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.

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.
