USING FLEXIBLE VENT COMPONENTS

USE ONLY WOLF STEEL LTD. 3” / 5” FLEXIBLE VENT COMPONENTS.

ELBOW

SPACERS

!WARNING

Do not allow the 3" flexible vent pipe to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1” air gap between the 3" and 5" flexible vent pipes all around is required for safe operation. A spacer is required at the start, middle and end of each elbow to ensure this gap is maintained. Spacers are attached to the 3" flexible vent pipe at predetermined intervals to maintain a 1” air gap to the 5" flexible vent pipe. These

spacers must not be removed.

For safe and proper operation of the fireplace, follow the venting instructions exactly.

All 3" flexible vent pipe and 5" flexible vent pipe joints may be sealed using high temperature sealant W573-0002 (not supplied) or the high temperature sealant W573-0007 Mill Pac (not supplied). However, the high temperature sealant W573-0007 Mill Pac (not supplied) must be used on the joint connecting the 3" flexible vent pipe and the exhaust flue collar.

Use only approved flexible vent pipe kits marked:

“Wolf Steel Approved Venting” as identified by the stamp only on the 5” flexible vent pipe.

Four inches (4”) is the minimum bend radius allowed for the 5” flexible vent pipe.

HORIZONTAL AIR TERMINAL INSTALLATION

1.Stretch the 3” flexible vent pipe to the required length taking into account the additional length needed for the finished wall surface. Apply a heavy bead of the high temperature sealant W573-0007 (not supplied). Slip the flexible vent pipe a minimum of 2” over the inner sleeve of the air terminal and secure with 3 - #8 screws.

NOTE: If using pipe clamps to connect vent components, 3 screws must also be used to ensure the connection cannot slip off.

2. Using the 5” flexible vent pipe, slide over the outer combustion
air sleeve of the air terminal and secure with 3 - #8 screws. Seal	FIGURE 10
using high temperature sealant W573-0002 (not supplied).
3. Insert the flexible vent pipe through the firestop maintaining the
required clearance to combustibles. Secure the terminal to the
exterior wall (lettering in an upright, readable position) and make
weather tight by sealing with caulking (not supplied).
4. If additional flexible vent pipe is required, couple them together
as illustrated. The vent system must be supported approximately	FIGURE 11
every 3 feet for both vertical and horizontal runs. Use non-
combustible strapping to maintain the minimum 1” clearance to
combustibles from the flexible vent pipe.

VERTICAL AIR TERMINAL INSTALLATION

1. Fasten the roof support to the roof using the screws provided. The roof support is optional. In this case the venting is to be adequately supported using either an alternate method suitable to the authority having jurisdiction or the optional roof support. Figure 12.

2.Stretch the 3" flex vent pipe to the required length. Slip the 3" flex vent pipe a minimum of 2” over the inner pipe of the air terminal connector and secure with 3 #8 screws. Seal using a heavy bead of high temperature sealant W573-0007 (not supplied). Figure 13.
