Combustion Air Assy. Model OAC4
Installation of the Model 403 Duct Connector

1.  Push  the  insulation  back  approximately  2”  from  the 

end of  each duct.

2.  Slip each duct over the duct connector until an equal 

length of the connector extends into each duct.

3.  Place  a  duct  clamp  over  the  end  of  each  duct  and 

tighten it down snugly.

4.  Push the insulation back into place and over the duct 

clamp.

Model OAC4 Combustion Air Assembly

1.  Remove the cover cap from the 4” outlet opening loca-

tion on the left or right outside surface of the fireplace. 
DO  NOT  REMOVE  THE  COVER  IF  THE  OUTSIDE 
AIR WILL NOT BE CONNECTED.

2.  Fasten the 4” starting collar over the hole on the left or 

right side of the fireplace with the four (4) sheet metal 
screws provided. 

Figure 24

3.  Cut a 6” diameter opening for model OAC4 in the out-

side  wall  covering  where  the  model  OAC4  outside 
grille is to be located. 

Figure 26

FP1904

4.  Select  and  cut  a  piece  of  duct  of  sufficient  length  to 

attach to the fireplace and protrude at least 3” beyond 
the  face  of  the  wall  to  which  the  OAC4  inlet  air  box 
assembly will be attached. The duct may be cut with a 
standard pocket knife. Use FP-4-U duct for maximum 
efficiency and safety. Do not use a combustible duct. 
Always use UL listed Class 0 or 1 duct material.

5.  If  the  duct  is  the  insulated  type,  push  the  insulation 

back from one end of the duct approximately 2”. 

Figure 

27

6.  Slip the exposed end of the duct over the flange tube 

of the fireplace.

7.  Place the duct clamp around the exposed end of the 

aluminum duct.

8.  Slip the band through the housing, then pull the band 

tight around the duct.

9.  Snap the band locking screw down and tighten it with 

a screwdriver or nutdriver. 

Figure 27

10.Nail or screw the combustion air assembly to the sur-

face of the wall.

NOTE:

 If the wall covering is brick or stone, use appro-

priate masonry fasteners. Mount the combustion air as-
sembly  with  “TOP”  up  to  prevent  rain  from  entering  the 
assembly. Be sure the 6” diameter opening around the air 
duct is sealed with insulating material to prevent cold air 
from entering through the wall. If it is necessary to splice 
the duct, a model 403 duct connector should be installed 
as described in 

Figure 26
