Check Building Codes
When installing, operating and maintaining your
Jøtul C 350 Fireplace Insert, follow the guidelines
presented in these instructions, and make them
available to anyone using or servicing the stove.
Your city, town, county or province may require a
building permit to install a solid fuel burning appli-
ance.
In the U.S., the National Fire Protection Associa-
tion’s Code, NFPA 211, Standards for Chimneys,
Fireplaces, Vents and Solid Fuel Burning Appliances,
or similar regulations, may apply to the installation
of a solid fuel burning appliance in your area. For

IN YOUR AREA. WHEN NOT ADDRESSED IN
THIS MANUAL, OR BY LOCAL CODE AUTHORI-
TIES, INSTALLATION SPECIFICATIONS AND
REQUIREMENTS DEFER TO NFPA 211 OR CSA
B 365
• DO NOT CONNECT THIS FIREPLACE TO ANY
AIR DISTRIBUTION DUCT OR SYSTEM .
• EXTREMELY HOT WHILE IN OPERATION!
KEEP CHILDREN, CLOTHING AND FURNITURE
AWAY. CONTACT WILL CAUSE SKIN BURNS.
• NEVER OPERATE THE FIREPLACE WITH A
CRACKED OR BROKEN GLASS PANEL.
• Install smoke detectors in the living areas
and bedrooms of your home. Test them
regularly and install new batteries twice
annually. When installed in the same room
as the stove, a smoke detector should be
located as far from the stove as possible to
prevent it from sounding when adding fuel
to the fire.
• Avoid creating a low pressure condition in
the room where the stove is operating. Be
aware that operation of an exhaust fan or
clothes dryer can create a low pressure area
and consequently promote flow reversal
through the stove and chimney system. The
chimney and building, however, always work
together as a system - provision of outside
air, directly or indirectly to an atmospheri-
cally vented appliance will not guarantee
proper chimney performance. Consult your
local Jøtul authorized dealer regarding spe-
cific installation/performance issues.

U.S. Requirement:
The insert is connected to a listed stainless steel
flexible connector that extends into the first chim-
ney flue tile liner. A sealed block-off plate must be
installed at the damper area of the existing fireplace.
See fig. 7.
For internal chimneys, (no sides of the chimney
exposed to the outside below the roofline,) a posi-
tive connection to the first flue tile is acceptable
provided the tile is no larger than 8” x 12”.
For external chimneys (one or more sides are ex-
posed to the outside below the roof line, including
garages), a positive connection to the first flue tile is
acceptable provided the tile is no larger than
8” x 8”.
A 6”, 7”, or 8” stainless steel liner, extending the
full height of the chimney, is required for all instal-
lations where the flue tile is greater than 8” x 12” for
internal chimneys, or 9” x 8” for external chimneys.
Canada Requirement:
The insert must be installed with a continuous chim-
ney liner of 6” (152 mm) diameter extending from
the fireplace insert to the top of the chimney. The
chimney liner must conform to the Class 3 require-
ments of CAN/ULC-S635, Standard for Lining Systems
for Existing Masonry or Factory-Built Chimneys and
Vents, or CAN/ULC-S640, Standard for Lining Sys-
tems for New Masonry Chimneys.
See fig. 8.
Do not use aluminum or galvanized steel pipe for
chimney connection components - these materials
are not suitable for use with solid fuel.
Installation
1. Remove the existing damper and linkage compo-
nents from the fireplace. Alternatively, you can
wire the damper plate to lock it in the open posi-
tion. Thoroughly clean the firebox and smokeshelf
area with a wire brush.
2. If the fireplace has been modified to accommo-
date installation, use anchors or masonry nails to
attach the metal Fireplace Conversion Notice Plate

