Pyroclassic Fires Operating Instructions | Updated May 2019 | V4 | 8
LIGHTING YOUR FIRST FIRE
Do not be alarmed if your fire does not perform to your expectations the first time it is lit from new. It can take several
fires to fully cure the ceramic cylinder and build up an ash bed before full performance can be achieved. You may even
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 fumes are released as the special heat-
resistant paint cures. This will not last long and should not happen again.
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 scrape 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
http://www.pyroclassic.co.nz/resources/videos/
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 and establishing the fire and for igniting a new fuel load.
High flue draw: investigate cause and consider an H type cowl if consumption is excessive.
