Initial Installation

QUALIFIED INSTALLERS ONLY

HORIZONTAL TERMINATION:

NOTES:
1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel
(away from the stove), there should be at least 1⁄4 inch (6.4 mm) of vertical travel. Never
allow the vent to run downward, as this could cause high temperatures or even present
the possibility of a fire.
2. The exterior of the horizontal
vent termination must not be
blocked or obstructed.
3. If the vent termination is not
being		attached to				wood,		the	Wall thimble
four	wood			screws		provided
									fire stop	Horizontal wall
should		be		replaced			with			termination
material appropriate fasteners.
4. For buildings with vinyl siding,										Wall framing
a vinyl standoff should be
installed between the vent cap									Elbow
and the exterior wall. Attach
the	vinyl		siding		standoff			to
the	horizontal				termination.
Note		that		the	termination				Exhaust
bolts onto the flat portion of									flex pipe
the standoff, providing an								air	Combustion air
space between the wall and									outer pipe
the vent termination. The air
gap	prevents excessive						heat
from possibly melting the vinyl
siding.
5. Horizontal				pipes		must		be	Figure 27. Horizontal Vent Termination
supported			every		3	feet	(914

mm). Plumber’s all round strap will suffice.

6.When running horizontal pipe, clearances to combustibles must be maintained 11⁄2 inches (38 mm) sides, 11⁄2 inches (38 mm) bottom, and 2 inches (51 mm) top.

Step 1. Set the fireplace in the desired location. Check to determine if wall studs will be in the way when the venting system is attached. If this is the case, the location of the fireplace may have to be adjusted or the venting may have to be offset.

Step 2. Direct vent pipe sections are designed with special twist-lock connections. Dry fit the desired combination of pipe and elbows to the appliance adaptor.

Step 3. With the pipe in the correct position and attached to the fireplace, mark the wall for a 10 inches (25.4 cm) x 10 inches (25.4 cm) square hole (see Figure 24). The center of the hole should match the center line of the horizontal pipe. Cut and frame the hole in the exterior wall where the vent will be terminated. If the wall being penetrated is made of a non-combustible material (i.e. masonry or concrete) a 7 inches (17.8 cm) hole is acceptable.
