SECTION II: SAFETY
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which, if not
avoided may result in minor or moderate injury. It is also used to
alert against unsafe practices and hazards involving only property dam-
age.
Improper installation may create a condition where the operation of
the product could cause personal injury or property damage.
Improper installation, adjustment, alteration, service or mainte-
nance can cause injury or property damage. Refer to this manual
for assistance or for additional information, consult a qualified con-
tractor, installer or service agency.
This product must be installed in strict compliance with the installa-
tion instructions and any applicable local, state, and national codes
including, but not limited to building, electrical, and mechanical
codes.
FIRE OR ELECTRICAL HAZARD
Failure to follow the safety warnings exactly could result in serious
injury, death or property damage.
A fire or electrical hazard may result causing property damage, per-
sonal injury or loss of life.
1. Install this electric furnace only in a location and position as speci-
fied in SECTION III of these instructions.
2. Always install the electric furnace to operate within the electric fur-
nace's intended maximum outlet air temperature. Only connect the
air handler to a duct system which has an external static pressure
within the allowable range, as specified on the EB rating plate.
3. When an electric furnace is installed so that supply ducts carry air
circulated by the air handler to areas outside the space containing
the air handler, the return air shall also be handled by duct(s)
sealed to the air handler casing and terminating outside the space
containing the air handler.
4. The electric furnace is not to be used for temporary heating of
buildings or structures under construction.
5. The size of the unit should be based on an acceptable heat loss or
gain calculation for the structure. ACCA, Manual J or other
approved methods may be used.
SAFETY REQUIREMENTS
1. This electric furnace should be installed in accordance with all
national and local building/safety codes and requirements, local
plumbing or wastewater codes, and other applicable codes.
2. Refer to the unit rating plate for the EB model number, and then
see the dimensions page of this instruction for supply air plenum
dimensions in Figure 3. The plenum must be installed according to
the instructions.
2
3. Provide clearances from combustible materials as listed under
Clearances to Combustibles.
4. Provide clearances for servicing ensuring that service access is
allowed for electric furnace elements and blower.
5. Failure to carefully read and follow all instructions in this manual
can result in electric furnace malfunction, death, personal injury
and/or property damage.
6. Check the rating plate and power supply to be sure that the electri-
cal characteristics match.
7. Electric furnace shall be installed so the electrical components are
protected from water.
8. Installing and servicing heating/cooling equipment can be hazard-
ous due to the electrical components. Only trained and qualified
personnel should install, repair, or service heating/cooling equip-
ment. Untrained service personnel can perform basic maintenance
functions such as cleaning and replacing the air filters. When
working on heating/cooling equipment, observe precautions in the
manuals and on the labels attached to the unit and other safety
precautions that may apply.
9. These instructions cover minimum requirements and conform to
existing national standards and safety codes. In some instances
these instructions exceed certain local codes and ordinances,
especially those who have not kept up with changing residential
and non-HUD modular home construction practices. These
instructions are required as a minimum for a safe installation.
INSPECTION
As soon as a unit is received, it should be inspected for possible dam-
age during transit. If damage is evident, the extent of the damage
should be noted on the carrier's freight bill. A separate request for
inspection by the carrier's agent should be made in writing. Also, before
installation the unit should be checked for screws or bolts, which may
have loosened in transit. There are no shipping or spacer brackets
which need to be removed.
Also check to be sure all accessories such as heater kits, suspension
kits, and coils are available. Installation of these accessories or field
conversion of the unit should be accomplished before setting the unit in
place or connecting any wiring, electric heat, ducts or piping.
CODES
The electric furnace must be installed in accordance with the following
codes:
• Standard for the Installation of Air Conditioning and Ventilating
Systems (NFPA 90A)
• Standard for the Installation of Warm Air Heating and Air Condi-
tioning Systems (NFPA 90B)
• National Electric Code (NFPA 70)
• Canadian Electrical Code, Part I (CSA C22.1)
• All local codes (state/county/township).
NOTE: All applicable codes take precedence over any recommenda-
tion made in these instructions.
SECTION III: UNIT INSTALLATION
LOCATION
Access for servicing is an important factor in the location of any furnace.
Provide a minimum of 24" (61 cm) in front of the furnace for access to
the heating elements and controls. This access may be provided by a
closet door or by locating the furnace 24" (61 cm) from a facing wall or
partition.
FURNACE CLEARANCE
Electric furnace is approved for zero (0) in. clearance to combustible
material on all or any part of the furnace exterior and the inlet or outlet
duct work. For furnaces installed in upflow application, there must be
1" (2.54 cm) clearance from the outlet duct work for a distance of 3 feet
(91.4 cm) from the supply air opening.
