air ports.This unique two-in-one design
allows the stocking wholesaler to cut
inventories in half and still meet most
customer application requirements.
These patentedTrane diffusers provide
an unlimited combination of air diffusion
patterns as well as greater air throw
distance. In fact, when the louver cone
diffuser is added to the Model P, up to 45
percent greater air throw distance is
possible.
Patented Trane louver cone diffusers allow
directional flexibility of heated air.
On Model S units, the combination of
horizontal louver blades and patented
vertical diffuser fins provide four-

The Model S Coil
Compact Design
The Model S unit heater features a
unique single tube serpentine coil.This
compact, efficient coil has piping
connections at the back for added space
savings, convenience and appearance.
Model S single circuit coils use threaded
connectors at the back of the unit.
Trane designed Model S and P propeller
unit heaters for easy installation and low
maintenance.TheTrane Sigma-Flo® fin
design allows coil size to be reduced
while maintaining high capacity
performance equal to larger flat-fin coils.
Reduced size and weight makesTrane
unit heaters easy to handle and install.
The Model P Motor
Rectangular Draw-Thru Coils
The Model P motor is mounted below
the top panel inside the heater casing.
This reduces unit height and permits the
unit to be installed closer to the ceiling
for added headroom.
The Model P draw-thru coils use short
lengths of steel pipe threaded for supply
and return connections.These features
make piping connections much easier
for the installer.

Application
Considerations
General Rules
In locating or spottingTrane Propeller
Unit Heaters – either the Model S
Horizontal or Model P Projection Unit
Heater – the following general rules
should be considered.
1. Spot units at points of greatest heat
loss. Blanket outside doorways
effectively and provide ample coverage
for exposed window areas.
2. Units, especially in the case of the
Model S Horizontal Unit Heater, should
be arranged to blow toward or along
exposed walls, preferably striking the
wall at a slight angle so that the heated
air exerts a wiping effect along the wall.
Balance of units required to supply Btu
requirements should be spaced
strategically in balance of the area.
3. Unit heaters should be arranged to
blow into open spaces such as aisles and
not directly at any worker. An exception
to this rule involves the use of the Model
P Unit Heater equipped with the Louver
Cone Diffuser.This combination can be
used effectively over closely spaced bins
or machines without regard for open
space. But not even the Model P Unit
Heater with Louver Cone Diffuser should
be in such close proximity to the workers
to cause discomfort.
4.TheTrane solid-state speed control will
provide maximum capacity flexibility and
quieter operation. Note that this speed
controller is available only on selected
models.
5. Mounting heights and distance of
throw recommendations as given
elsewhere in this catalog should be
carefully observed.
6. In the case of Model P Units, they
should be spotted so that they will most
effectively prevent stratification of
excessively warm air at the ceiling. By
carefully observing this rule, this type of
unit may be used between seasons to
tap waste heat at the ceiling and drive it
down to occupied zones, thereby
eliminating the need for added heat on
the system.
Figure AC-1 –The floor plan and elevation of a typical industrial building showing how a
Trane Unit Heater System will heat various parts.Where ceilings are high in the main
manufacturing section, large Projection Heaters without diffusers are used.Where ceilings
are exceptionally high, as in crane bays, Model P Units with Louver Cone Diffusers provide
up to 45% greater throw to top the “ceiling heat reservoir.” Model P Units with half closed
Louver Cones blanket doorways. Model S Units with Louver Fins blanket windows.
extremely small height of the Model S,
and because all piping connections are
made at the back of the unit, the Model S
provides a greater saving in headroom
than other horizontal unit heater makes.
As illustrated in Figure AC-1, the Model S
Unit Heaters may be mounted
In plants where the ceilings are
exceptionally high, such as in crane bays
as illustrated in Figure AC-1, Model P
Units with Louver Cone Diffusers can
increase the downward projection of
heat by as much as 45% over units
without diffusers.
conveniently from the ceiling, or from
building structural supports and beams.
With Louver Fin Diffusers, they are ideal
for blanketing windows, and Model S
“Bypass” Unit Heaters, provide further
flexibility of application where greater
throw and more effective distribution of
air in the living zone is required.
Model P Units with the Louver Cone
Diffusers can also be used to blanket
doorways effectively, as shown in Figure
AC-1 by simply adjusting half of the
louvers vertically, and half closed.
Model S horizontal-type units are ideal
for mounting in plant areas where
ceilings are low. In fact, due to the
7. Do not spot units close to any
obstruction that will impede the full and
natural air delivery of the unit.

In the typical industrial building, where
ceilings are high, Model P Unit Heaters
may be used without diffusers.

