QUALIFIED INSTALLERS ONLY

HORIZONTAL INSTALLATION:

STEP 1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is attached. If this is the case, you may want to adjust the location of the appliance.

STEP 2. Direct vent pipe and fittings are designed with special twist-lock connections. Assemble the desired combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall or floor, as much out of view as possible.

Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe (non-flared end). Place a bead of high temperature silicone on the male edge of the outer pipe. Push the pipe sections completely together, then twist-lock one section clockwise approximately 1⁄4 turn, until the two sections are fully locked. The female locking lugs will not be visible from the outside, on black

pipe. They may be located by examining the inside of the
female ends as shown in Figure 16.					10"
