Step 1.

Determine the desired location of the appliance. Check to ensure that wall studs or roof rafters are not in the way when the venting system is attached. If this is the case, you may want to adjust the location of the appliance.

WARNING

Fire Hazard.

Exhaust Fume Risk.

Impaired Performance of Appliance.

•Ensure vent components are locked together correctly.

•Pipe may separate if not properly joined.

Step 2.

Direct vent pipe is designed with a locking connection. To connect the venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory. Wall thickness may vary. Remember to include wall thickness in minimum clearances when figuring venting lengths for your installation needs.

Note: Female ends of direct vent pipe/elbows are designed to slide straight onto the male ends of adjacent pipes by orienting the pipe indentations so they match and slide into the entry slots on the male ends, see Figure 5.4. Push the pipe sections completely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sections are fully locked. The female locking lugs may not be visible from the outside. They may be located by examining the inside of the female ends.
