devrait être installé dans un endroit où il y a
peu de circulation et loin du mobilier et des
tentures (Figure 3).

The location should also be free of electrical,
plumbing or other heating/air conditioning
ducting.

These direct-vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fireplace. Utility
shelves like these are commonly used for locat­ing television sets and decorative plants.

VERTICAL VENT
(Top Vent Application)

Be aware that this is a heat producing ap­pliance. Objects placed above the unit are
exposed to elevated temperatures.

Do not insulate the space between the ap­pliance and the area above it (see Figure 8).

The minimum height from the base of the appli­ance to the underside of combustible materials
used to construct a utility shelf in this fashion
is shown in Figure 8.

The appliance must be mounted on a fully sup­ported base extending the full width and depth of

*NOTE: 3" (75 mm) above any horizontal/inclined vent component.

**NOTE: See Page 9, Step 1 for clearance requirements to the nailing
flange located at each side of the unit and any screw heads adjacent to it.

Hearth Extension - A hearth extension is not required with this appliance.

If a hearth extension is used, do not block the lower control compartment
door. Any hearth extension used is for appearance only and does not have
to conform to standard hearth extension installation requirements.

Shelf Height - To provide for the lowest possible shelf surface, use the

alternate rear vent outlet, the venting attached to the top vent should be
routed in a way to minimize obstructions to the space above the appliance.

Do not insulate the space between the appliance and the area above
it (see Figure 8). The minimum height from the base of the appliance to

the underside of combustible materials used to construct a utility shelf in
this fashion is shown in Figure 8.

Wall Finishes / Surrounds / Mantels

NOTE: Combustible wall finish materials and/or surround materials must not
be allowed to encroach the area defined by the appliance front face (black
sheet metal). Never allow combustible materials to be positioned in front

of or overlapping the appliance face (see Figures 63a and 64 on Page 34).

Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance face with these exceptions: they must not
cover any portion of the removable glass panel or control compartment.

Vertical installation clearances to combustible mantels vary according
to the depth of the mantel. See Figure 9. Mantels constructed of non­combustible materials may be installed at any height above the appliance
opening; however, do not allow anything to hang below the fireplace hood.

Minimum clearance requirements include any projections such as shelves,
window sills, mantels, etc. above the appliance.

NOTE: We recommend the use of high temperature paint (rated 175° F
or higher) on the underside of the mantel.

Warnings.

Step 1. FRAMING

Frame these appliances as illustrated in Figures
13 and 14 on Pages 12 and 13 (Figure 15

applies to corner framing installations only).
All framing details must allow for a minimum
clearance to combustible framing members as
shown in Table 5 on Page 10.

If the appliance is to be elevated above floor level,
a solid continuous platform must be constructed
below the appliance.

Headers may be in direct contact with the
appliance top standoff spacer (Figure 12),
maintaining the 4" clearance to the fireplace top,

but must not be supported by them or notched
to fit around them. All construction above the
appliance must be self-supporting. DO NOT use
the appliance for structural support.

The fireplace should be secured to the side
framing members using the unit's side nailing
flanges - one top and bottom on each side of
the fireplace front. See Figure 13. Use 8d nails
or their equivalent.

SIDE NAILING FLANGES

Bend out the appropriate nailing flanges for
the drywall/finish material to be used. Nailing
flanges are provided for flush framing, 1/2" and
5/8" framing depths (see Figure 13).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line to the left side
of the appliance as shown in Figure 16. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. All appliances
are factory-equipped with a flexible gas line
connector and 1/2" shutoff valve. (See Figure
50 on Page 28).

Figure 16 - Route Gas Line

Proper Sizing of Gas Line

Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CGA-B149.1

- latest edition (Canada).

Never use galvanized or plastic pipe. Refer
to Table 6 for proper sizing of the gas sup­ply line, if black iron pipe is being used. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. We recommend
that a qualified individual such as a plumber or
gas fitter be hired to correctly size and route
the gas supply line to the appliance. Installing
a gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualified should attempt sizing
or installing gas piping.

NOTES:

• All appliances are factory-equipped with a
flexible gas line connector and 1/2" shutoff
valve (see Figure 50 on Page 28).

• See Massachusetts Requirements on Page
4 for additional requirements for installations
in the state of Massachusetts in the USA.

• The gas supply line should Not be connected
to the appliance until Step 7 (Page 27).

• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane

resistant compounds are used in propane
applications. Be very careful that the pipe

compound does not get inside the pipe.

• It is recommended to install a sediment
trap in the supply line as close as possible
to the appliance. Appliances using Propane
should have a sediment trap at the base of
the tank.

Propane

Gas

• Check with local building official for local
code requirements (i.e. are below grade
penetrations of the gas line allowed?, etc).

IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.

Step 4. INSTALL THE VENT SYSTEM

General Information

These instructions should be used as a
guideline and do not supersede local codes
in any way. Install venting according to local
codes, these instructions, the current National
Fuel Gas Code (ANSI-Z223.1) in the USA or
the current standards of CAN/CGA-B149.1
in Canada.

Ensure clearances are in accordance with
local installation codes and the requirements
of the gas supplier.

Dégagement conforme aux codes d'installation
locaux et aux exigences du foumisseunde gaz.

