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 fi replaces to give off some
odor the fi rst 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 fi replace for
at least ten (10) hours the fi rst time you use it. Place
the fan switch in the “OFF” position during this time.

INSTALLATION PLANNING

VENT INSTALLATION

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.

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

WARNING

1

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

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.

Treatment of fi restops 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: If the vertical dimension from the fl oor of the

fi replace is 1 1' (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 fl oor of the unit

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

VENT INSTALLATION

HORIZONTAL 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 Figure 13, page 17.

NOTE: Horizontal sections of this vent system require a minimum of 3" clearances to combustibles at the top of the
fl ue and 1" clearance at the sides and bottom until the fl ue penetrates the outside wall. A minimum 1" clearance all
around the fl 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 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 outer wall.

When installing the appliance as a rear vent unit, the 90° or 45° transition elbow
attached directly to the rear of the unit is NOT INCLUDED in the following criteria and
calculations, and unless specifi cally 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 36” (914 mm). See Figure 22.

VENT INSTALLATION

HORIZONTAL TERMINATION CONFIGURATION

(Continued)

• If a 90° elbow is used in the horizontal vent run (level height
maintained) the horizontal vent length is reduced by 36".
See Figures 21 and 22, page 20. 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. See Figure 16, page 18.

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 26.

• Do not back fi ll 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.

VENT INSTALLATION

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 30 to avoid cutting load bearing
members.

Roof

Flashing

For optimal flame appearance, a restrictor disk is necessary on straight
vertical runs of 20' of more.

• Runs may not incorporate elbows.

• The disk is part number 45D0551 and is included in instal­lation manual packet.

• Drop the disk into a 4" inner collar before installing the first
section of flue or install at the last section before installing the
termination.

• An additional disk may be installed on runs of 35' or more.
Rotate disks perpendicular to each other.

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 13, page 20.

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.

hole as a center point The opening should be framed to 91/2"x91/2"
(241mm x 241mm) inside dimensions as shown in Figure 32using
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 31. Otherwise, install
firestop below the framed hole. See Figure 32.

2. Assemble the desired lengths of pipe and elbows necessary to
reach from the burner system flue up through the firestop. Be sure
pipe and elbow connections are fully twist-locked. See Figure

15, page 18.

" (241mm x 241mm) hole must be measured on the horizontal. Actual length may be larger
depending on the pitch of the roof. There must be a 1" minimum clearance from the vent pipe to combustible materials.
(Insulation should be considered a combustible material).

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 28, page 23. Whenever possible, use 45° elbows instead of
90° elbows. The 45° elbow offers less restriction to the fl ow of the fl ue 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 building code requirements.

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 fi rst fl oor, 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 fi ll any of the
required clearance spaces with insulation.

CATHEDRAL CEILING INSTALLATION

1. Remove shingles or other roof covering as necessary to cut the rectangular hole for the support box. Mark the outline of
the cathedral ceiling support box on the roof sheathing using the locating hole as a center point.

2. Cut the hole 1/8" larger than the support box outline. See Figure 32.

3. Lower the support box through the hole in the roof until the bottom of the box extends at least 2" below the ceiling. See
Figure 32. Align the support box vertically and horizontally using a level. Temporarily tack the support box in place
through the inside walls and into the roof sheeting.

4. Using tin snips, cut the support box from the top corners down to the roof line and fold the resulting flaps over the roof
sheeting. See Figure 33. Apply a bead of non-hardening, mastic around the top edges of the support box to make a seal
between the box and the roof. Nail in place with roofing nails. Remove any combustible material that might be inside
the support box.

5. Complete the cathedral ceiling installation by following the same procedures outlines in steps 2 through 6 for Flat Ceiling
Installation, page 24 and above.

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 for your gas type or conversion kit.

INSTALLING GAS PIPING TO FIREPLACE / BURNER SYSTEM LOCATION

INSTALLATION ITEMS NEEDED

Before installing fireplace and burner system, 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* • Sediment trap (recommended)

• Tee joint • Pipe wrench

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

1

* A CSA design-certified equipment shutoff valve with

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

CLEANING AND MAINTENANCE

Turn off gas before servicing fi replace. It is recommended that a qualifi ed service
technician perform these check-ups at the beginning of each heating season

WARNING

BURNER, PILOT AND CONTROL COMPARTMENT

Keep the control compartment, logs, and burner areas surrounding the logs clean by vacuuming or brushing at least twice
a year. Make sure the burner porting, pilot air opening and burner air opening are free of obstructions at all times.

Thermocouple

PILOT FLAME

The flames from the pilot should be visually checked as soon as the
heater is installed and periodically during normal operation. The pilot

flame must always be present when the fireplace is in operation. See
Figure 61. The pilot flame has three distinct flames, one engulfing the

thermopile, one engulfing the thermocouple, and the other reaching
to the main burner.

Thermopile

BURNER

Inspect area around the injector. Remove any lint or foreign material
with a brush or vacuum.

BURNER FLAME

The flames from the burner should be visually checked
as soon as the heater is installed and periodically during
normal operation. In normal operation, at full rate, and after
operating for about 15 to 30 minutes, the flame should be
yellow and slightly taller than the rear log. See Figure 62.

If the flame is blue and only in the center, turn off unit and
let cool. After unit is cool, remove logs and check to make
sure the back holes in the burner are not covered with rock
wool. If the back holes are clear, add more rock wool to the
center of the burner. Replace logs.
