3.4.4 Air delivery connections
The CVO Series
warm
air heater manufactured by BENSON HEATING has been designed to diffuse
warm
air
directly or distribute it through a system of ducts.
Direct diffusion
This type of installation is carried out where the heater is used to heat the room/zone in which it is installed. In
this event diffusion gratings, which can be oriented as desired, are supplied.
Diffusion through ducts
This type of installation is carried out where the hot air needs to be distributed through ducts to several rooms or
into a room other than that where the heater is actually installed.
The ducts must be sized so that the overall
resistance opposed by the circuit does not exceed the available static pressure value given in paragraph
2.2
.
The delivery duct is fixed to the relevant aperture using self-tapping screws; an appropriate seal should be
interposed (see the dimensions indicated in paragraph 2.2).
fig. 3.4.4.1 Air delivery/return duct connection
If the
warm
air heater is installed in a separate room (e.g. closet, stairwell, basement etc.) this room MUST have
adequate ventilation or open out towards the rooms/zones to be heated otherwise the air intake will reduce the
air pressure in the room itself and cause serious inconveniences.
In this case it is advisable to connect the heater air intake compartment directly to the rooms being heated by
way of a duct (as illustrated in the diagram).
When this solution is adopted place a grating with detachable door on the duct itself so as to allow extraction of
the filtration cell. You will also need the special panel to close the burner compartment.
