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. Models with Digit 3=G have a built-in draft diverter -
additional external diverters are not required or permitted.
b. Models with Digit 3=P have a built-in power exhauster -
additional external power exhausters are not required or
permitted.
3. If you are replacing an existing heater, it may be necessary to
resize the venting systems. Improperly sized venting systems
can result in vent gas leakage or the formation of condensate.
Refer to the National Fuel Gas Code ANSI Z223.1 or CSA
B149.1 latest edition. Failure to follow these instructions can
result in injury or death.
4. For Models with Digit 3=G, 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 22 for specific information about
the blocked vent safety switch supplied on the unit.
5. For Models with Digit 3=P, under no circumstances should
two sections of double wall vent pipe be joined together
within one horizontal vent system due to the inability to verify
complete seal of inner pipes.
6. 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.
7. Gas pressure to appliance controls must never exceed 14"
W.C. (1/2 psi).
8. Disconnect power supply before making wiring connections
to prevent electrical shock and equipment damage.
9. 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.
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.
12. Any original factory wiring that requires replacement must be
replaced with wiring material having a temperature rating of at
least 105°C.
13. 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.

CAUTION
1. 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.
2. Do not attempt to reuse any mechanical or electrical
controllers which have been wet. Replace defective controller.
3. Ensure that the supply voltage to the application, as indicated
on the serial plate, is not 5% less than the rated voltage.
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 field
installed access openings in connecting ductwork. If the bottom
of the tubes become red while blower and duct furnace are in
operation, additional baffles must be inserted between blower
and duct furnace to assure uniform air flow across the heat
exchanger.
4. To prevent premature heat exchanger failure, with all control
systems, a blower starting mechanism must be provided so
that the blower is running or energized within 45 seconds of the
gas control operation.
5. Start-up and adjustment procedures should be performed by a
qualified service agency.
6. To check most of the Possible Remedies in the troubleshooting
guide listed in Table 20.1, refer to the applicable sections of
the manual.
