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. Remember to include wall thickness in minimum clearances when figuring the measurements for your installation needs.

Note: Direct vent pipe is designed to slide straight onto the male ends of adjacent pipes and fittings 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, on the pipe or fittings. They may be located by examining the inside of the female ends.

WARNING

Fire Risk. Explosion Risk. Combustion Fume Risk.

Use vent run supports per installation instructions. Connect vent sections per installation instructions.

•Maintain all clearances to combustibles.

•Do NOT allow vent to sag below connection point to appliance.

•Maintain speciﬁed slope (if required).

Improper support may allow vent to sag or separate.

Step 3.

For installations using a support box/wall thimble (check pipe manufacturer's instructions), mark the wall for a 10 in. x 10 in. (254mm x 254mm) square hole. The center of the square hole should line up with the center line of the horizontal pipe, as shown in Figure 5.5, on the next page. Cut and frame the hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, i.e. masonry block or concrete, a 7 in. (178mm) diameter hole is acceptable.
