SPECIAL PRECAUTIONS
SPECIAL PRECAUTIONS
THE INSTALLATION AND MAINTENANCE INSTRUCTIONS
IN THIS MANUAL MUST BE FOLLOWED TO PROVIDE
SAFE, EFFICIENT AND TROUBLE-FREE OPERATION. IN
ADDITION, PARTICULAR CARE MUST BE EXERCISED
REGARDING THE SPECIAL PRECAUTIONS LISTED
BELOW. FAILURE TO PROPERLY ADDRESS THESE
CRITICAL AREAS COULD RESULT IN PROPERTY
DAMAGE OR LOSS, PERSONAL INJURY, OR DEATH.
THESE INSTRUCTIONS ARE SUBJECT TO ANY MORE
RESTRICTIVE LOCAL OR NATIONAL CODES.
HAZARD INTENSITY LEVELS
1. DANGER: Indicates an imminently hazardous situation
which, if not avoided, WILL result in death or serious injury.
2. WARNING: Indicates a potentially hazardous situation
which, if not avoided, COULD result in death or serious injury.
3. CAUTION: Indicates a potentially hazardous situation
which, if not avoided, MAY result in minor or moderate injury.
4. IMPORTANT: Indicates a situation which, if not avoided,
MAY result in a potential safety concern.
IMPORTANT
1. To prevent premature heat exchanger failure, do not
locate ANY gas-fired appliances in areas where corrosive
vapors (i.e. chlorinated, halogenated or acid) are present
in the atmosphere.
2. To prevent premature heat exchanger failure, the input to
the appliance, as indicated on the serial plate, must not
exceed the rated input by more than 5%.
3. To prevent premature heat exchanger failure, observe
heat exchanger tubes by looking at the heat exchanger
through the field installed access openings in connecting
ductwork or the unit access doors where viewing the heat
exchanger is possible. If the bottom of the tubes become
red while blower and duct furnace are in operation, check
to be sure the blower has been set to the proper rpm for
the application. Refer to page 19 for Blower Adjustments.
4. Start-up and adjustment procedures should be performed
by a qualified service agency.
5. To check most of the Possible Remedies in the
troubleshooting guide listed in Table 54.1, refer to the
applicable sections of the manual.
DANGER
Appliances must not be installed where they may be exposed
to a potentially explosive or flammable atmosphere.
WARNING
1. Failure to follow proper lifting instructions and applicable
safety procedures could result in property damage,
serious injury, or death. Lifting should only be done by a
qualified rigging company. Use ALL lifting points. Test
lift to ensure proper balance and rigging. Never lift in
high winds.
2. All field gas piping must be pressure/leak tested prior
to operation. Never use an open flame. Use a soap
solution or equivalent for testing.
3. Gas pressure to appliance controls must never exceed
14" W.C. (1/2 psi).
4. Disconnect power supply before making wiring
connections or working on this equipment. Follow all
applicable safety procedures to prevent accidental
power up. Failure to do so can result in injury or death
from electrical shock or moving parts and may cause
equipment damage.
5. All appliances must be wired strictly in accordance with
wiring diagram furnished with the appliance. Any wiring
different from the wiring diagram could result in a hazard
to persons and property.
6. Any original factory wiring that requires replacement
must be replaced with wiring material having a
temperature rating of at least 105°C.
7. To reduce the opportunity for condensation, the
minimum sea level input to the appliance, as indicated
on the serial plate, must not be less than 5% below the
rated input, or 5% below the minimum rated input of dual
rated units.
8. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% greater than the
rated voltage.

CAUTION
1. Appliances are designed for outdoor installation only.
DO NOT LOCATE APPLIANCES INDOORS.
2. Purging of air from gas lines should be performed as
described in ANSI Z223.1 - latest edition “National Fuel
Gas Code”, or in Canada in CAN/CGA-B149 codes.
3. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% less than the rated
voltage.
4. Do not reuse any mechanical or electrical component
which has been wet. Such component must be replaced.
(continued from previous column)
9. When servicing or repairing this equipment, use only
factory-approved service replacement parts. A complete
replacement parts list may be obtained by contacting
Modine Manufacturing Company. Refer to the rating
plate on the appliance for complete appliance model
number, serial number, and company address. Any
substitution of parts or controls not approved by the
factory will be at the owners risk.
