INTRODUCTION
The Empyre Elite XT Hot Water Furnace
You have selected one of the best wood stoves/furnaces
on the market today! It has been specially designed to
produce highly efcient heat with emissions well below
environmental standards, and we are proud to offer a 10
year limited warranty!
To ensure maximum benet from your new Empyre Elite
XT furnace, read the Installation and Operation Instruction
Manual cover to cover and follow all instructions carefully.
The Empyre Elite XT furnace has been designed for outdoor
installation and has also been tested to meet UL Standard
391 - 2006/726-06 Standard C22.2 No.3 and CSA B366-
1-M91forindoorcentralsolidfuelredfurnaces,therefore
it may be installed indoors. It is ideally suited for both
domestic and commercial use.
Please keep this manual for future reference.
How The Empyre Elite XT Works
TheEmpyreEliteXTusesaprocesscalledwoodgasication
to produce highly efcient combustion in the furnace’s
dual burn chambers. (1) Wood in the rebox burns from
thebottom,dryingthetoplayerofwoodinthereboxand
forcing gases and exhaust into the lower burn chamber. (2)
In the brick-lined lower chamber, these volatile gases are
burned at temperatures as high as 2000°F (1093°C).*
Therebricklininginbothburnchambersabsorbstheheat
and maintains burn chamber temperatures for consistent
gas combustion. This high-temperature gas combustion
signicantly lowers emissions, prevents creosote buildup,
and minimizes ash buildup in the unit. (3) After passing
through the burn chamber, exhaust air escapes through
multiple ues running through the water jacket, heating
thewaterquicklyandefciently.(4)Theexhaustcoolsasit
passesthroughtheues,andwhenitleavesthechimney,
temperatures have fallen to 350°F (177°C).
*varies based on fuel type, burn rate and other conditions

INSTALLATION
12 EMPYRE ELITE XT INSTALLATION AND OPERATION MANUAL
Outdoor Furnace Installation
We recommend that the furnace be installed by a
qualied installer.
1. Position furnace on pad. Note: Lift only by top lifting
hook or bottom forklift guides. Use caution! Furnace
is heavy.
2. Identify and remove components shipped in the
furnace,inreboxorrearoffurnace:ashrake,ue
clean out tool, water level indicator and Empyre
System Optimizer.
Outdoor Chimney Installation
Install a 1 inch (2.54cm) insulated chimney that is listed
to ULC-S610 and ULC- S604 standards. Apply a bead of
high temperature silicone on the outside of the chimney.
For tall chimneys, chimney braces are recommended. It is
recommended that a minimum chimney length of 5 feet
(1.52m) is used.
IMPORTANT: A spark arrester must be installed if the
EmpyreEliteXTfurnaceisusedinahighreriskarea.
Indoor Chimney Installation
Wheninstallinganewchimneyue,besuretoobserve
local building codes and the National Fire Protection
Association rule: the top of the chimney must extend at
least 3.0 feet (0.9 m) above the highest point where it
exits the roof and be at least 2.0 feet (0.6 m) taller than
any point of the roof within 10.0 feet (3.04 m).
For a new chimney, use an insulated stainless steel
system that conforms to type HT (High Temperature)
requirements of UL 103 and ULC S629 and complies with
the requirements of Chapter 11 of NFPA 211, Standard
for Chimneys, Fireplaces, Vents and Solid Fuel-Burning
Appliances. Sections of stove pipe (minimum 24 gauge
black or blued steel) may be used from the furnace to the
insulated chimney. Note: avoid using 90° Elbows; 45° is
recommended.
A chimney cap must be installed.
Lining masonry chimneys with a stainless steel liner is
recommended.
Furnace Flue Diameter
Empyre Elite XT 100 6 inches (15 cm)
Empyre Elite XT 200 6 inches (15 cm)
IMPORTANT: DO NOT install furnace in a mobile
home or trailer.
Supplying Make Up Air
Fireplaces, other furnaces, clothes dryers, exhaust fans,
and other appliances all draw air from the room in which
they are located. The Empyre Elite XT adds to that draw,
making it important to ensure there is an adequate
source of fresh air to offset these demands. Otherwise, a
negative pressure may be created in the room and starve
combustion in the furnace.
1. Determine the volume of space (cubic feet) in the
room.Includeinthecalculationadjacentroomsand
areas not closed off by doors.
Volume (CF) = Length (ft) x Width (ft) x Height (ft)
2. Determine the air input requirements of all applianc-
es in the space. Add them and round the total to the
nearest 1000 BTU per hour. The Empyre Elite XT 100
requires 85 CFM (cubic feet/minute), the Elite XT 200
requires 120 CFM.
