45° Flex Vent Pipe
NOTE: Under no circumstances can ridged pipe or a rigid 45° elbow be used. The 7TCDV45KT must be used in a corner installation. The corner placement dimensions on Page 4 of the manual must be ad- hered to! Figures 16 & 18 show general installations. Refer to instructions below for a detailed description of installation.
1.Determine where the termination is to be in- stalled. Locate the center of the hole 29¹⁄₂” (749 mm) off the floor. (Fig. 16)
NOTE: The location of the termination hole must be adhered to!
2.Install the firestop as shown on Page 12.
3.Remove the flex vent and extend the flex vent out to its longest length.
4.Bend the tab on the back of the fireplace up. (Fig. 14)
5.Insert the collar on the flex vent that has the twist lock embosses on it onto the collar of the fire- place. Twist the collar to “lock it” onto the fire- place. Run a screw through the tab and into the collar to secure the collar onto the fireplace.
6.Bend the flex pipe up 90° as close to the fireplace as possible. (Fig. 17)
7.Slide the fireplace partially into the corner and, while holding the vertical portion of the flex vent pipe, grab the exposed end collar and bend it down to the height of the opening in the wall.
8.While pushing the unit in place, slide the collar through the firestop. NOTE: It may be necessary to trim some material off of the collar. The col- lar is made long to accommodate brick finished houses. (Fig. 19)
9.Secure the collar in place by running a screw through the tab in the firestop and through the collar.
10.Slide the termination into the collar and secure with the 4 screws provided. (Fig. 19)
