SECTION 4: VENTILATION
The 400 and 600 models do not normally require purpose provided ventilation.
The 1000 model
does
require purpose made ventilation to an outside area in accordance with
current regulations.
However, if a second appliance operating within the same room or space must be taken into
consideration when assessing ventilation.
When commissioning the appliance spillage is detected, then amongst other problems there
may be insufficient natural ventilation for correct operation of the flue.
If spillage is detected with windows closed, but the appliance does not spill with the windows
open, this demonstrates a lack of natural ventilation.
If spillage is still detected with the windows open, the flue is at fault.
Installation of an air brick is the best solution to lack of ventilation.
Any ventilation fitted must comply with BS 5871 part 2 and BS 5440 part 2.
Air Vents fitted under or within the immediate vicinity of the appliance must not be used as
adverse effects to the operation of the Flame Safety Device (FSD) may occur.
Spillage detected during commissioning is almost always a result of poor flue performance
that cannot be corrected by any amount of ventilation
.
For Republic of Ireland ventilation may be required, see IS 813, ICP3, IS
327, and any other rules in force.
Section 5: SITE REQUIREMENTS
The fireplace opening should be inspected and repairs made where necessary.
This appliance requires a natural draught flue system which may be one of the following;
225mm x 225mm (9in x 9in) brick or stone (ALL MODELS WILL FIT)
175mm (7”) Minimum diameter lined flue (ALL MODELS WILL FIT)
125mm (5”) minimum diameter lined brick or stone. (400 AND 600 MODELS ONLY)
125mm (5”) minimum diameter twin wall flue conforming to BS 715, (400 AND 600 MODELS
ONLY)
175mm (7”) minimum diameter twin wall flue conforming to BS 715, (ALL MODELS WILL FIT)
Any existing draught device situated under the fireplace must be sealed off.
The opening area must be non-combustible.
It is recommended that a tactile barrier should be place on the floor in front of the appliance
to stop the elderly, infirm or Children from direct contact with the hot surfaces of the
appliance.
The area immediately above the outlet must form a smooth path into the flue.
