can cause metal parts to expand, buckle and crack. If
you are not certain, have a certified chimney sweep disas-
semble all parts so they can be inspected and cleaned.
5. Do not use salt or water on the fire in the cooking appli-
ance. Salt is corrosive and water will cause a dangerous
steam explosion. You might be able to control the fire by
using ashes, sand or baking soda, since baking soda is an
ingredient used for dry chemical fire extinguishers.
6. After a chimney fire, when it is safe to do so, check inter-
nal locations such as an attic and under the roof and keep
watching for two or three hours. There may be delayed
smoldering and subsequent ignition, even if the fire inside
the chimney has been controlled.
TO REDUCE THE RISK OF A CHIMNEY FIRE:
1. Keep chimney and grease fan clean.
2. Always turn ON fan when using the cooking appliance.
3. Do not leave cooking appliance unattended when in use.

3. MECHANICAL INSTALLATION
3.1 POSITIONING
In accordance with NFPA 96, roof mounted fans shall have
their discharge outlet at least 40 inches above the roof
surface.
3.2 INSTALLATION ON STEEL DUCT
• Insert the adapter (FR) into the grease duct, where the
long collar engagement ensures safe anchoring (See
Fig. 2). If necessary, the adapter can be secured by means
of long self-tapping stainless steel screws into the side
of the collar through the chimney wall. Do not obstruct the
grease flow.
• Place the neoprene gasket (sold separately) on top of the
adapter.
Remove the transport securing device (if present) holding
the motor shaft and impeller in place.
• Place the fan on the adapter with the fan inlet centered
over the chimney outlet.
• Open the fan and secure the fan onto the adapter, through
the pre-drilled holes in the bottom, with
lag bolts or self-tapping sheet metal screws, one at each
corner.
• Check the gasket to insure that it forms a complete seal.

3.3 INSTALLATION ON ROOF CURB
• If the fan is supplied with a curb cap, secure the cap to the
roof curb with self-tapping sheet metal screws (see Fig. 3).
• Place the neoprene gasket on the top of the curb cap
with the hole centered over the curb cap opening (sold
separately).
• Remove the transport securing device (if present) holding
the motor shaft and impeller in place.
• Place the fan on the neoprene gasket centered over the
cutout.
• Open the fan and secure the fan onto the roof curb,
through the pre-drilled holes in the bottom, with lag bolts
or self-tapping sheet metal screws, one at each corner.
• Check the gasket to insure that it forms a complete seal.

3001391 12.16
3.4 TERMINATION OF VENTING SYSTEM
In order to achieve optimal performance and energy
consumption for the RS Fan or GSV Fan, the duct must be
installed as shown below and the distances observed. From
the last elbow to the termination point the distance has to
be 3 times the diameter of the flue. For example if you using
12in flue (12 X 3 = 36in). So the distance from the last elbow
to the fan termination point should be 36 inches.
3.5 INSTALLATION ON SIDE WALL
• Make sure the vent terminates flush with the wall. Insert
the steel chimney adapter and secure it safely to the wall.
Seal around the edges of the adapter flange.
• Mark the locations of the wall anchors and predrill holes
for them.
• Turn the fan upside-down and lay a bead of hi-temp
silicone on the base close to the outer edge (not shown).
• Open the fan and secure the fan onto the adapter with
wall anchors, through the pre drilled holes in the bottom.
Make sure the conduit is located on one of the sides.
Never on the upside or downside.
• Seal around the fan base to make sure it is watertight and
no water can slip in between the fan and the adapter. Do
not block the 4 drain holes.
3.6 HIGH TEMPERATURE APPLICATIONS
• If the fan is used for applications that exceed its
temperature rating, dilution bolts must be used.
• Install the dilution bolts in the outer holes of the fan base.
• Adjust the height of the dilution gap by adjusting the
dilution bolts, so the temperature of the exhaust going
through the fan does not exceed the fan’s temperature
rating.
• Be aware the dilution bolts will have a negative impact on
the fan’s actual capacity and a stronger fan model may
be required. For more information, please refer to the
installation manual accompanying the dilution bolts.
