Adams Condensing Oil-Fired Furnace operation manual Clearances and Accessibility

Follow the instructions listed below when selecting a furnace location.

Refer also to the guidelines provided in Section V. Combustion and Ventilation Air Requirements.

oCentrally locate the furnace with respect to the proposed or existing air distribution system.

oEnsure the temperature of the return air entering the furnace is between 55 F and 90 F when the furnace is heating.

oProvide provisions for venting combustion products outdoors through a proper venting system. Special consideration should be given to ventlflue pipe routing and combustion air intake pipe when applicable. Refer to Section IX, Vent/Flue Pipe and Combustion Air Pipe Termination Locations for appropriate termination locations and to determine if the piping system from furnace to termination can be accomplished within the guidelines given.

oNOTE: The length of flue and/or combustion air piping can be a limiting factor in the location of the furnace.

oLocate the furnace so condensate flows downwards to the drain. 00 not locate the furnace or its condensate drainage system in any area subject to below freezing temperatures without proper freeze protection. Refer to Section X. Condensate Drain Lines and Trap for further details.

oEnsure adequate combustion air is available for the furnace. Improper or insufficient combustion air can expose building occupants to combustion products that could include carbon monoxide. Refer to Section V., Combustion and Ventilation Air Requirements.

oSet the furnace on a level floor to enable proper condensate drainage. If the floor becomes wet or damp at times, place the furnace above the floor on a concrete base sized approximately 1-1/2 times larger than the base of the furnace.

Exposure to contaminated combustion air will result in safety and performance related problems. 00 not install the furnace where the combustion air is exposed to the following substances:

Chlorinated waxes or cleaners Chlorine-based swimming pool chemicals Water softening chemicals

Deicing salts or chemicals Carbon tetrachloride Halogen type refrigerants Cleaning solutions (such as

perchloroethylene Printing inks Paint removers Vanishes Hydrochloric acid Cements and glues

Antistatic fabric softeners for clothes dryers.

Masonry acid washing materials

oSeal off a non-direct vent furnace if it is installed near an area frequently contaminated by any of the above substances. This protects the non-direct vent furnace from airborne contaminants. To ensure that the enclosed non-direct vent furnace has an adequate supply of combustion air, vent from a nearby uncontaminated room or from outdoors. Refer to the Section V. combustion and Ventilation Air ReqUirements for details.

oIf the furnace is used in connection with a cooling unit, install the furnace upstream or in parallel with a cooling unit. Premature heat exchanger failure will result if the cooling unit is placed ahead of the furnace.

oIf the furnace is installed in a residential garage, position the furnace so that the burner and ignition source are located not less than 18 inches (457 mm) above the floor. Protect the furnace from physical damage by vehicles.

Clearances and Accessibility

Installations must adhere to the clearances to combustible materials to which this furnace has been design certified. The minimum clearance information for this furnace is provided on the units rating label.
