INTRODUCTION
These fireplaces are designed, tested and listed
foroperationandinstallationwith,andonlywith,
SecureVent™DirectVentSystemComponents,
SecureFlex™FlexibleVentComponentsmanu-
facturedbySecurityChimneysInternationaland
Z-Flex™ Model GA Venting Systems, listed to
UL1777 and ULCS635 manufactured by Flex-
master Canada Limited. These approved vent
system components are labeled for identifica-
tion. DONOTuseanyothermanufacturer'svent
components with these appliances.
Millivolt appliances are designed to operate
on natural or propane gas. A millivolt gas
control valve with piezo ignition system pro-
vides safe, efficient operation. There is no
optional blower with these units.
PACKAGING
The assembledvented gasfireplaceheater is
packaged with the folowing:
1 - The logs are packaged in a carton located
within the firebox.
2 - Onebagofvolcanicstonesislocatedinthe
bottom compartment.
3- One envelope containing the litera-
ture package, which consists of the
homeowner's manual, installation in-
structions,logsetsupplement,warranty,
gas access plate,screws (4) and gasket.
The envelope is located in the bottom
compartment.
4 - One vent restrictor, to be used as detailed
on page 10.
5 - One hood and one control compartment
coverand one45degree starter elboware
strapped to the top of the unit.

Electronic appliances are designed to operate
on natural or propane gas. An electronic inter-
mittent pilot ignition system provides safe, ef-
ficient operation. External electrical power is
recommended to operate these units. If the
systemoperates on linevoltagewith 3V adapt-
ers, two (2) "D" batteries can be used as a
backup in case of a power outage. The elec-
tronicappliancecanbeoperatedsolelywithtwo

LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns.However,ventsystemroutingtothe
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 ( Figure 2 ).
The location should also be free of electrical,
plumbingorotherheating/airconditioningduct-
ing. These direct vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fireplace. Utility
shelveslikethesearecommonlyusedforlocat-
ing television sets and decorative plants.

and components installed and pre-wired. Re-
move the shipping carton, exposing the front
glassdoor. Removethebottompanelbylifting
and pulling it towards the front.
Openthetwolatches(locatedunderthefirebox

Note: The nailing flanges, combustible members
and screw heads located in areas directly adjacent
to the nailing flanges, are EXEMPT from the 1”
clearance to combustible requirements for the
firebox outer wrapper. Combustible framing may be
in direct contact with the nailing flanges and may
be located closer than 1” from screw heads and the
firebox wrapper in areas adjacent to the nailing
flanges. Frame the opening to the exact dimensions
specified in the framing details of this manual.

Step 3. INSTALL THE VENT SYSTEM
General Information
Theseinstructionsshouldbeusedasaguide-
lineand donot supersedelocal codesin any
way. Install vent according to local codes,
theseinstructions, the currentNational 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

ponents with these appliances.

vent run will include at least 8 feet of vertical
rise, then install the second restrictor in the
appliance collar before connecting any vent
(Referto Figure12 ). Placethesecondrestric-
tor inside the fixed restrictor.
Note: The second restrictor is included within
the firebox.
The vent system may not service multiple

vent pipe is tested to be run inside an enclos-
ingwall(suchasachase).Thereisnorequire-
mentfor inspectionopeningsin theenclosing

Select Venting System - Horizontal or Vertical
With the appliance secured in framing, deter-
mine vent routing and identify the exterior
termination location. The following sections
describevertical(roof)andhorizontal(exterior
wall) vent applications. Refer to the section
relating to your installation. A list of approved
ventingcomponentsisshowninthetableson
page 26.
VERTICAL TERMINATION SYSTEMS (ROOF)

12, 14 and 15 and their associated Vertical
VentTablesillustratethevariousverticalvent-
ing configurations that are possible for use
with these appliances. Secure Vent pipe ap-
plications are shown in these figures; Secure
Flex pipe may also be used.
AVerticalVentTablesummarizeseachsystem’s
minimumandmaximumverticalandhorizontal
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 speci-
fiedinANSIZ223.1-(latestedition)(InCanada,
the current CAN-1 B149 installation code) by
major building codes. Always consult your
local codes for specific requirements. A gen-
eralguide to followisthe Gas VentRule(refer
to Figure 4 on page 6 ).
Vertical (Straight) Installation
Determine the number of straight vent sec-
tionsrequired.4-1/2"(114mm),10-1/2"(267
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.

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
