Welcome to the Kuma family.

Kuma is a modified version of the Greek word Kauma that means

“a great heat”.

We would like to take the time to say thank you for

purchasing a Kuma stove. If this is your first Kuma stove, you

have joined a long list of family members, some since 1981. We

relationship with each and every one of our customers. Our

mission is to provide you with a quality product that will last a

lifetime. If you ever have a problem with your stove, we will do

what is needed to get it resolved and keep you warm.

You may have noticed a portion of the Bible enclosed in your

owner’s packet. It is a small gift for you. Our faith in Jesus Christ

is very important to us and we have that faith because there is hope

in heaven. That hope comes from the message of truth that is found

in this New Testament.

Thank you for allowing us the opportunity to warm your

house. May God bless you and we anticipate that you will enjoy

the use of your new Kuma wood stove.

Sincerely,

The Freeman Family

Section 1– Safety Precautions

Install and use in accordance with the manufacturers installation and operation instructions

contained in this manual only.

1. If this stove is not properly installed, a house fire can occur. For your protection, follow the

installation instructions provided. We recommend contacting local building or fire officials

regarding restrictions and installation inspection requirements in your area. We also recommend

that your Kuma model Wood Classic wood stove be installed by a properly trained and

licensed installer, preferably a NFI (National Fireplace Institute) expert.

2. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVICING ANOTHER

APPLIANCE.

3. Do not use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids

to start or “freshen up” a fire in this heater. Keep all such liquids well away from the heater while

it is in use.

4. Do not burn garbage.

5. DO NOT OVERFIRE. If any part of the stove or chimney glows, the stove is in an overfire

condition. If this happens, shut the air control off immediately.

6. WARNING: DO NOT INSTALL IN A SLEEPING ROOM

7. CAUTION: The structural integrity of the floor, wall and ceiling/roof must be maintained.

8. DO NOT USE SINGLE WALL PIPE FOR ANY CHIMNEY APPLICATION, EXTERIOR

OR THROUGH THE WALL OR CEILING. Single wall pipe may only be used as a

connection between the stove and an approved masonry or stainless steel chimney. Single wall

pipe may not be used as a connector in mobile homes.

9. When installing into an existing masonry or metal chimney, examine the chimney system

carefully. If you have any questions, seek professional advice. We recommend having existing

chimneys cleaned and inspected by a qualified professional prior to the installation of your new

stove.

10. NOTE ALL MINIMUM CLEARANCE REQUIREMENTS TO COMBUSTIBLES.

Installation must comply with minimum clearances as listed in this manual. (see section 6)

11. Do not operate this stove with the door in an open position.

12. Do not operate this stove with the ash pan open.

13. This stove must be connected to a minimum 6” diameter listed chimney that complies with U.L.

type 103HT factory built chimney or a code approved masonry chimney. If the masonry chimney

does not meet code, a U.L. 1777 approved liner must be installed.

14. When connecting single wall or double wall connector pipe to the stove and chimney, use 3

screws per pipe joint including 3 screws securing the pipe to the stove. Depending on the type of

double wall pipe you are using, it may also be necessary to fasten it at the chimney. Simpson

Duravent’s DVL double wall uses a snap lock connector and does not need screws.

15. When connecting this stove to a masonry chimney, make sure you observe all applicable

clearances including walls, ceilings and other combustible material. A masonry chimney must be

minimum 6” diameter and constructed with a liner according to NFPA code 211. If you have any

questions about the condition or the code compliance of your masonry chimney, please speak

with a qualified professional.

16. WHEN PENETRATING A COMBUSTIBLE WALL TO CONNECT TO AN OUTSIDE

MASONRY CHIMNEY YOU MUST BE CERTAIN THAT THE WALL PASS THROUGH

IS A SAFE AND LISTED METHOD. Please refer to NFPA code 211 for details about listed

wall pass through methods. To obtain a copy of the NFPA code 211, you may visit their website

at www.nfpa.org or call them toll free at 1(800)344-3555. Your local building department may

also have information regarding NFPA code 211.

Section 2– Mobile home installation

INSTALL AND USE IN ACCORDANCE WITH THE MANUFACTURER’S INSTALLATION

AND OPERATING INSTRUCTIONS ONLY. WHILE MOST ANYONE WITH BASIC

CARPENTRY SKILLS CAN SUCCESSFULLY AND SAFELY INSTALL THEIR KUMA WOOD

STOVE, IT IS HIGHLY RECOMMENDED THAT IT IS INSTALLED BY A QUALIFIED

PROFESSIONAL WHO IS PROPERLY TRAINED AND LICENSED–PREFERABLY AN NFI

CERTIFIED (NATIONAL FIREPLACE INSTITUE) EXPERT.

CAUTION: The structural integrity of the mobile home floor, walls and ceiling/roof must be maintained.

Use additional bracing if required. Never cut a load bearing wall or engineered truss. Use elbows if

necessary to offset the pipe.

