GENERAL SAFETY INFORMATION
When using electrical appliances, basic precautions should
always be followed to reduce the risk of fire, electric shock and
injury to person, including the following:
WARNING:TO REDUCE THE RISK
OF FIRE, ELECTRIC SHOCK AND INJURY TO
PERSON, OBSERVE THE FOLLOWING:
a) Use this unit only in the manner intended by the manufacturer. If you

b) Before servicing or cleaning the unit, switch power off at service
panel and lock the service disconnecting means to prevent power
from being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
WARNING:TO REDUCE THE RISK
OF FIRE, ELECTRIC SHOCK AND INJURY TO
PERSON, OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-related construction.
b) Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment manufacturer’s guideline
and safety standards such as those published by the National Fire
Protection Association (NFPA) and the American Society for Heating,
Refrigeration, and Air Conditioning Engineers (ASHRAE), and the local
code authorities.
c) When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.

e) To avoid motor bearing damage and noisy and/or unbalanced impellers,
keep drywall spray, construction dust, etc. off power unit.
f) Read all instructions before installing or using exhaust fan.
g) For residential installations only.
h) Must use suitable weather hood with insect screen to protect air intake.
WARNING:TO REDUCE THE RISK OF
FIRE, ELECTRIC SHOCK, DO NOT USE THIS FAN

WARNING:THIS UNIT IS DESIGNED AND
TESTED TO BE A SUPPLEMENTAL HEATER. IT IS NOT
INTENDED TO BE USED AS THE PRIMARY SOURCE OF
HEAT.
WARNING: THE DUCTING FROM THIS FAN HAS A
STRONG EFFECT ON THE AIR FLOW, NOISE AND ENERGY USE OF THE
FAN. USE THE SHORTEST, STRAIGHTEST DUCT ROUTING POSSIBLE
FOR BEST PERFORMANCE, AND AVOID INSTALLING THE FAN WITH
SMALLER DUCTS THAN RECOMMENDED. INSULATION AROUND THE
DUCTS CAN REDUCE ENERGY LOSS AND INHIBIT MOLD GROWTH.

INSTALLATION INSTRUCTIONS
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION MAKE SURE THE MAIN UNIT IS INSTALLED ACCORDING
TO ALL INSTRUCTIONS INCLUDED WITH THE UNIT.
1. Remove the 4 screws holding the
duct collar and gasket in place on the
main unit. Save all these screws, the
duct collar and gasket (Figure 1).
2. Install the duct collar and gasket you
just removed onto the heater unit
panel using the screws removed in
Step 1.
3. Remove the three screws holding the
top of the main unit in place. Save
these screws (Figure 2).
4. Remove the electrical knockout on
the front of the main unit using a
straight-blade screw driver
(Figure 3).
5. From inside the main unit, remove
the foam insert covering the knockout
area and discard.
6. Install the included plastic bushing
into the knockout hole to protect the
wires (Figure 4).
7. Feed the heating unit’s electrical
connector through the knockout hole
and connect to the 4 pin connecter from the control inside the main unit (Figure 4).
8. Connect the heater unit to the main unit using the 6 screws provided. There are two
screws on each side of the main unit (Figure 5).

9. Reinstall the main unit top cover using the three screws removed in Step 3 (Figure 6).
Ducting
NOTE: If additional ducting will be connected to the unit, 6" or larger rigid duct is
recommended for best performance. At the base of the duct adapter, there is a small diameter
test port hole covered with a plastic cap. Make sure the test port is not covered up with the
ducting so that it can be accessed for pitot tube testing. To access the port, remove the port
cover and insert tube.
Usage and Controls
This heater unit is for use in climates that the air coming into the unit falls below 54°F. The
display will show a thermometer icon with either a “1” or “1 2” when the temperature range is
at a level where the heating element would come on if present. Stage 1 - “1” turns on when the
intake air temperature is between 39°F and 54°F. Stage 1 and 2 “1 2” turn on when the intake
air temperature is between 33°F and 39°F.
Maintenance
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE SERVICING THE UNIT.
Clean the unit by wiping all parts with a dry cloth or gently vacuum the fan. NEVER IMMERSE
ELECTRICAL PARTS IN WATER. See instructions included with the main unit for additional
care and usage items.
NOTE: The heater function is equipped with an energy saving fan off time delay. When the
heater function is turned off the heating element will turn off but the blower will continue to
run for an additional 30 seconds delivering any residual heat to the occupied space.
