IMPORTANT
The use of this manual is specifically intended
for a qualified installation and service agency.
A qualified installation and service agency must
perform all installation and service of these
appliances.
Inspection On Arrival
1. Inspect unit upon arrival. In case of damage, report it
immediately to transportation company and your local factory
sales representative.
2. Check rating plate on unit to verify that power supply meets
available electric power at point of installation.
3. Inspect unit received for conformance with description of
product ordered (including specifications where applicable).
General Information
Installation and service instructions in this manual are applicable
to the three types of steam/hot water unit heaters which should
be installed in their proper applications for their most effective
function as overhead heating units.
The copper condensers are warranted for operation at steam
or hot water pressures up to 150 lbs. per sq. in. gauge, and
or temperatures up to 375°F, cupronickel tube units are
warranted for operating pressures up to 250 PSI and operating
temperatures up to 400°F. Canadian Standards Association
(CSA) requriements state that explosion-proof units may not
be used with a fluid temperature in excess of 329°F and still
maintain their explosion-proof rating, for national electric code
ignition temperature rating T3B for grain dust.
Motors are designed for continuous duty. They can operate in a
maximum ambient temperature of 104°F (40°C).
The unit heaters are listed by the Canadian Standards
Association as certified and Canadian Registered heat
exchangers CRN OH 9234.5.
CAUTION
Do not remove outlet fan guard from vertical
type unit heaters.
Steam horizontal and vertical delivery unit heaters are available
in both standard and low-outlet temperature models. Low outlet
temperature models are recommended primarily for installation
on heating systems with steam pressures of 30 to 150 PSI.
When used at these steam pressures they provide lower outlet
air temperatures for longer heat throw and, because of wider
fin spacing, they are less susceptible to clogging in dusty
atmospheres.
The model number of each unit heater indicates its rated Btu/Hr.
capacity/1000 at 2 lbs. steam pressure and 60°F entering air
temperature. For example an HSB-63 has an output of 63,000
Btu/Hr. at 2 lbs. steam and 60°F entering air.

UNIT LOCATION
DANGER
Appliances with power codes 01, 02, 04, 05, and 10 must
not be installed where they may be exposed to a potentially
explosive or flammable atmosphere.
1. Units should not be installed in atmospheres where
corrosive fumes or sprays are present.
2. Be sure no obstructions block air intake or air discharge of
unit heater.
3. Locate horizontal delivery unit heaters so air streams of
individual units wipe the exposed walls of the building
with either parallel or angular flow without blowing directly
against the walls. Heaters should be spaced so the air
stream from one supports the air stream from another
heater. See Figure 3.1.
4. Columns, machinery, partitions, and other obstacles should
not interfere with air streams from unit heaters.
5. Unit heaters installed in a building exposed to a prevailing
wind should be located to direct a major volume of heated
air along the windward wall of the building.
6. Large expanses of glass, or large doors that are frequently
opened, should be covered by long-throw unit heaters such
as large horizontal delivery of “Power-Throw” unit heaters.
7. Vertical delivery unit heaters should generally be located in
the central area of the space to be heated. Place horizontal
delivery units along the walls of the same building where
heat loss is usually greatest. See Figure 3.3.
8. Arrange horizontal delivery units so they do not blow
directly at occupants. Air streams from this type of unit
should be directed down aisles, into open spaces on the
floor, or along exterior walls.
9. When only vertical delivery units are installed, they should
be located so exposed walls are blanketed by their air
streams. See Figure 3.2.

Installation
UNIT MOUNTING
CAUTION
Do not install units below 8 feet measured from the bottom of
the unit to the floor.
Do not install unit above recommended maximum mounting
heights. Height at which unit heaters are installed is critical.
Maximum mounting heights for all units are listed in Table 4.1
and the height dimensions are shown in Figures 4.3 through
4.7. Maximum mounting heights for vertical models are given
for units with or without optional air deflectors. The data in
Table 4.1 is based on operating conditions of 2 lbs. steam or
220°F entering water with 60°F entering air. When operating
conditions are other than those above, refer to Figure 4.2 for
maximum mounting height correction factor. To obtain the
maximum mounting at actual operating conditions, multiply
the appropriate factor from Figure 4.2 by the mounting height
in Table 4.1. The maximum mounting height for all units is that
height above which the unit heater will not deliver heated air
to the floor at standard rating conditions.
Figure 3.2
Unit Locations of Vertical Units In Narrow Buildings
Deflector Mounting
If an optional air deflector has been furnished for vertical units,
it is always shipped separately and can be attached to the unit
before suspension. Vertical louvers for horizontal units and
horizontal louvers for “Power-Throw” units can also be added
and positioned before installation. Cone-jet and louver-type
deflectors must be attached with angle brackets and machine
screws to the bottom cover of the unit. Refer to mounting
instructions which are furnished with each deflector.
Depending on supply or return piping arrangement, there is
a possibility of interference between certain anemostat air
deflectors and piping on some vertical air delivery unit heaters.
Check dimensions.

