Apply a heavy bead of Mill Pac sealant(W573-0007) (not supplied) to the outer edge ofthe inner collar of the appliance. Attach the firstinner rigid pipe component and secure using aminimum of three #8 screws. Repeat using theouter rigid pipe. Seal using Red RTV Silicone (W573-0002) (not supplied).C. Insert the vent pipes through the fi restop maintaining the required clearance tocombustibles. Apply a heavy bead of Red RTV Silicone (W573-0002) (not supplied) to both theinner sleeve and outer sleeve of the air terminal. Slide the terminal sleeves into the rigid pipes a minimumof 1 1/4”. Holding the air terminal (lettering in an upright, readable position), secure to the exterior wall andmake weather tight by sealing with caulking (not supplied).The air terminal mounting plate may be recessed into the exterior wall or siding no greater than thedepth of the return flange.SCREWS#10x2"OUTERRIGIDPIPECAULKINGINNERRIGIDPIPE2” (50.8mm) OVERLAPHI-TEMPSEALANT5.4.5 horizontal air terminal installation5.5 using ridig vent componentsFOR REAR VENT ONLY: A 45° corner installation can have 0” (0mm)rise between the appliance combustion air collar and the air terminal.In this case, vent lengths must be kept to a maximum of 24” (61cm).For longer vent lengths, a minimum vertical rise of 24” (61cm) is required.A. Follow the instructions for "HORIZONTAL AIR TERMINALINSTALLATIONS" section.B. Continue adding components alternating inner rigid pipe and outerrigid pipe. Ensure that all inner rigid pipe and elbows have sufficientvent spacers attached and each component is sealed and securelyfastened to the one prior. Attach the inner telescopic sleeve to thevent run. Repeat using the outer telescopic sleeve. Seal and secureas before. To facilitate completion, attach inner and outer couplersto the air terminal.C. Install the air terminal.
