For multi air heater installations the following minimum distances between units must be observed
Between units, side to side/back to back
M
3.0
Note: All models must not be installed at a
height of less than 2.5m to the base of the
unit.
Note: For LNVx D units the normal air flow
direction is from right to left when viewing the
heater from the burner/controls end with the
fan unit upstream.
Note: The minimum clearances must be
observed for installation and servicing.
Warning: Any combustible material adjacent
to the air heater and the flue system must
be so placed or shielded as to ensure that its
temperature does not exceed 65 °C.
Warning: When LNVx modular components
are used in conjunction with the heater each
component must be individually supported.
Note: The access door to the controls section
may be removed to improve access. Open the
door to 90°, remove the earth cable at the
bottom, and then lift the door vertically
upwards to disengage the hinge plates. Refit in reverse
order. Ensure that the earth cable is refitted.
The air heater may be installed either:
a) suspended from suitable vertical drop rods
(recommended maximum length is 1.8m).
b) on specifically designed cantilever brackets from a non
combustible wall.
c) on a level noncombustible surface. The surface must
not extend past the front edge of LNVx F heaters.
The method of installation must be capable of adequately
supporting the weight of the unit (See section 1.2) and
any ancillary equipment. Before installing the heater
the existing structure must be inspected to ensure it is
suitable. All supports should be protected against the
effects of rust or corrosion.
Raise the heater up to the point of installation using
suitable and safe means and connect to the means of
suspension.
Note: Each heater is provided with additional
central suspension points (suspension points
running along the front and back are for
permanent connection, suspension points
running left to right in the centre are for temporary
support) that can be used to provide temporary support,
using suitable means, whilst the unit is being installed.
Under no circumstances must these points be used as the
final means of suspension.
