We have just had a minor gas explosion/back puffing in our Pyroclassic. Why has this happened?
This could be caused for the following reasons:
- Rake not used to bring hot char forward causing wood to burn at the wrong end. Use the rake as per Operating Instructions.
- The Turboslide was not opened after re-loading large, cold logs.
- The burning of an explosive substance - battery, aerosol container, etc. DO NOT DO THIS!
- There was an insufficient bed of coals to ensure adequate ignition of a fresh fuel load.
- Too high moisture content of wood fuel. Split one of your logs in half and use your moisture meter to test the wood.
As a point of caution you should never insert a fresh log which is too large or placed in the fire too late to ensure a flaming combustion, doing this will cook the wood fuel on the remaining embers releasing unburnt volatile gases into the combustion chamber which will eventually reach a point of ignition, this can result in a sizable explosion inside the fire chamber and may cause damage to the unit.
Why is smoke coming from my Pyroclassic fire into my room?
There are a few reasons why this could be happening:
- Negative pressure in the room - this can be 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.
- Most commonly, this is an indication your flue is blocked. Clear the obstruction and investigate the cause. Check the moisture of your wood and make sure you are burning good, dry wood. The flue pipe can block very quickly if you are burning wet or gummy wood. Make sure you are using a reliable chimney sweep as the Pyroclassic is different from other wood fires.

Can I use other tools in my Pyroclassic fire chamber?
Depending on how the fire is used, the surface of the cylinder can wear and erode over time. This can be accelerated through using the wrong tools, such as a flat shovel to remove ash (shown below). As you can see, this has resulted in two carved grooves in the ceramic. Although this is not ideal, it is not of a major concern as the cylinder wall is over 35mm thick so it will not compromise the integrity of the structure and the surface can easily be repaired through the application of veneering cement, which can be purchased from our online shop.
What proportion of heat comes from the back of the fire and the flue in comparison to the front and sides?
This is a difficult question to answer. Most of the radiant heat from the fire comes from the top plate (more front than back) and the door area. The cooler convection heat comes off the extruded coloured panels around the sides and the front of the fire.
By comparison, the heat from the rear of the unit is much less than that from the other sides but it can still get to quite a temperature around that area. What that temperature is can vary depending on what the fire is doing, it is almost never a static output.
Why have Pyroclassic fires dropped from No.1 on Consumer NZ tests on their last report?
Consumer Magazine recently changed the way fires are rated. This has caused some issues across the industry as what were considered the 'best' fires are now not rated near the top...like the Pyroclassic IV. They have changed the weightings of their review to focus more on price for output over emissions and efficiency as they believe this is more in line with what the customer wants.
This has resulted in a list which is more about heat output for dollars spent rather than which fires actually perform the best. It also makes no provision for servicing costs, warranty duration or expected life of the appliance and its components.
The statement we have printed in our marketing material - 'Consistently chosen as the top pick for wood fires in all Consumer reviews' refers to the consumer reviews across various formats in NZ, Australia and the UK over the last 30 plus years including true consumer feedback.
What type of flue do you recommend
We recommend a 150mm flue kit for your Pyroclassic Fire.
As we are a carboNZero certified organisation, we are not keen to support the unnecessary freight of bulky flue components great distances when there are comparable products available from reputable manufacturers in your locality. Please speak to your local Pyroclassic agent about the Flue Kit options available to you in your area.
Can I make modifications to my authorised woodburner?
Authorised woodburners have been designed and tested to ensure that they meet emissions and efficiency limits set out in the National Environmental Standards for Air Quality. Modifications may result in more emissions being discharged or a decrease in efficiency, which will invalidate the authorisation.
Modifying your woodburner without the advice of the manufacturer may also create a fire hazard or other safety risks.

Why are gases and smoke entering the room when the door is opened?
The most likely reason for this is that your flue is clogged and may require sweeping.
Other possible causes:
- You could have a very cold flue temperature. Allow initial start up fire to warm flue pipes.
- Loading door opened during maximum degassing of fuel. Wait until flames disappear.
Why has the top plate dropped down at the front and ridden up at back and the insulating wool is visible?
The top plate may have dropped due to the front layers of insulating gasket moving out of position. This could be for a number of reasons but most often is due to a disturbance during sweeping.
If the layers of white gasket material are still intact they can be relocated back into position. If not then new sealing strips can be ordered to replace these from our online shop.
Why is there pale blue smoke early in the morning?
The Pyroclassic is burning off small creosote deposits formed by premature banking of the fire the night before.