Use only approved venting components.
See Approved Vent Components on

Page 2.

These fireplaces must be vented directly
to the outside.

The vent system may not service multiple
appliances, and must never be connected to a
flue serving a separate solid fuel burning appli­ance. The vent pipe is tested to be run inside
an enclosed wall (such as a chase). There is
no requirement for inspection openings in the
enclosing wall at any of the joints in the vent pipe.

Select Venting System - Horizontal or Vertical

With the appliance secured in framing, determine
vent routing and identify the exterior termina­tion location. The following sections describe
vertical (roof) and horizontal (exterior wall)
vent applications. Refer to the section relating
to your installation. A list of approved venting

components are shown on Pages 34 and 35.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 23 on Page 16 and Figures 29 through
33 on Pages 18 and 19 and their associated

Vertical Vent Tables which illustrate the various
vertical venting configurations that are possible
for use with these appliances. Secure Vent
applications are shown in these Figures; Secure

®

Flex

pipe may also be used. A Vertical Vent
Table summarizes each system’s minimum and
maximum vertical and horizontal length values
that can be used to design and install the vent
components in a variety of applications.

Both these vertical vent systems terminate
through the roof. The minimum vent height
above the roof and/or adjacent walls is speci­fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN/CGA-B149.1 installation code)
by major building codes. Always consult your
local codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to

Figure 5 on Page 6).

Vertical (Straight) Installation

(Figure 20)

Determine the number of straight vent sec­tions required. 4-1/2" (114 mm), 10-1/2" (267
mm), 22 -1/2" (572 mm), 34-1/2" (876 mm)
and 46-1/2" (1181 mm) net section lengths
are available (see Tables on this page and
Pages 34 and 35 - Vent Sections). Plan the
vent lengths so that a joint does not occur at
the intersection of ceiling or roof joists. Refer
to the Vent Section Length Chart.

Vertical (Offset) Installation

Analyze the vent routing and determine the
quantities of vent sections and number of elbows
required. Refer to Vertical Vent Figures and
Tables on Pages 18 and 19 to select the type
of vertical installation desired. Vent sections
are available in net lengths of 4-1/2" (114 mm),
10-1/2" (267 mm), 22 -1/2" (572 mm), 34-1/2"
(876 mm) and 46-1/2" (1181 mm). Refer to the
Vent Section Length Chart on Page 15 for an
aid in selecting length combinations. Elbows are
available in 90° and 45° configurations. Refer
to Figure 24 on Page 17 for the SV4.5E45 and
SV4.5E90 elbow dimensional specifications.

Where required, a telescopic vent section
(SV4.5LA) may be used to provide the installer
with an option in installing in tight and confined
spaces or where the vent run made up of fixed
length pieces develops a joint in a undesirable
location, or will not build up to the required
length. The SV4.5LA Telescopic Vent Section
has an effective length of from 1-1/2" (38 mm)
to 7-1/2" (191 mm). The SV4.5LA is fitted with
a locking inclined channel end (identical to a
normal vent section component) and a plain end
with 3 pilot holes. Slip the plain end over the
locking channel end of a standard SV4.5 vent
component the required distance and secure
with three screws.

Maintain a minimum 1" (25 mm) clearance to
combustible materials for all vertical elements.
Clearances for all horizontal elements are 3"
(76 mm) on top, 1" (25 mm) on sides and 1"
(25 mm) on the bottom.

A. Frame ceiling opening - Use a plumb line

from the ceiling above the appliance to locate
center of the vertical run. Cut and/or frame an
opening, 10-1/2" x 10-1/2" (267mm x 267mm)
inside dimensions, about this center mark
(Figure 20).

All of the appliances covered in this document
are fitted with collars having locking inclined
channels. The dimpled end of the vent com­ponents fit over the appliance collar to create
the positive twist lock connection.

Align the dimple (four places) of
the upper vent section with the
opening of the locking incline
channel on the lower vent section
or appliance collar. Twist vent
component clockwise to engage
and seal until arrow and dimple

adjusting the radial alignment until the four
locking dimples are aligned with the inlet of
the four inclined channels on the collar (refer to
Figure 22). Push the vent component against
the collar until it fully engages, then twist the
component clockwise, running the dimples
down and along the incline channels until they
seat at the end of the channels. The unitized
design of the Secure Vent
engage and seal both the inner and outer pipe
without the need for sealant or screws. If desired
a #6 x 1/2" screw may be used at the joint, but
it is not required as the pipe will securely lock
when twisted.

appliance collar. Attach in the same manner as
you would a vent section.

D. Install firestop/spacer at ceiling - When
using Secure Vent, use SV4.5VF firestop/spacer
at ceiling joists; when using Secure Flex, use
SF4.5VF firestop/spacer. If there is living space
above the ceiling level, the firestop/spacer must
be installed on the bottom side of the ceiling.
If attic space is above the ceiling, the firestop/
spacer must be installed on the top side of
the joist. Route the vent sections through the
framed opening and secure the firestop/spacer
with 8d nails or other appropriate fasteners at
each corner. Remember to maintain 1" (25

mm) clearance to combustibles, framing
members, and attic or ceiling insulation
when running vertical chimney sections.
Attic insulation shield (96K94) may be used
to obtain the required clearances indicated
here. See installation accessories table on
Pages 34 and 35. The gap between the vent
pipe and a vertical firestop can be sealed with
non-combustible caulking.

