Pyroclassic Fires IV Wood Burner User manual

OPERATING INSTRUCTIONS
Model: Pyroclassic® IV Wood Burner
Pyroclassic fires are unique and work differently from other wood burners.
Please take your time to read through these instructions to maximise the benefits of
your new Pyroclassic IV.
Save these instructions for future reference.
IMPORTANT NOTE
Pyroclassic®fires have been in production for more than 30 years. Our experience, along with
other New Zealand manufacturers, is most issues relating to obtaining maximum efficiencies
come from loading the fire with wet wood (more than 25% moisture content).
The New Zealand Home Heating Association report that as much as 95% of complaints received
are a result of poor fuel.
We strongly suggest you read the 'Firewood' section on page 6 in this booklet.

TOOLS AND ACCESSORIES SUPPLIED WITH THE PYROCLASSIC IV
CURVED RAKE AND SHOVEL
The rake and shovel have curved edges to fit the cylindrical fire
chamber of your Pyroclassic fire. Use the rake to move ash and
hot char inside the cylinder and the shovel to remove the ash
once it has cooled to a safe temperature.
RE-USABLE FIRE STARTERS
A pack of two re-usable fire starters are supplied with your Pyroclassic fire (see section ‘Your first fire’). Soak the fire
starters in methylated spirits and place one in the front of the fire chamber just underneath the front of your kindling.
Once the fire has ignited, use tongs to carefully remove the fire starter and place it somewhere safe to cool down. When
the fire starter is cold, place it back in a glass jar of methylated spirits.
WARNING:
NEVER put fire starters in methylated spirits whilst they are still hot.
NEVER leave methylated spirits near the lit fire.
NEVER put spirits or any liquid fuels directly into the fire chamber.
DIGITAL MOISTURE METER
The moisture meter is intended to be used regularly throughout the drying process, from
when your wood fuel is delivered, right through to just before burning it. It measures the
moisture content (%) in wood and is an essential tool as a fire owner. You MUST burn dry
wood for your Pyroclassic IV to operate effectively. Poor quality, wet wood is the most
common cause of issues with all wood fires and flue systems.
WARRANTY FORMS
Please ensure both copies of your warranty paperwork have been completed. Include your Pyroclassic Fires retailer, fire
installer, wetback installer/plumber (if applicable) and personal contact details. Return one copy to:
Pyroclassic Fires Ltd
PO Box 14057

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 6
FIREWOOD
Any wood burner that is not operating correctly creates high emissions and will not heat your home properly. Simple
methods to ensure clean burning and efficient heating are:
Plan ahead.
Stock up on your wood fuel at least 6-12 months before winter to allow the wood to air dry. Stack wood loosely in a
dry place so air can pass freely through the pile.
Burn dry, well-seasoned wood. Check your wood with the moisture meter supplied as longer drying times may be
necessary.
The ideal size of wood for the Pyroclassic IV is from 25mm-120mm (1” - 5”) in diameter, cut into 300mm-400mm
(12”- 16”) lengths. Note: shorter pieces are less convenient and efficient to use. Let your wood merchant know what
you want for your money.
Do not burn wet or green wood, plastic, domestic refuse, painted or chemically treated wood, plywood, driftwood,
particle board or coal in your Pyroclassic® IV as they will damage your fire.
Burn small, hot fires near the back of the fire chamber.
Observe the position of the load limiter bars in your wood burner to avoid placing too much wood in the fire.
However, it is necessary to stock up the firebox to achieve an overnight burn of 10+ hours.
CAUTION:
THE USE OF SOME TYPES OF PRESERVATIVE-TREATED WOOD AS FUEL CAN BE HAZARDOUS.
DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS TO START OR REKINDLE THE FIRE.
DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS OR PLACE THESE IN THE VICINITY OF THIS APPLIANCE WHEN IT IS
OPERATING.
DO NOT STORE FUEL WITHIN THE HEATER INSTALLATION CLEARANCES.
THIS APPLIANCE SHOULD NOT BE OPERATED WITH A CRACKED GLASS.
THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL TIMES IN ACCORDANCE WITH THESE INSTRUCTIONS.
THERE SHOULD BE NO UNAUTHORIZED MODIFICATION OF THE APPLIANCE.