CAUTION: NEVER INSTALL A STOVE IN A SLEEPING ROOM.

STEP 1:Make sure you have the proper tools, materials, and stove components.

Tools:

1. Reciprocating Saw

2. Assorted Screwdrivers

3. Measuring Tape

4. Pencil

5. Plumb Line

6. Electric or Cordless Drill with assorted drill and driver bits

7. Tin Shears

8. Utility Knife

9. Pliers

10. Hammer

11. Assorted Wrenches

Materials:

1. Caulking to seal roof flashing and storm collar. High temperature silicone is recommended.

2. Assorted heavy duty nails and screws.

3. Short pieces of 2x4 or 2x6. Two pieces minimum 24” long.

4. Copper wire (8 gauge) for grounding. Grounding “clamp” “terminal” or “lug” for attaching

ground wire at stove and mobile home frame.

Stove Components: (each component has installation instrucions included see sec. 8 for a complete

list of accessories)

1. Stove body (K-WC)

2. Pedestal or leg kit (KA-WCPED, KA-WLEGSTEEL, etc.)

3. Door Kit (DOOR1CASTC, DOOR1GOLDC, etc.)

4. Outside air kit (KA-OUTSIDEAIR)

5. Optional Blower (KA-BLOWER1)

Determining the stove location:

When choosing a stove location there are a few things that should be considered.

1. Try to choose a location that is centrally located in the house.

2. Try to choose a location that will be easy to access from your wood storage area.

3. Survey the roof area above and around the location of the chimney exit. Be sure there are no

dormers, roof valleys or any other roof irregularities that could cause difficulty when trying to set

and seal the roof flashing.

4. If possible, survey the attic area above and around the location of the chimney. Be sure there are

no major obstructions such as plumbing, heating ducts, electrical wires, phone cables, etc. Also

check the crawl space below and around the stove location for the same obstructions.

STEP 2: Installing the chimney.

IMPORTANT: These instructions are a very basic guideline for the steps to installing your chimney.

For complete instructions, refer to the installation manual that came with your chimney. Chimney

installation instructions are usually located in the box with the chimney cap or chimney support

components. If you have any questions about the installation of your chimney, please contact the

dealer where you purchased your stove.

CAUTION: Inspect all chimney components for damage. Do not use any damaged chimney

components.

1. Familiarize yourself with the clearances of the stove, for the configuration in which you have

chosen to install, i.e. corner installation or straight wall installation (see section 6). Notice the

clearances listed for the chimney, this will help you determine the location of the hole in the

ceiling.

2. Once you’ve determined the hole location for the chimney, use a drywall saw or reciprocating saw

to cut the ceiling to the desired hole size. BE SURE TO CHECK FOR OBSTRUCTIONS

BEFORE CUTTING THE HOLE, REFER TO PIPE INSTALLATION INSTRUCTIONS

FOR HOLE SIZE.

3. Use a plumb to transfer the ceiling hole center to the underside of the roof sheeting in the attic.

Once you’ve marked the hole center on the roof sheeting, drill a hole from the inside or poke a

screw or nail through the sheeting so you can find that location once you’re on the roof.

4. Always be careful when using a ladder and working on a roof. Have someone hold the

ladder for you while you are climbing up and down. Use a positioning belt or harness and

safety rope to secure yourself on the roof. Locate the hole or screw/nail on the roof that you

poked through from the attic. Lay the roof flashing down and center over the hole, screw or nail.

Using a pencil, trace the inside of the flashing cone onto the roof. Remove the flashing and use a

reciprocating saw to cut out the hole. Cut the hole out about 1” larger than the mark all the

way around.

5. Use the two pieces of 2x4 or 2x6 to brace across the trusses in the attic. Position the bracing in a

way that you will be able to attach the chimney support with the proper clearance to the bracing

(see chimney installation instructions for proper clearances). Attach the chimney support to the

bracing using screws or nails.

6. Using a flat pry bar, gently lift the shingles off the roof from the middle of the hole up. Slide the

flashing up under the shingles on the top half of the hole and let the flashing sit on top of the

shingles on the bottom half of the hole. Use silicone or roof tar to seal underneath the flashing and

use screws or nails to fasten the flashing to the roof. Be sure to apply a small amount of sealer to

each screw head.

7. Slide the first section of chimney through the flashing and into the chimney support. Chimney

supports vary from one brand of pipe to another. Be sure that the first section of pipe is well

secured into the chimney support, again, paying close attention to the chimney manufacturers

installation instructions.

8. Continue to fasten chimney sections above the first one until the correct height is reached (see pipe

installation instructions and section 6 of this manual).

9. Install the chimney cap.

10. Install the storm collar above the flashing and use high temp silicone to seal.

11. If necessary, install a roof brace or guy wires to steady the chimney. Bracing is usually required if

the chimney extends more that five feet above the roof.

STEP 3: Installing the Hearth and Outside air.