E. Support the vertical vent run sections -

Note - Proper venting support is very important.
The weight of the vent must not be supported
by the fireplace in any degree.

Support the vertical portion of the venting
system every 8 feet (2.4m) above the fireplace
vent outlet. One method of support is by utiliz­ing field provided support straps (conventional
plumber's tape). Secure the plumber's tape to
the framing members with nails or screws. Loop
the tape around the vent, securing the ends of
the tape to the framing. If desired, sheet metal
screws #6 x 1/2" length may be used to secure the
support straps to the vent pipe. See Figure 23.

C. Attach vent components to each other - Other
vent sections may be added to the previously
installed section in accordance with the require­ments of the vertical vent figures and tables.
To add another vent component to a length of
vent run, align the dimpled end over the inclined
channel end of the previously installed section,
adjusting the radial alignment until the four
locking dimples are aligned with the inlets of
the four incline channels of the previous section.

Push the vent component against the previous
section until it fully engages, then twist the
component clockwise running the dimples down
and along the incline channels until they seat at
the end of the channels.This seating position

is indicated by the alignment of the arrow and
dimple as shown in Figure 22.

F. Change vent direction to horizontal/inclined
run - At transition from or to a horizontal/in-

clined run, install the SV4.5E45 and SV4.5E90
elbows in the same manner as the straight vent
sections. The elbows feature a twist section to
allow them to be routed about the center axis
of their initial collar section to align with the
required direction of the next vent run element.

Twist elbow sections in a clockwise direction
only so as to avoid the possiblity of unlocking
any of the previously connected vent sections.

See Figure 24.

G. Continue installation of horizontal/inclined
sections - Continue with the installation of the

straight vent sections in horizontal/inclined run
as described in Step C. Install support straps
every 5' (1.52 m) along horizontal/inclined vent
runs using conventional plumber’s tape. It is

very important that the horizontal/inclined run
be maintained in a straight (no dips), slightly
elevated plane. The recommended incline is
approximately 1/4" per foot (20 mm per me­ter) horizontal, in a direction away from the
fireplace. Use a carpenter’s level to measure

from a constant surface and adjust the support
straps as necessary.

It is important to maintain the required clear­ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 3" (76 mm) at the top,
1" (25 mm) at sides, and 1" (25 mm) at the
bottom for all horizontal/inclined runs.

I. Install the roof flashing - Extend the vent
sections through the roof structure. Install the
roof flashing over the vent section and posi­tion such that the vent column rises vertically
(use carpenters level) (Figure 26). Nail along
perimeter to secure flashing or adjust roofing to
overlap the flashing edges at top and sides only
and trim where necessary. Seal the top and both
sides of the flashing with waterproof caulking.

Figure 27

K. Install the vertical termination - The final
step involves installation of the SV4.5CGV-1
Vertical Termination. Extend the vent sections
to the height as shown in the "Vertical vent ter­mination section" on Page 6. The SV4.5CGV-1
Vertical Termination (Figure 28) installs in the
exact same fashion as any other Secure Vent®
section. Align the termination over the end of
the previously installed section, adjusting the
radial alignment until the four locking dimples
of the termination are aligned with the inlets of
the four incline channels of the last vent section.
Push the termination down until it fully engages,
then twist the termination clockwise running the
dimples down and along the incline channels
until they seat at the end of the channels.

H. Frame roof opening - Identify location for
vent at the roof. Cut and/or frame opening per
Roof Framing Chart and Figure 25.

Figure 26

J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the
vent/flashing joint. See Figure 27. Loosen the
storm collar screw. Slide collar down until it
meets the top of the flashing. Tighten the adjust­ing screw. Apply non-combustible caulking or
mastic around the circumference of the joint
to provide a water tight seal.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 28

If the vent system extends more than 5' (1.5
m) above the roof flashing, stabilizers may be
necessary. Additional screws may be used at
section joints for added stability. Guide wires
may be attached to the joint for additional sup­port on multiple joint configurations.

positive twist lock connection, (refer to Figure 22

on Page 16). All of the appliances covered in this
document are fitted with collars having locking
inclined channels. The dimpled end of the vent
components fit over the appliance collar to create
the positive twist lock connection.

A. Plan the vent run -
Analyze the vent routing and determine the types
and quantities of sections required 4-1/2" (114
mm), 10-1/2" (267 mm), 22 -1/2" (572 mm), 34­1/2" (876 mm) and 46-1/2" (1181 mm) net section
lengths are available. It is recommended that you
plan the venting so that a joint does not occur in the
ceiling or roof joists. Allow for elbows as indicated
in Figure 24 on Page 17.

Maintain a minimum 1" (25 mm) clearance to
combustibles on the vertical sections. Clearances
for the horizontal runs are; 3" (76 mm) on top, 1"
(25 mm) on sides, and 1" (25 mm) at the bottom.

