Practical Tips For Building a Fire

Safe Wood-Burning Practices
Is your wood dry?
Take the moisture meter test.
Wet wood can create excessive smoke which is wasted fuel. A moisture Wet wood can create excessive smoke which is wasted fuel. A moisture
meter that allows you to test the moisture level in the wood is provided.
Properly dried wood should have a reading of 20% or less. Dry
wood creates hotter fires. Hotter fires save wood - ultimately saving you
time, money, and help to protect the environment. Burn Wisely.
Keep all flammable household items - drapes, furniture, books, etc. - far away from the
appliance.
Start fires only with newspaper, dry kindling and all natural organic fire starters. Never
start a fire with gasoline, kerosene, or charcoal starter.
Do not burn wet or green (unseasoned) logs. These will cause creosote buildup that could
lead to a chimney fire.
Do not use logs made from wax and sawdust. If you use manufactured logs, choose those
Do not use logs made from wax and sawdust. If you use manufactured logs, choose those
made from 100% compressed sawdust.
Build hot fires. A smoldering fire is not a safe or efficient fire.
Keep the doors of your wood-burning furnace closed unless loading or stoking the live fire.
Harmful chemicals, like carbon monoxide, can be released into your home.
Regularly remove ashes from your DAKA wood-burning furnace into a metal container
Regularly remove ashes from your DAKA wood-burning furnace into a metal container
with a cover. Store the container of ashes outdoors on a cement or brick slab (not a wood
deck or near wood).
Keep a fire extinguisher handy.

Clean and Efficient
Heating Checklist
Refer to your owner’s manual for installation guidelines and operating instructions.
Start a small fire with dry kindling then add a few pieces of wood at a time.
Give the fire plenty of air - fully open the air controls until the fire is roaring and stack
temperature is in the burn range.
Burn the fire to heat the chimney or flue before adding more wood.
Keep space between the firewood as you add more to the fire. Large tightly stacked loads of
Keep space between the firewood as you add more to the fire. Large tightly stacked loads of
wood may not be able to burn efficiently.
Check for local burn bans and avoid wood furnace use while in effect.
Avoid burning garbage, treated lumber, or saltwater driftwood. Burning these items can
damage your furnace and cause serious health issues.
Check your chimney regularly and have your stove and chimney professionally inspected and
serviced yearly.
A smoldering fire or smoke from the chimney are both signs that a fire needs more air or
A smoldering fire or smoke from the chimney are both signs that a fire needs more air or
your wood is too moist. There is a difference between smoke and water vapor. A good hot
fire may produce some water vapor but very little smoke.

SUPPLEMENTARY / CENTRAL
WOODBURNING FURNACE MODEL 832
DAKA Corporation • 955 Industrial St NE • Pine City, Minnesota • 55063
Phone [phone] • Fax [phone] • www.dakacorp.com
INSTALLATION AND OPERATION INSTRUCTION MANUAL
NOTE: These models have been tested and listed in accordance with
Underwriters Laboratories standard UL 391-2010-March 2010 and Sept.
2010 for Solid Fuel Central and Supplementary Furnaces by Warnock
Hersey International, Inc. ICBO Report No. TL116; NER Qa219.
PRINCIPLE OF OPERATION:
These furnace models are designed for conventional upflow residential central forced air heating systems,
to be installed in either of the following ways:
1. Supplementary "Add-on" Furnace Application (See Figure 1)
As a supplementary furnace, these models are connected in parallel to a conventional
primary furnace system, using present ductwork to distribute wood-heated air throughout
the home. As long as the heat produced by the supplementary furnace keeps the living
area temperature above the setting on the primary furnace wall thermostat, the primary
furnace should not burn any gas, oil, or use any electricity beyond that required to run the
primary distribution blower. Should the wood fire fail to provide sufficient heat, however,
the primary furnace will begin operating as usual.
2. Central Furnace Application (See Figure 2)
This furnace also may be used as a freestanding central furnace, with its own plenums
and ductwork. The large multi-speed blower provided with this furnace is sufficient to
provide air distribution for most homes. As wood burning requires periodic attention,
use of this unit as a central furnace is somewhat inconvenient and requires a second
heating system (electric baseboard, vented gas room heaters, etc.) to act as a backup.
CAUTIONARY NOTES:
1. This furnace is designed for use only in conventional upflow systems, and must deliver heated
air to a supply (warm air) plenum, never to ductwork. The warm air supply from this furnace
must never be connected to the cold-air return inlet of a central primary furnace, as a
possibility exists of components of the central furnace overheating and causing the central
furnace to operate other than as intended. Do not use as freestanding radiant heater.