Chimney Connection
This insert must be connected to a code-approved
masonry chimney or listed factory-built fireplace
chimney with a direct (positive) flue connector into
the first chimney liner section. The chimney size
should not be less than, nor more than, three times
greater than the cross-sectional area of the flue col-
lar.
The optional Jøtul Draw-Down Adaptor Kit
156073 is available to ease connection of the chim-
ney liner with the flue collar.
A positive connection must be made between the
fireplace insert and the chimney by one of the fol-
lowing approved methods.
Installing the Fireplace Insert
Leveling Bolts
The leveling bolts are used to compensate for ir-
regular hearth surfaces. More importantly, they also
provide a method of adjustment f0r the correct
vertical (plumb) and horizontal (level) alignment of
the surround assembly with the fireplace face and
hearth.
If you are installing the Bottom Trim section
with the Surround assembly, you must use the level-
ing bolts to level the front-to-back pitch of the fire-
box or the Surround assembly will be out of plumb.
See fig. 9 below.
Install the leveling bolts all the way into either
the Riser Bar or Firebox.

Install the Riser Bar
1. If appropriate to your installation (see pg. 8), posi-
tion the riser bar centered within the fireplace as
shown in fig. 10. The forward ends of the Riser Bar
should be aligned within 1/2 inch of the fireplace
face.
Install the Firebox
1. With the help of an assistant, slide the Firebox
into the fireplace cavity. If using a Riser Bar, the
Firebox must be engaged with the Riser by means
of the Locking Pin included in the hardware bag.
Pull the Left Blower forward out of the way to ac-
cess the Locking Pin hole in the firebox floor. See
figs. 10 and 11. When the front edge to the firebox
is aligned with the front edge of the Riser, the
Locking Pin hole will be aligned with the slot in
the top of the Riser Bar crossmember. Insert the
Locking Pin and pull the firebox out slightly proud
of the fireplace face to facilitate attaching the sur-
round panels. Relocate the blower.
Figure 12. AC power receptacle lead routing.

Surround Assembly
All fasteners have already been installed in the ap-
propriate locations at the factory. You will need to
remove them, attach the parts together as described
below and reinstall the fasteners at those locations.
1. Layout the parts. Place the castings face down on
a protective surface such as carpeting, blankets or
a sheet of cardboard.
2. Attach the Breastplates to each other.
Use a 10 mm socket or wrench with two M6 x 10
hex head flange bolts. Adjust the set screw to
obtain parallel alignment of the two plates.
3. Attach the Leg plates. The Legs must be oriented
with the Hang Tabs on the inside edges as shown
in
fig. 12. Use the two remaining M6 x 12 hex head
flange bolts to attach the Legs to the Breastplate
assembly.
4. If the Riser Bar is used, attach the two Bottom
Surround Trim panels together with the single
M6 x 10 hex bolt. Attach the Trim Mounting Brack-
et to the back of the Bottom Trim assembly using
the other two M6 x 10 bolts. Be sure to orient the
bracket as shown in fig. 14.
Tools Required:
• 10 mm socket or wrench
Tighten just snug enough to allow for final adjust-
ment when the Surround assembly is attached to
the firebox.
Bend the perforated mounting plate down 90°
as shown in Fig 14. Insert and center the bracket
plate sandwiched between the firebox and the
Riser Bar.
5. If appropriate, attach the Extended Surround
Panel to the firebox. With the painted side facing
out, engage the hooked tabs on panel with the
slots in the backside of the Surround Brackets on
the firebox. Extend the blower power cord out
beyond the surround panel.
6. Attach the Assembly to the Firebox. Lift the entire
assembly upright and position it in front of the
insert firebox. The four Hang Tabs on the surround
legs must engage with the adjacent cutouts in the
two brackets on either side of the firebox opening.
The surround will easily engage with these brack-
ets if the firebox is slightly proud of the fireplace
opening.
Hang the surround assembly on the firebox and
push the entire unit into position so that the sur-
round is flush against the fireplace face.

