Step 7
Apply high temperature sealant to 4” (102 mm) and 7” (178 mm) collars or the termination one inch away from crimped end. Guide the vent terminations 4” and 7” collard into their respective vent pipes. Double check that the vent pipes overlap the collars by 2” (51 mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof. As an alternative to screwing the termination directly to the wall, you may also use expanding plugs or an approved exterior construction adhesive. You may also attach the termination with screws through the inner body into the 4” vent pipe, however for this method, you must extend the 4” pipe approximately 6” (152 mm) beyond the outer face of the wall.
Support horizontal pipes every 36” (914 mm) with metal pipe straps.

Flex Vent Pipe
NOTE: The 40” (1016 mm) flex vent is used for 90° off the top of the unit then out the back wall.
Follow Step 1 and 2 on Page 18.
Step 3
Install the four (4) spacer springs on the 4” flex vent pipe. When installing the spacer springs around the 4” pipe, stretch the spring to approximately 15” (381 mm), wrap the spring around the pipe and interlock the ends of the spacer spring approximately 2” (51 mm). Mea- sure 6³⁄₄” (172 mm) from the end of the pipe. Place the next spring 5” (127 mm) from the previously installed spring. Place the next spring 6” (152 mm) from the last spring. Finally place the last spring 12” (305 mm) from the last spring installed. (Fig. 36)

Step 4
Install the 4” (102 mm) flex vent pipe to the appliance collar as described on Page 13. Secure the end with the first spring 6³⁄₄” (172 mm) from the flex pipe end to the unit.
Step 5
Slide the 7” (178 mm) flex vent pipe over the 4” flex vent pipe and secure the 7” collar as described on Page 13.
Step 6
Bend the flex pipe horizontal so the bottom of the hori- zontal pipe measure 6¹⁄₂” (165 mm) from the top of the unit immediately after the 90° formation. (Fig. 37) Be sure to follow the 1/2” (13 mm) rise in a 12” (305 mm) horizontal run rule.
Step 7
Install the 4” flex then 7” flex to the termination.