B. Frame exterior wall opening -

Locate the center of the vent outlet on the ex­terior wall according to the dimensions shown
in Figure 14 on Page 12. Cut and/or frame an
opening, 10-1/2" x 12 -1/8" (267 mm x 308mm)
inside dimensions, about this center.

C. Frame ceiling opening - If the vertical route
is to penetrate a ceiling, use plumb line to locate
the center above the appliance. Cut and/or frame
an opening, 10-1/2" x 10-1/2" (267 mm x 267
mm) inside dimensions, about this center (refer
to Figure 21 on Page 16).

D. Attach vent components to appliance - To
attach a vent component to the appliance collar,
align the dimpled end over the collar, adjusting the
radial alignment until the four locking dimples are
aligned with the inlets of the four incline channels
on the collar (refer to Figure 22 on Page 16).

Push the vent component against the collar until it
fully engages, then twist the component clockwise,
running the dimples down and along the incline
channels until they seat at the end of the channels.

The unitized design of the Secure Vent compo­nents will engage and seal both the inner and
outer pipe elements with the same procedure.
Sealant and securing screws are not required.

NOTE: An elbow may also be attached to the
appliance collar. Attach in the same manner as
you would a vent section.

E. Attach vent components to each other - Other
vent sections may be added to the previously
installed section in accordance with the require­ments of the vent tables. To add another vent
component to a length of vent run, align the
dimpled end of the component over the inclined
channel end of the previously installed section,
adjusting the radial alignment until the four lock­ing dimples are aligned with the inlets of the four
incline channels of the previous section. Push
the vent component against the previous section
until it fully engages, then twist the component
clockwise running the dimples down and along
the incline channels until they seat at the end of
the channels.This seating position is indicated

by the alignment of the arrow and dimple as
shown in Figure 22 on Page 16.

F. Install firestop/spacer at ceiling -

When using Secure Vent, use SV4.5VF firestop/
spacer at ceiling joists; when using Secure Flex,
use SF4.5VF firestop/spacer. If there is living
space above the ceiling level, the firestop/
spacer must be installed on the bottom side of
the ceiling. If attic space is above the ceiling,
the firestop/ spacer must be installed on the
top side of the joist. Route the vent sections
through the framed opening and secure the
firestop/spacer with 8d nails or other appropri­ate fasteners at each corner. The gap between
the vent pipe and a firestop can be sealed with
noncombustible caulking.

Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.

G. Support the vertical run sections -

On the vertical run, support the venting sys­tem every 8 feet (2.4m) above the fireplace
vent outlet with field provided support straps
(Plumber's tape). Attach the straps to the vent
pipe and secure to the framing members with
nails or screws. See Figure 23 on Page 16.

H. Change vent direction - At transition from or
to a horizontal/inclined run, install the SV4.5E45
and SV4.5E90 elbows in the same manner as
the straight vent sections. The elbows feature
a twist section to allow them to be routed about
the center axis of their initial collar section to
align with the required direction of the next
vent run element. Twist elbow sections in a

clockwise direction only so as to avoid the
possiblity of unlocking any of the previously
connected vent sections. See Figure 24 on

Page 17.

I. Continue installation of horizontal/inclined
sections - Continue with the installation of the

straight vent sections in horizontal/inclined run
as described in Step E. Install support straps
every 5 ft. (1.52 m) along horizontal/inclined
vent runs using conventional plumber’s tape.
See Figure 34. It is very important that the

horizontal/inclined run be maintained in a
straight (no dips), slightly elevated plane.
The recommended incline is approximately
1/4" per foot (20 mm per meter) horizontal,
in a direction away from the fireplace. The
rise per foot run ratios that are smaller are
acceptable all the way down to at or near
level. Use a carpenter’s level to measure

from a constant surface and adjust the support
straps as necessary.

It is important to maintain the required clear­ances to combustibles: 1" (25 mm) at all
sides for all vertical runs; and 3" (76 mm) at
the top, 1" (25 mm) at sides, and 1" (25 mm)
at the bottom for all horizontal/inclined runs

J. Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent at the exterior wall. Prepare an opening
as described in Step B. Assemble the vent
system to point where the terminus of the last
section is within 7" (178 mm) to 11-1/4" (286
mm) inboard of the exterior surface to which
the SV4.5 HT termination is to be attached, see
Figure 35. If the terminus of the last section
is not within this distance, use the telescopic
vent section SV4.5LA, as the last vent section.
For wall thicknesses greater than that shown in
Figure 36, refer to Table 8 on Page 22. This table
lists the additional venting components needed
(in addition to the termination and adaptor) for
a particular range of wall thicknesses.

K. Attach termination adaptor - Attach the
adaptor (adaptor - SV4.5RCH - provided with the
termination) to the vent section or telescoping
vent section), elbow or appliance collar as shown
in Figures 35 and 36 in the same manner as
any SV4.5 vent component (refer to Step E).

L. Install Firestop/Spacer at exterior wall

- When using the square termination, install

SV4.5HF (Secure Vent®), SF4.5HF (Secure
Flex®) Firestop/Spacer over the opening at the
exterior side of the framing, long side up, with
the 3" spacer clearance at the top as shown in
Figure 35, and nail into place. The Firestop/
Spacer may also be installed over the opening at
the interior side of the framing. The gap between
the vent pipe and a firestop can be sealed with
noncombustible caulking.

