This manual contains information necessary for the safe installation and operation of your Kuma Arctic either in residential or mobile homes. While most
anyone can install their oil stove, it is recommended that the installation be done
by a qualified installer familiar with fuel oil stoves, preferably an NFI (National
Fireplace Institute) Certified expert. We recommend contacting local building or
fire officials in your area regarding restrictions and installation inspection requirements. Please read this entire manual before attempting installation or operation
of this appliance. Improper installation or operation of this oil stove can result in
bodily or property damage.

SECTION 1
Stove placement, air requirements, and clearances
Try to pick a location that will be somewhat central in the house or room in which you
wish to install the Arctic. Due consideration of the fuel tank location, ease of fuel line installation, and flue location is wise. You will want to read the fuel tank section to get a better idea of
where to locate the tank as well as the stove. The stove must be placed on hearth that is noncombustible, having a thickness of 3/8” or greater. A 36”x 36” hearth pad area is recommended. Once a location is established, the stove can be placed on the hearth and leveled. It is
absolutely imperative that your Arctic is level. There are adjustment bolts under each corner of
the pedestal base should these adjustments be necessary. Place a level on top of the pedestal
base both directions and adjust until level.
This unit has been tested to U.L. 307A and is approved for installation and use in manufactured homes. There are some special considerations when installing into a mobile or manufactured home. For model AR-10 (10” burner), the flue system must consist of a 4”,5” or 6”
diameter CLASS “A”, U.L. HT103 type insulated chimney, and a double-wall stove pipe connector. For models OC-7 and OC-8 (7” and 8” burner), a 4”,5” or 6” diameter Class “A” insulated chimney may also be used, or you may use an approved 4” diameter Class “L” (pellet
vent) chimney. Dura-Vent D.V.L. double-wall connector is required or 4” diameter Class “L”
vent may be used as a connector. As a general rule, smaller diameter flues are better for
draft and efficiency. For clarification see the chimney/connector table at the end of Section 2.
Single wall stove pipe connector may be used on residential installations (not for manufactured/
mobile homes). The manufactured home installation also requires an outside combustion air
source. For outside combustion air a 4” diameter or larger duct should be installed vertically
through the hearth and floor directly below the stove or horizontally through the wall connecting to the 4” opening at the stove back (flex ducting may be used). Make sure there is a rodent
screen with a maximum 1/4” x 1/4” opening placed in the duct to prevent rodents from accessing the stove. (Continued)

A storm or dryer type vent with a screen is adequate. For your convenience, an outside air kit
(part # 4OAVK) is available through your dealer.
If you are not installing this stove in a mobile home, and outside air is not desired, simply
remove the outside air cover at the stove back so ambient room air can enter. Please note that at
certain draft conditions (i.e. high winds) a significant amount of air may be needed to achieve a
proper burn. Consideration of open windows or an air source near the stove will probably be necessary depending on the “air-tightness” of your home. Again, outside air to your oil stove is a
good idea as it will make the combustion impervious to house pressure problems.
Optional Arctic Convection Shell Installation Instructions
(Part# ARCS)
functions: 1) Increased air flow. It provides a 3/4” jacket surrounding the sides and back of the
stove. The shell is vented at the bottom and top to promote convection air movement throughout
your home. 2) Decreased clearances. You will see in the clearance section of this manual that installation of this convection shell allows the Arctic to be installed considerably closer to
combustibles.
INSTALLATION:
1. Remove from the box and place the convection shell down over the stove from the top.
There are spacers welded inside that provide the correct rear and side spacing. Slide shell down
until it rests on the pedestal base then pull forward to ensure that the shell spacers are touching the
stove back.
2. Install the 4 self-drilling, self-tapping screws at the front of the side panels top and bottom with a high speed drill and a #2 Phillips driver bit. Screw all four screws until snug, do not
over tighten.
3. Installation complete. Stow the label under the stove bottom after all clearances have
been checked. The top hinges up allowing exposure of the firebox top for cooking or warming.
*Please note that these clearances are minimums. It is a good idea to exceed these clearances
unless space is limited. Common sense must prevail. The clearances are listed on a label that is
attached to the stove by a lanyard. After installation the label may be stowed under the unit. DO
NOT REMOVE LABEL.
An optional convection shell may be purchased from your dealer. This shell provides two

connector is required for mobile home installations.

The flue and flue connections
dedicated to the Arctic as the flue is, without a doubt, the most important component of the system. Good combustion is dependent upon the correct amount of air being supplied to the burner at all times, which is dependent
upon a correct negative flue pressure. Draft is caused by the gases inside the flue being hotter and lighter than
the air outside, thus the rising heated gases carry out the products of combustion. Since the flue “sucks” gases
up the flue, it is this suction that draws air into the pedestal area to feed the burn pot with the air needed for an
efficient, blue-flame burn. This will depend on the flue’s ability to provide a consistent negative pressure.
There is no substitute for a warm, efficient chimney/pipe system. If the flue gases cool too quickly, draft will
slow and combustion will not be as efficient. Do not skimp on the flue system. A good rule of thumb on chimney height is a minimum of 12’ from the stove to termination. Location of chimney and other factors may require more or less chimney height. In areas of high winds or draft inversions, a suitable wind-directional or vacuum cap may be needed.
An insulated chimney is a must in order to maintain the heat inside the chimney for proper flow of gases.
For model AR-10, use a class “A”,4”,5” or 6” diameter, all-fuel insulated chimney that has been tested to U.L.
HT103 when passing through combustibles. For models AR-7 and AR-8, a 4”, 5”, or 6” diameter Class “A” insulated chimney or an approved 4” diameter Class “L” (pellet vent) chimney is approved. As a general rule,
smaller diameter flues are better for draft and efficiency. The stove pipe connector may be single-wall black
pipe with tight fitting joints (mobile home connectors must be double-wall, see Section 1), and must be securely
fastened at all joints with 3 sheet metal screws. Fasten connector pipe to the flue collar on the stove and the ceiling box/wall thimble with screws as well. The Arctic may also be connected to a masonry chimney, but it will
need to be lined with a stainless steel liner and insulated as well. Use and install all piping according to the
manufacturers listed clearances.
Certain atmospheric conditions such as high winds will cause a change (increase) in the negative pressure inside the flue and thus inside the stove. To compensate for this, your AR-7 and AR-8 has an upper burn
ring that prevents over-draft conditions from affecting the burn. The AR-10 does not require a ring. In extremely high wind conditions, a tee in the stovepipe connector with a barometric damper may be required to help
compensate for these draft changes.
Do not connect this unit to a flue servicing another appliance. It is of utmost importance that the flue be
