Before Installation - Nordpeis N-24 round Installation & User Manual

1. Before installation

Make sure the chimney is in good working order and that the required chimney draft of between 14
– 25 Pascal negative is obtained. A minimum chimney height of 4meters is required. The chimney
must be Class I – suitable for use with wood. Please ensure the chimney is swept prior to installing
the appliance. The chimney is the key to successful installation and operation of the appliance. If the
chimney is in poor condition or of the wrong design or construction the performance will be adversely
effected and problems will be experienced with combustion and possible smoke emission into the
room. The chimney should be one of the following types:-
• Brick built with suitable liner for use with wood / solid fuel appliances
• Twin wall stainless steel approved for use with both wood / solid fuel appliances
• Prefabricated "concrete" type systems approved for use with wood / sold fuel
appliances
DO NOT USE FLEXIBLE LINERS DESIGNED FOR USE ONLY WITH GAS APPLIANCES
NEVER ALLOW THE APPLIANCE TO CARRY THE WEIGHT OF THE CHIMNEY
You must ensure that there is sufficient fresh air supply within the room as per Building Regulations. If
insufficient fresh air is provided this will lower the atmospheric pressure within the room and may lead
to poor combustion and smoke leakage from the appliance. We recommend that a minimum airbrick
of 33cm² is installed (54cm² for installations with flue draft stabilisers).
The fireplace should stand on a fireproof hearth suitably constructed from materials which are able to
support the weight of the appliance and the flue system. The hearth needs to be 300mm to the front
of the appliance and 150mm to each side of the fireplace and must conform to current Building Regu-
lations. You must ensure that the hearth can not be inadvertently be covered by carpet, rugs etc – this
can be done by adding a kerb etc.
The following clearances around the fireplace must be observed to allow the correct operating proce-
dure:-
75mm either side of the fireplace
200mm above the fireplace to non-combustible material
380mm above the fireplace to combustible material
We have on page 19 placed a check form you can use to prove correct installation of your new fire-
place.
