INTRODUCTION
Theseventedgasheatersaresealedcombus-
tion, air circulating gas stoves designed for
residential applications. These appliances
must be installed with "Security Secure
VentTM" or "Simpson Dura Vent" brand vent
systems routed to the outside atmosphere
(other brands may not be used).
Millivolt appliances are designed to oper-
ate on natural or propane gas. A millivolt
gas control valve with piezo ignition system
provides safe, efficient operation. External
electrical power is required to operate the
optional blower if installed on these units.
Note: Installation and repair should be per-
formed by a qualified service person. The
appliance should be inspected annually by
a qualified professional service technician.
More frequent inspections and cleaningsmay
be required due to excessive lint from carpet-
ing, bedding material, etc. It is imperative
that the control compartment, burners and
circulating air passage ways of the appliance
be kept clean.
S'assurer que le brùleur et le compartiment
des commandes sont propres. Voir les
instructions d'installation et d'utilisation qui
accompagnent l'appareil.
Provideadequate clearances around air open-
ings and adequate accessibility clearance for
service and proper operation. Never obstruct
the front openings of the appliance.
These appliances are designed to operate
on natural or propane gas only.
These millivolt models come standard with
the manually-modulated gas valve; flame
appearanceandheatoutputcanbecontrolled
at the gas valve.
These appliances are designed as supple-
mental heaters. Therefore, it is advisable to
have an alternate heat source when installed
in a dwelling.

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. Considerationshould be given
to traffic ways, furniture, draperies, etc., due
to elevated surface temperatures.
Considerations Should Include:
• Existing Chimneys
• Aesthetic Considerations
• Roof Design (Rafter Locations and Roof Pitch)
• Room Traffic
• Proximity to Combustibles
• Proximity for Optimum Heat Transfer
• Electrical Wiring (if optional blower is installed)
The installation of this stove will require some
research. Once your options are determined,
consult with your localbuilding department who
will be able to give youthe necessary installation
requirements for your area (Is a building permit
required?, Rooms where installation may not
be allowed?, etc.).

IMPORTANT NOTE: If propane is used, be aware
that if the 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 or other malfunc-
tions). Any damage resulting from an improper
installation, such as this, is not covered under
the limited warranty.
Open both Latches as shown.

Make gas line connections. All codes require
a shut-off valve mounted in the supply line.
Figure 18 illustrates two methods for con-
necting the gas supply. The flex-line method
is acceptable in the U.S., however, Canadian
requirements vary depending on locality.
Installation must be in compliance with local
codes.

When first lighting the appliance, it will take
a few minutes for the line to purge air from
the appliance. Once purging is complete,
the pilot and burner will light and operate as
indicatedintheinstructionmanual.Subsequent
lightings of the appliance will not require such
purging. Inspect the pilot flame (remove logs,
if necessary, handling carefully).
Step 11. INSTALLING LOGS AND GLOW-
ING EMBERS
The packaged log set and bag of glowing
embers are located within the firebox of
the stove.
Installation Instructions:
Theseappliancesare equipped with a gas flex
line for use (where permitted) in connecting
the unit to the gas line. A gas flex line is
provided to aid in attaching the direct vent
appliance to the gas supply. The gas flex line
can only be used where local codes permit.
See Figure 18 for flex line description. The
flex line is rated for both natural and propane
gas. A manual shut off valve is also provided
with the flex line. The gas control valve is
located in the lower control compartment.
To access the valve, open the lower access
door. The millivolt control valve has a 3/8"
(10 mm) NPT thread inlet port fitting.

AIR PURGING PROCEDURES MUST PER-
FORMED BY A QUALIFIED TECHNICIAN
ONLY.
Purging Air from Supply Line
a. Turn gas supply line valve off.
b.Loosen setscrewatinlet pressuretap onupper
right of control valve (see Figure 30).
c. Turn gas supply line valve on.
d. When gas flows, turn supply valve off.
e. Close the inlet pressure tap.
Purging Air from Appliance
Purgeair from appliance by holding gascontrol
valve down in the pilot position until pilot will
light (see Figure 19). DONOT LIGHT A MATCH
IF YOU SMELL GAS. Light a match then allow
gas flow to pilot. If the Match “blows”, there is
air in the line (purge line). If the flame is straight
and tall, there is no gas pressure.
Figure 19
Carefully install the ember strip and seven-
piece log set into the firebox as shown in
these instructions. All logs should fit onto
corresponding pins and/or log stoppers.
This will ensure a proper flame and safe
combustion.
Note: If an optional Brick Liner Kit was purchased,
install it now, per instructions provided in kit
*A Sediment Trap is recom-
mended to prevent moisture
and debris in gas line from
damaging the valve.
WARNING
If logs are not installed accord-
ing to the directions shown here,
flame impingement and improper
combustion could occur and result
insootand/orexcessiveproduction
of carbon monoxide (CO), a color-
less, odorless, toxic gas.
1. Carefully place the ember strip as shown
in Figure 20. Ensure that it is pushed all the
way back in position (toward the sub-floor
front flange).

