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.

WATER HEATING
Water heating is by low pressure thermosyphon, maximum operating pressure 10 Bar.
The capacity of the wetback is 0.5 litres.
Excess heat from the wetback boiler to the domestic hot tank should be dissipated using a ‘heat leak’ radiator. A
drain-cock must be fitted in the lowest part of the system. See Hotflow wetback installation instructions
included with the wetback for more information. A copy of these instructions can be downloaded from
www.pyroclassic.co.nz.
Minimum safe distances from unprotected combustible materials:
Back - 350mm, Side - 480mm (See technical specifications sheet on protection measures).
This appliance is not suitable for use in a shared flue system and should not be operated in a room
with another combustion heater.
WARNING: There must not be an extractor fan in the same room or space as the appliance as it may
cause the stove to emit fumes into the room.

Ensure the door spindle lines up with the hole in the front plate when the door closes and that it is
lubricated with grease.
Inspect the air tubes and load limiter assembly to ensure there are no cracks/holes that have appeared.
If so, depending on the amount of wear, consider getting replacement air tubes installed.
Remove the front panel and ensure the two primary air inlets are clear.
Make sure the turboslide is sealing flush against the front plate of the fire by looking down the side of
the decorative panel.