M. Install the desired termination -

1. Install the square termination (SV4.5HT-2)-

For the last step , from outside the exterior
wall, slide the collars of the termination onto
the adaptor (the outer over the outer and the
inner inside the inner) until the termination
seats against the exterior wall surface to which
it will be attached. Orient the housing of the
termination with the arrow pointed upwards.
Secure the termination to the exterior wall. The

horizontal termination must not be recessed
into the exterior wall or siding by more than

the 1-1/4" (32 mm) as shown in Figure 36.

IMPORTANT: The vent termination is hot
while in operation and for a period of
time following the use of the fireplace.
To prevent contact with hot surfaces,
we recommend the use of a Termina-
tion Guard. See Page 35. This can be
purchased at your local dealer.

Horizontal terminations have been designed to perform in a wide range of weather
conditions. Our terminations meet or exceed industry standards.

When selecting the locations of your horizontal terminations, do not place the termination
where water from eaves and adjoining rooflines may create a heavy flow of cascading water
onto the termination cap. If the cap must be placed where the possibility of cascading water
exists, it is the responsibility of the builder to direct the water away from the termination
cap by using gutters or other means.

Take care to carefully follow the installation instructions for the termination, including the
use of silicone caulking where required.

Step 7. CONNECTING GAS LINE

Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure
50 illustrates two methods for connecting the
gas supply. The flex-line method is acceptable
in the U.S., however, Canadian requirements
vary depending on locality. Installation must
be in compliance with local codes. A sediment
trap is recommended in the gas piping within
the home to prevent moisture and debris in the
line from damaging the valve.

These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the direct vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. Refer to Figure
50 for flex line description. The flex line is rated
for both natural and propane gas. A manual
shut off valve is also provided with the flex line.

The gas control valve is located in the lower
control compartment.

To access the valve open the lower control
compartment door (see Figure 51) by lifting
up approximately 1/2" and then swinging the
door open. (The door is hinged at the bottom).
Remove the bottom compartment door by
sliding the hinge pin, located at the door’s left
side, to the right until it disengages from the
left corner post hole. Pull the door diagonally
to the left, away from the fireplace.

The millivolt control valve has a 3/8" (10 mm)
NPT thread inlet port. The electronic control
valve has a 1/2" (13 mm) NPT thread inlet
port and is fitted with a 1/2" x 3/8" (13 mm x
10 mm) NPT fitting.

(See Figure 47 on Page 24) -

An electrical outlet box is provided for the
installation of the FBK-100, FBK-200 forced air
blower kits. Electrical power must be provided
to this box to operate these blowers. Install the
blower kits according to the installation instruc­tions provided with the kits.

FBK-250 Blower Kit

(See Figure 47 on Page 26)

An electrical outlet box is provided for the
installation of the FBK-250 forced air blower
kit. Electrical power must be provided to this
box to operate these blowers. Install the blower
kit according to the installation instructions
provided with the kit.

NOTE: The tab connecting the receptacles of
the outlet box must be broken in FBK-100 and
FBK-200 blower kit applications. See Figure 49.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane
applications).

All codes require a shut-off valve mounted
in the supply line. The orientation of the
shut-off valve should face the front. Figure
50 illustrates two methods for connecting the
gas supply. A sediment Trap is recommended
to prevent moisture and debris in the gas line
for damaging the valve.

hood at all three ports (see Figure 52). Replace
logs if removed for pilot inspection.

To light the burner; turn “ON” the remote wall
switch and rotate the gas valve control knob
counterclockwise to the “ON” position (“ON”
will be at the top side of the valve).

Step 8. VERIFYING APPLIANCE OPERA­TION

28

WARNING

Never use an open flame to
check for leaks.

Turn on gas supply and test for gas leaks, us­ing a gas leak test solution (also referred to as
bubble leak solution).

NOTE: Using a soapy water solution is an
effective leak test solution but it is not recom­mended, because the soap residue that is left
on the pipes/fittings can result in corrosion
over time.

A. Light the appliance (refer to the lighting

instructions label in the control compartment
or in the Care and Operation Instructions
manual).

B. Brush all joints and connections with the gas

leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.

C. When the gas lines are tested and leak free,

be sure to rinse off the leak testing solution.

WARNING

• DO NOT attempt to install the
logs until the appliance instal­lation has been completed, the
gas line connected and tested
for leaks and the initial burner
operation has been checked
out.

•

The size and position of the log

set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result in
incomplete combustion, soot­ing, and poor flame quality.

•

Logs get very hot and will

remain hot up to one hour after
gas supply is turned off. Handle
only when logs are cool. Turn
off all electricity to the appli­ance before you install grate,
volcanic stone, vermiculite,
embers and logs.

•

This appliance is not designed

to burn wood. Any attempt to
do so could cause irreparable
damage to the appliance and
prove hazardous to your safety.

•

If logs are not installed accord-

ing to the log installation
instructions, flame impinge­ment and improper combustion
could occur and result in soot
and/or excessive production
of carbon monoxide (CO), a
colorless, odorless, toxic gas.

