WARNING

fire, burns, explosions, electrical shock and carbon monoxide poisoning.

This fireplace is a vented product. This fireplace must be
properly installed by a qualified service person. The glass door
must be properly seated and sealed. If this unit is not properly
installed by a qualified 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 flu with head­aches, dizziness and/or nausea. If you have these signs, the
fireplace may not have been installed properly. Get fresh air
at once! Have the fireplace inspected and serviced by a quali­fied service person. Some people are more affected by carbon
monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those under the influence
of alcohol, and those at high altitudes.

Propane/LP gas and natural gas are both odorless. An odor­making agent is added to each of these gases. The 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.

IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

It is normal for fireplaces fabricated of steel to
give off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.

IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

It is not unusual for gas fireplace to give off some
odor the first time it is burned. This is due to the
manufacturing process.

Please ensure that your room is well ventilated

during burn off — open all windows.

It is recommended that you burn your fireplace for
at least ten (10) hours the first time you use it. Place
the fan switch in the “OFF” position during this time.

We suggest that our gas hearth
products be installed and
serviced by professionals who

Vent Configurations

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
termination.

You may use up to three 90° elbows in this vent configuration. See
Horizontal Termination Configurations on pages 20 and 21.

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. 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 flue gas exhaust.
Certain limitations apply to vent configurations 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 building. A chase is required
for such venting.

1

/4" rise for every 12" of run towards the

Never run the vent pipe level or
downward. This may cause excessive
temperatures which could cause
a fire.

WARNING

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.

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.

HOW TO USE THE VENT GRAPH

The Vent Graph should be read in conjunction with the following
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 intersecting 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 fireplace in

accordance with same.

Example A: If the vertical dimension from the floor of the

fireplace is 11' (3.4m) the horizontal run to the face of the
outer wall must not exceed 14' (4.3m).

Example B: If the vertical dimension from the floor of the

unit is 7' (2.14m), the horizontal run to the face of the
outer wall must not exceed 8

VENT INSTALLATION

HORIZONTAL (THROUGH THE WALL) TERMINATION CONFIGURATIONS

Since it is very important that the venting system maintain 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. See page 18.

Minimum clearance between vent pipes and combustible materials is 3" on top and 1" from bottom and sides unless
otherwise noted (Exception: Outside wall with firestop: 1" all around pipes are allowed).

When vent termination exits through foundations less than 20" below siding outcrop, the vent pipe must flush up with
the siding.

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 outer wall or the mounting flange of the termination.

When installing the appliance as a rear vent unit, the 90° 45° transition elbow
attached directly to the rear of the unit is NOT INCLUDED in the following criteria and
calculations, and unless specifically mentioned should be ignored when calculating
venting layouts.

WARNING

• The maximum number of 90° elbows per side wall installation is three (3). See Figure 21.

• If a 90° elbow is fitted directly on top of the fireplace flange, the maximum horizontal vent run before the termination
or a vertical rise is 20" (508mm). See Figure 22.

VENT INSTALLATION

HORIZONTAL (THROUGH THE WALL)
TERMINATION CONFIGURATION

• If a 90° elbow is used in the horizontal vent run (level height
maintained) the horizontal vent length is reduced by 36"
(914 mm) (Fig. 21 A and B) This does not apply if the 90°
elbows are used to increase or redirect a vertical rise. See

Figure 24.

Example: According to the vent graph (page 17) the
maximum horizontal vent length in a system with a 7.5'
vertical rise is 20’ (6m) and if a 90° elbow is required in
the horizontal vent it must be reduced to 17' (5.2 m).

In Figures 23 and 24, Dimension A plus B must not be greater
than 17' (5.2m).

• 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" (45cm). This
does not apply if the 45° elbows are installed on the vertical
part of the vent system.

• The maximum number of elbow degrees in a system is 270°.

VENT INSTALLATION

BELOW GRADE INSTALLATIONS

When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is recommended.
It allows installation depth down to 7" (178mm) below grade level. The 7" (178mm) is measured from the center of the
horizontal vent pipe as it penetrates through the wall.

Ensure that sidewall venting clearances are observed. If venting system is installed below ground, we recommend a
window well with adequate and proper drainage to be installed around the termination area.

If installing a snorkel, a minimum 24" vertical rise is necessary. The maximum horizontal run with the 24” vertical pipe is
36". This measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. See the
Sidewall Venting Graph for extended horizontal run if the vertical exceeds 24".

1. Establish vent hole through the wall.

2. Remove soil to a depth of approximately 16" below base of snorkel. Install drain pipe. Install window well (not supplied).
Refill hole with 12" of coarse gravel leaving a clearance of approximately 4" below snorkel. See Figure 26.

3. Install vent system.

4. Ensure a watertight seal is made around the vent pipe coming through the wall.

5. Apply high temperature sealant caulking (supplied) around the 4" and 7" snorkel collars.

6. Slide the snorkel into the vent pipes and secure to the wall.

7. Level the soil so as to maintain a 4" clearance below snorkel.

See Figure 17, page 19.

See Figure 26.

• Do not back fill around snorkel.

• A clearance of at least 4" must be
maintained between the snorkel and
the soil.

WARNING

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to
wall first, then secure to snorkel with self drilling #8x1/2 sheet metal screws. It will be necessary to extend vent pipes out as
far as the protruding wall face. See Figure 27.

INSTALLATION FOR VERTICAL TERMINATION

1. Determine the route your vertical venting will take. If ceiling joist,
roof rafters or other framing will obstruct the venting system,
consider an offset. See Figure 31 to avoid cutting load bearing
members.

