTION: Combustion air contaminated with fluorocarbons or other halogenated compounds such as cleaning solvents and refrigerants will result in the formation of acids in the combustion chamber. These acids will cause premature failure of the boiler voiding the warranty!

CAUTION: If the boiler is operated while the building is under construction it MUST be protected from wood, concrete, sheet rock and other types of dust. Failure to properly protect the unit from construction dust will damage the unit voiding the warranty!

Buildings may require the installation of a fresh air duct or other means of providing make-up air if the intake air option isn't used. Any building utilizing other gas burning appliances, a fireplace, wood stove or any type of exhaust fan must be checked for adequate combustion air when all of these devices are in operation at one time. Sizing of an outside air duct must be done to meet the requirements of all such devices.

WARNING: Never operate this boiler in an environment subjected to a negative pressure unless the air intake is connected to the outdoors. Failure to comply with this warning can result in excessive levels of carbon monoxide causing severe personal injury or death!

All Combustion Air From Inside The Building

Older houses often have enough “leakage” to provide an adequate amount of combustion air provided that the demand for combustion air is not too great, Figure 3. Homes that are relatively new or “tight” will most likely require that the combustion be ducted to the boiler from outside the building. Any home utilizing other gas burning appliances, a fireplace, wood stove or any type of exhaust fan must be checked for adequate combustion air when all of these devices are in operation at one time.

If the boiler is to be located in an alcove, closet or other confined space the distances from the boiler and it's vent system to all-combustible construction must be equal to or greater than the minimum clearances in Figure 1. When installed in a closet or confined space two permanent openings of equal area adjoining another room or rooms having sufficient volume to meet the requirements of an unconfined space must be provided, Figures 4 & 5. Each opening must have a minimum free area of one square inch per 1000 Btu/hr (2200 mm2/ kW) based on the total input rating of all gas utilization equipment in the confined area. Each opening must be no less than 100 square inches (64516 mm2) in size. The upper opening must be within 12 inches (305 mm) of, but not less than 3 inches (76 mm) from, the top of the enclosure. The bottom opening must be within 12 inches (305 mm) of, but not less than 3 inches (76 mm) from, the bottom of the enclosure.

All Combustion Air From Outside The Building When installed in a confined space without the intake air option two permanent openings communicating directly with, or by ducts to, the outdoors or spaces that freely communicate with the outdoors must be present. The upper opening must be within 12 inches (305 mm) of, but not less than 3 inches (76 mm) from, the top of the enclosure. The bottom opening must be within 12 inches (305 mm) of, but not less than 3 inches (76 mm) from, the bottom of the enclosure.

Where directly communicating with the outdoors or communicating with the outdoors through vertical ducts, each opening shall have a minimum free area of 1 in2/ 4000 Btu/hr (550 mm2/kW) of the total input rating of all of the equipment in the enclosure.

Where communicating with the outdoors through hori- zontal ducts, each opening shall have a minimum free area of 1 in2/2000 Btu/hr (1100 mm2/kW) of the total input rating of all of the equipment in the enclosure.

When ducts are used, they must have the same cross- sectional area as the free area of the opening to which they connect. Sizing of an outside air duct must be based on the total input rating of all gas utilization equipment in the confined space.