REPLACEMENT PARTS MUST BE GENUINE PYROCLASSIC FIRES PARTS, OR THOSE RECOMMENDED BY THE
MANUFACTURER.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 7
OPERATING USE AND MAINTENANCE
USE OF TURBOSLIDE
The turboslide covers a hole that allows start up air to enter quickly into the chamber to
ignite your fire. To open the hole, move the turboslide to the left or right. When your fire is
well established (30 –60 minutes depending on wood type), slide the turboslide back into
the middle position. Always keep a small area around the very front of the fire chamber free
of ash and char so the hole is clear and the turboslide can work effectively. Simply push back
the build-up a little with the Pyroclassic rake.
Please note: The turboslide is to be used only for the initial start-up of fires and to help ignite
fresh fuel if required. By following these instructions, you will enjoy low emissions, high
thermal efficiency and conserve your wood supply. Not following these instructions can
result in damage to the air tubes inside the fire chamber and accelerated discolouration of
your flue pipes.
LOADING FIREWOOD
Do NOT try and insert wood sideways. The orientation of the Pyroclassic IV’s unique fire chamber ensures you can only
insert firewood lengthwise. Burning wood end to end and along the grain like this is far more efficient than across the
grain. Wood grows from the ground up, not parallel with the ground!
LOAD LIMITER
Along the top of the inside of the fire chamber is a load limiter. This is designed to restrict
the operator from overloading the fire chamber. A tip for using your Pyroclassic® IV
responsibly (low emissions/no smoky fires) is to burn small, hotter fires. Add wood as
required, this is how you can control the heat output of your fire.
CONTINUOUS AND OVERNIGHT OPERATION
The Pyroclassic® IV is a heat store and small, hot fires store surplus heat in the refractories. The unit then continues
heating like an electric storage heater. There are a few simple steps to follow to ensure your fire burns overnight with a
solid ember bed for relighting the next morning. Firstly, make sure you have a hot, glowing ember bed all the way to the
back of the firebox. Load the firebox with large logs approximately 45 minutes before you go to bed. Open the turboslide
to boost the air supply to the fresh fuel load. When hot, bright flames are well established, close the turboslide. This
method will help you get all the available heat out of your firewood. In the morning, rake hot embers out of the ash to the
front of the firebox. Remember to keep the turboslide hole clear to allow air in to rekindle the fire. Add kindling and a few
larger pieces on top. With the turboslide open, you should have a roaring fire in less than 10 minutes. You may not be
able to maintain an overnight fire with certain soft woods. For more information on how to achieve an overnight burn,
watch our instructional videos online at www.pyroclassic.co.nz.
AIR SUPPLY
The room or space containing this appliance needs no additional ventilation unless a draught stabilizer is fitted, in which
case a permanent opening of at least 1,500mm2should be provided. Any air opening must be kept clear from
obstructions. Due consideration should be given to air requirements for any other appliances in the same room or home,
such as heat transfer kits, kitchen range hoods, laundry dryers, bathroom vents etc.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 8
OPERATING USE AND MAINTENANCE
REFUELLING ONTO A LOW FIREBED
The wood fuel inside a Pyroclassic® fire burns best on a thin bed of ash and hot coals. Refuelling must be carried out onto
a sufficient quantity of glowing embers so the new fuel will ignite. Add suitable kindling if necessary. If a new fuel load is
left without suitable ignition then a buildup of unburnt volatile gases can occur. This puts stress on the unit, which can
lead to an internal explosion when these gases do combust. Always ensure adequate ignition and combustion of fuel and
use the turboslide as instructed. If there is insufficient burning material in the firebed to light new fuel, excessive smoke
emission can occur.
THE PYROCLASSIC® IV IS SELF-REGULATING.
The vigorous fire towards the front of the chamber automatically slows down as the burning advances towards the back
of the fire chamber. Each cycle ends with ash and hot ember at the far end of the chamber. The Pyroclassic® IV is
designed to save on firewood and keep emission levels to a minimum by storing surplus heat in the cylinder, which
normally goes up the flue. This heat is released into the room even when the fire is low at the end of each burn cycle.
REFUELLING and using your PYROCLASSIC CURVED RAKE
Use the rake to evenly distribute the hot ember and ash along the base of the fire chamber, ensuring there is sufficient
hot ember at the front to provide adequate ignition to the fresh fuel load. Load the fuel so one end of each log is in
contact with the back wall of the firebox. If you keep your fire burning under the air tubes, this will ensure the maximum
amount of heat is captured within the ceramic cylinder.
