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. Consideration should be given to
traffic ways, furniture, draperies, etc., due to
elevated surface temperatures (
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.

Step 3. INSTALL THE VENT SYSTEM
General Information
These instructions should be used as a guideline and do not supersede local codes in any
way. Install vent 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 and B149.2 in Canada.
These fireplaces are designed, tested
and listed for operation and installation
with, and only with, Secure Vent™ Direct
Vent System Components, Secure Flex™
Flexible Vent Components manufactured
by Security Chimneys International and
Z-FLEX™ Model GA Venting Systems
listed to UL1777 and ULCS635 manufactured by Flexmaster Canada Limited.
These approved vent system components
are labeled for identification. DO NOT
use any other manufacturer's vent components with these appliances.
These fireplaces must be vented directly
to the outside.
Determine the venting for the appliance. If the
vent run will include at least 8 feet of vertical
rise, then install the second restrictor in the
appliance collar before connecting any vent
(Refer to
tor inside the fixed restrictor.
Note: The second restrictor is included within
the firebox.
Figure 12
Exhaust Vent
). Place the second restric-
Fixed Restrictor
The vent system may not service multiple
appliances, and must never be connected to a
flue serving a solid fuel burning appliance. The
vent pipe is tested to be run inside an enclosing 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 is shown in the tables on
page 26.
VERTICAL TERMINATION SYSTEMS (ROOF)
Figures 13, 17 and 23 through 25 on pages
12, 14 and 15
and their associated Vertical
Vent Tables illustrate the various vertical venting configurations that are possible for use
with these appliances. Secure Vent pipe 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-1 B149 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 4
on page 6 ).

Vertical (Offset) Installation
Analyze the vent routing and determine the
quantities of vent sections and number of
elbows required. Refer to Vertical Vent Fig-
ures and Tables on page 14 and 15 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 11 for an aid in selecting length
combinations. Elbows are available in 90° and
45° configurations. Refer to
SV4.5E45 and SV4.5E90 elbow dimensional
specifications.

mm), 22-1/2" (572 mm), 34-1/2" (876 mm)
and 461/2" (1181 mm) net section lengths
are available. 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.
