Vent Installation Procedure
The GI 450 DV Katahdin gas insert must be vented
through dual 3” flexible gas aluminum liners listed for
use with gas appliances.
This co-linear installation includes a pair of 3” flex
ducts that run from the insert up through the existing
chimney.
One duct is attached to the exhaust port on the
back of the unit and will carry the exhaust gases to
the outside of the house. This exhaust liner must run
the full length of the chimney and be directly con-
nected to the chimney termination cap. See figure 2.
The other 3” liner will be attached to the intake
port on the back of the unit and will provide fresh air
for combustion to the unit. This liner must extend a
minimum ominimum o
minimum ominimum o
minimum of 6’f 6’
f 6’f 6’
f 6’ off the back of the unit and extend
through the damper area of the fireplace and into the
tile liner of the chimney. This liner can also extend the
full length of the chimney and connect to the termina-
tion cap. See figures 2 and 4.
Vent Guidelines
• All vent components must be installed in accordance
with the terms of their listing and manufacturer’s
instructions.
• The minimum height of termination cap from the
top of the unit shall be no less than 10'10'
10'10'
10', and the
maximum height shall be no more than 35'35'
35'35'
35'. See
figures 2 and 4.
• Steep roofs, nearby trees, or predominantly windy
conditions can promote weak draft or occasional
downdrafts. In such cases, increasing the height of
the vent or installation of high wind termination
caps may alleviate the condition.

• Venting liners CANNOT be less than 3” in diameter or
greater than 3” in diameter.
• Any unused flue or masonry enclosure can be used as
a passageway for venting PROVIDED the flue is
relined using 3” Listed Flexible Gas Liner.
• The remaining space around the liner in a masonry
or zero-clearance flue CANNOT be used to vent any
other appliance.
• Listed Flexible Gas Liners may not be exposed to any
living space.
• Installation of any components not manufactured or
approved by Jøtul or failure to meet all clearance
requirements will void all warranties and could result in
property damage, bodily injury, or loss of life.
• Never modify any venting component, or use any
damaged venting product.
• THE GAS APPLIANCE AND VENT SYSTEM MUST BE
VENTED DIRECTLY TO THE OUTSIDE OF THE BUILD-
ING, AND NEVER ATTACHED TO A CHIMNEY SERVING
A SOLID FUEL OR GAS BURNING APPLIANCE.
• The minimum vent height above the roof or adjacent
walls is specified by building codes. A general guide
to follow is the Gas Vent Rule below.

to the unit with brackets which can be cut or pried off.
2. Remove the damper assembly. This includes the
damper blade, handle and any linkage. Two 3” liners
must be able to pass through the damper area.
3. Remove any firescreen or door assembly. This is
usually accomplished with removal of a support rod
on the inside of the fireplace frame.
4. Remove the metal ashlip, if appropriate, to allow the
insert to sit flat within the fireplace. Be sure to
reinstall any screws removed.

Clearance Requirements
The following clearances and hearth specifications are
the minimum requirements for installing the GI 450
Katahdin Insert into a solid fuel-burning fireplace. See
figs. 5 through 8.
A combustible surface is anything that can burn (i.e.
sheet rock, wallpaper, wood, fabrics etc.). These surfaces
are not limited to those that are visible and also include
materials that are behind non-combustibles.
If you are not sure of the combustible nature of a
material, consult your local fire officials. Remember,
“Fire Resistant”materials are considered combustible;
they are difficult to ignite, but will burn. Also,“fire-
rated” sheet rock is considered cc

Always maintain the proper clearances to allow for
the proper flow of ventilation air around the insert.

