unit is not properly installed by a qualied service person
with glass door properly seated and sealed, combustion
leakage can occur.
CARBON MONOXIDE POISONING: Early signs of
carbon monoxide poisoning are similar to the u with
headaches, dizziness and/or nausea. If you have these
signs, the replace may not have been installed properly.
Get fresh air at once! Have the replace inspected and
serviced by a qualied service person. Some people

odor helps you detect a gas leak. However, the odor
added to these gases can fade. Gas may be present
even though no odor exists.

VENT INSTALLATION
INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent pipe for the type of termination you choose. It is
also important to note the wall thickness.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise desired. All horizontal run
of venting must have 1/4" rise for every 12" of run towards
the termination below 71/2 ft. of vertical rise. With 71/2 ft. or
more vertical rise, the horizontal run may runlevel. NEVER
run vent piping downward.
You may use up to three 90° elbows in this vent congu-
ration. Refer to Horizontal Termination Congurations on
pages 20 and 21.
FOR VERTICAL TERMINATION
Measure the distance from the replace oor to the ceiling. Add the ceiling thickness, the vertical
rise in an attic or second story, and allow for sufcient vent height above the roof line.
NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios
when using 45° elbows. The appliance is approved for use with three 90° elbows maximum
or a combination of 90° and 45° elbows up to a maximum of 270°.
For two-story applications, restops are required at each oor level. If an offset is needed in the attic,
additional pipe and elbows will be required.
You may use a chase with a vent termination with exposed pipe on the exterior of the house. See
Installing Vent System in a Chase below. If pipe is enclosed in chase, it is not exposed.
It is very important that the venting system maintain its balance between the combustion air intake and
the ue gas exhaust. Certain limitations apply to vent congurations and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN OUTSIDE CHASE
A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a build-
ing. A chase is required for such venting.

AND NONCOMBUSTIBLE EXTERIORS
Figure 12 - Allowable Venting Chart
HOW TO USE THE VENT GRAPH
The Vent Graph should be read in conjunction with the follow-
ing vent installation instructions to determine the relationship
between the vertical and horizontal dimensions of the vent
system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph below, locate the point inter-
secting with the slanted graph line.
2. From the point of this intersection, draw a vertical line to
the bottom of the graph.
3. Select the indicated dimension, and position the replace
in accordance with same.
Example: If the vertical dimension from the oor of the
replace is 11' (3.4m) the horizontal run to the face of the
outer wall must not exceed 14' (4.3m).
Example: If the vertical dimension from the oor of the unit
is 7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 81/2' (2.6m).

When installed as a rear vent unit this appliance may be vented directly to a termination
located on the rear wall behind the appliance
• The maximum horizontal distance between the rear of the appliance and the outside of
termination is 20" (508 m). Figure 14
• Only one 45° elbow is allowed in these installations.
VENTING INSTALLATION
Sealant is not required to assemble BDV/DVB
replace venting. Do not use silicone sealant
at the ue exhaust connections.
1. Find the pipe section’s direction label. The
label arrow shall be pointed away from
the rebox and toward the termination.
Firmly insert the initial rigid section/elbow
into the rebox outer collar. Simpson “GS”
and Selkirk “DT” outer walls are hemmed
and will snap into the collar’s tabs. Attach
Simpson’s DirectVent Pro by fully insert-
ing into the collar and securing with self
tapping screws. The screws shall only
penetrate the ue outer wall.
Refer to vent manufacturer’s installation
instructions to properly assemble ue.
2. Locate and cut the vent opening in the wall.
For combustible walls rst frame in
opening.

strictly adhered to.
The Vent Graph, showing the relationship between vertical and hori-
zontal side wall venting, will help to determine the various dimensions
allowable. Figure 20
NOTE: Horizontal sections of this vent system require a minimum of 3"
clearances to combustibles at the top of the ue unless the vertical run is
71/2feet or higher (top vent units only), the clearances for the horizontal
run is 1" at the top, and 1" clearance at the sides and bottom until the
ue penetrates the outside wall. A minimum 1" clearance all around the ue
is acceptable at this point of penetration.
Vertical sections of this vent system require a minimum of 1" clearance to
combustibles on all sides of the pipe.
When vent exits through foundations less than 20" below outcrop, the
termination must be ush up with outcropped wall above.
It is best to locate the replace in such a way that minimizes the number
of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the ue collar of the replace (or the top of the