Please Note: Only use Pyroclassic Fires tools as using others may cause damage to the cylinder. Always take care not to
heavily impact the ceramic surface.
DOOR/DOORKNOB
DO NOT run the fire with the door open. It will never reach the correct operating temperature and this can be very
dangerous.
The door seals with little pressure so it may be hard to open when the unit is very hot. The door knob is a great indicator
of what is going on inside your fire so if you find the door knob is too hot when you go to refuel, you are probably trying
prematurely. Do not overtighten the door knob as it can cause damage to the door gasket and fixing screws.
If your door knob is starting to show signs of charring, you are probably burning your fire too close to the door. Try closing
the turboslide sooner and letting the fire burn further back in the fire chamber.
Do not lean on the door or use it to help you stand when it is open as this can cause the door to move. If your door does
become misaligned, loosen the top bolt going horizontally through the hinge bar and lift the door back into the correct
position and retighten the bolt.
AIR INLETS
Do not block any fixed air inlets as this will affect the fire’s performance and may cause permanent damage.
BURNING WITH THE PYROCLASSIC® IV
Solid wood must change to gas and vapour before any burning can take place. This change occurs by heating wood to
high temperatures, making gas fuel. Low temperatures will make smoke and tars that are simply unburnt fuel. The
Pyroclassic® IV is a North/South burning fire, which means the fire is started in the front of the fire chamber and
continues along the length of the wood to the rear. To get the most out of your firewood, ensure logs are placed
lengthways into the fire chamber, not sideways. To achieve a high temperature in the fire chamber quickly, use the
turboslide and dry wood. You will never get the fire to burn correctly if you try starting fires with green or wet wood. The
only fuel authorised for use with this appliance within Urban Clean Air Sheds and Smoke Control Zones is well-seasoned
wood with a moisture content of 25% or less, 12-18% is ideal.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 9
GREASING THE DOORKNOB SPINDLE
A small amount of graphite grease should be applied to the spindle of the doorknob, usually twice a year is sufficient.
Ashes from the fire have a gritty texture and over time this can cause wear on the doorknob spindle. Using a matchstick
or cocktail stick, lubricate the groove in the first thread. Use the door grease sparingly as too much will melt and dribble,
causing an unsightly stain. Remove any excess before relighting the unit.
CLEANING THE DOOR GLASS
The air wash over the door should keep the glass clean. A dirty glass is a sign of a fire that is not getting hot enough,
normally caused by trying to burn unseasoned or unsuitable wood. If your door glass needs cleaning, scrunch up two
pieces of damp newspaper, dip one in cold fire ashes and rub over the inside of the glass. Use the other to rub over the
glass to remove the dirt from the ash. Get into the habit of cleaning it regularly as this will maintain the glass and prevent
ashes from fusing. Clean the glass when it is cooler, such as in the morning before rekindling the fire. If your fire is
operating correctly, your door glass should have a light, white cloudy appearance.
Please note: This appliance should not be operated with a cracked glass.
FLUE CLEANING/CHIMNEY SWEEPS
The Pyroclassic® IV flue will only clog up if you burn wet wood, fuel with an inadequate air supply, or if the fire chamber
does not reach normal operating temperature. We recommend your flue be swept at least once a year, or more
frequently if necessary (i.e. if you notice smoke coming out of the open door). Pyroclassic fires are different from other
wood fires and should be swept from the top down into a tray at the bottom of the flue; if excess buildup has occurred
then it may be necessary to remove the top plate from the fire to empty out the top chamber. Do not allow the chimney
sweep to dismantle the flue or take the cooktop off unless they are sure they know what they are doing.
Please ensure whoever is sweeping your flue has watched our ‘How to clean the flue of a Pyroclassic fire’ video online at
www.pyroclassic.co.nz.
Please note: Before relighting the fire after a prolonged shutdown, check the flue for any blockages, such as birds nesting
in the chimney.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 10
LIGHTING YOUR FIRST FIRE
Do not be alarmed if your fire does not perform well or even goes out during your first fire. It can take several fires to fully
cure the ceramic cylinder before full performance can be achieved. You may notice a small amount of moisture appear
under your fire on the hearth, this is completely normal.
Allow adequate ventilation when you light your fire for the first time as smoke and odour are released as the special heat-
resistant paint cures. This will not last long and should not happen again.
