Clearance Requirements
The top, back, and sides of the fireplace are defined by
Minimum Clearances
from the Fireplace to Combustible Materials
Minimum Clearances
from the Vent Pipe to Combustible Materials
| Inches | mm |
Vertical Sections | 1 | 25 |
Horizontal Sections |
|
|
Top | 3 | 75 |
Bottom | 1 | 25 |
Sides | 1 | 25 |
At Wall Firestops |
|
|
Top | 2 1/2 | 63.7 |
Bottom | 1/2 | 13 |
Sides | 1 | 25 |
For minimum clearances, see the direct vent termination clearance diagrams on pages 19 and 20 in this manual.
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fireplace is set in place. Framing should be positioned to accommo- date wall coverings and fireplace facing material. The dia- gram below shows framing reference dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND VERIFY FRAMING METHODS AND WALL COVERING DETAILS BEFORE FRAMING.
Shows center of 12” x 12” vent framing hole for rear venting.
The center of the hole is one 
inch (25.4mm) above the center
of the horizontal vent pipe.

Top | 3 1/2 | 89 |
Ceiling* | 31 | 787 |
*The clearance to the ceiling is measured from the top of the unit, excluding the standoffs (see Figure 28).
The distance from the unit to combustible construction is to be measured from the unit outer wrap surface to the com-
