Initial Installation

QUALIFIED INSTALLERS ONLY

HORIZONTAL INSTALLATION:

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.

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 23.

Notes:
•	Twist-lock procedure: four (4)
	indentations, located on the female
Female	end of the pipes and fittings, are
Locking	designed to slide straight onto the
Lugs
Sealant	male ends of adjacent pipes and
	fittings, by orienting the four pipe
Male	indentations so they match and slide
Locking	into the four entry slots on the male
Lugs
	end.

• Horizontal runs of vent pipe must be supported every three ft. Wall straps are available for this purpose, also

when running horizontal pipe minimum clearances to combustibles must be maintained; 2 inches (5.1 cm) at top, 11⁄2 inches (3.8 cm) at sides, 11⁄2 inches (3.8 cm) at bottom.

3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4 cm) x 10” (25.4 cm) square hole (refer to Figure 25). The center of the square hole should match the center line of the

horizontal pipe. Cut and frame the 10” (25.4 cm) x 10”

(25.4 cm) hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of non-combustible material i.e. masonry or concrete, a 7 inches (17.8 cm) hole is acceptable.