Correct gas pressure is essential for efficient and safe
operation of the Katahdin gas insert. It is important
that the correct gas pressure be established at the time
of the installation. For more details, see the Gas Pres-
sure section of this manual on page 14.
ALWAYS REFER TO THE LIGHTING INSTRUCTIONS ON THE
BACK COVER OF THIS MANUAL WHEN LIGHTING YOUR
KATAHDIN.
Gas Supply Connection
The gas supply line connection is made to the valve on
the left side of the unit facing the front. The gas supply
line should be a minimum of 3/8" in diameter, or the
appropriate size to provide sufficient gas pressure to the
valve regardless of the input setting.
See fig. 11 and 12.
For your convience the GI 450 DV Katahdin is
shipped with a short piece of 3/8” iron and a 24” length
of flexible gas line. Jotul recommends the use of the
flexible gas line for ease of installation and service.
However, for those areas where flexible gas lines are not
permitted use of the 3/8”iron is recommended. See fig.
12.
The use of Flexible Gas Appliance Connectors is
acceptable in many areas in the U.S., however, Canadian
methods vary depending on local code.
ALL INSTALLATIONS MUST COMPLY WITH LOCAL
CODE OR IN THE ABSENCE OF LOCAL CODE, MUST
COMPLY WITH THE MOST RECENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR
CAN-B149.
All codes require:a gas shut-off valve (gas cock) .union,
to be installed in the supply line, and in the same room as
the appliance. This allows for the disconnection of the
insert for servicing and maintenance. See fig. 12.
T-handle gas cocks are required in
Massachusetts in compliance with
code 248CMR.

Gas Pressures
Correct gas pressure is essential for efficient and safe
operation of the Katahdin gas insert. It is important that
the correct pressure is established at the time of the
installation.
Proper gas pressure provides a consistent flow of
gas to the appliance and is instrumental in checking for
gas leaks.The gas control valve on the insert is equipped
with pressure test points for gauge connections. The
gauge connections are located on the front of the valve
under the On/Off/Pilot knob. See fig. 13.

High Altitude Adjustment
When installing GI 450 Katahdin insert at high altitude
(above 2000'), it is necessary to compensate for the
thinner air (less volume of air per cubic foot). Higher
altitudes affect the atmospheric pressure and heat
value of gaseous fuels.The lower oxygen content in the
air and the lower gas viscosity require the use of a
different orifice to achieve efficient, clean combustion
at the burner tube.

FACTORY EQUIPPED FOR USE WITH NATURAL GAS.
WHEN USING PROPANE, IT WILL BE NECESSARY TO
ADJUST THE AIR SHUTTER ON THE BURNER TUBE TO
ACHIEVE THE PROPER GAS TO AIR MIX. See fig. 15.
WARNING:
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
The air shutter adjustment can also help achieve
the desired flame appearance. Generally, flame appear-
ance is a matter of preference, however most consum-
ers enjoy the warm, yellowish flame.

The blower must be electrically grounded in accor-
dance with local codes or, in the absence of local codes,
with the current NFPA 70- National Electrical Code or
CSA C22.1-Canadian Code.
The blower is controlled by a heat activated switch
(snapstat) that will function only if the blower control
switch is in the AUTO setting. Once the firebox heats
after the burner has been operating for a short time, the
blower will start on either the HI or LOW speed. In AUTO
mode, the blower will continue to operate after the
burner is turned off, until the snapstat cools. See fig. 18.
If blower operation is not desired, place the control
switch in the OFF position to bypass the snapstat
function.
NOTE:
ALWAYS UNPLUG THE BLOWER WHEN
SERVICING THE APPLIANCE.

3. BURNER ADJUSTMENT: The burner is equipped with a
variable gas control valve. This valve provides easy
adjustment of the flame height appearance and heat
output. To adjust the flame between the HI and LO
setting, rotate the HI/LO knob, located in the center
of the valve face. Flame height will adjust approxi-
mately 1.0” to 1.5” between the HI and LO settings.
NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG
PLACEMENT IF ANY SOOT OR SMOKE IS APPARENT. IF
SOOT OR SMOKE PERSIST, THE AIR SHUTTER MAY
REQUIRE ADJUSTMENT.
CAUTION:
DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE BY
POSITIONING THE GAS VALVE IN ANY OTHER POSITION
OTHER THAN THE FULL “ON”POSITION.
Checking the System
1. PURGING THE GAS LINE: When lighting the appliance
for the first time it will take a few moments to clear
the gas line of air. Once this purge is complete, the
appliance will operate as described in the lighting
instructions located on the insert’s rating plate and
back cover of this manual. All subsequent lightings
of the insert will not require such purging of the gas
line.
2. PILOT FLAME: The pilot flame should be steady, not
lifting or floating. The flame should be blue in color
around the pilot hood,,
,,
, with traces of yellow toward
the outer edges. It is imperative that the pilot flame
engulf the top 3/8” of the thermopile (power genera-
tor) and the top 1/8”of the quick drop out thermo-
couple. The pilot flame should project out of the
pilot hood 1” at all three ports. See Figure 28.
8. Slide the surround down into the mounting holes.
Be sure all four mounting tabs engage securely with
the adjacent bracket holes. See fig. 26.
9. Secure the two sections of the riser bar together
with a washer and bolt and slide the assembled
riser bar under the bottom grill assembly on the
unit. Attach the Riser Bar to each leg panel with a
bolt and washer as shown in fig. 25.
Note: the riser bar is not used for support of the
insert- if more space is needed for the riser bar, raise
the unit using the front levelling legs. See figure 27.
10. Gently and slowly push the unit and surround back
into the fireplace. This is best done by pushing the
front outside edges of the glass frame. RR

