Hercules Boiler Model 14
The tertiary air control
The tertiary air control, or afterburner control, is used to burn the smoky fumes and
volatile gasses that would normally be lost up the chimney. Because of the lack of
oxygen within these gasses, they would not burn any more. When the tertiary air
control is used, additional heat will be generated. Using this control helps prevent
excessive creosote formation and smoke pollution, it also makes the fire burn at a
more efficient rate as extra heat is generated when using this control.

Curing the Stove
Before lighting the stove check with the installer that the installation work and
commissioning checks described in the installation instructions have been carried out
correctly and that the chimney has been swept clean, is sound and free from any
obstructions. This curing process may have been undertaken by your installer as part
of the stoves’ commissioning and handover and the installer should have shown you
how to operate the stove correctly.
Your stove is made of a number of cast iron components and we recommended that
the first burn should be a small fire for about 30 minutes. This enables the stresses
and strains at the joints to be taken up and settle gradually. The second burn can be
a larger fire for an hour. During the curing process, the stove will give off a pungent
smell and some fumes. This is the paint curing and is quite normal. Provide
ventilation whilst this is happening since the fumes can be quite strong and may set
off smoke alarms in the room. The paint may become slightly lighter in colour when
the stove is cured, particularly in the hottest spots. Fire
Grate polish can be used to keep the stove in good condition, or stove spray paint
can be used to re-touch the stove. The correct stove spray can be obtained from
your stove stockist.
