1. Product Information
1.1 Function
Description The EXHAUSTO model EFH Exhaust Fan is designed to provide exhaust in multi-story buildings. The fan assures
that a neutral or negative pressure is maintained in the entire duct system.
This product is designed to prevent draft problems from occurring by creating mechanical draft in venting
  systemsandtherebyincreasingthecapacityandefciencyofaventingsystem.
The fan discharges horizontally at a high velocity. The top of the fan housing can be opened for easy service
and access to duct. The fan must be mounted at the duct termination, in the vertical position. The fan is typically
mounted on a roof curb and cap.
Use The EXHAUSTO EFH fan is designed to provide exhaust to kitchens, bathrooms, and other building exhaust
applications where the duct temperature does not exceed 175oF.
Code Installations must conform to requirements of the authority having jurisdiction. Where required by the authority
having jurisdiction, the installation must also conform to the Standard for Draft Equipment and The National
Fuel Gas Code, ANSI Z223.1/NFPA 54.
All electrical wiring must be in accordance with the requirements of authority having jurisdiction or, in the absence
of such requirements, with the National Electrical Code, NFPA70.
EXHAUSTO Model EFH meets the requirements of UL Standard 705, Standard for Power Ventilators. The fan is
  manufacturedatanISO9001certiedplantandbearstheEuropeanCEcompliancelabel.
1.2 Shipping
The packing list (attached to one of the packages) lists all items in the shipment and each package has a
label showing the contents. Check the list against all materials on the job site before installation.

3. Mechanical Installation
Generally, a mechanical venting system must be installed a minimum of 3 feet away from any forced air inlet located within
10 feet and a minimum of 4 feet away from any door or window. For complete infromation, consult EXHAUSTO or the
local building codes.
This fan is for vertical installation only. DO NOT side-wall vent this fan.
3.1 Installing a Single Fan on a Roof Curb
The EFH fan should be mounted on a roof curb and curb cap. Before Installing the fan, verify the roof curb is properly
attached and sealed to the roof. Place the curb cap on top of the roof curb. Roof curb and curb cap are supplied
separately by EXHAUSTO.
Cut a hole in the silicone gasket to correspond to the hole in the curb cap. The hole should be sized so there is least
3/4” between it and any edge of the silicone gasket.
Place the silicone mat on the curb cap.
Place the fan on the silicone gasket. Apply high temperature silicone around all edges of the gasket to prevent water
from leaking into the curb and/or duct.
Attach the fan base to the curb cap with long sheet metal screws. The screws should be long enough to clear the fan
base, silicone gasket and curb cap. Seal bolt heads with silicone.

4. Electrical Installation
4.1 General
Danger: Turn off electrical power before servicing. Contact with live electric components can cause
shock or death.
All electrical wiring must be in accordance with requirements of authority having jurisdiction or, in absence of such
requirements, with National Electrical Code NFPA 70 — latest edition. If an external electrical source is utilized,
system must be electrically grounded in accordance with requirements of the authority having jurisdiction or, in the
absence of such requirements, with the National Electrical Code NFPA 70 — latest edition.
Power requirements for the system depends on the fan size. Electrical requirements are:
EFH 200 1 x 120 V / 60 Hz 1.4 Amps
EFH 250 1 x 120 V / 60 Hz 2.9 Amps
EFH 315 1 x 120 V / 60 Hz 5.8 Amps
Theexhaustfanshaveasplitcapacitormotorwithinnitelyvariablespeed.
The fan speed control supplied is rated 1x120V/60 Hz and 5 Amps. It has an adjustable low voltage set point of min.
65 V +/- 5 V.
Notice: If any of the original wire supplied with the system must be replaced, use similar wire of the
same temperature rating. Otherwise, insulation may melt or degrade, exposing bare wire.
4.2 Single Fan with Fan Speed Control
The wiring diagram shown in Fig. 3 shows the connection of the fan to a fan speed control. Use 2-conductor wire,
 minimum14AWGwhenconnectingthefan.Allwiringmustberunoutsidethechimneyorstackinexibleorrigid
metal conduit.

4.4 Single Fan with MEC 18
The wiring diagram shown in Fig. 4 shows the connection of the fan to a MEC 18 Control. Use 2-conductor
wire, minimum 14 AWG, when connecting the fan to the control. All wiring must run outside the chimney
  orstackinexibleorrigidmetalconduit.TheMEC18Controlisforindoorinstallationsonly.SeetheMEC

5.Start-UpandConguration
5.1 System Testing
Before any adjustments are made to the system, follow these procedures:
1. Turn the chimney fan ON and make sure that it is running. Increase and decrease the speed of the fan by
adjusting the fan speed control to make sure it is operating properly.
2. Turn the fan OFF and make sure the pressure switch opens, so the power to the circuit it controls, is
disconnected.
Make sure the fan is running in the correct direction; the fact that the fan blows is no guarantee it is
doing so. Running the fan in the wrong direction over a longer period of time will damage the motor.
Danger:Checkotherheatingappliances(waterheater,furnace,replaceetc.)forproperoperation
whilethechimneyfanisoperating.Makesurenouegasesarespillingoutasthiscanleadto
carbon monoxide poisoning.
5.2 Adjusting the Fan Speed
Start up all appliances. Use the fan speed control to set the speed of the chimney fan so no back pressure is
 experiencedanywhereinthesystem.Checkthesystemforuegasspillage.Markthissettingonthefanspeed 
control cover.
If a MEC 18 Control is used, remove the cover and adjust the fan speed using the potentiometer dial on the display
board of the control. See the MEC 18 Installation Manual for further instructions.

6. Maintenance & Troubleshooting
6.1 Care and Cleaning
Warning: Disconnect all power before servicing the fan.
The EXHAUSTO EFH Fan is designed for prolonged use. The impeller should be inspected three months after the
inital installation and periodic inspections should take place based on the condition of the fan at that time (a minimum of
once a year). Clean the housing and impeller as required. Do not get water on the motor.
The top of the fan is hinged and can be opened in order to ease the cleaning.
The fan motor is equipped with permanently lubricated and sealed ball bearings. No maintenance is required.