HOW TO LIGHT YOUR FIRST FIRE
1. Soak the re-usable fire starters in methylated spirits.
2. Slide the turboslide to the far right or far left position.
3. Place DRY kindling and a few small logs lengthways in the front of the fire chamber, leaving a clear space in front of
the air inlet hole.
4. Place a soaked fire starter just under the kindling at the front of the fire chamber and light it. Close the door.
5. Once the fire is well established and you have a nice bed of hot embers, move the turboslide to the central position
to cover the air inlet hole.
6. When opening the door to load more wood, slide the turboslide to the far left or right open position and continue
from Step 5.
A video of how to light and maintain a fire in a Pyroclassic IV can be found on our website –www.pyroclassic.co.nz
Please note: The fire starter can be retrieved from the fire once it has stopped burning. Use metal tongs and place the fire
starter on a non-combustible surface, i.e. a block of stone, concrete or tile. When it is cold it can be stored in a jar of
methylated spirits, ready for your next fire.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 11
TROUBLESHOOTING
If your query is not listed below, visit the ‘Help Centre’ at www.pyroclassic.co.nz.
SLOW START-UP
Open the turboslide by moving it to either the left or right position.
Check the start-up hole (behind the turboslide, inside the chamber) is free of ash and char and rake back any build-
up.
Check for air leakage around the cooktop, around the flue collar, and in the flue pipe joints. Air bypassing the fire
chamber reduces draft. Repair air leaks.
This could be from using large or wet logs, or loading fuel on too few hot coals. Use dry kindling to start the fire
quickly. Do not use wet fuel (see the Firewood section in this booklet for more information).
Insufficient draft: Review chimney construction and investigate air pressure levels in the home.
Warm, humid conditions outside or an inversion layer: Wait until the flue pipe is hot.
DENSE SMOKE
This is likely caused from the burning of plastic materials, fire retardant treated wood or high resin content wet wood.
Burn only well-seasoned wood and ensure it is positioned lengthwise in the cylinder.
EARLY MORNING PALE BLUE SMOKE
This is caused by burning off small creosote deposits formed by premature banking of the fire the night before.
SMOKE ENTERING THE ROOM
Negative pressure in the room, possibly caused by a household electric exhaust fan or severe pressure difference in a
windstorm: Open a window to equalise the pressure.
Severe down draft due to surrounding structures, hills, trees or roof layout. If you think your home is suffering from
down draft, download the troubleshooting info sheet from our website –www.pyroclassic.co.nz.
Flue is clogged: Clear the obstruction and investigate the cause.
GASES & SMOKE ENTERING THE ROOM WHEN THE DOOR IS OPENED
The most common cause of this issue is a clogged flue. Get a sweep in to clean your flue, ensuring whoever is
sweeping the flue has watched the Flue Cleaning help video online at www.pyroclassic.co.nz.
Opening the door during the maximum degassing of fuel. Wait until the flames disappear.
This can also be indicative of a very cold flue temperature. Allow the initial startup fire to warm the flue pipes.
HIGH FUEL CONSUMPTION
Loading door is not airtight: Check the gasket.
Incorrect operation: The Pyroclassic is a heat store, so try adding logs less often and burn the fuel further back in the
fire chamber.
You might be leaving the turboslide open for longer periods than intended. The turboslide should only be used when
lighting the fire and for igniting a new fuel load.
High flue draw: investigate cause and consider an H type cowl if consumption is excessive.
LOW WATER HEATING CAPACITY
The most likely cause of this is a low temperature, poor performing fire. A video illustrating the best way to light and
maintain a fire in a Pyroclassic IV can be found online at www.pyroclassic.co.nz. If your fire continues to
underperform, it could be due to one of the points raised above.
Your plumber may have incorrectly fitted the Hotflow wetback. Get your plumber back to check the layout as the
system must have continuous rise. Wetback information can be downloaded from our Resources section on our
website –www.pyroclassic.co.nz.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 12
TROUBLESHOOTING
NOISY OR PULSATING WATER HEATING
Get back your plumber/wetback installer to check the layout as this is most likely an improperly constructed water-
heating circuit. A copy of the Wetback Installation Instructions can be downloaded from www.pyroclassic.co.nz.
DOORKNOB CHARRING
The expected lifespan of a doorknob is somewhere between 4 - 10 years depending on how the fire is operated. There
are two typical causes that lead to premature failure of the doorknob:
1. Excessive charring on the back of the knob due to high levels of concentrated heat from burning wood too close
behind the door area.