Step 4. Placement of Logs -

All top logs that rest on lower logs, do so over
notches, indents or nubs. Proper log placement
is critical to prevent sooting. Logs should be
placed in the gaps between the flame peaks and
should be positioned so they do not impinge
the flames.

Step 5. Position the individual logs as shown
in Figures 56 and 57. Logs should be placed
in the order shown. All logs that have notches
to fit over the grate tines should be positioned
with these notches directly against the grate.

Handle logs carefully to prevent breakage.

Proper log placement is critical to encourage
outstanding flame appearance and prevent
sooting. When positioned properly as shown,
logs will be positioned between flame peaks
and will not impinge any flames.

Step 11. BURNER ADJUSTMENTS

Flame Appearance and sooting

Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame.

When the appliance is first lit, the entire
flame may be blue and will gradually turn
yellowish-orange during the first 15 minutes
of operation. If the flame remains blue, or if
the flame is orange with evidence of sooting
(black tip), the air shutter opening may need
to be adjusted.

If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated by
black puffs developing at the tips of very long
orange flames. Sooting results in black deposits
forming on the logs, appliance inside surfaces
and on exterior surfaces adjacent to the vent
termination.

Sooting is caused by incomplete combustion
in the flames and lack of combustion air enter­ing the air shutter opening. To achieve a warm
yellowish-orange flame with an orange body
that does not soot, the shutter opening must be
adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, first check
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.

• The more offsets in the vent system, the larger
the air shutter opening will need to be.

• An appliance operated with the air shutter
opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.

• Propane models may exhibit flames which
candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.

The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

CAUTION

• Soot will be produced if the
air shutter is closed too much.
Any damage due to sooting,
resulting from improperly
setting the air shutter, is not
covered under the warranty.

• The air shutter door and
nearby appliance surfaces
are hot. Exercise caution to
avoid injury while adjusting
flame appearance.

1. Refer to Figures 59, 60 and 61 for proper

flame app earance. To adjust the flame, rotate
the adjustment rod toward the back or toward
the front of the fireplace (rod located in the
lower control area). Position the air shutter
to the factory setting as shown in the table
in Figure 62.

2. Light appliance (follow lighting procedure

on lighting label in control compartment or
see the Care and Operation Manual).

3. Allow the burner to operate for at least 15

minutes while observing the flame continu­ously to ensure that the proper flame ap­pearance has been achieved. If the following
conditions are present, adjust accordingly.

• If flame appears weak or sooty, adjust
the air shutter, incrementally, to a more
open position until the proper flame
appearance is achieved.

• If flame remains blue, adjust the air
shutter, incrementally, to a more closed
position until the proper flame appear­ance is achieved.

4. (Millivolt Models) Leave the control knob

(off/pilot/on) in the ON position and the
burner OFF/ON switch OFF (and remote
switches, if applicable).

5. When satisfied that the burner flame appear-

ance is normal, re-install the lower control
compartment door then proceed to finish
the installation.

Burn-in Period

During the first few fires of this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process. Depending on your
use, the burn-in period may take a few hours
or a few days.

KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.

If an optional blower is installed, Do Not turn
it on during the Burn-In period.

A white film may develop on the glass front
during the first few fires as part of the curing
process. The glass should be kept clean during
the first two weeks of use to prevent the film from
baking on (making it very difficult to remove).

MAINTENANCE

(See Maintenance Schedule, Page 54)

Refer to the maintenance schedule for maintenance
tasks, procedures, frequency and by whom they
should be performed. Always verify proper opera­tion of the appliance after servicing.

WARNING

Turn off gas and electrical power
to the fireplace and allow it to
cool before cleaning or servicing
the appliance.

CAUTION: Wear gloves and safety
glasses for protection while doing
required maintenance.

Verify proper operation after servicing.

S'assurer que l'appareil fonctionne adé­quatement une fois l'entretien terminé.

Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re­lighting, refer to the lighting instructions
in this manual. Instructions are also found
on a pull-out panel located in the control
compartment.

Always keep the appliance area clear
and free from combustible materials,
gasoline and other flammable liquids.

WARNING: Do not use abrasive cleaners
on glass. Never clean the glass when it
is hot.

The viewing glass should be cleaned periodi­cally to remove any build-up caused from the
following:

• During start-up, it is normal for condensa­tion to form on the inside of the glass (this
condensation and fog will usually disappear
in a few minutes). The moisture can cause
lint, dust and other airborne particles to cling
to the glass surface.

• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a film
on the glass.

• A white coating may form on the glass as a
result of impurities and minerals in the fuel.

It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present. The
following cleaning solutions are approved for
use to clean glass:

• Non-ammonia based household cleaner

• 50%-50% mix of white vinegar and water

• Gas fireplace/stove glass cleaner

Inspect Glass Gasket - Visually inspect the
gasket on the backside of the glass enclosure
panels. The gasket surface must be clean, free
of irregularities and seated firmly.

Replacing Logs

If the logs become damaged by accident or
improper handling and need replacement, use
only the proper replacement logs from manu­facturer (see Page 50 for ordering information).

Re-Install Embers and Logs

Carefully follow placement instructions on
Pages 46 through 47. All logs should fit
onto corresponding pins and/or log stop­pers. This will ensure a proper flame and safe
combustion.