Operation
Read the following section carefully before building
a fire in your fireplace insert..
Fuel
This stove is designed to burn natural wood ONLY.
Wood that has been air-dried for a period of 6 to 14
months will provide the cleanest most efficient heat.
Frequent use of green or inadequately seasoned
wood is conducive to creosote accumulation and
generally poor performance.
DO NOT BURN...
•Coal •Treated or painted wood
•Garbage •Chemical Chimney cleaners
•Cardboard •Colored paper
•Solvents •Any synthetic fuel or logs
The burning of any of these materials can result in
the release of toxic fumes. NEVER USE GASOLINE,
GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHAR-
COAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START
OR “FRESHEN-UP” THE FIRE. Always keep such liq-
uids away from the heater at all times.
Air Control Settings
A single lever regulates the Primary Air flow that
controls the intensity of the fire and consequent heat
output and burn time. This lever is located within the
slot on the upper right front of the fireplace insert.
When first starting or reviving the fire, the
control lever should be set at the far right position
to allow the maximum amount of air into the stove.
See fig.15. After the fire is well-established, the lever
should be set at position to moderate incoming air to
maintain the desired long term heat output and/or
burn time.
In general, the more air made available to the
fuel will result in the hottest fire intensity and the
fastest fuel consumption. Alternatively, the less air
made available to the firebox will result in low heat
output and slow fuel consumption.
Use the following guide for best performance.
Burn Rate Air Control Setting Blower Speed
Low 1/8” Open Low / On at 30 min.

Starting and Maintaining a Fire
Burn only solid wood directly on the bottom plate of
the stove. Do not elevate the fire in any way.
1. Set the Air Control Lever in the full open position. 2.
Crumple several sheets of newspaper directly on
the bottom plate..
2. Place several pieces of small dry kindling (approx.
1” in diameter) on top of the newspaper, with two
to three small logs (approx. 2” to 3” in diameter)
on top.
3. Light the fire and close the door. Gradually build
the fire by adding larger and larger logs as the fire
develops a bed of coals.
4. When you have added the final logs, adjust the Air
Control Lever to provide the desired fire intensity.
Experiment with a variety of air control set-
tings to determine the best one for your individual
circumstances. Remember that fuel characteristics,
chimney system condition, building design, and
weather conditions all affect the performance of
your fireplace insert. In time, you will discover how
these elements combine and how you can work with
them to achieve satisfactory performance.
Adding Fuel to the Fire
When reloading the stove while a bed of hot embers
still exists, follow this reloading procedure:
• Always wear stove gloves when tending to the
fire.
• Push the Air Control Lever to the full open position
(far right).
• Always wait a few seconds before opening the
door. This allows the renewed air circulation to
clear unburned gases from the firebox.
• Use a stove tool or poker to distribute the hot
embers equally around the firebox.
• Load the fuel, usually with smaller logs first.
Keep logs behind the andirons. See fig. 16.
• Close the doors and secure the latch.
• Wait 5 – 10 minutes for the fire to re-establish be-
fore adjusting the Air Control Lever for the desired
heat output. If a thick bed of live coals is present,
you may be able to add fuel and immediately set
the air control without waiting for the fire to be
re-established.
Creosote Formation
This appliance is designed to burn wood cleanly
and efficiently when operated as described in this
manual. However, when wood is burned slowly and
at low temperatures, tar and other organic vapors
are produced which condense on the relatively cooler
chimney flue surfaces to form creosote. Failure to
keep the chimney system free of creosote build up
could result in a chimney fire.
The creosote that accumulates in the chimney
is highly flammable and is the fuel of chimney fires.
To prevent chimney fires, it is important to have
the chimney flue and connector pipe inspected at
least twice monthly during the heating season and
cleaned whenever accumulation of 1/4” or more is
evident. A qualified chimney sweep or other autho-
rized service person can provide this service.
Figure 16.
Fuel load area - keep logs behind the andirons.
Break-in Period
The cast iron parts of your fireplace insert require a
break-in process to allow them to gradually adjust to
thermal expansion and contraction. This is accom-
plished by building a series of three or four fires, each
somewhat hotter than the last. Allow the fireplace
insert to cool completely before building the next
fire.
Limit the first fire to just kindling and a couple of
1 -2 inch logs and add progressively more and larger
logs to subsequent fires, keeping the Air Control set
to the fully open position.
It is normal for a new fireplace insert to emit
odor and possibly smoke during the first few fires.
This is characteristic of the burn-off of residues from
the manufacturing process and the curing of painted
surfaces. Open a window near the fireplace insert to
provide plenty of fresh air to the room during this
“seasoning” period.
NEVER OVERFIRE THE STOVE. IF ANY PART OF
THE STOVE OR CHIMNEY GLOWS, YOU ARE
OVERFIRING. A HOUSE FIRE OR SERIOUS DAMAGE
TO THE STOVE OR CHIMNEY COULD RESULT. IF
THIS CONDITION OCCURS, IMMEDIATELY CLOSE
THE AIR CONTROL.
Keep logs behind
Andirons

