Installation
The infrared lamps heat by direct radiation rather than by heating the air in
the room. So the Instant Heat 2 ducted should be located directly over the
drying area. HPM Instant Heat 2 ducted must not be installed where there is a
possibility of water splashing on to the lamps. Locate in accordance with the
requirements of Wiring Rules AS/NZS 3000 relating to damp situations. This
means that no part of the Instant Heat 2 may be located directly above any part
of the bath or shower recess or enclosure. For unenclosed showers refer to
Wiring Rules conditions.
Note: Steam will only be removed if there is sufficient flow of air through the room.
Ensure adequate inlets exist through windows, vents or under the door. Air-flow
path from inlets to fan should ideally pass over the steam sources. See over – ‘Getting
the most from your Instant Heat 2 Ducted’. Regulations concerning the discharge of
air have to be fulfilled. The Instant Heat has a free air discharge of 93m³/hr and care
should be taken that air flow throughout meets specific requirements in building
regulations. Local building codes may require venting to the outside. Ducting can
be fitted and vented to the outside using exterior grille provided as shown in Fig.1
and Fig.2. Vertical ducting with roof vents will result in reduced fan performance,
increased noise and condensation/dripping.

Location
The Instant Heat is for ceiling mounting only, with
the lowest point to be at least 2.2 metres above floor
level. It is not intended to be installed in wardrobes
or within 300mm of sides of walls, as per Figure 3.
There is a danger of combustion if placed too close
to curtains or other flammable materials.
Additional Instant Heats may only be installed if at
least 1.2m clearance between them is observed.
Fig.3
Instant Heat 2 may be installed in the ceiling cavity
between joists using the built-in clip fasteners.
Correct installation requires the cavity to have a
minimum height of 220mm for safe operation. The
clearances between Instant Heat and surrounding
joists and above ceiling shown in Fig.4 and Fig.5
shall be observed. Thermal insulation or similar
material shall not be placed on top of the Instant
Heat, and adjacent material to the side shall be
kept clear to a minimum distance of 300mm.
Joists, beams and rafters shall not be cut or
notched to install the Instant Heat.
After determining the location of the Instant Heat
2 Ducted use the template to mark out and cut an
opening 330mm x 170mm. If adequate support is not
available for the instant heat, it may be necessary to
provide extra strengthening.