Inspect Wiring

Refer to wiring diagrams on Page 50.

CAUTION: Label all wires prior to discon­nection when servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify proper operation after
servicing.

ATTENTION: Au moment de l'entretien
des commandes, étiquetez tous les fils
avant de les débrancher. Des erreurs
de cáblage peuvent entraîner un fonc­tionnement inadéquat et dangereux.

Inspect and clean all wire connections. Ensure
that there is no melting or damage. Inspection
should include:

• Terminals at the Valve

• OFF/ON Switch

• (Optional Control Switch) Wall Thermostat,
Remote Control or Remote Wall Switch Kit

Inspect Venting System

The appliance and venting system should be
thoroughly inspected before initial use and
at least annually by a qualified service techni­cian (inspection should include ensuring that
exhaust or intake passages are unobstructed
and vent components are properly assembled
and not damaged). Homeowner must contact

a qualified service technician at once if any
abnormal condition is observed.

If the venting system is disassembled for any
reason, a qualified service technician should
follow vent installation instructions for proper
reassembly and proper sealing of the venting
system components. However, more frequent
periodic inspections and cleanings should be
performed by the homeowner.

Cleaning Glass

(see front face assembly, Front Glass Enclosure
Panel, Removal and Installation on Page 45).

NOTE: Clean glass after first two weeks of
operation (after Burn-In period is over) and then
only when necessary and when the fireplace is
cool. Wipe surface with a clean, dampened, soft
cloth. Follow with a dry, soft towel as desired.
Take care not to scratch the glass surface.

44

Keep control compartment clean by vacuuming
or brushing at least twice a year. More frequent
cleaning may be required due to excessive lint
from carpeting, bedding materials, etc. It is
important that control compartments, burners
and circulating air passageways of the appliance
be kept clean.

Clean Logs And Burner

Carefully remove the logs (use care when han­dling the fiber logs, as they become quite fragile
after curing). Vacuum out any foreign matter
(lint, carbon, etc.) on the burner. Ensure the
burner ports are “open.” Remove any carbon
deposits from the under side of the logs using
a vacuum cleaner, or a soft bristled brush (i.e.
paint brush).

NOTE: Improper positioning of logs can create
carbon build-up and will alter the performance
of the appliance.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Inspect Burner Flame and Pilot Flame
Appearance

Periodically do a visual check of the burner
flame and the pilot flame. Ensure that the
burner flame appearance resembles the flame
shown in Figures 74 and 75 and as described
in Flame Appearance and Sooting on Page 48.
Refer to Figures 77 and 78 on Page 49 for
more information about the pilot flame appear­ance. Contact a qualified service technician at
once if any abnormal condition is observed.

Small Area Paint Touch-up

Only use a factory supplied paint kit for touch­ups. Paint is available at your local
Hearth Products dealer. Never attempt to paint
a hot fireplace.

Do not attempt to repaint the appliance until the
finish is completely cured (see Burn-In Period
on Page 41). If the surface later becomes
stained or marred, it may be lightly sanded
and touched up with spray paint.

• DO NOT attempt to install the logs

until the appliance installation
has been completed, the gas
line connected and tested for
leaks and the initial burner
operation has been checked out.

•

The size and position of the log

set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result
in incomplete combustion,
sooting, and poor flame quality.

•

Logs get very hot and will remain

hot up to one hour after gas
supply is turned off. Handle
only when logs are cool. Turn
off all electricity to the appliance
before you install grate, volcanic
stone, vermiculite, embers and
logs.

•

This appliance is not designed

to burn wood. Any attempt to
do so could cause irreparable
damage to the appliance and
prove hazardous to your safety.

•

If logs are not installed

according to the log installation
instructions, flame impingement
and improper combustion could
occur and result in soot and/or
excessive production of carbon
monoxide (CO), a colorless,
odorless, toxic gas.

Step 1. Remove front face assembly, hood,
and appliance front door (see Removing Glass
Encloslure panel on Page 45.

Step 2. Install decorative volcanic stone -
Sprinkle the decorative volcanic stone in a pleas­ing pattern. The volcanic stone should be placed
directly on top of the firebox bottom, along the
front and to the back at the right and left sides of
the burner. Position any optional ceramic fiber
liners before placing the stone. Logs should be
positioned after the volcanic stone.

NOTE: This appliance is provided with enough
Glowing Embers for several applications, do
not feel compelled to use all that is in a new
bag. For best glowing effect, replace the ember
material annually. Replacement Glowing Em­bers are available (Catalog Number 88L53).

Step 3. Separate the Glowing Ember
(Rockwool) into pieces about the size of a
quarter (Figure 72). Keep the pieces fluffed
up, not matted. Distribute these pieces over
the front surface of the burner, as shown in
Figure 71. Do not use more than is neces­sary. When properly positioned, the Glowing
Embers will cover approximately 65% of the
front burner and with no appreciable gaps or
openings. Ensure that the main burner ports
remain uncovered by the ember material.

Step 4. Placement of Logs -

All top logs that rest on lower logs, do so over
notches, indents or nubs. Proper log placement
is critical to prevent sooting. Logs should be
placed in the gaps between the flame peaks and
should be positioned so they do not impinge
the flames.

