WARNING: This gas fireplace and vent assembly
must be vented directly to the outside. The venting
system must NEVER be attached to a chimney serving
a separate solid fuel burning appliance. Each direct
vent gas appliance must use a separate vent system.
Do not use common vent systems.
WARNING: Vent pipe air space clearances to com-
bustibles are 1" on all sides except on the horizontal
sections, which require 2" clearances from the top
of the pipe. Where the termination cap penetrates a
combustible wall, 1" air space clearance is required.
INSTALLATION PLANNING
There are two basic types of direct vent installation:
• HorizontalTermination
• VerticalTermination
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations require only inner por-
tion of wall firestop. Horizontal installations using round termination
require exterior portion of wall firestop.
1. Set fireplace in its desired location and determine the route your
horizontal venting will take. Do not secure fireplace until all vent-
ing has been installed. Some installations require sliding fireplace
in and out of position to make final venting connections. Figures
15 and 16 on pages 12 and 13, show different configurations for
venting with horizontal termination that will help you decide which
application best suits your installation. Check to see if wall studs
or roof rafters are in the path of your desired venting route. If they
are, you may want to adjust location of fireplace.
2. Direct vent pipe sections and components are designed with
special twist-lock connections.
Twist-Lock Procedure: Female ends of pipes have locking lugs
(indentations). These lugs will slide straight into matching slots
on male ends of adjacent pipes. Push pipe sections together and
twist one section clockwise approximately one-quarter turn until
sections are fully locked (see Figure 9, page 11).
Note: Horizontal runs of vent must be supported every three feet.
Use wall straps for this purpose.
3. Assemble desired combination of pipe and elbows to fireplace flue
collar. If there are long portions of venting run, pre-assembled
pipe sections may be installed as subassemblies for convenience.
4. Carefully determine location where vent pipe assembly will pen-
etrate outside wall. Center of hole should line up with center line
of horizontal vent pipe. Mark wall for an 11 1/2" x 11 1/2" square
hole. Cut and frame square hole in exterior wall where vent will
be terminated. If wall being penetrated is constructed of noncom-
bustible material, such as masonry block or concrete, an 8 1/2"
hole with zero clearance is acceptable (see Figure 10).
WARNING: Do not recess vent termination into any
wall. This will cause a fire hazard.

VENTING INSTALLATION Continued
5. Noncombustible Exterior Wall: Position horizontal vent cap in center of
the 8 1/2" round hole and attach to exterior wall with four wood screws
provided. Before attaching vent cap to exterior wall, run a bead of non-
hardening mastic (pliable sealant) around outside edges to make a seal
between it and outside wall.
Note: Four wood screws provided should be replaced with appropriate
fasteners for stucco, brick, concrete or other types of sidings (see Figure
11).
Combustible Exterior Wall: For vinyl siding, stucco or wood exteriors,
a siding standoff may be installed between vent cap and exterior wall.
Siding standoff prevents excessive heat from damaging siding materi-
als. Siding material must be cut to accommodate standoff. Bolt vent
cap to standoff. Apply non-hardening mastic around outside edge of
standoff. Position standoff/cap assembly in the center of 11 1/2" square
hole and attach to exterior wall with provided wood screws (see Figure
12, page 12). Siding standoff must sit flush against exterior fascia
material.
6. Connecting Vent Cap with Horizontal Vent Pipe: Slide wall firestop over
vent pipe before connecting horizontal run to vent cap (see Figure 13,
page 12).
Carefully move fireplace, with vent assembly attached, toward wall and
insert vent pipe into horizontal termination. Pipe overlap should be a
minimum of 1 1/4" (see Figure 14, page 12).
Slide wall firestop against interior wall surface and attach with screws
provided. See Figure 14, for horizontal termination details.
Place fireplace into position and shim with noncombustible material if
needed. Nail or screw side flanges to framing to secure unit in place.
IMPORTANT: Make sure fireplace is level before securing. If fireplace is
not level it will not work properly.

