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.
DANGER
Appliances must not be installed where they may be exposed
to a potentially explosive or flammable atmosphere.
WARNING
1. Gas fired heating equipment must be vented - do not
operate unvented.
2. A built-in draft diverter is provided - additional external
diverters are not required or permitted.
3. Gas-fired heating equipment which has been improperly
vented, or which experiences a blocked vent condition may
have flue gases accidentally spilled into the heated space.
See page 15 for specific information about the blocked vent
safety switch supplied on the unit.
4. Modine Manufacturing Company offers power exhausters as
an accessory. Power exhausters not supplied by Modine
Manufacturing Company are not permitted.
5. 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.
6. Gas pressure to appliance controls must never exceed 14"
W.C. (1/2 psi).
7. Disconnect power supply before making wiring
connections to prevent electrical shock and equipment
damage.
8. 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.
9. Any original factory wiring that requires replacement
must be replaced with wiring material having a
temperature rating of at least 105°C.
10. 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 duel
rated units.
11. Ensure that the supply voltage to the appliance, as indicated
on the serial plate, is not 5% greater than the rated voltage.

WARNING
12. 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
owner's risk.
CAUTION
1. Purging of air from gas supply line should be performed as
described in ANSI Z223.1 - latest edition "National Fuel
Gas Code", or in Canada in CAN/CGA-B149 codes.
2. Do not attempt to reuse any mechanical or electronic
ignition controllers which has been wet. Replace defective
controller.
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. Do not attempt to attach ductwork of any kind to propeller
models.
3. To prevent premature heat exchanger failure, observe
heat exchanger tubes. 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 9 and 10 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 trouble-
shooting guide listed in Table 29.1, refer to the applicable
sections of the manual.
6. 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%.