Step 5. Position the individual logs as shown in
Figure 73. Logs should be placed in the order
shown. All logs that have notches to fit over
the grate tines should be positioned with these
notches directly against the grate. Handle logs

carefully to prevent breakage.

Proper log placement is critical to encourage
outstanding flame appearance and prevent
sooting. When positioned properly as shown,
logs will be positioned between flame peaks
and will not impinge any flames.

BURNER ADJUSTMENTS

(QUALIFIED TECHNICIANS ONLY)

Flame Appearance and Sooting

Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange

in the body of the flame.

When the appliance is first lit, the entire flame
may be blue and will gradually turn yellowish­orange during the first 15 minutes of operation.
If the flame remains blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.

If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated by
black puffs developing at the tips of very long
orange flames. Sooting results in black deposits
forming on the logs, appliance inside surfaces
and on exterior surfaces adjacent to the vent
termination.

Sooting is caused by incomplete combustion
in the flames and lack of combustion air enter­ing the air shutter opening. To achieve a warm
yellowish-orange flame with an orange body
that does not soot, the shutter opening must be
adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, first check
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.

• The more offsets in the vent system, the larger
the air shutter opening will need to be.

• An appliance operated with the air shutter
opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.

• Propane models may exhibit flames which
candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.

The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

• Air shutter adjustment should
only be performed by a quali­fied professional service tech­nician.

• Ensure front glass panel are
in place and sealed during
adjustment.

CAUTION

• Soot will be produced if the
air shutter is closed too much.
Any damage due to sooting,
resulting from improperly
setting the air shutter, is not
covered under the warranty.

• The air shutter door and
nearby appliance surfaces
are hot. Exercise caution to
avoid injury while adjusting

in Figure 76.

2. Light appliance (follow lighting procedure

on lighting label in control compartment or
see the Pages 55 through 58.

3. Allow the burner to operate for at least 15

minutes while observing the flame continu­ously to ensure that the proper flame ap­pearance has been achieved. If the following
conditions are present, adjust accordingly.

• If flame appears weak or sooty, adjust
the air shutter, incrementally, to a more
open position until the proper flame
appearance is achieved.

• If flame remains blue, adjust the air
shutter, incrementally, to a more closed
position until the proper flame appear­ance is achieved.

4. Leave the control knob (off/pilot/on) in the

ON position and the burner OFF/ON switch
OFF (and remote switches, if applicable).

5. When satisfied that the burner flame appear-

ance is normal, re-install the lower control
compartment door then proceed to finish

TROUBLESHOOTING - MILLIVOLT GAS CONTROL SYSTEM

NOTE: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, if applicable), is
in the “ON” position.

IMPORTANT: Valve system troubleshooting should only be accomplished by a qualified service technician.

SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION

1. Spark igniter will not light pilot after

repeated triggering of igniter button.

WARNING: if the pilot will not light

after 1 minute of attempting, wait
for at least 5 minutes for gas to
clear before attempting again.

2. Pilot will not stay lit after carefully

following the lighting instructions.

3. Pilot burning, no gas to burner, Valve

knob “ON,” and the (standard) burner
OFF/ON switch is “ON." Read impor­tant note below.

IMPORTANT NOTE: If an optional

*remote switch is used for burner
operation, if the standard burner
OFF/ON switch is still installed on
appliance it must be in the "OFF"
position.

*Optional remote switch kits - wall

switch, thermostat or timer, or
remote control.

4. Frequent pilot/burner outage prob-

lem.

A. Defective igniter
(no spark at electrode).

B. Defective or misaligned electrode at pilot

(spark at electrode).

Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace igniter.

Using a match, light pilot. If pilot lights, turn off pilot
and trigger the igniter button again. If pilot lights, an
improper gas mixture caused the bad lighting and
a longer purge period is recommended. If pilot will
not light - check gap at electrode and pilot - should
be 1/8" to have a strong spark. If gap measures 1/8",
replace pilot (see Figure 77 on Page 49).

C. Gas supply pressure errant. Check inlet gas pressure. It should be within the limits

as marked on the rating plate.

D. Pilot orifice plugged. Clean or replace pilot orifice.
A. Defective pilot generator

(thermocouple).

Check pilot flame, it must impinge on thermocouple
(see Figure 77 on Page 49). Clean and/or adjust pilot
for maximum flame impingement on thermocouple.
Ensure that the connection between the valve and
thermocouple are tight and secure.

A. Wall switch or wires defective. Check wall switch and wires for proper connections.

Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires across wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.

B. Thermopile may not be generating suf-

ficient millivolts.

Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below
specified minimum.

C. Plugged burner orifice. Check burner orifice for blockage and remove.
D. OFF/ON Switch & *Remote Switch are in

the "ON" position resulting in excessive
resistance.

When turning on the burner using a *remote switch,
ensure that the standard OFF/ON switch is in the "OFF"
position. If both switches are in the ON position, it
may result in excessive resistance (& millivolt drain­age) and the burner may not come on.

A. Pilot flame may be too low or blowing (high)

causing the pilot/valve safety to drop out.

Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see Figure 77 on

Page 49).