Horizontal Termination Configurations
Figure 15 shows a configuration for venting with horizontal termi-
nation with a chart of critical minimum and maximum dimensions
which MUST be met.
Figure 16, page 13, shows a configuration for venting with horizontal
termination using two 90° elbows with a chart of critical minimum
and maximum dimensions which MUST be met.
If using a venting configuration of only horizontal venting with no
vertical run, a ¼'' rise for every 12'' of run toward the termination
is required.
NOTICE: Do not seal termination cap to vent pipe. Cap
must be removable for vent inspection and mainte-
nance.
WARNING: Never run vent downward as this may
cause excessive temperatures which could cause a
fire. Operation of improperly installed and maintained
venting system could result in serious injury, property
damage or loss of life.

Vertical Termination Installation
Note: Vertical restrictor must be installed in all vertical installations.
1. Determine route your vertical venting will take. If ceiling joists,
roof rafters or other framing will obstruct venting system, consider
an offset (see Figure 17) to avoid cutting load bearing members.
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 venting system and any maximum horizontal offset limitations.
2. Set fireplace in desired location. Drop a plumb line down from
ceiling to position of fireplace exit flue. Mark center point where
vent will penetrate ceiling. Drill a small locating hole at this point.
3. Drop a plumb line from inside of roof to locating hole in ceiling.
Mark center point where vent will penetrate roof. Drill a small
locating hole at this point.
45° Elbow
Wall Strap

Ceiling Firestop
Flat Ceiling Installation
1. Cut an 11 1/2" square hole in ceiling using locating hole as a center
point. Opening should be framed to 11 1/2" x 11 1/2" inside dimen-
sions, as shown in Figure 10 on page 11 using framing lumber
the same size as ceiling joists. If area above ceiling is an insulated
ceiling or an attic, nail firestop from top side. This prevents loose
insulation from falling into required clearance space. If area above
ceiling is a living space, install firestop below framed hole. Firestop
should be installed with no less than three nails per side (see Figure
15, page 12).
2. Assemble desired lengths of pipe and elbows necessary to reach
from fireplace flue up through firestop. Be sure all pipe and elbow
connections are fully twist-locked (see Figure 9, page 11).
3. Cut a hole in the roof using locating hole as a center point. (Cover
any exposed open vent pipes before cutting hole in roof.) The
11 1/2" x 11 1/2"holemustbemeasuredonthehorizontal;actual
length may be larger depending on pitch of roof. There must be
a 1" clearance from vent pipe to combustible materials. Frame
opening as shown in Figure 10, page 11.
4. Connect a section of pipe and extend up through hole.
Note: If an offset is needed to avoid obstructions, you must sup-
port vent pipe every 3 feet. Use wall straps for this purpose (see
Figure 17). Whenever possible, use 45° elbows instead of 90°
elbows. The 45° elbow offers less restriction to the flow of flue
gases.
5. Place flashing over pipe section(s) extending through roof. Secure
base of flashing to roof and framing with roofing nails. Be sure
roofing material overlaps top edge of flashing as shown in Figure
17. There must be a 1" clearance from vent pipe to combustible
materials.
6. Continue to add pipe sections until height of vent cap meets the
minimum building code requirements described in Figure 8 on
page 9.
Note: You must increase vent height for steep roof pitches. Nearby
trees, adjoining rooflines, steep pitched roofs and other similar
factors may cause poor draft or down-drafting in high winds.
Increasing vent height may solve this problem.
7. Twist-lock vent cap onto last section of vent pipe.

Note: If vent pipe passes through any occupied areas above first floor,
including storage spaces and closets, you must enclose pipe. You may
frame and sheetrock enclosure with standard construction material. Make
sure and meet the minimum allowable clearances to combustibles. Do not
fill any required air spaces with insulation.

FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the fireplace unit you are installing. If you
have conflicting gas types, do not install fireplace. See retailer where
you purchased the fireplace for proper fireplace according to your
gas type.
INSTALLING GAS PIPING TO FIREPLACE LOCATION
WARNING: A qualified service person must con-
nect fireplace to gas supply. Follow all local codes.
CAUTION: For propane/LP units, never connect
fireplace directly to the propane/LP supply. This fire-
place requires an external regulator (not supplied).
Install the external regulator between the fireplace
and propane/LP supply.
WARNING: For natural gas, never connect fireplace
to private (non-utility) gaswells. This gas is commonly
known as wellhead gas.
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
• externalregulator(suppliedbyinstaller)
• piping(checklocalcodes)
• sealant(resistanttopropane/LPgas)
• equipmentshutoffvalve*
• testgaugeconnection*

• pipewrench
• approvedexiblegaslinewithgasconnector(ifallowedbylocal
codes)
* An equipment shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the equipment shutoff
valve from your retailer.
For propane/LP connection 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 14" of
w.c. pressure. If you do not reduce incoming gas pressure, fireplace
regulator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 21. Pointing the vent down protects
it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in certain
areas. Check your local codes. Use pipe of 1/2" diam-
eter or greater to allow proper gas volume to fireplace.
If pipe is too small, undue loss of volume will occur.
Installation must include an equipment shutoff valve, union and
plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from fireplace (see Figure 22).
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 appliance.

