Thank you . . .
THANK YOU FOR PURCHASING A HARMAN STOVE AND FOR READING
THIS OWNER’S MANUAL. It is our desire to provide as much data as needed to allow
you to install and operate your Harman Stove in the safest manner possible.
There are a number of excellent sources on wood heating which you might like to
purchase for your home library. These include “The Woodburning Encyclopedia” by Jay
W. Shelton; “Wood Heat” by John Vivian; and “The Complete Book of Heating With
Wood” by Larry Gay. Local fire departments provide an excellent source of counsel for the
novice woodburning customer.
If you have any questions regarding your Harman Stove which were not covered in
this manual, contact your local dealer or factory direct.

1.1 KEEP CHILDREN AWAY -­MAY CAUSE SERIOUS BURNS
CAUTION: ALL SURFACES OF STOVE ARE HOT. DO NOT TOUCH! KEEP CHILDREN AWAY. SERIOUS BURNS WILL RESULT IF TOUCHED. THIS IS A HEAT PRODUCING APPLIANCE. SERI­OUS BURNS MAY RESULT IF THE STOVE IS TOUCHED DUR­ING FIRING.
1.2 FUEL/FIRING WARNINGS
DANGER! FIRE HAZARD! DO NOT USE CHEMICALS OR FLU­IDS TO START OR “FRESHEN UP” A FIRE. SEVERE BODY BURNS OR A FIRE IN YOUR HOME COULD RESULT. DO NOT BURN GARBAGE, GASOLINE, THINNERS, DRAIN OR ENGINE OIL, KEROSENE, OR FUEL OIL, ETC. AN EXPLOSION, A HOUSE FIRE OR PERSONAL INJURY COULD RESULT. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE STOVE WHILE IN USE.
“NEVER” burn materials other than coal or split and dried wood logs. A chimney fire or heat exchanger fail­ure could result. This includes large amounts of corrugated boxes, wood shavings, paper scraps, dried Christmas trees, coke, garbage, tires, or other burnable products.
When and if the chimney pipes or connectors reach 500 degre e s fahrenheit (maximum temperature), the stove is being over-fired. We rec­ommend the purchase of a Harman Magnetic Te m p e r a t u re Gauge to monitor the stove and stack temper­atures relative to the amount of draft the customer permits the stove to operate.
It has been verified that creosote will ignite at 650 degrees fahrenheit. It is the owner’s responsibility to fol­low these recommendations.
This stove consumes air when it is burning. It is advisable that a win­dow in the vicinity be opened slight­ly while stove is burning if your house is tightly sealed and insulated. (Information contained in this man­ual is manufacturer’s recommenda­tions and if there is any difference between our recommendations and local code requirements, we suggest following local code requirements.)
1.3 Curing Paint
During the first few hours of burn­ing, a blue smoke will be observed rising from the painted surface of the stove. It is advisable to increase the amount of fresh air in the room during this breaking-in period. This may be achieved by opening doors, windows, etc. Don’t be alarmed, this is normal.
1.4 Mobile Home
Harman Stoves are not approved or recommended for mobile homes.
2.1 Heat Collector
Optional Heat Collector can be attached to the top of the stove to direct heat from the spiral chamber and stove top into a duct. CAU­TION: The duct rising off the heat collector should be kept ten inches away from combustible materials for the first fifteen feet from the stove. This includes floor joists, suspended ceilings, etc. Clearances may be reduced if fireproof material such as asbestos board or sheet metal with air space is used to protect com­bustibles. The heat collector slides on easily from the front of the unit. (See diagram on following page.)

4. Chimney
4.1 Types of Chimneys
The chimney is one of the most important, yet most neglected and misunderstood portion of any solid fuel burning installation. We do not recommend that the stove be con­nected to a chimney with other heating devices.
THE STOVE MUST BE CON­NECTED TO ITS OWN TILE­LINED FLUE. A MINIMUM FLUE SIZE OF 8" X 8" IS NECESSARY FOR PROPER OPERATION AND APPROVED FOR ALL FUELS.
UNDER NO CIRCUMSTA N C E S SHOULD A MANUAL FLUE DAMPER BE INSTALLED IN THE SMOKE PIPE BETWEEN STOVE AND CHIMNEY!
No damper, heat saver, or automat­ic vent damper device should be installed in or on the smoke pipe.
N O O T H E R A P P L I A N C E S SHOULD BE VENTED TO THIS FLUE!
CAUTION: THE CHIMNEY MUST BE A CLASS “A” CHIMNEY IN GOOD OPERATION CONDITION.
NOTE: THE USE OF ALUMINUM TYPE “B” GAS VENT FOR SOLID FUELS IS UNSAFE AND PROHIB­ITED BY THE NATIONAL FIRE PROTECTION ASSOCIAT I O N CODE.
There are three types of class “A” chimneys:
A. Masonry with tile liner to include brick or stone. It must be supported on grade level founda­tion.
B. Insulated Class “A” manufac­tured chimney, listed or certified by a national test agency.
C. Triple Wall Metal Class “A” chimney, listed or certified by a national test agency.
If your masonry chimney has not been used for some time, have it inspected by a qualified person (building inspector, fire department personnel, etc.). If a listed or certi­fied manufactured chimney is to be used, make certain it is installed in accordance with the manufacturer’s instructions and all local and state codes. See Figure No. 1 of Manufactured Chimney Installations and Figure No. 2 of masonry Chimney (note roof clearance) in accordance with NFPA 211.
4.2 Common Chimney Pro b l e m s
In order to have a proper operating solid fuel heating system, the chim­ney must be capable of providing the draft required.
The minimum required draft is .06 inches W.C. (water column). This must be measured using a draft gauge.
If the chimney cannot supply this constant draft, the unit will not operate properly.
In some installations, a barometric draft regulator may be used and properly adjusted to compensate for excessive draft.
IMPORTANT!
Whenever you measure the draft, the stove must be operating and suf­ficient time given for the chimney and stove to warm up. This should take a minimum of thirty minutes.
The draft reading is taken 18" up from the center of the stove flue outlet in the smoke pipe.
REASONS for insufficient draft readings:
A. Leaky Chimney - Air leaking in a r ound a loose fitting clean-out door, flue pipes not tight at the joints, improper plug openings or defective masonry.
B. Chimney Improper Height ­Chimney does not extend through the roof to a sufficient height to pro­mote sufficient draft or causes a down drafting condition to take place. (See Figure No. 3)
C. Obstructions in the chimney. Check prior to using by holding a mirror in chimney clean-out door. This will give a view of the chimney.
D. Trees or Other Topographical Barriers - Impeding the chimneys operation or causing a down draft condition to exist. This can also be caused by adjacent buildings or the roof of the same structure where the chimney is not high enough. (See Figure No. 3)
