These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, salts, air fresheners, and other household products. Humidifier warranty is voided when failure of gas equipment is due to operation in a corrosive atmosphere. - Page 11 The outdoor air source can be a connection outside the building or a connection to an outdoor air plenum inside the building. If the inlet combustion air is to be drawn in from a connection outside the building, special precautions must be made, such as proper termination outside the wall, and a screen on the air inlet to prevent any debris from entering the air inlet pipe.

Page 12: Venting (General)
Venting Overview - This humidifier is a Category I / III appliance, which means it produces a positive pressure in the vent system when it is exhausting the appliance flue products to the outdoors. It may be vented vertical or horizontal but special flue pipe must be used which is listed for Category I / III appliances for horizontal piping. -
