NOTE - For installation on combustiblefleers, the furnace shaft not be installed directly on carpeting, tile, or other combustible material other than wood flooring.

Accessibility and service clearances must take prece- dence over fire protectionclearances.

For installation in a residential garage, the furnace must be installed so that the burner(s) and the ignition source are located no less than 18 inches (457 mm) above the floor. The furnace must be located or protected to avoid physical damage by vehicles. When e furnace is installed in a public garage, hangar, or other building that has a hazardous atmosphere,the fumace mustbe installed ac- cording to recommended good practice requirements and current National Fuel Gas Code or CAN/CGA B149.1 and B149.2 standards.

When the furnace is used with cooling units, it shall be installed in parallel with, or on the upstream side of. cool- ing units to avoid condensation in the heating compart- ment. With a parallel flow arrangement, a damper (or oth- er means to control the flow of air) must adequately prevent chilled air from entering the furnace. If the damp- er is manually operated, it must be equipped to prevent operation of either the heating or the cooling unit, unless it is in the full =HEAT" or "COOL" setting.

When installed, the furnace must be electrically grounded according to local codes. In addition, in the United States, installation must conform with the current National Elec- tric Code, ANSI/NFPA No. 70. The National Electric Code

(ANSI/NFPA No. 70) is available from the following ad- dress:

In Canada, all electrical wiring and grounding for the unit must be installed according to the current regulations of the Canadian Electrical Code Part I (CSA Standard C22.1 ) and/or local codes.

Field widng connections must meet or exceed specifica- tions of type T wire and withstand a maximum tempera- ture dee of 180°F (82°C).

G32 unit must be installed so that electrical components are protected from water.

When the furnace is installed so that supply ducts carry air circulated by the furnace to areas outside of the space containing the furnace, return air shall be handled by a duct(s) sealed to the furnace casing and terminating out- side space containing furnace.