Roof

Flashing

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 shows in Figure 14, page 18.

2. Set fireplace in desired location. Drop a line plumb down from
the ceiling to the position of the flue exit. Mark the center point
where the vent will penetrate the ceiling. Drill a small locating
hole a this point.

Drop a plumb line from the inside of the roof to the ceiling locat-

ing hole in the ceiling. Mark the center point where the vent will
penetrate the roof. Drill a small locating hole at this point.

FLAT CEILING INSTALLATION

1. Cut a 9

/2"x91/2" (241mm x 241mm) inside dimensions as shown in
Figure 32 using framing lumber the same size as the ceiling joist.
If the area above the ceiling is an insulated ceiling or a room, nail
firestop from the top side. This prevents loose insulation from fall­ing into the required clearance space. See Figure 32. Otherwise,
install firestop below the framed hole. The firestop should be
installed with no less than three nails per side. See Figure 33.

INSTALLATION FOR VERTICAL TERMINATION (CONTINUED)

4. Connect a section of pipe and extend up through the hole.

NOTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three (3) feet.
Use wall straps for this purpose. See Figure 31, page 26. Whenever possible, use 45° elbows instead of
90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.

5. Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and
framing with roofing nails. Be sure roofing material overlaps the top edge of the flashing. There must be a 1" clearance
from the vent pipe to combustible materials.

6. Continue to add pipe sections until the height of the vent cap meets the minimum requirements below.

NOTE: You must increase vent height for steep roof pitches. Nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors may cause poor draft or down-drafting in high winds. Increasing
the vent height may solve this problem.

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

FIREPLACE INSTALLATION

CHECK GAS TYPE

Use proper gas type for the fireplace you are installing. If you have conflicting gas type, do not install fireplace. See dealer
where you purchased the fireplace for proper fireplace according to your gas type.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

INSTALLATION ITEMS NEEDED

Before installing fireplace and burner system, make sure you
have the items listed below.

• External regulator (supplied by installer) • Tee joint

• Piping (check local codes) • Pipe wrench

• Sealant (resistant to propane/LP gas)

• Test gauge connection*

• Sediment trap (optional but recomended)

A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.

WARNING

For propane/LP units, never connect
fireplace directly to the propane/LP
supply. This burner system requires

• approved flexible gas line with gas connector (if allowed
by local codes — not provided)

* A CSA design-certified equipment shutoff valve with

NPT tap is an acceptable alternative to test gauge connec­tion. Purchase the CSA design-certified equipment shutoff
valve from your dealer.

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 35. Pointing the vent down protects it from freezing rain or sleet.

TROUBLESHOOTING

STANDING PILOT IGNITION

SYMPTOM POSSIBLE CAUSE ACTION

1. Spark ignitor
will not light
pilot after
repeated trig­gering of
piezo.

2. Pilot will not
stay lit after
carefully fol­lowing light­ing instruc­tions.

3. Pilot burning,
valve knob
turned to
“ON”, switch
is turned to
“ON” or “RS”,
but burner will
not ignite.

4. Frequent pilot
outage prob­lem.

A. Wire disconnected.

B. Defective ignitor.

C. No gas or low gas pressure.

D. No Propane/LPG in tank

A. Defective thermocouple

B. Defective valve

A. Defective switch, wall switch,

remote control or wire

B. Pilot flame too small

C. Defective or malfunctioning ther-

mopile

D. Defective valve

A. Pilot flame may be too high or too

low, causing pilot safety to drop
out

A. Open door and check to make sure wire is connected to ignitor.
B. Check for spark at electrode and pilot. If no spark and electrode

wire is properly connected, replace pilot assembly.

C. Check remote/manual shut off valve from fireplace. Low pressure

can be caused by bent lines, restricted lines, low pressure line
pressure. Consult with plumber or gas supplier.

D. Check Propane/LPG tank. Refill tank.

A. Check that thermocouple flame impinges on thermocouple. Clean

and/or adjust pilot for maximum flame impingement. Ensure that
the thermocouple connection at the gas valve is fully inserted and
tight.

Disconnect the thermocouple from the valve, place one millivolt

lead wire on the tip of the thermocouple and the other meter lead
wire on the thermocouple copper lead. Start the pilot and hold the
valve knob in. If the millivolt reading is less than 15 mV, replace
pilot assembly.

B. If thermocouple is producing more than 15 mV, replace faulty

valve.

A. Check switch and wire for proper connection. Place jumper wires

across terminals of switch. If burner comes on, replace defective
switch.If the switch is OK, repeat the same procedure on remote
control If burner comes on, replace remote control.

Place jumper wire across wire at gas valves (terminals marked TH

and TP/TH). If burner comes on, wires are faulty or connections
are bad. Replace wire.

B. If pilot flame is not close enough to the thermopile, adjust pilot

flame.

C. Check thermopile wire connections to make sure all are tight and

that the thermopile is fully inserted into pilot assembly. Check
thermopile with a millivolt meter. Connect leads to TP and TP/TH
terminals on the control valve. If meter reading is below 325 mV,
replace pilot assembly.

D. Turn valve knob to “On” and switch to “ON.” Take a reading at

the thermopile leads (TP & TP/TH) on the valve. If the meter
reads greater than 175 mV and the burner does not light, replace
defective valve.

A. Clean and adjust the pilot flame for maximum flame impingement

on thermocouple.

5. The pilot and
main burner
extinguish
while in oper­ation
