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 ¼ 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 25.

Notes:
(a) Twist-lock procedure: four (4) indentations, located on the female								10"
end of the pipes and fittings, are designed to slide straight onto the								(254mm)
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								10"
male end.
								(254mm)
(b) Horizontal runs of vent pipe must be supported every 36” (915mm).
Wall straps are available for this purpose, also when running horizontal
pipe	minimum	clearances	to	combustibles	must	be	maintained;
2” (51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at
bottom.
3. With the pipe attached to the stove in the correct location, mark the
wall for a 10” (25.4cm) x 10” (25.4 cm) square hole (refer to Figure
26). The center of the square hole should match the center line of								Figure 26: Wall Framing Hole for
the horizontal pipe. Cut and frame the 10” (25.4cm) x 10” (25.4cm)
hole in the exterior wall where the vent will be terminated. Refer to								Horizontal Installation.
Figure 18. If the wall being				11/4"
penetrated is constructed of
non-combustible material i.e.				(3.2cm)
masonry or concrete, a 7”				Fold strap				Woodscrews
(17.8cm) hole is acceptable.				here

4. Position the horizontal vent
termination				in	the		center		Sheet metal
of	the	10”		(25.4cm)			x	10”	screws
(25.4cm)			hole,		and		attach
to	the		exterior			wall		with
the	four		screws			provided.			Wall Thimble