Fireplace Operation
1. This appliance is equipped with an On/Off/T-stat
rocker switch to control burner functions. Use the T-
stat position for use with an optional wall-mounted
thermostat. Separate switches are provided for the
multifunction forced air blower kit.
2. When lit for the first time, the Katahdin will emit an
odor for several hours. This odor is the burn-off by-
products of external paints and lubricants used in
the manufacturing process. Open a nearby window
to provide fresh air and alleviate this temporary
condition.
3. Condensation may occur on the glass upon each
lighting of the appliance. This “fog” will disappear as
the appliance temperature increases.
4. Keep the controls and the area under the appliance
free of debris; vacuum this area frequently. Always
keep the appliance area clear and free from combus-
tible materials, gasoline and other flammable liquids.
ALWAYS be sure the insert is cold and NO hot embers
or sparks are present before using a vacuum cleaner.
5. Remember, this appliance has a continuous burning
pilot flame. Exercise caution when using products
with combustible vapors.
6. CAUTION: DO NOT OPERATE THIS APPLIANCE WITH
THE GLASS REMOVED, CRACKED OR BROKEN.
REPLACEMENT OF THE GLASS SHOULD BE DONE BY A
LICENSED OR QUALIFIED SERVICE PERSON. USE ONLY
REPLACEMENT GLASS PROVIDED BY YOUR AUTHO-
RIZED JØTUL DEALER. NEVER USE ANY SUBSTITUTE
MATERIALS.
WARNING:
OBSERVE CAUTION NEAR THE GLASS. THE GLASS PANEL
MAY SHATTER UNEXPECTEDLY IF STRUCK WITH AN
OBJECT. ALWAYS HANDLE THE GLASS PANEL WITH CARE.
7. Clean the glass only when necessary. Wipe surface
with a clean, dampened, soft cloth. Follow with a dry,
soft towel as desired. Take care not to scratch the
glass surface.
WARNING:
DO NOT USE ABRASIVE CLEANERS ON THE GLASS. NEVER
CLEAN THE GLASS WHEN IT IS HOT.
Maintenance
The Katahdin gas insert and its venting system should
be inspected before use and at least annually by a
qualified service technician.
IMPORTANT:
ALWAYS TURN OFF THE GAS SUPPLY TO THE INSERT AND
UNPLUG THE FORCED AIR BLOWER BEFORE ANY
SERVICE WORK IS PERFORMED ON THE INSERT.
General cleaning: The firebox should be vacuumed out
annually to remove any surface build up. Be sure to
vacuum or wipe off the pilot assembly and burner
orifice and burner tube. Also, when vacuuming the
log set, be sure to handle it carefully as it is very
fragile.
Gasket inspection: It is important that the glass gasket
be inspected at least annually. Examine the rope
gasket for signs of deterioration and make sure the
gasket has a positive seal. This is important to
prevent combustion gases from escaping into the
room. Replace the gasket if necessary, refer to the
replacement parts list on page 23.
To remove the glass panel or glass gasket:
1. Open the bottom grill assembly.
2. Release the glass clips on either side of the bottom of
the firebox.
3. Swing the bottom of the glass frame out and lift
slightly.
4. Remove the glass panel by lifting the glass frame over
the brackets at the upper grill assembly. NOTE: IT IS
NOT NECESSARY TO REMOVE THE UPPER GRILL
ASSEMBLY.
5. Lay the assembly on a flat surface and lift the metal
tabs that secure the glass panel to the frame.
6. Install the new glass panel and gasket in the glass
frame and secure with metal tabs. Do not over
tighten tabs as this could break the glass.
ALWAYS USE JØTUL AUTHORIZED PARTS. NEVER
SUBSTITUTE ANY OTHER PARTS.
