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 of 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 termi-
nation 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', and the
maximum height shall be no more than 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.
•HORIZONTAL RUNS are not permitted anywhere in
the venting system.
• Venting liners CANNOT be less than 3” in diameter
or greater than 3” in diameter.
•Anyunused 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 adja-
cent walls is specified by building codes. A general
guide to follow is the Gas Vent Rule below.
VERY IMPORTANT
If the intake flex does not extend the full length
of the chimney and connect to the unit and the
termination cap - A METAL BLOCK OFF PLATE MUST
BE CONSTRUCTED AND INSTALLED ABOVE THE UNIT
BELOW THE END OF THE INTAKE DUCT (normally at
the damper area). See figure 2.
To avoid cross venting the insert, label the duct to
be used for the exhaust conduit at both the top and
bottom ends. This ensures that the exhaust duct will
be attached to the correct collar on the insert and on
the chimney termination kit.
CANADA NOTE: Both Intake and Exhaust ducts
must extend the full length of the chimney and be
connected to both the unit and the termination kit.

Venting through a Masonry Fireplace
1. Measure height of the chimney to fireplace opening.
Determine if both the intake and exhaust will be
extended to the top of the chimney. In Canada, both
liners must extend the full length of the chimney
and be connected to both the unit and the termina-
tion kit.
2. Cut the appropriate lengths of flex duct for both the
intake and exhaust. Label both ends of the Exhaust
duct.
3. Follow the manufacturer’s instructions to attach the
ends of the duct(s) to the chimney termination kit as
appropriate.
4. Drop the liners down the chimney from the top and
rest the termination kit atop the chimney.
5. Seal the chimney termination kit to the top of the
chimney flue with high temperature sealant.
6. Secure the appropriate direct vent cap to the
termination kit.
7. Inside the fireplace, fully extend the duct and trim
any excess so that the ends hang approximately 15”
from the floor of the fireplace.
8. If the Intake duct is not attached to the chimney
termination kit:
A. Install a minimum 6 foot length flex duct for the
up the flue.
B. A METAL block-off plate must be constructed and
installed in the damper area to completely seal off
the flue from the room. Cut holes in the plate for
both the Intake and Exhaust liners.
C. A direct vent cap is required to allow fresh air into
the chimney flue and ultimately into the intake duct
to the insert.
9. Compress the ducts so that they are hanging above
the height of the fireplace opening and are out of
the way.
10. Position the insert without surround panels half-
way inside the fireplace and attach duct you labelled
Exhaust to the Exhaust collar on the insert. Both
Intake and Exhaust collars are labelled.
11. Secure the ducts to the collars with sheet metal
screws or hose clamps. No silicone or sealant is
required.
12. Once the gas line is installed, carefully push the
unit inside the fireplace.
See page 13 for gas line gas line connection.
See page 19 for surround panel installation. Warning: Failure to position the parts in accordance with this
diagram or failure to use only parts specifically approved with this
appliance may result in property damage or personal injury.

Prefabricated Fireplace Installation
A factory-built fireplace will require modification prior
to installation of the insert.
Modification
1. Remove any fuel grate and other components if
attached. On most models, the firegrate is attached
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.
IMPORTANT:
BEFORE STARTING THIS INSTALLATION, MAKE
SURE THAT A GAS LINE CAN BE INSTALLED
OR IS INSTALLED TO THE FIREBOX. THIS
SHOULD ONLY BE DONE BY A QUALIFIED OR
LICENSED PLUMBER OR GAS FITTER.

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-combus-
tibles.
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 combustible.
Always maintain the proper clearances to allow for
the proper flow of ventilation air around the insert.
Fireplace Clearances
Measure clearances from the center and finished floor
of the fireplace opening.
A = 40” (1016 mm) to a Side Wall, (any combustible
surface that extends more than 1 1/2” from the
fireplace face)
B = 22” (559mm) to Side Trim that extends 1 1/2” or
less from the fireplace face. If the side trim extends
more than 1 1/2” from the fireplace opening then Side
Wall clearance applies.
C= 36” (867mm) to Top Trim that extends 1 1/2” or less
from the fireplace face.
D = 38” (915mm) to a Mantel that extends no more
than 14 1/2” from the fireplace face.
NOTE: MANTEL AND TOP TRIM CLEARANCES ARE
NOT AFFECTED BY THE USE OF THE 2” RISER BAR.
Hearth Requirements
Flush Hearth: requires a non-combustible hearth in front
of the fireplace that extends a minimum of 18” (457mm)
and is a minimum of 32” (813mm) wide.
Raised Hearth: A raised hearth that is at least 6” high
requires a non-combustible hearth in front of the fire-
place that extends a minimum of 12” (305mm) from the
fireplace face and is a minimum of 32” (813mm) wide.
Hearth must be minimum 6” high to
extend only 12” in front
12”
NOTE: USE OF THE 2” RISER BAR DOES NOT EFFECT THE
HEARTH REQUIREMENTS LISTED ABOVE.

