Clearances and Accessibility

NOTE: For servicing or cleaning, a 24” front 

clearance is required. Unit connections 

(electrical, flue and drain) may necessitate 

greater clearances than the minimum clearances 

listed above.

NOTE: In all cases, accessibility clearance must 

take precedence over clearances from the 

enclosure where accessibility clearances are 

greater.

NOTE: 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 

unit’s clearance label.  These clearances must be 

permanently maintained.  Clearances must also 

accommodate an installation’s gas, electrical, 

and drain trap and drain line connections.  If 

the alternate combustion air intake or vent/flue 

connections are used additional clearance must 

be provided to accommodate these connections.  

Refer to 

Vent/Flue Pipe and Combustion Air Pipe

 for 

details.

•   Isolate 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 

Combustion and Ventilation Air Requirements

 for 

details.

•   If the furnace is used in connection with a cooling coil 

unit, install the furnace upstream or in parallel with the 

cooling coil unit.  Premature heat exchanger failure 

will result if the cooling unit is placed ahead of the 

furnace. 

• 

  For vertical (upflow or downflow) applications, the 

minimum cooling coil width shall not be less than 

furnace width minus 1”.  Additionally, a coil installed 

above an upflow furnace or under a counterflow 

furnace may be the same width as the furnace or may 

be one size larger than the furnace.  

 

Example: a “C” width coil may be installed with 

 

a “B” width furnace.

For upflow applications, the front of the coil and furnace 

must face the same direction.

•   If the furnace is installed in a residential garage, 

position the furnace so that the burners and ignition 

source are located not less than 18 inches (457 mm) 

above the floor.  Protect the furnace from physical 

damage by vehicles.

•   If the furnace is installed horizontally, ensure the 

access doors are not on the “up/top” or “down/bottom” 

side of the furnace.

• 

  Do not connect this furnace to a chimney flue that 

serves a separate appliance designed to burn solid 

fuel. 

• 

  On Counterflow Installations, the air conditioning coil 

must be downstream on the supply (positive) side of 

the furnace heat exchanger.

•  

Counterflow Installation over a noncombustible floor. 

Before setting the furnace over the plenum opening, 

ensure the surface around the opening is smooth 

and level. A tight seal should be made between the 

furnace base and floor by using a silicone rubber 

caulking compound or cement grout.

•  

Counterflow Installation over a combustible floor. 

If installation over a combustible floor becomes 

necessary, use an accessory subbase (see 

Specification Sheet applicable for your model for 

details.)  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. Follow the 

instructions with the subbase for proper installation. 

Do not install the furnace directly on carpeting, tile, or 

other combustible material other than wood flooring. 

NOTE: A subbase will not be required if an air 

conditioning coil is installed between the supply 

air opening on the furnace and the floor.)
