INSTALLER’S GUIDE

WARNING

!

Do NOT install the filter in the return duct directly 

above the furnace in horizontal applications. Install 

the filter remotely. Installing the filter directly 

above the furnace in horizontal applications may 

cause property damage, serious injury or death.

WARNING

!

TO PREVENT INJURY OR DEATH DUE TO CONTACT 

WITH MOVING PARTS, TURN THE POWER TO THE 

FURNACE OFF BEFORE SERVICING FILTERS.

When the upflow furnace is installed in the horizontal right 

or left application and a close coupled (less than 36") return 

duct is attached to the bottom side of the furnace as shown 

in Figure 12, securely attach a 1/2" mesh metal hardware 

cloth protective screen to the inside bottom of the filter grill 

to prevent personal injury from contacting moving parts 

when reaching into the return opening to replace the 

filter.

FILTER

REMOVE FILTER FROM UPFLOW 

FURNACE WHEN RETURN DUCT IS 

ATTACHED TO FURNACE TOP SIDE 

(HORIZONTAL LEFT OR RIGHT APPLI-

CATIONS) AS SHOWN.

Close coupled (less than 36") 

return (filter directly beneath bottom 

side return) not recommended due to 

noise considerations. If used, securely 

attach 1/2" mesh metal hardware cloth 

protective screen to the inside bottom of 

filter grill.

w

Close coupled (less than 36") return (filter directly beneath 

bottom side return) is not recommended due to noise 

considerations.

7. 

Connect  the  duct  work  to  the  furnace.  See  Outline 

Drawing  for  supply  and  return  duct  size  and  location. 

Flexible  duct  connectors  are  recommended  to  connect 

both supply and return air ducts to the furnace.
If only the front of the furnace is accessible, it is recommended 

that both supply and return air plenums are removable.

8.  When replacing a furnace, old duct work should be 

cleaned out. Thin cloths should be placed over the 

registers and the furnace fan should be run for 10 minutes. 

Don’t  forget  to  remove  the  cloths  before  you  start  the 

furnace.

RETURN AIR FILTER

These furnaces require high velocity type air filters which may 

be located within the furnace blower compartment for UPFLOW 

furnaces in either a BOTTOM or SIDE (left side or right side) 

return air inlet. See Figures 13 and 14. Some filters may need to 

be trimmed for side or bottom filter use.

NOTE:  On  upflow  5  ton  airflow  models,  if  the  airflow 

requirement exceeds 1800 CFM, these models will require 

return air openings and filters on both sides; OR 1 side and 

the bottom; OR just the bottom.

NOTE:    Upflow  models  only  -  Installation  of  the  alternate 

bottom filter kit requires the bottom flange to be bent flat.

Optional  downflow  furnace  filters  must  be  located  outside  the 

furnace cabinet. Typical installations are shown in Figures 14 and 

15. Tables 5 and 6 provide information for installation of the filter 

retaining brackets shipped with downflow furnaces.