daka 832 furnace manual_3-18-13 Page 2 of 14
September 26, 2012, Revised March 18, 2013
2. Installation of this unit must be performed by a qualified installer familiar with solid-fuel systems.
3. This furnace must be connected to a minimum 6" listed Type HT (high temperature) appliance-
type chimney, or a code-complying tile-lined masonry chimney. Connection to a chimney
flue serving another appliance is prohibited.
4. A barometric regulator/damper must be used in the chimney connector (smoke pipe leading to
chimney flue) and must be set to maintain no more than .06" water column updraft
(DAKA barometric regulator #283 with adjustable settings available at extra cost through your DAKA
dealer or online @ www.dakacorp.com / Energy Division or by calling Toll-free 1-800-884-3252).
5. Installation of this furnace in mobile homes or garages is prohibited.
6. This furnace must be installed on a non-combustible floor surface such as solid concrete or
3/8” non-combustible floor protector board. This surface must extend at least 16” in front and
8” to both sides of the furnace and also extend at least 2” out from the sides of the chimney
connector. See Fig. 3 for ductwork clearances and Fig. 4 for wall clearances.
Clearance to combustible surfaces are as follows:
To Side Wall
12"
Flue to Back Wall
18"
To Back Wall
28”
Flue to Side Wall
21”
To Front Wall
48”
Top of plenum to ceiling
6”
If you have any questions regarding venting your furnace, request a copy of the
National Fire Protection Association’s (NFPA) Publication 211 [Standard for Chimneys,
Fireplaces, Vents & Solid Fuel-based Appliances].
National Fire Protection Association
1 Battery March Park, Quincy MA 02169-7471,
1-617-770-3000 or online at www.nfpa.org.
7. Check local building and mechanical codes prior to installation to insure conformance with all
requirements; review home insurance policy for coverage.
8. Chimney Requirements:
1) Minimum 6” inside diameter
2) “Type HT” (High Temperature)-listed appliance-type chimney or a code-complying tile-lined
masonry chimney.
3) Chimney must extend 3’ above roofline and be at least 2’ higher than any point of roof
within 10’.
DO NOT install more than two 90° degree elbows in the flue pipe to help maintain proper draft.
This furnace requires its own independent chimney. DO NOT connect to a chimney flue
serving another appliance.
All horizontal runs must have a minimum upward rise of ¼” per foot.
The chimney connector (smoke pipe leading to chimney flue) must be of minimum 24-ga. pipe
with each section joined with three sheet metal screws. All fissures should be sealed with
furnace cement. Do not use galvanized pipe as the coating could melt and cause toxic fumes.
A stack thermometer is recommended. Stack temperatures can be checked with a simple
surface-mounted or probe-type thermometer. It is recommended to maintain normal operating
range of 300-600 ° F. Temperatures lower than 300° F indicate insufficient draft or inadequate
combustion air and may result in creosote formation in chimney flue.
The maximum draft setting is a maximum of .06” W.C. (measured in water column). Use of a
gauge is highly recommended. Follow gauge manufacturer’s instructions. Gauges to

daka 832 furnace manual_3-18-13 Page 3 of 14
September 26, 2012, Revised March 18, 2013
measure chimney draft are readily available at furnace shops and are economical to purchase
or rent. If a draft gauge is not available, with the draft regulator fully installed and a good fire
burning, adjust the counterbalance weight closer to the gate for as low a draft setting as
possible, without the fire dying or getting smoke-back with the stove door slightly open. To
obtain higher heat levels, move the weight away from the gate to increase the setting.
9. It is designed to operate with a maximum warm air duct pressure of 0.2” water column and a
maximum warm air duct temperature of 250° degrees F. The warm air supply duct system
must be constructed of materials with a minimum temperature rating of 250° degrees F.
Plenums installed to the furnace must be constructed of metal. Do not use flexible pipe.
IMPORTANT: WHETHER INSTALLED AS A SUPPLEMENTARY/ADD-ON OR CENTRAL
FURNACE, INSTALLATION OF A COLD AIR RETURN LINE IS MANDATORY.
10. When any supplementary furnace is connected in parallel to an existing primary central
furnace, a back-draft damper must be installed in the plenum of the primary furnace below
the warm air inlet from the supplementary furnace to prevent the primary furnace from
operating in an unintended manner; see Fig. 1 for an illustration of the position of this
damper.
DANGER - RISK OF FIRE OR EXPLOSION. DO NOT BURN GARBAGE, GASOLINE, DRAIN OIL
OR OTHER FLAMMABLE LIQUIDS.
WARNING - RISK OF FIRE. DO NOT OPERATE WITH FLUE DRAFT EXCEEDING .06" WATER
COLUMN. DO NOT OPERATE WITH FUEL LOADING OR ASH REMOVAL DOORS OPEN, DO
NOT STORE FUEL OR OTHER COMBUSTIBLE MATERIAL WITHIN MARKED INSTALLATION
CLEARANCES. INSPECT AND CLEAN FLUES AND CHIMNEY REGULARLY.
CAUTION - HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.
MAXIMUM DRAFT MARKED ON NAMEPLATE.
Disposal of Ashes
Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes
should be placed on a non-combustible floor or on the ground, well away from all combustible
materials, pending final disposal. If the ashes are disposed of by burial in the soil or otherwise locally
dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.
Creosote - Formation and Need for Removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-
burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote
makes an extremely hot fire.
The chimney connector and chimney should be inspected at least twice monthly during the heating
season to determine if a creosote buildup has occurred. If creosote has accumulated, it should be
removed to reduce the risk of a chimney fire.

