OPTIONAL FIRE / BALANCING DAMPER GBD SERIES
Gaylord System Balancing (GBD)
The XG Series Ventilator will optionally come with a Gaylord
Industries Listed balancing damper. The options available are the
GBD-IS (balancing only damper), and the GFBD (Fire Balancing
damper). The GBD-IS is set from below and performs the task
of raising or lowering the exhaust airflow to any section that it is
installed on. The GFBD is a fire / balancing damper that will close
upon detection of any internal fire burning inside the plenum. The
thermostat for the XG series Ventilator is set to 325°F, and must
be factory installed. The balancing of the GFBD is done by way of
a potentiometer found in the UV electrical chase,
(see Figure 19)
or in the thermostat chase shown in Figures 4 & 8. The GFBD is
intended to close upon the deactivation of the exhaust fan every
night. The feature is intended to eliminate cool air from drafting
down the exhaust ducts, and entering the kitchen.
Both the GFBD,
(shown in Figure 14)
, and the GBD are not advised
for use over solid fuel applications, and should be inspected at least
semi annually with the rest of the exhaust system.
For further details on the Gaylord Industries commercial kitchen
exhaust dampers, please consult the GBD technical manual.

GBD “DSD” Damper Set Dimension
The adjustment of both systems relies on the internal dimension between
the two blades. Called the “DSD”. The manipulation of that distance will
accomplish your air balancing needs. See Figure 15, above, the GBD
Technical Manual, and “Measuring Airflow” in this manual for more
details.