3. Determine whether the space is ‘conned’ or ‘uncon-
ned’bydividing thetotalvolumeoftheroombythe
total input requirements for all appliances in the room.
a. If the result is equal to or greater than 50 CF/1000
BTUperhour,thenconsiderthespace‘unconned.’
b. If the result is less than 50 CF/1000 BTU per hour,
thenconsiderthespace‘conned.’
4.For an ‘unconned’ space in a conventionally con-
structed building, the fresh air inltration through
cracks around windows and doors NORMALLY pro-

INSTALLATION
EMPYRE ELITE XT INSTALLATION AND OPERATION MANUAL 13
vides adequate air for combustion and ventilation,
and therefore no additional make up air is required.
5. Fora ‘conned’space oran‘unconned’spaceina
building with unusually tight construction, an addition-
al source of make up air is required. Please consult an
HVAC professional to determine the best way to supply
make up air for this type of installation.
Important: Furnace room must never be in a negative
pressure condition. Negative pressure could result in
smoke in the room.
Low Water Temperature Protection
IT IS THE RESPONSIBILITY OF THE INSTALLER TO
PROVIDE LOW WATER TEMPERATURE PROTECTION
IN THE DESIGN OF THE HEAT DISTRIBUTION SYSTEM
The Empyre Elite XT furnace is no different than an oil
boiler or gas boiler in that condensation of the products
ofcombustionwilloccurifuegasescomeincontactwith
a surface that is less than 140°F (60°C). With an oil or
gas boiler the rate of fuel and consistency of the fuel is
automatic, so if the temperature of the water in the boiler
falls below the desired setting the burner comes on auto-
matically raising the water temperature. The Empyre Elite
XT requires an automatic protection from low water tem-
perature because of the manual fuel feed.
Condensation (water) in the boiler tubes will cause corro-
sion and premature failure. The ESO, as installed in Fig-
ures 1-3, pages 14 & 15, gives the Empyre Elite XT excel-
lent protection from low water temperatures.
Empyre System Optimizer
The Empyre System Optimizer (ESO) is designed with a low
loss header which includes a Danfoss VTC valve, complete
with a pump ange and bypass piping. The Danfoss
VTC tempering valve was selected for its simplicity and
reliability.
The Empyre System Optimizer is mandatory on all Empyre
Elite XT installations in order to maintain the warranty.
How the ESO and Valve Operates
The Empyre System Optimizer provides a constant
circulation of water through the boiler and the Danfoss VTC
tempering valve. Water is drawn off the low loss header by
the building piping system and returned to that same loop
where it mixes with the water in the low loss header. Before
it reenters the boiler, it passes through the tempering valve.
If the water entering the valve is too cold, the valve starts
to slow the water returning and mixes it with water coming
directly from the boiler. If the return water temperature
drops below 140°F (60°C) the valve will stop this cold
water from entering the boiler. The valve will open again
when the boiler water rises in temperature.

IMPORTANT:
1. Use only clean, filtered water in the Empyre
Elite XT. Add Pro-Fab approved water
treatment to the water to prevent corrosion
(available from your dealer). For amount of
treatment to add follow instructions on the
container.
First Fill
1. Attach a garden hose, with two female ends, from
the water supply to the drain (see pg 9 ). Turn on
the water and open drain valve.
2. Check all lines and connectors for leaks.
3. Open the SUPPLY valve (see pg 9) at the furnace
and let water run for 2 minutes and then close it.
4. Now open the RETURN valve (see pg 9) at the furnace
and let water run for 2 minutes and then close it.
5. Repeataboveprocedure3to4timesduringlling
of the furnace. Alternating between lines will ensure
that most of the air is bled from the system.
6. When the level indicator shows ADD, shut the drain
valve, shut off water and disconnect the garden
hose. Note: hot water level is higher than cold
water level.
7. Heat furnace to operating temperature (see ‘Starting
the Fire’ below). Check water level again.
8. Add Pro-Fab approved water treatment through
vent opening, Figure 1.
9. Check water level when water temperature is
170°F (77°C) and add water until level indicator
shows full.
Maintaining Proper Water Level
When the water level is low, the Empyre Elite XT may be
lledortoppedupthroughtheventopening,Figure1.
Starting the Fire in the Hot Water Furnace
Once the Empyre Elite XT has been properly installed, all
connections checked thoroughly and the water system
islledtotheproperlevel,theunitisreadyforstarting
are.