THE SPACEPROVIDED.
16. Reassemble the insert, apply gas to the system and
check for gas leaks including all insert lines before
and after the valve.
NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.
IMPORTANT
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
Pressure 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.

Secure all joints tightly using appropriate tools and
sealing compounds (for propane units, be sure to use
compounds that are propane resistant). Turn on gas
supply and test for gas leaks using a soapy water
solution. Never use an open flame to check for leaks.
Leak Test:
·Mix a 50-50 solution of water and dish soap.
·Light appliance - See lighting instructions on page
23 of this manual or on the rating plate.
·Brush or spray all joints and connections with the
soapy water solution.
·If bubbles appear at any connection or seam or a gas
odor is detected, immediately turn gas control knob
to the OFF position.
Tighten or reconnect the leaking joint and retest for
any gas leaks.
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.
IN / E for inlet or supply pressure (the amount of gas
coming to the valve.)
OUT / A for manifold pressure (the amount of gas that
is coming out of the valve to the burner.)
The appliance must be isolated from the gas supply
line by closing its individual manual gas shut-off valve
(gas cock) during any pressure testing of the gas supply
piping system that is equal to or exceeds pressures
of 1/2 psig (3.5kPa).

Symptoms of incorrect gas pressure include:
Insufficient gas pressure:
• Small pilot flame which can result in insufficient
millivolts.
• Little variation in flame picture between HI and LO
settings.
• Insufficient gas to support more than one appliance
causing nuisance outages or gas surges.
Excessive gas pressure:
• Permanent damage to valve causing complete
appliance shut down.
• Too large a pilot flame resulting in over heating of
the power generator causing shut down.
• Sooting due to impingement and/or incorrect fuel to
air mix.
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.
In the U.S.
THE DERATING KIT MUST BE INSTALLED BY AN AUTHO-
RIZED SERVICE TECHNICIAN IN ACCORDANCE WITH THE
MANUFACTURER’S INSTRUCTIONS AND ALL CODES AND
REQUIREMENTS OF THE AUTHORITY HAVING JURISDIC-
TION. THE INFORMATION STICKER MUST BE FILLED OUT

Flame Adjustment / Air Shutter
THE KATAHDIN GAS INSERT IS SHIPPED FROM THE
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
appearance is a matter of preference, however most
consumers enjoy the warm, yellowish flame.
Closing the Air Shutter - Insufficient combustion
air will result in very long yellow flames that can
promote soot. Sooting produces black deposits on the
logs, on the inside walls of the appliance, and poten-
tially on the exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.
Opening the air shutter - will generate a flame that
is blue and transparent, or an “anemic” flame. This
flame is generally more efficient, but not very attrac-
tive.
Jøtul recommends the following settings for the
Katahdin gas insert:
Propane: 1/4” open
Natural Gas: 1/4” open
REMEMBER: Run the insert for a minimum of 15 to
20 minutes for an accurate representation of the flame
appearance. This should be done before and between
any air shutter adjustments.
To adjust the air shutter
1. Remove the burner tube and using a phillips head
screwdriver loosen the screw at the air shutter and
adjust accordingly.
2. Be sure to retighten the screw that holds the air
shutter setting.
3. Reassemble the insert including glass assembly.
Allow insert to burn 30 minutes on the HIGH setting,
observing the flame continuously.
4. If the flame appears weak, slow, or sooty, repeat the
process described above until the flame is as desired.
Installing the Log Set
NOTE: Install the optional Antique Brick Panels before
installing the Log Set.
The Katahdin is equipped with a three piece log set
packaged in bubble wrap inside the firebox. The log set
must be removed from the packaging and arranged in
the unit prior to start up of the gas insert. Protect your
hands by wearing gloves to prevent skin irritation from
the ceramic fibers.
1. Unwrap each log and set on floor near unit.
2. Lift out andiron.
3. Place rear log over the rear log pins in the rear of the
firebox. The rear log should be installed with the
tapered end of the log on the right.

