W415-1802 / A / 11.06.18EN12installation planningWhile the liners must be continuous from the appliance to the chimney cap, to achieve the needed length, they maybe coupled, using an approved coupler.We recommend that exhaust vents that pass through unheatedspaces, such as tall exterior chimneys, be wrapped in a protectivesleeve to minimize condensation and reverse flow symptoms. See"troubleshooting" section for details.This appliance is approved for use with a 3" (76mm) exhaust and airintake.A. OUTSIDE: Slip the one end of a liner a minimum of 2"(51mm) over the sleeve of the air terminal. Secure using3 screws. Then seal the joint and screw heads with hightemperature sealant. Repeat with the other liner.B. Gently stretch the liners to therequired lengths and insert into thechimney. Trim and fit the flashingplate to suit the chimney termination.Place the air terminal onto the top ofthe chimney. Make weather tight bysealing with caulking (not supplied).Fasten to the chimney with screwsand plugs (not supplied).C. INSIDE: Remove the securing screwfrom the front of the vent mountingassembly. Slide the vent mountassembly from the track. Route theflex liners through the slider. Attachand secure the liners to the ventmounting plate, ensuring that themarked exhaust liner is attached tothe exhaust collar.D. The appliance may now be pushed into the opening and the mounting plate assembly slid back intothe track, and the securing screw started. Once the appliance is in its final position, tighten the securingscrew until the slider makes contact with the front stop.2.2 chimney connectionChimney installation must conform to both national and local code requirements. The chimney must be lined withone 3" (76mm) diameter liner for intake and one 3" (76mm) diameter liner for exhaust. The minimum and maximumvent lengths are 10 (3m) and 35 (11m) feet respectively.