UNIT SUSPENSION / INSTALLATION
UNIT SUSPENSION
Horizontal delivery units, Model HSB/HC Series. All horizontal
delivery units, except Models HSB-18 and HSB-24, have two
tapped holes (1/2"-13) in the top for unit suspension. HSB-18
and HSB-24 models do not require independent suspension and
are installed directly on their supply piping. Models HC have two
tapped holes (HC 18-86 3/8"-16, HC 108-340 1/2"-13) in the
top for unit suspension. Piping support hangers or clamps are
recommended and should be placed as close to the unit heater as
possible. For other models, independent suspension can be made
with threaded rods, pipes, or ceiling hanger brackets. See Figure
5.1.
Vertical delivery units. Vertical delivery Models V/VN-42 through
V/VN-279 have four tapped holes (1/2"-13) in the top cover for unit
suspension. Unit suspension for these models can be made with
threaded rods, pipes or ceiling hanger brackets. Models V/VN333 through V/VN-952 are equipped with an angle-iron mounting
bracket that has eight 5/8-inch diameter hanger holes permitting
hook-hoisting and suspension with cables, if desired. A 1/2-inch Ubolt, 3-inch center can be inserted in the two holes at each end of
the bracket to accommodate suspension with four threaded rods,
pipes or hanger brackets.
Power-Throw horizontal delivery units. “Power-Throw” units are
designed for horizontal air delivery and are equipped with hanger
brackets for suspension. Three hanger brackets are supplied for
Model PT/PTN-279, one on the front, and two on the rear panel for
three-point suspension. Only two hanger brackets are furnished
on the front panel of Models PT/PTN-333 through PT/PTN-952
(for required four-point suspension use the two hanger brackets
on the front panel and the two holes on the ends of the upper
angle supports at the rear of the unit). Each hanger bracket has a
5/8-inch diameter mounting hole for hook-hoisting and suspension
with threaded rods, pipes, or cables.
Note: A pipe hanger adapter kit as illustrated in Figure 5.1 is
available as an accessory from Modine. The kit consists of two
drilled 3/4-inch I.P.S. pipe caps and two capscrews to facilitate
threaded-pipe suspension. One kit will mount a Model HSB 33340 or HC 108-340 horizontal delivery unit. Two kits are required
to mount a Model V/VN vertical delivery unit.
Figure 5.1
Unit Suspension
hot water systems, include a balancing valve in return line for
water flow regulation. A drain valve should also be provided
below each unit heater to allow removal of water from the
heating coil if located in an area subject to freezing.
3. In steam or hot water systems, rapid air removal is required
because entrained air is a cause of corrosion. Hot water
systems should be equipped with suitable air vent valves for
rapid and complete removal of air at the high points and ends
of both supply and return mains. Proper air venting for steam
systems can be achieved by use of a steam trap with an
internal air vent.
4. Traps must be located below the outlet of the unit. Consult
trap manufacturer for specific recommendations. Each steam
unit heater should be provided with a trap of sufficient size
and capacity to pass a minimum of two times the normal
condensate released by the unit at the minimum differential
pressure in the system. Trap capacity is based on the
pressure differential between supply and return mains. Steam
systems should be equipped with a float and thermostatic
trap or an inverted bucket trap with an air bypass.
5. It is advisable to use a pipe line strainer before each steam
trap draining a unit heater. This protection will reduce the
maintenance of the steam trap. When strainers are used they
should be installed between the unit heater and the trap and
be the same size as the trap tapping. In order to catch dirt
and scale, the strainer should have a screen perforation size
smaller than the trap orifices.
6. On systems where the steam supply to the unit heater is
modulated or controlled by a motorized valve, a vacuum
breaker should be installed between unit outlet and the trap.
If a vacuum breaker is used, it should be in conjunction with
a float and thermostatic trap.
7. Install a scale pocket at bottom of unit heater to collect dirt
and scale as shown in illustrations. Pipe diameter must be
the same size as unit connections and about six inches long.
8. Provide adequate pipe hangers, supports, or anchors to
secure the piping system independently of the unit heater.
Electrical Connections
WARNING
1. Disconnect power supply before making wiring connections
to prevent electrical shock and equipment damage.
2. 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.
3. Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature
rating of at least 105°C.
4. Ensure that the supply voltage to the appliance as indicated
on the serial plate is not 5% greater than the rated voltage.
Piping - See Figure 6.1
1. Branch piping to and from unit heater should include swing
joints to allow for expansion and contraction of the piping
without placing a strain on the unit heater element. On steam
systems, the branch piping should be taken off and returned
above the centerline of the supply and return lines.
2. Install pipe unions and shut-off valves in lines to and from
each unit heater to allow maintenance or replacement of
unit without shutting down and draining entire system. For
CAUTION
1. Do not install units below 8 feet measured from the bottom
of the unit to the floor.
2. Do not reuse any electrical component which has been
wet. Such component must be replaced.
3. Ensure that the supply voltage to the appliance, as indicated
on the serial plate is not 5% less than the rated voltage.
1. Installation of wiring must conform with local building
codes, or in the absence of local codes, with the National
Electric Code ANSI/NFPA 70 - Latest Edition. Unit must be
electrically grounded in conformance to this code. In Canada,
wiring must comply with CSA C22.1, Electrical Code.

