5.1.4 Secondary air control
The control has an internal rotary plate with slots, housed inside the body of the appliance
and is located below the left hand corner of the fire door assembly, when looking at the
front of the appliance.
Sliding the control knob to the right, as far as it will go, achieves the fully open position, see
figure 3. Sliding it to the left will shut down / reduce the air as shown in figure 4.
NOTE : All Farringdon Eco models are fitted with a mechanical stop for smoke
control areas, please note that the secondary air control will not fully close, thus
allowing a bleed of air to the fire box to reduce smoke emissions.
5.1.5 Tertiary Air
All Farringdon Eco models have tertiary air supply that can be seen working during certain
conditions during the burning period. The outlet for the tertiary air, is at the rear of the fire
box chamber, just below the throat plate through a series of small holes (See page 6).
Tertiary air is employed, to provide additional air to the upper areas of the fire box to
promote additional burning of the unburnt combustion gases and thus ensuring a cleaner
burn emission.
There is no user adjustment required for the tertiary air, as the required air supply is factory
set during the production process.
