Checking the usage

LFC
Linear flow control to adjust volumes of gas and cold
air on various appliances. With mounted actuator
IC 20 or IC 40, the LFC is suitable for regulating flow
rates for control ratios up to 25:1 in modulating or
stage-controlled combustion processes.
This function is only guaranteed when used within the
specified limits – see also Technical data. Any other
use is considered as non-compliant.

Installation

CAUTION
Please observe the following to ensure that the LFC
is not damaged during the installation:
– Sealing material, cuttings and other impurities
must not be allowed to get into the housing.
– The installation location must be dry. Do not
install the unit in the open air.
– Use approved sealing material only.
– Install the LFC in the pipe free of mechanical
stress.
– Do not clamp the unit in a vice or use it as a lever.
Only secure the flange by holding the octagon
with a suitable spanner. Risk of external leak-
age.
– Installation of IC 20, IC 40 in the vertical or hori-
zontal position, never upside down.
– Max. inlet pressure p

Linear flow control LFC and actuator IC are supplied
separately:
▷
The LFC and IC can be assembled before or after
the LFC has been installed in the pipework.
▷
The fastening set for the assembly of LFC and IC
is supplied separately – see Accessories.
1 Install a filter upstream of the LFC, in order to
protect it against impurities in the pipe.
▷
The IC may be installed offset by 180°.