CAUTION: The Kuma Wood Classic Stove can be configured as a Freestanding Stove, supported by

either Legs or a Pedestal Base. Each configuration has different floor protection requirements. See the

section below that pertains to your particular installation.

Minimum Requirements:

The minimum floor protection requirements for the Kuma Wood Classic model are as follows:

Floor protection must consist of a continuous non-combustible material and extend a minimum of 16 in

front of the loading door and 6" to both sides and the rear of the stove body.

Additional requirements for material thickness and thermal resistance are described below.

1. Wood Classic with Pedestal Base: Installed as a freestanding stove on a pedestal base the Kuma

Wood Classic requires Ember Protection only. Ember Protection can take the recommended form

of a manufactured Type-1 floor protector listed to UL-1618, or a non-combustible continuous

material with a MINIMUM thickness of 3/8”.

2. Wood Classic with Legs: Installed as a freestanding stove on legs the Kuma Wood Classic

requires both continuous ember protection and Thermal Protection with a minimum R-Value of

0.60. Thermal Protection can take the recommended form of a manufactured Type-2 floor

protector listed to UL-1618 with a tested R-Value higher than R = 0.60. Alternately a site built or

existing hearth can be used provided they meet the minimum size and thermal resistance

requirements. Never install this stove with legs on an existing hearth unless you can determine it

provides a minimum thermal resistance of R = 0.60.

CAUTION: The Kuma Wood Classic Stove can be equipped with an optional Soapstone top Accessory.

When this Model is installed with a Soapstone top, the requirements for hearth protection change. An R-

Value of 0.60 must be added to the requirements listed above. See the instructions and safety label that

are included with the Soapstone top Accessory.

Outside Air – Outside air is required in all manufactured home installations.

1. Kuma stoves does not particularly require that outside air be directly connected to this

stove, However, some state or local building codes may mandate outside air. If your state or

local building code requires an outside air supply use part# KA-OUTSIDEAIR. If you are unable

to supply a direct connection to the stove or if you need additional ventilation due to room air

starvation, we suggest the following:

a. Provide a passive air supply to the home. The air vent should be a minimum of 4” in

diameter.

b. The air supply must be provided to the same room that the stove is installed in.

c. The air supply should utilize a barometric damper so that air is only supplied to the room

if the house pressure becomes negative.

Visit www.woodheat.org for more information on the use of outside air.

2. When building a hearth pad on site, be sure to leave an area open for the installation of the

outside air vent. Once the hearth is positioned according to the minimum clearances, locate and

mark out the hole for the 4” outside are vent. On a pedestal model stove, this hole may be

anywhere under the stove base. On a leg model stove, try and locate the hole to line up with the

hole in the bottom of the stove. On a pre-manufactured hearth, use a hole saw or circular saw to

cut through just the backing board then use a hammer and firmly hit the tile or stone on the top

side. If the backing board was cut to the correct depth, the tile or stone will break out very clean.

Also using a hole saw or circular saw cut the hole through the home floor into the crawl space. Be

sure to line this hole up with the one in the hearth.

3. If you are installing your outside air vent through the wall, use a 4” hole saw or reciprocating saw

to cut the hole through the wall. BE SURE TO CHECK FOR OBSTRUCTIONS IN THE

WALL.

STEP 4: Setting the stove and connecting to the chimney

1. Attach the legs or pedestal to the stove following the instructions provided in the box with them.

Once the legs or pedestal is attached, set the stove gently on the hearth using cardboard to protect

the hearth. (If using cast or plated legs you must use legs spacer part# KA-WCLSK)

2. Position the stove on the hearth according to the clearances shown on the diagrams in section 6.

Be sure that the stove is at least minimum clearance from all combustible walls and materials. If

possible it is advisable to set the stove 1-2 inches further away from the combustibles than

required.

3. USING DOUBLE WALL PIPE ONLY, (single wall is not approved for a mobile home) connect

the stove to the chimney. If necessary, use elbows to offset the pipe so that the stove can remain at

the correct clearance and still connect to the chimney. Secure each pipe joint with three screws,

using the screws provided with the pipe.

4. Drill a small hole through the hearth and route the 8 gauge copper wire into the crawl space. Use

a grounding “connector” or “lug” to attach the ground wire to the stove and to the frame of the

mobile home.

5. When required by local code, you will need to fasten the stove to the floor of the mobile home. To

fasten a leg model, simply mark the location of the hole in the bottom of the legs, drill holes and

bolt into the bottom of the leg from the crawl space. To fasten a pedestal model, holes will need

to be drilled in the pedestal base. Once the holes are drilled in the base, mark the location on the

floor and use bolts and nuts or lag screws to fasten.

Your stove is now ready for use. If your stove installation required a permit and requires inspection by the

local building department please do not forget to call for an inspection. It is important that your permit and

inspection be finalized, as some insurance companies will require the stove to be inspected. It is also a

great idea to give your insurance a call and let them know that you have installed a wood stove.

PLEASE REFER TO SECTION 4-Wood Burning Operation Instructions before lighting your first fire.
