78D2082
WDV See-thru Gas Fireplace
installation planning
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
WARNING
Vent installation
Never run the vent pipe level down. This may
cause excessive temperatures which could
cause a fire.
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 7Z\x feet of vertical rise from the floor of the fireplace. With 7Z\x feet or more vertical rise from the floor of the fireplace, the horizontal run may
run level. NEVER run vent piping down.
You may use up to three 90° elbows in this vent configuration. Refer to Vertical/Horizontal Termination Configurations on Page 15.
For vertical termination
Measure the distance from the fireplace floor to the ceiling. Add the ceiling thickness, the vertical
rise in an attic or second story, and allow for sufficient 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, firestops are required at each floor 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.
Refer to Installing A Vent System in an Outside 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 flue gas exhaust. Certain limitations apply to vent configurations and must be
strictly followed.
Installing a vent system in an outside chase
NOTICE
When installing in a chase, you should insulate the chase as you would the
outside walls of your home. This is especially important in cold climates.
Insulation should be considered a combustible material. Maintain proper
clearances to all combustible materials.
NOTICE
Treatment of firestops and construction of the chase may vary from
building type to building type. These instructions are not substitutes for
the requirements of local building codes. You must follow all local building
codes.
WARNING
A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a
building. A chase is required for such venting.
Always maintain minimum clearances around vent systems. The minimum
clearances to combustibles for horizontal and vertical vent pipe are 1" at the
top, sides and bottom of the vent system. Do not pack the open air spaces with
insulation or other materials. This could cause high temperatures and may present
a fire hazard.

Step 1
Locate vent opening on the wall. It may be necessary to
first position the fireplace and measure to obtain hole location. Depending on whether the wall is combustible or
noncombustible, cut opening to size. Figure 11 (For combustible walls first frame in opening.)
Combustible Walls: Cut a 10Z\x”H x 10Z\x”W (267 x 267

Guide the vent terminations 5” and 8” collard into their
respective vent pipes. Double check that the vent pipes
overlap the collars by a minimum 1Z\v” (32 mm). Secure
the termination to the wall with screws provided and caulk
around the wall plate to weatherproof. As an alternative to
screwing the termination directly to the wall, you may also
use expanding plugs or an approved exterior construction
adhesive.

Since it is very important that the venting system main(508mm)
tain its balance between the combustion air intake and
the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 10
NOTE: Horizontal and vertical sections of this vent system
require a minimum of 1" clearance to combustibles at the
top, sides and bottom.
When vent exits through foundations less than 20" below
outcrop, the termination must be flush up with outcropped
wall above.
It is best to locate the fireplace 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 flue collar of the fireplace (or the top of the
Transition Elbow) to the face of the finished outside wall.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 14
• A minimum of 12" is required before a 90° elbow. If a 90°
elbow is fitted directly after 12" vertical section mounted
to the top of the fireplace, the maximum horizontal vent
run before the termination or a vertical rise is 36” (914
mm). Figure 15
FP1381
Figure 15 Maximum Horizontal Run with No Rise
In Figures 16 and 17 dimension A plus B must not be
greater than 17' (5.2 m).
• The maximum number of 45° elbows permitted per side
wall installation is two (2). These elbows can be installed
in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18" (45
cm). This does not apply if the 45° elbows are installed
on the vertical part of the vent system.

NOTE: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in Figures 22 and 23.

• External regulator (supplied by installer) • Piping (check local codes)
• Equipment shutoff valve*
• Sealant (resistant to propane/LP gas)
• Test gauge connection*
• Sediment trap (recommended)
• Tee joint
• Pipe wrench
• Approved flexible gas line with gas connector (if allowed by local codes — not provided)

CAUTION
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not
reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 32. Pointing the vent down protects it from freezing rain or sleet.
Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be used per National Fuel Code, Section
2.6.3, providing gas meets hydrogen sulfide
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data
plate) at the maximum flow rate (BTU/hr).
Undue pressure loss will occur if the pipe
is too small.
When using copper of flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide
a 1/8" test point up stream of the control.
Always provide a union when using black iron pipe so
the gas line can be easily disconnected for burner or fan
servicing. Refer to gas specifications for pressure details
and ratings.
The fireplace valve must not be subjected to any test pressures exceeding 1/2 psi. Isolate or disconnect this and
any other gas appliance control from the gas line when
pressure testing.

1/8" NPT pressure tapping point should be installed upstream of the appliance. Figure 33
Check your building codes for any special requirements for
locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe
could result in clogged burner system valves.
CAUTION
IMPORTANT: Install main gas valve (equipment shutoff valve) in an accessible location. The main gas
valve is for turning on or shutting off the gas to the fireplace.
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
We recommend that you install a sediment trap/drip leg in
supply line as shown in Figure 33. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system. Locate sediment trap/drip leg
where trapped matter is not likely to freeze. A sediment trap collects moisture and contaminants and
keeps them from going into the burner system gas controls. If sediment trap/drip leg is not installed
or is installed wrong, burner system may not run properly.