1. Switch blower on.
2. Place some dry split kindling in the centre of the
rebox,ontopofsomepaper,andignite.
3. Once the kindling begins to burn, add larger pieces
ofwooduntilthereburnsbriskly.Stirthereuntila
sufcientcoalbedisobtained.Donotlltherebox
of the furnace to capacity until the water in the
furnace is hot.
DO NOT USE THE DOOR AS A LEVER TO FORCE WOOD
INTO THE FIREBOX! PIECES OF WOOD SHOULD NOT
PROTRUDE INTO THE DOOR FRAME AREA.
NOTE: The Empyre Elite XT has been pressure tested at
the factory for water leaks. Some condensation may be
observedinthereboxwhilethefurnaceiscomingupto
temperature after the water has become completely cold.
Toavoidcreosotebuildupinthereboxandfurnace,burn
only seasoned wood in the Empyre Elite XT.
Maintaining Proper Water Temperature
Do not operate the furnace below a temperature of
165°F (74°C). This is important in order to maintain
the warranty.

OPERATION
EMPYRE ELITE XT INSTALLATION AND OPERATION MANUAL 17
Understanding the Gasication Process of
the Empyre Elite XT Wood Furnace
Wood gasication is an amazingly clean burning and
efcientprocess!Itisaprocesswheremuchofthesolid
fuel is converted to gases. These gases ignite and burn
along with the solid fuel. A large percentage of wood is
converted into gases. In order to burn these gases there
must be the right amount of air, as well as temperatures of
wellover1000ºF(538ºC).Gasicationisaccomplishedin
the Empyre Elite XT furnace because:
a)airowisengineeredtoprovidethecorrectamountof
under re and over re air. This setting is calibrated for
burning seasoned wood;
b) temperatures high enough to burn the gases are reached
intheinsulatedchamberbelowtherewood.
Akeyfactorinthegasicationprocessisthewooditself,
the type of wood, the moisture content, diameter, length
andplacementintherebox.TheEmpyreEliteXTfurnace
is not difcult to operate using seasoned wood and by
using the following guide it will also work well even when
using less than ideal wood.
The gases in the wood are released when the wood surface
isexposedtothere.Themoresurfaceareaofapieceof
wood that is exposed and the drier the wood is, the faster
the gases are released. Example: A small DRY piece of
burning rewood will release gases much faster than a
largeWETpieceofrewood.
Scenario1:inthecaseofthesmallDRYpieceofrewood
which has a lot of exposed surface area, the gases are
releasedrapidlyandthereburnsveryhotbutitisstarving
for air due to the high volume of gases. This will eventually
create smoke.
Scenario2:inthecaseofthelargepieceofWETrewood
that, in proportion to its mass, has little surface area and
will release gases slowly. In this case there is too much air.
Theairisnowcoolingthereresultinginbluesmokeand
very little heat.
Generallyspeaking,whenburningextremelydryrewood,
pieces should be over 5” (12.7 cm) in diameter. If using
high moisture wood, use pieces that are less than 5” (12.7
cm) in diameter. It is good to mix the dry and wet wood
when possible. When using the recommended seasoned
wood, where the moisture content is between 19% and
25%, the diameter of the wood is not that important.
Scenario1isalsocreatedwhenstirringahotre.Scenario
2isalsocreatedwhenrewoodistooshortinrelationto
thelengthoftherebox.Correctlengthofrewoodforthe
Empyre Elite XT 100 is 18” - 25” (45.7 cm - 63.5 cm), the
Elite XT 200 is 20” - 28” (50.8 cm - 71.2 cm).
Stack wood pieces side by side. If pieces are short place
them end to end making one long piece. Firewood should
be centered front to back over the brick slots.
Scenario 2 is also created when wood bridges in the
rebox.Thisisoftenduetowoodwithhighmoistureor
lack of careful placement of the wood. Scenario 2 is also
created when starting up a cold furnace. Only a small
amount of wood is burning with a lot of excess air.
Identifying Smoke Verses Condensation
Mostly the exhaust from the chimney will be clear. There are
times soon after loading the furnace when a gray vapour
may appear. This vapour disappears soon after leaving the
chimney. This vapour is moisture being released from the
wood. Smoke is more blue in colour and will not disappear
as quickly as the gray vapour. On a cold winter day what
looks like smoke may only be vapour.
Loading Wood into the Firebox
1. The right time to add wood is when there still is a good
layer of charcoal or wood left, but not so much that it
isdifculttostir.
