COLD CLIMATE INSULATION

Installation and Operation Instructions

900357-00, 06/2015

For cold climate installations, seal all cracks
around your appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which appliance rests, if floor is above
ground level. Gas line holes and other open­ings should be caulked or stuffed with unfaced
fiberglass insulation.

If the fireplace is being installed on a cement
slab in cold climates, a sheet of plywood or
other raised platform can be placed underneath
to prevent conduction of cold transferring to
the fireplace and into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk firestops.

LOCATION

In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important.

Due to high temperatures, the appliance
should be located out of traffic and away from
furniture and draperies (Figure 3).

En raison des températures élevées, l’appareil
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
the unit. The appliance may be located on or near
conventional construction materials. However,
if installed on combustible materials, such as
carpeting, vinyl tile or other combustible material
other than wood flooring, the appliance shall be

*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.

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).

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

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.

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.

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
