Hercules Boiler Model 15
Permanent air vent
The stove requires a permanent and adequate air supply in order for it to operate
safely and efficiently. In accordance with current Building Regulations the installer
should have fitted a permanent air supply vent into the room in which the stove is
installed to provide combustion air. This air vent should not under any circumstances
be shut off or sealed.
Recommended Fuels
This appliance has obtained CE approval for burning the following fuels –
Manufactured and natural smokeless fuels, and wood logs only.
The Hercules range have been CE certified burning Manufactured and
natural smokeless fuels, and wood logs not exceeding 35cms in length.
Approval does not cover the use of other fuels either alone or mixed with
the suitable fuels listed above, nor does it cover instructions for the use of
other fuels.
Although CE certification covers the use of the smokeless fuels listed, the
claimed rated output, has been obtained burning a single representative
smokeless fuel, under standard test conditions. However, in the home, a
variety of operating conditions can occur and the performance of the
appliance may vary to some degree with these conditions and different
fuels may need to be burnt at different rates to provide the same heat
output.
The recommended fuels are Wood logs no longer than 35cms (dry, seasoned
for a minimum of one year) and solid mineral fuels (e.g. Natural smokeless
fuels) The larger briquettes are recommended as they concentrate less
heat in one spot reducing the likelihood of damage to the grate. Please find
a recommended and non recommended list below.
