ENW415-1705 / A / 07.13.1727venting installation5.3 using either flexible or rigid vent componentsA. Stretch the inner flex pipe to the required length takinginto account the additional length needed for the finishedwall surface. Apply a heavy bead of the red RTV silicone(W573-0002) (not supplied) to the inner sleeve of the airterminal. Slip the vent pipe a minimum of 2” (50.8mm)over the inner sleeve of the air terminal and secure with aminimum of 3 screws.B. Using the outer fl ex pipe, slide over the outer combustionair sleeve of the air terminal and secure with a minimumof 3 screws. Seal using red RTV silicone (W573-0002)(not supplied).C. Insert the vent pipes through the firestop maintainingthe required clearance to combustibles. Holding the airterminal (lettering in an upright, readable position), secureto the exterior wall and make weather tight by sealingwith caulking (not supplied).D. If more vent pipe needs to be used to reach the fireplace,couple them together, as illustrated. The vent systemmust be supported approximately every 3 feet (0.9m) forboth vertical and horizontal runs. Use non-combustiblestrapping to maintain the minimum clearance tocombustibles.E. Stove Appliances Only: From inside the house, usingRed RTV Silicone (W573-0002) (not supplied), sealbetween the vent pipe and the firestop. Then slide the black trim collar over the vent pipe up to thefi restop.The air terminal mounting plate may be recessed into the exterior wall or siding no greater than thedepth of its return flange.18.1ADD FASTENER TYPEADD GRAPHIC17.1For safe and proper operation of the appliance, follow the venting instructionsexactly.The vent system must be supported approximately every 3 feet (0.9m) forboth vertical and horizontal runs. Use Wolf Steel Ltd. support ring assemblyor equivalent noncombustible strapping to maintain the minimum clearance tocombustibles for both vertical and horizontal runs.All inner flex pipe and outer flex pipe joints may be sealed using high temperaturered RTV silicone W573-0002 (not supplied) or the high temperature sealant W573-0007 Mill Pac (not supplied). However, the high temperature sealant W573-0007Mill Pac (not supplied) must be used on the joint connecting the inner flex pipe andthe exhaust flue collar.Use only approved fl exible vent pipe kits marked:“Wolf Steel Approved Venting” or “E2” as identified by the stamp only on the flex pipes.ElbowSpacers• Do not allow the inner flex pipe to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight.• Spacers are attached to the inner flex pipe at predetermined intervals to maintain an even air gap to the outerfl ex pipe. This gap is required for safe operation. A spacer is required at the start, middle, and end of eachelbow to ensure this gap is maintained. These spacers must not be removed.!
