Combustion air supply, Corrosive contaminants

GOLD GV Water boiler — Series 3

Combustion air supply

Special note Refer to GV Series 3 Boiler Manual for sizing free area of combustion/ventilation air openings.

All boilers experience some condensation in section assembly during start-up. Unlike most conventional boilers, condensation is minimized in the GV Series 3 Boiler by a built-in mixing system, maintaining boiler return water temperature above 130 0F, during steady state operation.

Flue gas condensate is slightly acidic. In most cases pH level is not harmful to vents or drains. When combustion air is contaminated by vapors from products and areas, listed in Table 1 below, condensate acidic levels increase. Higher acidic levels attack many materials, including stainless steel commonly used in high efficiency systems.

You may choose to use outside combustion air for any of the following reasons:

•Installation is in an area containing contaminants listed in Table 1 below, which will induce acidic contamination.

•You want to reduce infiltration into your home through openings around windows and doors.
