Pipe Clearances to Combustibles Fire Risk. Explosion Risk. Maintain vent clearance to combustibles as specified. • Do not pack air space with insulation or other materials. Failure to keep insulation or other materials away from vent pipe may cause fire. WARNING HEAT SHIELD 3 IN MIN. (76 mm) COMBUSTIBLE SURFACE Figure 6.2 Figure 6.1 Pipe Clearances 1 in. CLEARANCE AROUND VERTICAL SECTIONS 3 in. TOP CLEARANCE 1 in. SIDE AND BOTTOM CLEARANCE COMBUSTIBLE SURFACE DIRECTION UP HEAT SHIELD 90. ELBOW CORRECT INCORRECT Fasten the shield in place using the four pilot holes provided in the part. • Position the shield so the longest dimension (13 1/2 inch) is placed in same direction the elbow is pointing. • Center the shield directly above the elbow with a 1/2 inch air space between shield and combustible surface (see Figure 6.3). Figure 6.3 WARNING Fire Risk. Installation of this appliance may require the use of heat shield 385-920 above the first 90. elbow in the venting system. • Heat shield required if vertical distance between top of horizontal elbow and any combustible surface above elbow is less than 4 inches. • Heat shield not required if distance is more than 4 inches. • Attach elbow heat shield to the exhaust pipe if combustible materials are not present at install (see Figure 6.4). • Cut the tabs as shown and bend down. Using the screws found in the manual bag secure the heat shield to the pipe maintaining 3 to 4 inches between the pipe and shield. SCREW 3 in.

Wall Penetration Framing Combustible Wall Penetration Frame a hole in a combustible wall for an interior wall shield fi restop, (Figure 6.3) whenever a wall is penetrated. Use same size framing materials as those used in the wall construction. The wall shield fi restop maintains minimum clearances and prevents cold air infi ltration. Non-Combustible Wall Penetration If the hole being penetrated is surrounded by noncombustible materials such as concrete, a hole with diameter one inch greater than the pipe is acceptable. Whenever a non-combustible wall is penetrated, the wall shield fi restop is only required on one side and no heat shield is necessary. If your local inspector requires the wall shield fi restop on both sides, then both wall shield fi restops must have a heat shield attached to them. Figure 6.5 Horizontal venting clearances to combustible materials NOTE: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm). The heat shield is designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184 mm) thick. If wall thickness is less than 4 in. (102 mm) the existing heat shields must be fi eld trimmed. If wall thickness is greater than 7-1/4 in. (184 mm) a DVP-HSM-B will be required. Figure 6.6 Exterior Wall Hole * Shows center of 10” x 12” vent framing hole for top venting. The center of the hole is (1) inch (25.4 mm) above the center of the horizontal vent pipe. With minimum vertical or 12 inch and 90. elbow. HEAT SHIELD 3 IN.

Vertical Penetration Framing WARNING Fire Hazard Keep loose materials or blown insulation from touching the vent pipe. • National building codes recommend using attic shield to keep loose materials/ blown insulation from contacting vent. • Hearth & Home Technologies requires the use of an attic shield. Installing the Ceiling Firestop • Frame an opening 10 inches by 10 inches whenever the vent system penetrates a ceiling/floor (see Figure 6.4). • Frame the area with the same sized lumber as used in ceiling/fl oor joist. • When installing a top vent vertical termination appliance the hole should be directly above the appliance, unless the flue is offset. • Do not pack insulation around the vent. Insulation must be kept away from the pipe. Installing Attic Shield Note: An additional ceiling firestop is not required if attic shield is used. • Frame opening for attic shield. • Attic shield may be installed above or below ceiling (see Figure 6.5). • Secure with three fasteners on each side. • Fold tabs at top of attic shield in toward vent pipe. Tabs must keep vent pipe centered within shield. • Field construct additional shield height if insulation is deeper than height of attic shield. Figure 6.4 ATTIC ABOVE 10 IN.