2. Using the ash rake, gently pull the charcoal away from
the back of the rebox. Stir the charcoal sufciently
so that ash falls down through the brick slots. Always
ensure that the brick slots are not blocked by ash
buildup.Placewoodintotherebox,DONOTthrow,as
this may damage the brick lining.
Correct:
Thereboxshouldbeloadedwith
wood of proper length. This will
lengthen the burn time.
Incorrect:
Thereboxlooselylledwithirreg-
ular pieces of wood will decrease
burn time and may cause unneces-
sary bridging.
Larger diameter and irregular shaped logs are more
likely to cause wood to hang up or ‘bridge.’ Place the
larger logs on top.
3. Loadwoodintotherebox.
 Centrewoodintherebox.Thereshouldbeagap
of several inches between the wood and both
the front and back of the rebox. Placing wood
up against the back of the rebox can result in
unburned wood which can cause logs to hang up.

OPERATION
18 EMPYRE ELITE XT INSTALLATION AND OPERATION MANUAL
4. Forthe most efcient burn alwayskeepthe brick
hotbymaintainingwoodintherebox.
5. DO NOT cover the brick slots when placing wood
intotherebox.
Daily Routine
Morning Loading:
Load wood into the unit as described above.
Late Afternoon Check:
Checktheunittoensurethereissufcientwoodtoburn
untiltheendoftheday.Loadjustenoughfueltoensure
abedofburningcharcoalisinthereboxpriortothe
night loading.
Note: The rebox is hottest when the wood has burnt
down to a bed of charcoal. When the primary chamber
has burnt down to this level, the rebox will dry out
and burn most of the accumulated creosote on the
walls. If the primary chamber is full all of the time, the
temperatureinthereboxstaysquitecoolandcreosote
may build up on the walls.
Night Loading:
Rakethecoalandashfromtheperimeteroftherebox
and especially from the back wall of the chamber where
ash tends to build up. With the ask rake, pull the ash
and charcoal away from the walls. The force of the fan
will blow the ash into the lower chamber on its own. If
this is done every day the ash should fall through the
slots easily.
Load wood into the unit as described above.
Cleaning Out Ash
Firebox and Secondary Burn Chamber
Ash in the secondary burn chamber should be cleaned
out weekly or as necessary, depending on fuel quality
and burn rate. Clean ash out of the secondary burn
chamber rst. Then clean the rebox. Otherwise hot
wood coals will be scraped out of the secondary burn
chamber along with the ash.
To clean ash out of the rebox, gently rake it into the
secondary burn chamber through the opening in the
bottomoftherebox.Itisimportanttorakeashbuildup
awayfromthebackwalloftherebox.
1. Dothiswhentherehasdieddownbeforereloading
furnace. Switch blower off.
2. Open ash clean out door.
3. Pull out ash tray.
4. Reach the ash rake to the back of the chamber and
pull ash forward into the ash tray. Do not scrape all
of the ash into the ash tray. It is recommended to
leave1”-2”(2.5-5.1cm)ofashcoveringtheoorof
therebox.
5. Firmly close and latch ash clean out door.
6. Switch blower on.
Flues and Chimney
Switch furnace off.
For highest efciency clean the heat exchanger ues
weekly or as necessary.
1. Clean ash from secondary burn chamber before
cleaningues.
2. Removeuecleanoutcover(seepage9).
3. Push brush completely through ues. Should the
brushbetoodifculttopushthrough,thenrstpush
the rod through and pull from the other end.
4. Inspect and clean any buildup in the exhaust area.
5. Install clean out covers and secure rear access door
latch with bolt and tighten with wrench.
6. Open ash clean out door and ensure the ash is
clearedfromtheues.
Switch furnace on.
Disposal of Ash
Ashes should be placed in a metal container with a tight
ttinglid.Theclosedcontainerofashesshouldbeplaced
onanoncombustibleoororontheground,wellaway
fromallcombustiblematerials,pendingnaldisposal.If
the ashes are disposed of by burial in 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 vapours condense on
therelativelycoolreboxwallsofaslowburningre.As
a result, creosote residue accumulates on the rebox
walls. When ignited this creosote makes an extremely
hot re. To reduce the amount of creosote, a small
intensereispreferrabletoalargesmolderingone.
Fire Brick and Insulation
The secondary burn chamber of the Empyre Elite XT high
efciencyfurnaceislinedwithhightemperatureinsulation.
It is designed to sustain high furnace temperatures and
regularoperationformanyyears.Theoorofthereboxis
lined with brick. To see signs of wear and cracking of the
brick is normal.
