INTRODUCTION
Thesevented gasheaters are sealed combus-
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.

the elevations indicated:
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 & 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 local building department
who will be able to give you the necessary
installation requirements for your area (Is
a building permit required?, Rooms where
installation may not be allowed?, etc.).

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:
WARNING: If logs are not installed accord-
ing to the directions shown here, flame
impingement and improper combustion
couldoccur and resultinsoot and/or exces-
sive production of carbon monoxide (CO),
a colorless, odorless, toxic gas.
These appliances are 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.Loosensetscrewatinlet pressure tap on upper
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 gas control
valve down in the pilot position until pilot will
light (see Figure 19). DO NOT 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.
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).

Test For Gas Leaks
A. Mix a 50% dish soap, 50% water solu-
tion.
B. Light the appliance (refer to the lighting
instructions provided in the Homeowner's
Care and Operation Instructions).
C. Brush all joints and connections with the
soapy water solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the “OFF” posi-
tion and close the gas shut-off valve. Either
tighten or refasten the leaking connection
and retest as described above.
D.When the gas lines are tested and leak free,
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,
turn off unit, allow it to cool, then clean out
the ports.
Turn on gas supply and test for gas leaks
using a soapy water solution. Never use an

with the indentation on front left log as shown
in Figure 26.
8. Install the front right twig onto the cor-
responding pin on the right front log. Align
the twig with the indentation on the front right
log as shown in Figure 27.
9. Place the glowing embers on the burner
as shown in Figures 28 & 29.
One package of ember material has been
included with this log set You will not need
to use the entire bag.
IMPORTANT: The quantity and placement of the
ember material can affect stove performance
therefore it is very important that it be placed
as shown in Figures 28 & 29.
a.Unpackage and divide the fine ember material
(mineral wool) into dime-sized fluffy pieces.
b. Distribute the pieces over the top of the
front burner ports avoiding covering the slots
(see Figure 29) and filling the area in front of
the forward logs.

(Reverse instructions on Step 4)
Retrieve the front glass enclosure panel.
Visually inspect the gasket on the backside
of the frame. Gasket surface must be clean,
free of irregularities and seated firmly.
Withthe stove top off, position the glass front
enclosure panel into the front opening with
the gasket facing the relief door (reference
Figure 8 & 9). Let the bottom of the door
frame gently slide down, then hook the top
flange of the glass frame over the top of the
firebox frame.
Fasten the two latches located beneath the
firebox floor to the glass frame vee-flange.
Close both the latches securely.

APPEARANCE.
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.
Air Shutter Adjustment Guidelines:
Ifthe 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 / composi-
tion, 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.
SIT Millivolt Appliance Checkout
The pilot flame should be steady, not lifting
or floating. Flame should be blue in color
with traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should
be engulfed in the pilot flame. 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.

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
airshutteris patented technology.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 indicated by blackpuffs developing
atthe tipsof very long orange flames. 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.