Blower Operation
The GI 450 DV Katahdin is equipped with a 125 cfm
heat-activated blower. A ten foot power cord is in-
stalled in the rear of the valve compartment under the
firebox.
Open the Lower Grill and fully unwrap the power
cord. The cord can exit either the right or left side of the
insert. Be sure to pull all slack out of the power cord to
prevent contact with the bottom of the firebox.
The is equipped with a three-prong (grounding)
plug for protection against shock hazard and should be
plugged directly into a properly grounded three-prong
receptacle. DO NOT CUT OR REMOVE THE GROUNDING
PRONG FROM THE PLUG.
The blower must be electrically grounded in
accordance 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.
Figure 18. Blower Controls
Figure 17. Completed log set assembly.
4. Place the front log on the single log pin so that the
left end of the log rests on the log support and the
andiron holder- directly above the air shutter.
5. Place the cross-over log on the two remaining pins-
top right to the rear log, bottom left on the front log.
See fig. 17.
6. Install the embers: the insert is shipped with a
package of ember stones. Spread them evenly across
the burner tube screen. It is best to equally space
these embers for optimum flame appearance. NOTE:
YOU DO NOT NEED TO USE ALL OF THE EMBER
STONES.
7. Replace the andiron set, center in the firebox over the
andiron support.
THE CERAMIC FIBER LOGS AND EMBER STONES CAN
IRRITATE YOUR SKIN. IF THIS HAPPENS, GENTLY WASH
HANDS WITH WARM, SOAPY WATER.

Wall Thermostat
When installing a wall mounted thermostat to the
Katahdin, it must be a 750 millivolt DC two-wire circuit
thermostat. The thermostat should be placed in the
same room as the heater, typically 5’ off the floor. Avoid
drafty areas or any area that may affect the accuracy of
the thermostat.
The thermostat should be connected to the
Katahdin using a minimum of 16 gauge wire with a
maximum length of 35 feet of wire.
Connect the two thermostat wire leads to the two
lower terminals on the terminal block located to the
right of the ON/OFF/TSTAT switch. Do not overtighten
the connections. IT IS NOT NECESSARY TO DISCONNECT
ANY OTHER WIRES. See Figure 20.
For the thermostat to function, the ON/OFF/T-STAT
switch must be in the T-STAT position, and the pilot
light must be running, as it is the power source for the
thermostat.
At the thermostat, the two wires should be con-
nected to the two connections screws on the thermo-
stat base plate per the manufacturer’s instructions.

Surround Panel Installation
Complete the venting and gas line installation before
installation of the surround and riser bar.
RISER BAR: The 2” riser bar is used in conjunction with
the standard surround, and is only needed in the event
that the fireplace opening is between 27 1/2” and 29
1/2” high. The riser bar can be used in any installation
if desired. See fig. 22.
Start with the insert slightly pulled out of the fireplace.
1. If the riser bar is to be used the insert must be lifted
2” off the floor of the fireplace to allow for the riser
bar to fill the space below the bottom grill assembly.
Exception: in raise fireplace installations the riser
bar may extend toward the hearth. See fig. 22.
2. This can be done through the use of the four leveling
legs that are included with the unit. One leveling leg
is threaded through the floor in each corner of the
fireplace.
3. Any other non-combustible material can be used to
lift the unit the necessary 2” for the riser bar.
NOTE: DUE TO THE WEIGHT OF THE SURROUND AND
RISER BAR IT MAY BE NECESSARY TO UTILIZE THE
STABILIZER BAR THAT IS SHIPPED WITH THE UNIT.
THIS STABILIZER ATTACHES TO THE OUTSIDE OF THE
FIREBOX AND WILL BRACE THE UNIT AGAINST THE
FIREPLACE LINTEL PREVENTING THE UNIT FROM
LEANING FORWARD. See figs. 22 and 22A.
4. Lay the four surround panels on the floor backside
up. Using two bolts and washers attach the right
and left upper sections (breastplates) together. See
fig. 23.
5. Attach the left and right leg sections to the breast-
plate assembly using a bolt and washer on each side.
See fig. 24.
6. Four mounting tabs are attached to the back of the
surround panels at the factory. Be sure all four tabs
are in place and secure. See fig. 25.
7. Stand the assembled surround up and gently lift to
the unit. Align the mounting holes on the sides of
the insert with the mounting tabs on the surround.
See fig. 25.

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 appli-
ance 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.
Reminder: Be sure to inspect the gas line and
blower cord to make sure they are not crushed
when the unit is in its final location.

Fireplace Operation
1. The GI 450 DV Katahdin gas insert 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. RE-
PLACEMENT 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 DOOR. 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.