plates on blower junction boxes.
V. CONNECTIONS TO DUCTWORK
A. FOR USE AS A SUPPLEMENTARY "ADD-ON" FURNACE (SEE FIG. 1)
NOTE: A back draft damper must be installed in the warm-air supply plenum of the primary
furnace below the point where the warm air ductwork connection from the DAKA furnace enters
the plenum. Actual design and installation procedure for such a back-draft damper is left to the
installer, due to the large number of plenum configurations involved. See Fig. 1 for illustration of
placement.
1. Using 10" round starter collar as template, mark and cut out 2 10" round holes in the side of the
supply (warm air) plenum of the primary furnace.
IMPORTANT: Verify beforehand that sufficient clearance is available above air conditioner coils,
etc. If sufficient clearance is not available, air conditioner coil may have to be moved to a second
plenum with diversion baffles for summer use.
2. Attach a 90° sheet metal elbow to one end of a straight 10" pipe of a length sufficient to project
out over the DAKA furnace; insert this 90° elbow into supply plenum of primary furnace with outlet
pointing upward. Slip plenum collar over straight end of 10" pipe and push up tight against supply
plenum for a good air seal.
IMPORTANT: The 90° elbow within the supply plenum forms a venturi to extract air from DAKA
furnace when primary furnace blower comes on. An absence of this elbow will cause back
pressure down the warm air pipe to the DAKA furnace, adversely affecting heat distribution and
possibly damaging the DAKA furnace. If space prohibits installation of 90° elbow as
recommended see Fig. 5 for alternate designs.
3. Using 10" starter collar (13) included, attach another straight 10" pipe to top of DAKA air jacket.
Join it to pipe leading to primary furnace. Supply plenum with another 90° elbow. For best seal,
apply duct tape to all pipe joints. Repeat steps 3 and 4 for second 10"air outlet.
4. Connect cold air return of primary furnace to DAKA furnace blower by means of a minimum
12" pipe joined to the cold air filter box inlet.
NOTE: After attaching warm and cold air supply and return pipes to primary furnace, check entire
system to insure that static pressure remains unaffected. Verify horizontal duct clearances per Fig.3.

daka 832 furnace manual_3-18-13 Page 6 of 14
September 26, 2012, Revised March 18, 2013
B. FOR USE AS A CENTRAL FURNACE (SEE FIG. 2)
1. Install a minimum 16" x 16" plenum on air jacket top, cutting top with tin snips or saber saw
as needed, and using starting collar to attach.
2. Install ductwork with proper clearances to combustibles in accordance with local building
codes.
3. NOTE: A cold air return line must be installed between the cold air return filter box
and the rooms being serviced by the warm air outputs of the DAKA furnace.
VI. CONNECTING DAKA FURNACE TO CHIMNEY
Mount and secure 6" non-galvanized smoke pipe, 24-ga. or heavier, to rear smoke outlet on
DAKA furnace. Continue same gauge single wall pipe to chimney connection, with following
safety rules in mind:
1. A barometric regulator should be installed in smoke pipe at least 18" from furnace, to permit
adjustment of chimney draft to a maximum of .06" water column draft. DAKA Barometric
Regulator No. 283 with adjustable draft setting is available through your DAKA dealer or at
www.dakacorp.com / Energy Division store or call Toll-Free @ 1-800-884-3252.
2. Smoke pipe should maintain a minimum 18" clearance to all combustibles and should never pass
through walls or ceilings; use proper thimbles for those passages.
3. Heat reclaimers, fins or the like should not be used on smoke pipe, as they tend to cool flue
gases and add to creosote formation on stoves and furnaces of advanced airtight design.
4. All joints of chimney connector pipe should be secured with a minimum of three No. 7 sheet metal
screws, and further sealed with furnace cement to maintain good draft. Smoke pipe should
normally be installed with male ends leading from chimney to furnace; should runny creosote be
formed in chimney connector, it will then return through pipe to furnace without dripping out of
joints.
5. Maintain a minimum of 1/4" per foot of pipe rise to chimney connection; the steeper the rise, the
more easily draft will be maintained.
6. Avoid the use of 90° elbows in any chimney connector, as they adversely affect draft. If 90°
elbows must be used, do not install more than two in any chimney connector.
7. Adequate combustion air must be provided in furnace area to prevent poor firing and smoking.
Keep a window cracked open in furnace area, or install minimum 3" vent to bring in fresh air.
VII. OPERATING CONTROLS
A. Snap Disc Fan Control (Marked F120 or F110)
The snap disc fan control (mounted in the J-box extension ring on the side of the DAKA furnace) is
designed to turn on the multi-speed blower on the DAKA furnace whenever the air temperature within
the air jacket exceeds 120°F and turn it off whenever the air jacket temperature falls below 100°F.
This range is built into the snap disc thermostat and cannot be adjusted.
B. Snap Disc Operating Control (Marked L190-20 or L190-2)
This control is a normally-closed switch wired to the front-mounted 50-cfm draft blower. It is
designed to open, or turn off power to the draft blower, whenever the furnace air temperature
exceeds 190°. It will not turn on again until the air temperature falls to 170°. This means that
even if the upstairs thermostat is calling for heat, the draft blower may not run.
