The vent chart should be read in conjunction with the 
following vent installation instructions to determine the 
relationship of the vertical and horizontal dimensions of 
the vent system.
1.  Determine the height of the center of the horizontal 

vent pipe exiting through the outer wall. Using this 
dimension on the Sidewall Vent Graph bellow, locate 
the point intersecting with slanted graph line. 

2.  From the point of this intersection, draw a vertical 

line to the bottom of the graph.

3.  Select the indicated dimension, and position the 

fireplace in accordance with same. 

Example A:
  If vertical dimension from floor of the fireplace is 11’ 

(3.4 m), horizontal run to the face of outer wall must 
not exceed 14’ (4.3 m).

Example B:
  If vertical dimension from floor of the unit is  

7’ (2.14 m), horizontal run to the face of outer wall 
must not exceed 8¹⁄₂’ (2.6 m).

When installed as a rear vent unit this appliance may be 
vented directly to a termination located on the rear wall 
behind the appliance.

• 

Specific rear vent starter kits must be used in these 
applica

tions (see ‘venting components’). The appli-

ance has been approved for installation flat against a 
rear wall. (Fig. 17)

• 

Maximum horizontal distance between the rear of 
the appliance and the outside face of the rear wall is 
20” (508 mm). (Fig. 17)

• 

Minimum clearances between any combustible ma-
terial and the vent pipe sections are:

 

Top  ..............................................2” (51 mm)

 

Sides  ...........................................1” (25 mm)

 

Bottom  .........................................1” (25 mm)

Max. 20”

(508mm)

Step 1
Locate and cut vent opening in the rear wall.
Combustible walls:  Cut a rectangular hole measuring 
10³⁄₈” H x 9³⁄₈” W (265 x 240 mm) through the exterior 
wall and frame. Frame in the opening per Figure 18.
Noncombustible walls:  Cut a round hole measuring 
7¹⁄₂” (190 mm) diameter through the exterior wall and 
frame. (Fig. 18) 
STEP 2
For combustible walls:  Measure wall thickness and cut 
zero clearance sleeve parts to proper length.  
Max. length is 12” (305 mm). Assemble sleeve  
to its maximum opening of 10³⁄₈” x 9³⁄₈” (265 x  
240 mm), and attach to firestop with #8 sheetmetal 
screws (supplied). Install firestop assembly. (Fig. 19) 
NOTE: Zero clearance sleeve is required only for com-
bustible walls.
