Locate near a floor drain and in an area where leakage of the tank or water piping will not result in damaging adjacent areas or lower floors of the structure. Where such a location is not available, a suitable drain pan must be installed under this water heater. This pan shall be 1½ “ (40 mm) deep and a diameter that is a minimum of 2" (50 mm) greater than the diameter of the water heater. A suitable pipe properly connected to an adjacent floor drain shall be provided.

This heater may be installed in a closet or alcove and is certified for operation on a combustible floor.

WARNING

Do not install directly on carpet. Instead, place the water heater on a metal or wood panel extending a minimum of 3" (75 mm) from all sides. In alcoves or closets, cover the carpet completely. Ensure that this panel is capable of supporting the weight of this heater when filled with water.

FAILURE TO PROPERLY INSTALL THIS HEATER MAY RESULT IN A FIRE HAZARD.

II)AIR REQUIREMENTS

General.

ØAn adequate air supply shall be provided for combustion and ventilation of this water heater. An insufficient supply can result in poor combustion and possible sooting of the burner, combustion chamber or flue passageway. This may present a potential fire hazard or could create a serious health hazard by producing carbon monoxide.

Where an exhaust fan or any other air consuming appliance (Eg. Clothes dryer, furnace, etc.) is installed in the same space as the water heater, sufficient air openings must be available to provide fresh air when all appliances are operating simultaneously.

The area in which the heater is located is classified as either “an unconfined space” or “a confined space.”

An unconfined space is defined as a space having a volume not less than 50 cubic feet per 1000 BTU/hour (4.8 cubic meters per kilowatt) of combined input rating of all appliances using the space. Adjacent open rooms may be included as part of the unconfined space. There shall be no closeable doors between these rooms. An example of this is an open basement.

Aconfined space is one smaller than described above. Air shall be supplied through permanent openings as described in Figures 3 and 4. At no time shall an air opening have a dimension of less than 3" (75 mm) and at no time shall any top opening be lower than the top of the water heater.

For buildings that are not well sealed (do not have tight fitting doors and windows) natural air infiltration may provide sufficient air required for combustion and ventilation. For buildings using tight construction (newer and renovated structures), the air supply shall be introduced from the outdoors, regardless of whether the space is confined or unconfined.

Combustion Air “Supply” Ducts

Air supply ducts shall be of galvanized steel or equivalent corrosion resistant material. A single air duct may not be substituted when required for upper and lower air openings.

Horizontal upper combustion air ducts shall not slope downward toward the air inlet.

Louvers and Grills

Openings for air supply ducts must provide free unobstructed air movement. Louver and grill openings must be sized to ensure that the FREE OPEN AREA is never less than the area of the air duct.
