IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

It is normal for fireplaces fabricated of steel to give off
some expansion and/or contraction noises during the
start up or cool down cycle. Similar noises are found
with your furnace heat exchanger or car engine. It is
not unusual for your gas fireplace to give off some odor
the first time it is burned. This is due to the manufactur­ing process.

Please ensure that your room is well ventilated

-open all windows.

It is recommended that you burn your fireplace for at
least four (4) hours the first time you use it. If the
optional fan kit has been installed, place the fan switch
in the “OFF” position during this time.

WARNING: When purging the gas line, the glass
front must be removed.

The embers supplied with your fireplace are made
from a high grade rock wool and should be
handled carefully. Wash your hands immediately
after touching to avoid irritation. The embers must
be placed correctly in order to function properly.

fittings. When a union is installed, provide easy
access in it’s placement for servicing. Refer to gas
specification for pressure details and ratings.

4. When a vertical section of gas pipe is required for
the installation, a condensation trap is needed. In
Canada see CSA - B149.1 for code details. See
the National Fuel Gas Code ANSI Z223.1/NFPA 54
in the USA.

5. For natural gas, a minimum of 3/8" iron pipe with a
gas supply pressure of 4.5" w.c. (from the gas
meter). Consult with local gas utility and ANSI
Z223.1/NFPA 54 if any questions arise concerning
pipe sizes.

6. Turn the gas supply to 'ON' and check for leaks.
DO NOT USE OPEN FLAME FOR THIS PUR­POSE. Use an approved leak testing solution.

7. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system at
test pressures in excess of 1/2psig (3.5 KPa).

8. The appliance must be isolated from the gas supply
piping system by closing its equipment shut off
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2psig (3.5KPa).

NOTE: The gas line connection may be made of 3/8"
minimum rigid pipe, 3/8” minimum copper pipe or an
approved flex connector. Since some municipalities
have additional local codes, it is always best to consult
your local authorities and the current CSA-B149.1

clearances must be observed. (Page 9, Fig. 10)

NOTE: Local codes may require different clearances.
It is recommended that the termination not be located

within 24" (305mm) of garden sheds, fences, decks,
utility buildings or other obstructions.

Do not locate termination cap where excessive snow or
ice build up may occur. Be sure to check vent termina­tion area after snow falls and clear to prevent acciden­tal blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.

This appliance has a "special vent system". Check with
local codes or in the absence of same, with CSA
B149.1 installation codes in Canada, or the current
National Fuel Gas Code ANSI Z223.1/NFPA 54 in the
USA, regarding special vent termination clearances.

2. Temco TDV series 4” x 7” dia. rigid vent.

3. Simpson Dura-Vent GS series 4” x 6⁵⁄₈” dia. vent.

4. Security Secure Vent series 4” x 6⁵⁄₈” dia. vent.
Review general venting information in this manual, and

information packed with the venting prior to starting the
installation of the fireplace.

• Termination shall not be recessed into a wall or

siding.

• Horizontal sections must maintain a minimum 1/4”

rise per linear foot of horizontal run.

• Combustible clearances from any horizontal vent

pipe area must be 2” (51mm) from top of vent, and
1” (25mm) from sides and bottom.

• Clearance to combustibles from vertical pipe sur-

Flex Venting

• Flex vent shall use the spacer springs as included

every foot to ensure proper vent operation.

• The 4” x 7” flex system may be used for all sidewall

applications and vertical venting up to 35’ (10.7m).

• Flex shall be properly supported so there are no

sags in the system. Supports must be used at least
every 24” (610mm) on horizontal section and every
36” (914mm) on vertical. Wire or metal stripping
may be used to support the venting.

• For 4” x 7” flex, the 7” flex has an outside diameter

of 7¹⁄₂” (191mm) and if installed in a chase the
inside diameter of the chase should be 9¹⁄₂”
(241mm) minimum.

• Lengths of co-axial flex may be joined together

using a flex connector kit (GFPVCK) only, maximum
1 kit per installation.

An extension collar is included with side wall cap kits
to simplify the connection of the flex pipe to the fire­place. Refer to Page 13, Figure 22.

ATTENTION: Spacer springs must be installed when
installing flexible venting systems.

Wrap spacer spring around flex flue pipe and overlap
spring ends approximately 2” (610mm). Tie one end
over the other like a shoelace tie, then reverse direc­tion of spring ends. Lift up hooped spring and slide
both spring ends underneath hooped spring. Spring
spacers should be spaced at approximately 12”
(305mm) intervals for the length of pipe system. Once
the springs are placed around the flue pipe, slide the
flue section with spacer springs into the outer flex pipe.

Horizontal Vent Kits
♦ CDV-HSK (Round Termination Cap)

The vent starter kit contains the following:

• Horizontal termination

• Wall thimble

• 36" of 7" x 4" flex with spacers and clamps.

• Extension collar

♦ HFTK (Trapezoid Termination Cap)

The vent starter kit contains the following:

• Horizontal termination

• Wall thimble

• Extension collar

NOTE: HIGH WIND AREAS All termination caps are
tested and certified for wind conditions up to 40 mph
(64 k/h).

A Vinyl Extension Frame Kit No. VEF is required for all
installations where vinyl siding is used with the HFTK
Kit or HSQ47 Horizontal Vent Termination. If a Vinyl
Extension Frame Kit No. VEF is used, measure to
outside surface of wall without siding and add 2 addi­tional inches (51mm) to the venting length.

A brick extension kit No. BEF is available to extend the
horizontal vent terminal HSQ47 or HFTK kit terminal
beyond the brick surface. If the BEF extension is used,
measure to the outside surface of the framed wall and
add 4 additional inches to the venting length.

Sidewall (Horizontal) Venting

For side wall (Horizontal) venting, this appliance is
approved for use with a 7" x 4" flexible venting system
with spacers.

Clearance to combustible material from the pipe is 1"
(25mm). Sides and bottom, 2” clearance from the top.
Note: O.D. of pipe is 7¹⁄₂" (191mm).

Flex Vent Offsets

Each installation assumes the use of (1) 45° (bend)
starting off top of unit.

To determine the amount or length of flex vent you
need for a given installation, add the total offset dimen­sion to the total rise needed. Then add 1’ (305mm) for
every 45° bend and/or 2’ (610mm) for each 90° bend.

No more than (4) 90° and (2) 45° offsets are to be used
per installation. Vent terminal cap location should be in
accordance with the Venting Graph chart and the
Vertical Termination Location information.

1. Measure the total wall thickness. Determine whether
or not the thimble extension is needed. If the com­bustible wall depth is over 5” (127mm), the exten­sion should be used. (Fig. 19)

2. Assemble wall thimble with thimble extension flange
to top. Mate thimble to wall plate with the four tabs
provided. Bend tabs over to secure. (Fig. 19)

3. Install the wall thimble assembly through the framed
opening so the firestop plate is on the interior wall.
(Fig. 20) Telescope section should extend all the
way through wall.

4. Step 1: Apply Mill-Pac to 4” flue inner pipe on cap.
Step 2: Connect 4” flex flue to flue on cap with

band clamp.
