If contaminating chemicals will be present near the location of the boiler combustion air inlet, have your installer pipe the boiler combustion air and vent to another location, per this manual.

products to the outside while using combustion air from the equipment room. In order to use the room air venting option the following conditions and considerations must be followed.

•The unit MUST be installed with the appropriate room air kit (Table 3D).

•The equipment room MUST be provided with properly sized openings to assure adequate combustion air. Please refer to instructions provided with the room air kit.

•There will be a noticeable increase in the noise level during normal operation from the inlet air opening.

•Using the room air kit makes the unit vulnerable to combustion air contamination from within the building. Please review Section 1, Prevent Combustion Air Contamination, to ensure proper installation.

•Vent system and terminations must comply with the standard venting instructions set forth in this manual.

￿WARNING

￿WARNING

If the boiler combustion air inlet is located in a laundry room or pool facility, for example, these areas will always contain hazardous contaminants.

Pool and laundry products and common household and hobby products often contain fluorine or chlorine compounds. When these chemicals pass through the boiler, they can form strong acids. The acid can eat through the boiler wall, causing serious damage and presenting a possible threat of flue gas spillage or boiler water leakage into the building.
