COMBUSTION AIR

WARNING: This boiler must be supplied with combustion air in accordance with Section 5.3, Air for Combustion & Ventilation, of the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and all applicable local building codes. Failure to provide adequate combustion air for this appliance 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. Oxygen is used by the burners in the boiler to burn the gas. An adequate supply of outside air must be available to replace the air used by this process.

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. Homes that are relatively new or “tight” will most likely require the installation of a fresh air duct or other means of providing air for combustion. 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. Sizing of an outside air duct must be done to meet the requirements of all such devices, see Table 2.

COMMON VENT SYSTEMS

WARNING: Do not connect this boiler or any other appliance using a mechanical draft system under positive pressure to a common vent system! Failure to comply with this warning could result in the accumulation of carbon monoxide gas which can cause severe personal injury or death!

If an existing appliance is removed from a common venting system, the common venting system may then be too large for the proper venting of the remaining appliances connected to it. At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, one at a time, while the other appliances remaining connected to the common venting system are not in operation.

Au moment du retrait d’une chaudière existante, les mesures suivantes doivent être prises pour chaque appareil toujours raccordé au système d’évacuation commun et qui fonctionne alors que d’autres appareils toujours raccordés au système d’évacuation ne fonction-nent pas: système d’évacuation.

1.Seal any unused openings in the common vent system.

Sceller toutes les ouvertures non utilisées du sys-tème d’évacuation.

2.Visually inspect the venting system for proper size and horizonal pitch and determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

Inspecter de façon visuelle le système d’évacu-ation pour déterminer la grosser et l’inclinaison horizontale qui conviennent et s’assurer que le système est exempt d’obstruction, d’étranglement de fruite, de corrosion et autres défaillances qui pourraient présenter des risques.