Turn on gas supply and test for gas leaks using a
gas leak test solution (also referred to as bubble
leaksolution). Note: Usingasoapy watersolution
(50% dish soap, 50% water) is an effective leak
test solution but it is not recommended, because
the soap residue that is left on the pipes/fittings
can result in corrosion over time.
A. Light the appliance (refer to the lighting
instructions provided in the Homeowner's
Care and Operation Instructions).
B. Brush all joints and connections with the gas
leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.
C. Whenthe gas lines aretested and leak freebe
sure to rinse off the leak testing solution,
D. Turn on burner then observe the individual
tongues of flame on the burner. Make sure
all ports are open and producing flame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.
Step 14. CHECKING APPLIANCE OPERA-
TION
With gas line installed run initial system
checkout before closing up the front of
the unit. Follow the pilot lighting instruc-
tions provided in the Homeowner's Care
and Operation Instructions (or pull out the
instruction label located in a holder on rear
shield of stove) . For piezo igniter location
see Figure 30.
Fasten the two latches located beneath the
firebox floor to the glass frame vee-flange.
Close both the latches securely.
Step 13. TEST ALL CONNECTIONS FOR
LEAKS (FACTORY AND FIELD).
WARNING
Never use an open flame to
check for leaks.
Step 15. BURNER ADJUSTMENTS
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally, most people prefer the warm glow
of a yellow to orange flame.
Appliances operated with air shutter openings
that are too large will exhibit flames that are
blue and transparent. These weak, blue and
transparent flames are termed anemic. If the
air shutter opening is too small sooting may
develop.
The flame should project 1" (25 mm) beyond
the hood at all three ports (Figure 32).
Replace logs if removed for pilot inspection.
To light the burner, rotate the gas valve control
knob counterclockwise to the “ON” position
then turn “ON” the ON/OFF rocker switch.

Burner Adjustment
Air Shutter Adjustment Guidelines:
If the burner flame appearance differs
greatly from what is shown on this Page
(see Figure 33), some adjustment from
standard for the air shutter gap may be
necessary (to compensate for variables in
the installation and fuel such as, BTU value
/ composition, gas pressure, specific gravity
of gas, altitude, etc.).
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

Initially, always position the air shutter to the
factory setting as shown in Figure 34 (adjust-
ment rod is located in the lower control area).
This can be done by moving the adjustment
rod up or down accordingly. Allow the burner
to operate for at least 15 minutes. Observe
the flame continuously. If it appears weak
or sooty as previously described, adjust the
air shutter to a more open position until the
desired flame appearance is achieved.
The adjustment rod and associated adjustable
airshutterispatentedtechnology.Flameadjust-
ments can be made quickly and accurately to
taste without the need of disassembling the
appliance and waiting for 30 minutes after
each adjustment.
Sooting is indicatedby black puffs developing
atthe tips of verylong orangeflames.Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
Sooting is caused by incomplete combus-
tion in the flames and lack of combustion air
entering the air shutter opening. To achieve
a warm yellow to orange flame that does not
soot, the shutter opening must be adjusted
between these two extremes.
No smoke or soot should be present. Repo-
sition the logs if flames impinge on any of
them. If the logs are properly positioned
and sooting conditions exist, the air shutter
opening on the main burner tube should be
adjusted. Normally, the more offsets in the
vent system, the greater the need for the air
shutter to be opened further.
Step 16. INSTALL STOVE TOP, TRIVET
AND ASH LIP
A. Place the cast iron top into position on the
stove top (See Figure 35). Place the trivet
into the recess on the cast iron top (See
Figure 35).
Figure 35
Figure 36
B. Locate the ash lip from packaging (Step 2).
Remove the 2 bolts from the tapped holes in
the ash lip. Align the ash lip below the firebox
as shown in Figure 36 (the tapped holes
in ash lip should align with corresponding
slots below firebox). Reinstall the 2 bolts
that were removed from the ash lip (finger
tight only. If a tool is used, be careful not to
overtighten).
