NSTALLATION

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 8.

Notes:

(1) Twist-lock procedure: four indentations, located on the female end of the pipes and fittings, are designed to

slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe indentations so they

match and slide into the four entry slots on the male end.
(2) Horizontal runs of vent pipe must be supported every three feet. 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.
STEP 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 9). The center of the square hole should match the centerline 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. Refer to Figure 8. 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.
