Be careful when you handle this only the type of gas approved for use with this to unit CodesIn the USA, INSTALLATION of gas furnaces must conform with lo-cal building codes.

8 In the absence of local codes, units mustbe installed according to the current National Fuel Gas Code( 54). The National Fuel Gas Code isavailable from the following address:American National Standards Institute, West 42nd StreetNew York, NY 10036 Installed LocationsIn Canada, INSTALLATION must conform with current NationalStandard of Canada CSA-B149 Natural Gas and PropaneInstallation Codes, local plumbing or waste water codesand other applicable local furnace is designed for INSTALLATION clearances to com-bustible material as listed on the unit nameplate and in thetables in figures 10 and 11. Accessibility and service clear-ances must take precedence over fire protection For INSTALLATION on combustible floors, the furnaceshall not be installed directly on carpeting, tile, or othercombustible material other than wood INSTALLATION in a residential garage, the furnace mustbe installed so that the burner(s) and the ignition sourceare located no less than 18 inches (457 mm) above thefloor.

9 The furnace must be located or protected to avoidphysical damage by vehicles. When a furnace is installedPage 5in 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 NOTE Furnace must be adjusted to obtain a tem-perature rise (100% percent capacity) within the range(s)specified on the unit nameplate. Failure to do so may causeerratic limit operation and may also result in premature heatexchanger SLP98 UHV furnace must be installed so that its elec-trical components are protected from in Combination with a Cooling CoilWhen this furnace is used with cooling units, it shall beinstalled in parallel with, or on the upstream side of, coolingunits to avoid condensation in the heating a parallel flow arrangement, a damper (or other meansto control the flow of air) must adequately prevent chilled airfrom entering the furnace.

10 If the damper is manually oper-ated, it must be equipped to prevent operation of either theheating or the cooling unit, unless it is in the full HEAT orCOOL setting.
