CG3 VENTILATOR DESCRIPTIONS
There are 5 different types of CG3 “Classic Gaylord”, water-
wash ventilators. The differences involve the type and location
of fire damper and whether the ventilator has a fire damper. The
first part of the model number indicates the type of ventilator,
see below:
Explanation of Prefixes:
CG3 ........... Water-wash ventilator with three-position,
thermostatically activated (electric) damper
at air inlet slot.[With Damper motor and 1
or more Thermostat(s)]
CG3-FDL ... Water-wash ventilator with three-position, ther-
mostatically activated (electric) damper at air
inlet slot. A bracket (Fire Damper Lockout)
has been added to prevent the damper from
closing to the fire position.[With Damper
motor and 1 or more Thermostat(s)]
CG3-FDD ... Inlet damper is fixed, and there is a weighted
fuse link activated fire damper located at the
duct collar. [No Damper motor, No Ther-
mostats]
CG3-FDT ... Inlet damper is fixed, and there is a weighted
fuse link activated fire damper located at the
duct collar, and there is a single thermostat
to activate the fire mode in the control cabinet
and ventilator. [No Belimo, One Thermo-
stat]
CG3-ND
Inlet damper is fixed. No Fire Damper at duct
collar. A bracket (Fire Damper Lockout) has
been added to show that the damper will not
close to the fire position. [No Damper
motor, No Thermostats]
Summary of CG3 Ventilators:
The CG3 and CG3-FDL are very similar. Both have a damper
motor that closes the inlet damper during the wash mode and
stays closed until the exhaust fan is started. Both have
thermostats that can detect an “Internal Fire”. The main
difference is the CG3-FDL has a Fire Damper Lockout (FDL)
bracket added that prevents the inlet damper from closing to
the fire position, so it does NOT have a fire damper.
The CG3-FDD and CG3-FDT are similar to each other. Both
have fixed inlet dampers and do not have damper motors. They
both have fuse link activated fire dampers in the duct collar that
will close when the temperature reaches 250°F. The CG3-FDT
has an added thermostat that will detect an “Internal Fire” and
activate the “Internal Fire Mode”. The CG3-FDD does NOT
have any thermostats.
The CG3-ND has a fixed inlet damper and does NOT have a
fire damper.
