ing (air inlet tube) a barrier should be installed above the wall opening 

(air inlet tube) to prevent insulation from coming in contact with the air 

inlet tube.  The barrier must not penetrate into the 7 1/2" diameter wall 

opening.  Place the flat surface of the wall mounting bracket toward the 

wall.  Insert half round flange of wall mounting bracket into and at the 

top of the wall opening.  Level the wall mounting bracket in the wall 

opening.

On solid wall, when using wall studs for attachment of wall mounting 

bracket, fasten wall mounting bracket to wall studs with two (2) 10 x 1 

1/2" screws and fasten two (2) additional 10 x 1 1/2" screws through the 

wall mounting bracket and into the solid wall.

On sheet rock wall, when using wall studs for attachment of wall 

mounting bracket, fasten wall mounting bracket to wall studs with four 

(4) 10 x 1 1/2" screws or four (4) plastic expansion anchors.

1.  After  locating  mounting  holes,  drill  four  (4)  5/16"  diameter  holes 

into the wall.

2.  Insert four (4) plastic expansion anchors provided into the holes.

3.  Tighten four (4) #10 x 1" screws provided into the plastic expansion

10 x 1/2" screws.

5.  When facing the furnace, the two (2) clearance holes for attaching

casing top and above the combustion chamber.

6.  Insert  tubes  through  wall  opening  as  you  hang  the  furnace  on 

the  wall  mounting  bracket  by  aligning  two  *2)  tabs  on  the  wall 

mounting  bracket  with  two  (2)  slots  located  on  inner  casing  top.
