A,WARNING

A,CAUTION

G50UH(X) units are CSA International certified to ANSI Z21.47 and CSA 2.3 standard.

In the USA, installation of gas furnaces must conform with local building codes. In the absence of local codes, units must be installed according to the current National Fuel Gas Code (ANSI-Z223.1/NFPA 54). The National Fuel Gas Code is available from the following address:

American National Standards Institute, Inc. 11 West 42nd Street

New York, NY 10036

In Canada, installation must conform with current National Standard of Canada CSA B149 Natural Gas and Propane Installation Codes," local plumbing or waste water codes and other applicable local codes.

Adequate clearance must be made around the air open- ings into the vestibule area. In order to ensure proper unit operation, combustion and ventilation air supply must be

provided according to the current National Fuel Gas Code or CSA B149 standards.

Vent installations must be consistent with the venting tables (in this instruction) and applicable provisions of local building codes.

This furnace is CSA Intemational certified for installation clearances to combustible material as listed on the unit nameplate and in the tables in figures 6 and 11. Accessibility and service clearances must take precedence over fire protection clearances.

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

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 a furnace is installed in a public garage, hangar, or other building that has a haz- ardous atmosphere, the furnace must be installed accord- ing to recommended good practice requirements and cur- rent National Fuel Gas Code or CSA B149 standards.

NOTE - Furnace must be adjusted to obtain a temperature rise within the range specified on the unit nameplate. Failure to do so may cause erratic limit operation.

This G50UH(X) furnace must be installed so that its electri- cal components are protected from water.

When this furnace is used with cooling units, it shall be installed in parallel with, or on the upstream side of, cooling units to avoid condensation in the heating compartment.

With a parallel flow arrangement, a damper (or other means to control the flow of air) must adequately prevent chilled air from entering the furnace. If the damper is manu- ally 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.