2. Electric wiring must be sized to carry the full load amp draw
of the motor, starter, and any controls that are used with
the unit heater. All units with power codes 04, 05, 09, or 10
(polyphase motors) must be provided with suitable
overcurrent protection in circuit supplying heater at
installation. Overcurrent protectors should be sized based
on motor current rating shown on the unit serial plate, and
applicable national electric code procedures.
All units are provided with an electrical junction box.
Junction boxes are either integral to the motor or attached
to the unit casing. Units with explosion-proof motors have
an explosion-proof junction box attached to the motor.
Any damage to or failure of Modine units caused by
incorrect wiring of the units is not covered by Modine’s
standard warranty.
3. Location of room thermostat, when supplied, should be in
the natural circulating path of room air. Mount thermostat
about five feet above floor level where it will not be affected
by heat from the unit or other sources of drafts that would
prevent it from properly controlling room temperature. See
instructions packed with the thermostat.
4. Speed controllers furnished with specified unit heater fan
motors, are packed separately and must be connected
according to wiring diagram with each controller.

HC, PT/PTN) or top (V/VN) of the unit heater.
Automatic Control Operations
Install one of the following operating systems for continuous
automatic control.
Intermittent Fan Operation — Hot Coil
A room thermostat starts and stops the fan motor. An aquastat
is sometimes strapped to the return piping to prevent fan
operation when heat is not being supplied to the unit heater.

MAINTENANCE / SERVICE
All heating equipment should be serviced before each heating
season to assure proper operations. The following items may be
required to have more frequent service scheduled based on the
environment in which the unit is installed, and the frequency of
the equipment operation.
Motors
A. Cleaning
Remove grease and dirt on motor during each inspection
or lubrication. Open frame motors should be blown clean
every heating season, or whenever condensers are cleaned,
whichever is sooner.
B. Lubrication
1. Lubricate motor according to manufacturer’s instructions
located on the motor.
2. When no motor oiling instructions are on the motor, oil
the motor every two thousand hours of operation with
SAE20 motor oil for units in normal applications. Adjust
oiling according to usage and atmosphere.
3. Some motors do not have oil fittings. These motors are
lubricated for long life and do not require further lubrication.
C. Overload Protection
A change in line voltage higher or lower than motor nameplate
rating may cause overheating and serious motor damage.
Check plant voltage conditions. A separate manual starter with
thermal overload protection device is recommended for those
units that do not have motors with built-in overload protection.
Condensers
A. Cleaning
Clean condenser at least once a year; more often under
unfavorable conditions. Unless condenser is kept reasonably
free of dirt, lint and grease, its original heating capacity will be
reduced — possibly to a serious degree, and motor damage
may result.
Two commonly used cleaning methods are:
1. Loosen dirt by brushing fins on side where air enters
condenser and then turn on fan to blow dirt from unit.
2. Use high pressure air hose to loosen dirt by blowing from
side where air leaves condenser (side adjacent to louvers on
blow-through units; side adjacent to fan on draw-through units).
For thorough cleaning of condenser, remove motor and fan and
spray a mild alkaline cleaning solution over the condenser. After
a few minutes, follow by a hot water rinse. (A steam gun can be
used for spraying cleaning solution and hot water.)
Condensers subjected to corrosive fumes should be checked
and cleaned frequently.
B. Internal Corrosion Safeguards
1. Provide controlled water treatment — don’t use excess of
boiler compounds. Contact your boiler compound supplier for
proper usage or the services of a water treatment laboratory.
2. Periodic internal flushing of the coils is recommended in
areas where water supply is suspected of causing scale.
Use an alkaline-chelant solution and introduce it at the main
pump of the hydronic system. Flush thoroughly.
WARNING: USING INORGANIC OR MINERAL ACIDS SUCH
AS MURIATIC (HYDROCHLORIC) ACID, EVEN THOUGH
INHIBITED, AMY LEAD TO SEVERE DAMAGE, INCLUDING
CORROSION AND LEAKAGE.
3. De-aerate boiler feed-water (particularly if large amount of
new water is used).
4. Insure rapid continuous and adequate condensate drainage
by properly sized and installed traps and piping. Check traps
for sticking. Clean strainers ahead of traps. (When traps
don’t work, condensate accumulates in unit heater coil; water
hammer results.)
5. Adequately vent each unit.
6. Use low pressure steam when possible.
Casings
A. Cleaning
Periodic cleaning of casings is recommended to remove dirt,
grease and corrosive substances that may injure finish. Rusted
or corroded spots should be cleaned and repainted.
B. General Inspection
