Outside Air Requirements; Floor Protector (Hearth) - Dimplex Nectre n65 Installation/Operation Instruction Manual

Installation
Check the practicability of installing the flue system in relation to any obstructing roof beams before
positioning the stove.
Depending on the type of flue used, the clearances to combustible surfaces varies.
WARNING: Do not install this stove in a bedroom.

Outside Air Requirements

The stove requires sufficient fresh air supply to operate. The performance of the stove may be
affected if there is insufficient fresh air for combustion. Modern energy-efficient homes are more
airtight compared to older homes. Airtightness makes a house more susceptible to negative pressure
when combusted air is exhausted through the chimney. Large extraction fans can cause extreme
negative pressure which can lead to air starvation, which negatively impacts the performance of the
stove.
To prevent air starvation, slightly open a nearby window to allow fresh air to enter the room. In
extremely cold regions, opening a window may not be feasible, or icing may block the required
ventilation. Installation of an outside air duct with a rodent screen and rain hood will be required to
overcome the issue of air starvation. Check with local building officials for specific requirements that
apply in certain localities.

Floor Protector (Hearth)

Unless the stove will be standing on a heat resistant floor such as concrete slab with slate or tiles, it
is necessary to provide a floor protector (hearth). The floor protector must be made of a continuous,
noncombustible material such as steel, ceramic tiled floor, cement board, brick, or any other
approved or listed material for floor protection. Materials corresponding to ASTM E136 and UL 763
are considered to be combustible materials, with the exception of gypsum.
Figure 2 shows the minimum size of the floor protector. Refer to the table below for minimum distance
between the edge of the floor protector and the curved front of the edge of the stove and from the
side curved edges and edge of the rear panel. For installations with horizontal rear connector, the
floor protection must extend under and 2" on either side of the connector.