2. The door being overtightened when it is closed which in turn leads to it being very tight to open once the fire is hot.
Continued overtightening causes the screws to weaken and then come loose and break away from their fixings.
To avoid these issues and extend the lifespan of the doorknob, keep a clear area of approximately 10cm in the front of
the fire chamber and maintain your fire underneath the air tubes. This will give you the additional benefit of letting the
cylinder absorb the maximum amount of heat from your fuel load. Only tighten the door enough for the rope to make a
contact seal, further cranking of the door knob
CRACKS IN THE FIRE CHAMBER
Due to the fire chamber being cast as a one piece cylinder it goes through some expansion and contraction every time it
is heat cycled and this results in different levels of cracking. This is just the cylinder relieving its inert tension and has no
effect on the operation, performance, or useful life of the unit. For more information on this topic, watch our ‘Why are
there cracks in my cylinder? video, online at www.pyroclassic.co.nz.
BACK PUFFING OR MINOR GAS EXPLOSION
Rake not used to bring hot char forward or burning wood at the wrong end. Use the rake as per the operating
instructions on page 8 of this booklet.
Turboslide not opened or blocked after reloading large, cold logs.
An insufficient bed of coals needed to ensure the adequate ignition of a fresh fuel load.
Wood fuel which is too wet for burning. Split a large log and spike the center with the moisture meter provided with
your Pyroclassic fire. Moisture content should be less than 25%, ideally 12% - 18%.
An explosive substance such as a battery or aerosol container loaded into the fire chamber. This is VERY dangerous,
do NOT do this.
FIRE WILL NOT BURN OVERNIGHT
Turboslide left open. See page 7 in this booklet for more information on how to use the turboslide effectively.
Loading door not airtight.
Insufficient fuel load. The Pyroclassic IV burns approximately 1.1kg of wood per hour. Softwoods are lighter and
therefore less fuel can fit into the cylinder, making it more difficult to achieve overnight burns. Well-seasoned hard
woods are ideal for extended burn times because of their density. See ‘Pyroclassic Fires Customer Handbook’ for
more information.
If you are struggling to get your Pyroclassic fire to burn overnight, it is worth watching our videos online at
www.pyroclassic.co.nz, which illustrates how to achieve an overnight burn and a typical overnight burn cycle.
DOOR LOCK HARD TO OPERATE
Apply a small amount of high temperature grease to the thread as per instructions on page 9. Grease with graphite or
molybdenum disulphide only.
You may be overtightening the door spindle thread. The door on a Pyroclassic IV seals with minimum pressure. Do not
overtighten this door as this will shorten this life of the handle and gasket.
ASH SPILLS & DE-ASHING
Make sure you have a metal (non-combustible) ash container with a lid and store it outside on concrete or bare ground.
Use the Pyroclassic shovel to empty the fire chamber when it is cool. Be careful as ash almost always contains some hot
ember. Never use a vacuum cleaner. Pot ash can be great for your garden if your soils are acidic. Use only ash from a
cooled fire which used good quality wood.

Pyroclassic Fires Operating Instructions | Updated July 2016 | V.2 | 13
SAFETY NOTES
FIRES CAN BE DANGEROUS
Always use a fireguard in the presence of children, the elderly or the infirm. In New Zealand and Australia, AS/NZS
2918:2001 guidelines should be followed. In the UK the fireguard should be manufactured in accordance with BS 6539 –
Fireguards for use with solid fuel appliances.
OVERFIRING
It is almost impossible to overfire your Pyroclassic® fire beyond its design capacity as the firebox will withstand
temperatures in excess of 1500oC. However, if any part of the unit starts to glow red, ensure the turboslide is closed and
allow the fire to die down. You will be unable to refuel it during this period due to high temperatures around the loading
door.
FUME EMISSION
If properly installed and operated, this appliance will not emit fumes. Persistent fume emission must not be tolerated as it
indicates a problem and the following actions must be taken:
Open doors and windows to ventilate the room.
Let the fire die out or safely remove and dispose of the fuel in the appliance.
Check the chimney for blockage and clean if required.
If necessary, seek professional advice.
IN THE EVENT OF A FLUE/CHIMNEY FIRE
Raise the alarm and let others in the house know.
Call the relevant emergency services.
Move furniture and rugs away from the appliance if possible.
Get out.
Thank you for purchasing a Pyroclassic IV, we hope it fulfils all of your expectations and more!
