  1. Can you configure the flue to have an offset so it goes out the wall behind the fire rather than the roof? 13/12/2018

    Yes, offset bends are available for the flue systems. The best option would be to speak with a local installer who can give you specific advice about a flue system to suit your home.

    Do note that a general rule of thumb is to try and avoid having any offsets in the first length of flue pipe, no more than a 45 degree angle and no more than 600mm centre to centre of the offset. Offsets do require more maintenance with cleaning etc. and can have adverse effects on the fires performance versus a typical vertical flue.

     

  2. Why does my Pyroclassic not get as hot as traditional 'black box' style wood fires? 13/12/2018

    The Pyroclassic is not a conventional radiant heater. As with all fires it can only generate the heat available from the fuel loaded into it and a single kilogram of wood fuel, soft or hard wood, carries the same calorific value by weight, so if a 'black box' fire is using 3kgs an hour of fuel and yours is using 2 then the other has 50% more heat being generated during the same period.

    A percentage of the heat from a 'black box' wood fire will be lost up the flue that would normally be captured in the ceramic cylinder of the Pyroclassic. However, this doesn’t generate more heat, it just recovers some of what might have been lost.

    If you want more heat then more fuel and air is the way to generate it. Load an extra piece of fuel in each time and leave the Turboslide open for a little longer, this will build more heat quicker and get the cylinder up to a higher temperature. 

    The maximum temperature wood fuel can combust at is 1100c and the cylinder wall in your Pyroclassic is capable of withstanding temps over 1500c so don’t worry about getting your fire too hot. The other components like the first section of flue and the coloured panels will show signs of high temp levels long before the cylin

  3. Can I use other tools in my Pyroclassic fire chamber? 13/12/2018

    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.

  4. Do I need to grease the doorknob spindle? 13/12/2018

    A small amount of graphite grease should be applied sparingly and only occasionally to the spindle of the doorknob, twice a year is usually sufficient.

    Ashes from the fire have a gritty texture and over time this can cause wear on the doorknob spindle. Use a tiny amount of grease to lubricate the groove in the first thread of the spindle which can be applied with a matchstick or cocktail stick.

    Please note: only a small amount is needed, if too much is used it will melt and dribble down causing an unsightly stain, be sure to remove any excess before relighting the unit.

  5. When and how should I clean the flue? 13/12/2018

    Pyroclassic Fires are renowned for burning very cleanly when dry fuel is used but you should still always clean your flue once a year. This is often a requirement for many insurance companies.

    Keeping your flue pipes clean will help eliminate the risk of a flue fire. Your flue is also a great indication of how your wood fuel is performing. If the pipes are clean then the wood is good, if the pipes are filling up with carbon, creosote and tar deposits then you may need to revisit the operating instructions and refresh yourself with how to create a cleaner burning fire.

    The easiest way to clean the flue is by placing a deep baking tray or similar under the base of the flue and sweep the flue down into this, this stops all the debris from falling into the top chamber and requiring vacuuming out. Sweeping the flue into the top chamber is never a good idea as it can restrict the flow of gasses from the primary fire chamber and cause your fire to perform poorly.

    To clean the top chamber and wetback, you will need to remove the top plate (it just lifts off) and clean out the top chamber of soot and creosote. Take care not to remove any of the Kaowool lining during cleaning and ensure that the gasket is all intact before replacing the top plate. Support the flue with a frame made of wood so you can easily remove the top plate.

    The build-up around the wetback is best removed by hand. The wetback can be knocked out of alignment if it is moved when the creosote is being cleaned off so be careful as this can cause the constant rise to be knocked out of alignment and can result in water hammer developing in the system.

  6. What if I have a two storey house and require extra flue lengths? 13/12/2018

    A longer flue is fine however this will cause the fire to run at a slightly higher burn rate and consume more fuel than usual due to the extra draw that this length puts on the fire, otherwise there is no issue with this.

  7. Why is my door knob charred? 13/12/2018

    This will naturally happen slowly over years of use. However, this process can be accelerated by burning with the Turboslide open continuously and having the fire right up the front near the door. Please read our operating instructions again so you can use the Pyroclassic® IV correctly.

    If you need a replacement doorknob, you can purchase one from our Parts Shop. 

  8. How often do I need to clean out the ash? 13/12/2018

    The chamber in the Pyroclassic IV can operate with or without ash in it. However, it is preferential to empty this out every week or when the ash builds up to the extent that it could inhibit the operation of the Turboslide.

  9. Why is my Pyroclassic using more wood than I thought it would? 13/12/2018

    This could be because the loading door is not airtight. Check the gasket - if you need a replacement, you can purchase one from our Parts Shop.

    Another common cause of this is incorrect operation. Remember the Pyroclassic IV's significant heat storage capacity. Add logs less often and burn fuel further back in the fire chamber.

    Lastly, this can happen if the Turboslide is being left open for long periods. If this is the case, download our Operating Instructions and read about how to use it correctly. 

  10. Where does the wood burner standard apply? 13/12/2018

    Everywhere in New Zealand on properties of less than two hectares.
