Maytag Amana CVC96 BA Series, Installation Instructions Manual

Refer to 

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.  

NOTE:

  The length of flue and/

or combustion air piping can be a limiting factor in the 

location of the furnace. 

• 

  Locate the furnace so condensate flows downwards 

to the drain.  Do not locate the furnace or its 

condensate drainage system in any area subject to 

below freezing temperatures without proper freeze 

protection. Refer to

 Condensate Drain Lines and Trap

for further details.

•   Ensure adequate combustion air is available for the 

furnace.  Improper or insufficient combustion air 

can expose building occupants to gas combustion 

products that could include carbon monoxide.  Refer 

to 

 Combustion and Ventilation Air Requirements.

• 

  Set 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” larger 

than the base of the furnace.  Refer to the 

Horizontal 

Applications and Considerations

 for leveling of 

horizontal furnaces.

• 

  Ensure upflow or horizontal furnaces are not installed 

directly on carpeting, or any other combustible 

material.  The only combustible material allowed is 

wood.

•   A special accessory subbase must be used for upright 

counterflow unit installations over any combustible 

material (including wood).  Refer to subbase 

instructions for installation details.  (

NOTE:

 A subbase 

will not be required if an air conditioning coil is located 

beneath the furnace between the supply air opening 

and the combustible floor.

•   Exposure to contaminated combustion air will result 

in safety and performance-related problems.  Do 

not install the furnace where the combustion air is 

exposed to the following substances: 

- permanent wave solutions                    

- cleaning solutions (such as perchloroethylene)

- printing inks                                      

- chlorinated waxes or cleaners

- paint removers 

- chlorine-based swimming pool chemicals

- varnishes 

- water softening chemicals 

- hydrochloric acid  

- carbon tetrachloride 

- cements and glues 

-deicing salts or chemicals 

- halogen type refrigerants 

-  antistatic  fabric  softeners  for  clothes  dryers                                                   

- masonry acid washing materials

The rated heating capacity of the furnace should be greater 

than or equal to the total heat loss of the area to be heated.  

The total heat loss should be calculated by an approved 

method or in accordance with “ASHRAE Guide” or “Manual 

J-Load Calculations” published by the Air Conditioning 

Contractors of America.

•   Centrally locate the furnace with respect to the 

proposed or existing air distribution system.

•   Ensure the temperature of the return air entering the 

furnace is between 55°F and 100°F when the furnace 

is heating.

•   Provide provisions for venting combustion products 

outdoors through a proper venting system.  Special 

consideration should be given to vent/flue pipe routing 

and combustion air intake pipe when applicable.