Blower Operation
Access the blower control panel by lifting the cast
iron lower grille up off the insert.
The dual blowers will enhance heat circulation
around the firebox and out into the room. In the
Automatic setting, the blowers are controlled by a
heat activated switch (snapstat) that will only func-
tion when the speed control is ON. After the fire has
been burning for a time, the snapstat will react to
the heat and activate the blowers. Conversely, the
blower will continue to operate until the snapstat
cools as the fire wanes. The blowers will then shut
off automatically.
The Manual setting overides the snapstat func-
tionality allowing blower operation regardless of
temperatures.
For best performance, do not turn the switch on
until after the fire is well-established.
If the blower is not needed, place the blower
control switch in the OFF position.

INSERT.
It is also important to remember that chimney
size, temperature and height all affect draft which in
turn affects the formation of creosote. An exterior
chimney, whether masonry or prefabricated steel,
will be exposed to cold outside temperatures, and
consequently, will be more prone to creosote accu-
mulation than an interior flue.
A chimney flue located within the home interior
will benefit from the insulating characteristics of the
building itself. Consequently, the flue system will be
less conducive to condensation of unburned gases
and minimal creosote accumulation will result..
As a general rule, try to avoid burning the insert
at the lowest air control settings. Although a low
setting will prolong burn time, it may also result in
incomplete combustion. In reducing the fire intensi-
ty, draft is weakened and the chimney flue cools. This,
together with the increase in unburned gases, leads
to rapid creosote accumulation.

Maintenance
Glass Care
Cleaning
Occasionally it will be necessary to clean the car-
bon deposits and fly ash off of the glass. If deposits
are allowed to remain on the glass for an extended
period of time, the glass may become etched and
cloudy.
Creosote deposits should burn off during the next
hot fire.
1. The glass must be COMPLETELY COOL.
2. Only use a cleaner that is specifically designed for
this purpose. DO NOT USE ABRASIVE CLEANING
AGENTS. The use of abrasives will damage the
glass, leaving a frosted surface. Crumpled newspa-
per is an especially good cleaning material.
3. Rinse and dry glass completely before lighting a
fire.
Glass Replacement
Always operate the doors slowly and cautiously to
avoid cracking or breaking the glass. Never use the
door to push wood into the firebox. If the glass
becomes cracked or broken follow the replacement
procedure below.
Ash Removal
Always wear stove gloves when handling ashes.
Ash removal will be required periodically depend-
ing on how frequently the stove is used. Use a steel
ash shovel and metal container with a tight-fitting
lid. NEVER USE A PAPER OR PLASTIC BAG AS AN ASH
RECEPTACLE.
The container of ashes should be placed on a
noncombustible floor or on the ground, well away
from all combustible materials, pending final dis-
posal. If the ashes are disposed of by burial in soil
or otherwise dispersed, they should be kept in the
closed container until all coals and cinders have
thoroughly cooled.
IMPORTANT:
NEVER OPERATE THE STOVE WITH A
CRACKED OR BROKEN GLASS PANEL.
Replace glass only with part # 156069
specifically designed for the Jøtul C 350
Winterport Fireplace insert. Do not use
substitutes. Replacement glass can be
ordered from your Jøtul dealer.
1. Remove the door from the stove and place on a
flat surface.
2. First loosen and then carefully remove all of the
glass clips from the inside of the door. See fig. 19.
3. Remove all pieces of the glass panel and gasket-
ing.
4. Remove all remaining debris from the glass area
using a wire brush.
5. Apply a small bead of gasket/stove cement and
the new gasket. Do not overlap the ends of the
gasket rope.
6. Orient the glass with the IR Coating label facing
out. Hold the glass at an angle to see the word
“COATED” located at the lower edge. This side
should face out when placed in the door. Center
the new glass panel over the gasket and loosely
reinstall the glass clips. Tighten the clips, alternat-
ing at opposite corners. Avoid applying uneven
pressure on the glass..
7. It may be necessary to retighten the glass clips
after the stove has burned and the gasketing has
seated.