We recommend that you install a sediment trap/drip leg in supply line
as shown in Figure 22, page 15. Locate sediment trap/drip leg where
it is within reach for cleaning. Install in piping system between fuel
supply and fireplace. Locate sediment trap/drip leg where trapped
matter is not likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into fireplace gas controls.
If sediment trap/drip leg is not installed or is installed wrong, fireplace
may not run properly.

INSTALLING BATTERIES IN WIRELESS HAND-HELD REMOTE
CONTROL AND RECEIVER
Installing Batteries in Remote Receiver
1. Open bottom access door.
2. Remove switch plate from receiver.
3. Gently pull receiver from mounting bracket. The receiver is still
connected to the valve.
4. Remove battery housing cover on remote receiver to expose bat-
tery housing (see Figure 35).
5. Install 4 AA batteries into housing following positive and negative
directions on battery housing cover removed in step 3 (see Figure
35).
6. Replace battery housing cover, place back into mounting bracket
and cover with switch plate.
7. Install 2 D batteries into AC backup battery pack.
8. Close bottom access door.
MATCHING SECURITY CODES
Each remote control can use one of 65,536 unique security codes.
It may be necessary to program the remote receiver to "LEARN" the
security code of the remote control upon initial use, if batteries are
replaced or if a replacement remote control is purchased from your
dealer. When matching security codes, be sure the slide button on
thereceiverisintheREMOTEposition;thecodewillnot"LEARN".
If the slide switch is in the ON or OFF position. Program the remote
receiver to "LEARN" a new security code by pushing the LEARN but-
ton on the top of the remote receiver and then pressing the MODE
button on the remote control. A change in the beeping pattern, at the
receiver, indicates the remote control's code has been programed into
the receiver. When an existing receiver is matched to a new remote
control, the new security code will override the old one.
The microprocessor that controls the security code matching pro-
cedure is controlled by a timing function. If you are unsuccessful in
matching the security code on the first attempt, wait 1-2 minutes
before trying again. This delay allows the microprocessor to reset its
timer circuitry and try up to two or three more times.

BATTERY LIFE
Life expectancy of the alkaline batteries in the remote control should
be at least 12 months. Check and replace all batteries annually. When
the remote control no longer operates the remote receiver from a
distance it did previously or the remote receiver does not function at
all, the batteries should be checked. It is important that the remote
receiver batteries are fully charged and provide continuous output
voltage of at least 5.3 Volts. The length of the wire, the more battery
power is required to deliver signals between the remote receiver and
the gas valve. Recommended length is no longer than 20 feet The
remote control should operate with as little as 9.0 Volts battery power.
TROUBLESHOOTING
If you encounter problems with your fireplace system, the problem
may be with the fireplace itself or it could be with the remote control.
Review the fireplace manufacturer's operation manual to make sure
all connections are properly made. Then check the operation of the
remote in the following manner:
• Make sure the batteries are correctly installed in the receiver. One
reversed battery will keep the receiver from operating properly.
• Check batter in remote control to make sure contacts are touching
(+) and (-) ends of battery. Bend metal contacts in for tighter fit.
• Be sure receiver and remote control are within 20 to 25 feet
operating range.
• Keep receiver from temperatures exceeding 130°F. Battery life
is shortened about this level.
• If receiver is installed in tightly enclosed metal surround, the
operating distance will shorten.
ADJUSTMENTS
• To adjust at the receiver, use a small slotted screwdriver. Turn
the adjustment screw counter-clockwise about 5 degrees or a
maximum of 1/8 turn. This should correct the distance problem.
• If the problem is not corrected, return adjustment screw to
original position and then turn adjustment screw clockwise.
• This adjustment is like turning your radio dial. If you keep turning
the adjustment screw, in either direction, you will go past the
proper setting (tuning).
