Installation types
The flue gas exhaust/combustion air intake of the
Calorio M gas-fired convectors can be realised in one of
the following ways:
▶
With coaxial pipes with outlet on the installation
wall (maximum pipe length: 1 metre) (see Figure
3.2
p. 13).
▶
With coaxial pipes with 90° outlet (max pipe length: 1
metre) (see Figure 3.3
p. 14). In this case, it is neces-
sary to use the 90° casing for coaxial pipes, available as
OCFF004 optional.
▶
With separate pipes (see Figure 3.4
p. 14) . In this
case, it is necessary to use the separate exhaust casing
available as OCFF002 optional.
Warnings
The installation of pipes with a vertical downward
outlet is prohibited (leads to recirculation of flue
gas with lock-out of the appliance).
It is forbidden to install coaxial pipes with a vertical
outlet upwards (due to rain, water, objects infiltra-
tion with consequent lock out of the appliance).