General Maintenance
Regular maintenance will assure proper perfor-
mance and prolong the life of your fireplace insert..
The following procedures do not take long and are
generally inexpensive. When done consistently, they
will help increase the life of your fireplace insert
and assure satisfactory performance.
• Thoroughly clean the insert. Enamel surfaces
should be cleaned with a moist cloth and pol-
ished dry..
• Empty firebox of all soot and ashes. Never use a
household vacuum cleaner to remove ashes. Only
a shop vac with a metal container is acceptable
and only when you are certain the ashes are cold.
• Inspect the firebox using a utility light inside and
out for cracks or leaks. Replace all cracked bricks
and repair leaks with furnace cement.
Removing the Insert for Cleaning
U.S. Direct-connection Only:
1. Disconnect the blower power cord from its out-
let.
2. Open the firebox door and pull the insert out
enough to disengage the surround panel assem-
blies by lifting up off of the brackets.
3. Remove the three screws that attach the flue
connector to the flue collar, and disengage the it
from the insert.
5. Pull the firebox and cabinet forward as a unit.
The flue connector, liner, and chimney can now
be inspected and cleaned.
6. See the Installation section of this manual for
reassembly procedures.
Canada Installations (Full Reline):
The chimney can be swept directly into a bucket
placed under the flue outlet, with removal of the
two cast iron baffle plates.
1. Push up on the Left Baffle to disengage its locat-
ing boss from the Secondary Air Tube.
2. Slide the Secondary Air Tube to one side to disen-
gage it from the opposite side Air Channel and
remove it from the firebox.
3. Lift the Right Baffle up and forward off of the
rear and side support shelves.
4. Repeat with the Left Baffle.
5. Re-assemble in the reverse order, being sure to
engage the nub on the Left Baffle with the hole
in the Secondary Air Tube.
Gaskets
Check door and glass gaskets for seal integrity.
The gaskets should be soft enough to be somewhat
resilient to the touch. Over time, gaskets will com-
press and harden. Replace worn-out or hardened
gaskets with the appropriate size material available
from your local Authorized Jøtul Dealer.
To check the seal of the front doors, close and latch
the doors on a dollar bill and slowly try to pull the
dollar bill free. The seal is too loose if the bill can be
easily removed. Adjust the door latch and test again.
Gasket Replacement
See the chart below for replacement gasket specifi-
cations. See also fig. 20 for locations.
1. Remove the old gasket material with a pliers and
thoroughly clean the channel with a wire brush.
2. Lay out the new gasket around the channel to de-
termine length. Trim the gasket to leave 1” excess.
2. Apply a small bead of furnace cement in the chan-
nel.
3. Lightly press the new gasket into the channel, be-
ing careful to avoid compressing or stretching it.
Trim the gasket further as necessary to allow the
tail end to slightly overlap the other end.
4. Wait ten minutes to allow the cement to set and
then close and latch the doors. Reopen the doors
and, using a damp cloth, wipe away any excess
cement that may be squeezed out from under the
gasket.