General Notes
Hot Water System – Using Circulating
Pump
The following general notes on piping
propeller unit heaters are presented
based on competent engineering and
installation practice:
1. Suspend unit heaters securely with
provisions for easy removal.
Overhead supply and return mains are
used with bottom connections to mains.
Manual vent (pet cock) is used at high
point on return main. Automatic air vent
may be substituted if desired. Refer to
Figure AC-2.
2. Make certain units hang level vertically
and horizontally.
3. Provide for expansion in supply lines
(note swing joints in suggested piping
arrangements).
4. Provide unions adjacent to unit heaters
in both supply and return laterals. Also
provide shut-off valves in all supply
laterals.
5. Use 45' angle runoffs from all supply
and return mains.
6. Provide at least 7" (more if necessary)
clearance above tops of Model P
Projection Unit Heaters. Motors are
removable from below on all sizes.
It is desirable to form dirt pockets with
pipe of the same size as the return
tapping of the unit heater. Pipe in the
branch-off should be the same size as the
tapping in the trap. Beyond the trap, the
return lateral should be increased one
size to the return main.
Figure AC-3
High Pressure Steam System
Overhead supply main is used with
lower return main. Where steam
pressure fluctuates over a wide range, a
swing check valve should be placed in
the return lateral between strainer and
bucket trap to prevent reverse flow of
condensate of flash steam when
pressure drops suddenly.Top of bucket
trap must be located below return outlet
of coil for complete drainage of
condensate. Refer to Figure AC-3.

Selection
Procedure
Trane Propeller Unit Heaters
Spacing of Units
oversized heaters to extend the
Both Model S and Model P Propeller
Unit Heaters are ideally suited to such a
wide variety of installations that there
can be no hard and fast rules regulating
their selection.
In determining the type and size of the
units for any building, the following
points are generally considered:
It is the usual practice to divide the
building into areas with like exposures,
or in relation to heat load distribution
desired.
In general, Model S Unit Heaters may
be selected for buildings where direct
horizontal air currents are desired and
where there are no obstacles to
interrupt the flow of air from the
heaters.
Model P Unit Heaters are successfully
used where high or low mounting
heights are required and should
ordinarily be specified with diffusers,
depending upon the mounting height
and application.
maximum effective mounting height of
the Model P or the distance of throw of
the Model S. Conversely,Trane Diffusers
enable extremely low mounting since the
adjustable blades direct heat where it is
wanted without creating uncomfortable
hot spots near the units.
Second: After the original selection has
been made, units may be located with
confidence because adjustments in heat
distribution are possible to
accommodate future changes or
unforeseen draft conditions.
BTU Requirements
While the choice of units depends upon
several important factors, the total Btu
requirement is usually determined first.
In calculating heat loss, methods as
recommended by the ASHRAE Guide
may be used, or any other procedure
which is known to be acceptable.
Air Changes
Better diffusion and more even
temperatures can be maintained in a
heated space when the rate of air
recirculation through the heaters is
relatively high. For buildings where large
numbers of people are engaged, it is
desirable to provide for a greater number
of air changes than for sparsely occupied
areas.
A greater number of small units are used
where wide diffusion and even
temperatures are necessary. A few
centrally located units of large capacity
would be used where there are few
occupants.
Mounting Heights
Type of Building
The maximum effective mounting
height is determined by the outlet
temperature of the air, the outlet
velocity, the cfm for which the heater is
designed, and if a diffuser is used – the
setting of its blades.
The higher the outlet temperature of
the air, the more difficult it is to force it
down into the living zone.
The cfm also affects the mounting
height as a large volume of air will
travel farther than a small volume
under the same initial conditions of
temperature and velocity.
In the preliminary planning stages, it is
well to remember that the lowest
possible mounting height is desirable in
order to get the most heat down to the
floor line and to allow the greatest
possible diffusion adjustment to
provide tailor-made distribution for
each area.
Once the total Btu requirement is known,
the type of building together with its
architecture and its purpose is
considered.
In the many cases where a combination
of space characteristics is found, a
combination of Model S and Model P
Unit Heaters may be used to create the
most satisfactory heating system.
The Model P Unit Heater has the natural
ability to tap the reservoir of heated air
which collects at the ceiling level and
return it to active service in the floor
zone.
The Model P can be used on either high
or low ceilings. From high mounting
positions the Model P will allow ample
clearance for moving objects and can
project heat down into occupied areas
regardless of obstacles which would
restrict the flow of air from horizontal
units.
From low mounting positions the Model
P, with proper diffusion, can be used
without disturbing nearby occupants
with direct blasts of high velocity heated
air, or requiring return lines so low as to
leave insufficient head room.
The superior horizontal action of the
Model S, on the other hand, is ideal for
creating a wiping effect of warm air
along exposed walls which neutralizes
drafts at their source, beaming heat
down narrow aisles and production
lines, and blanketing large windows,
doors and other points of high heat loss.
Comfort Conditions and Economy
Air circulation, diffusion and spacing of
units are closely related to economy and
comfort in the selection of unit heaters.
The more units used to provide the
required number of Btu’s, the more
comfortable will be the conditions for
personnel. On the other hand, a few
large units can be selected to provide
plenty of heat at low first cost, but may
be slower in response and thorough
distribution of heat.
In providing for the use of diffusers
please remember, adjustment of a
Louver Cone Diffuser to deflect the air
toward the horizontal immediately
lowers the mounting height limit.
Adjustment for lateral deflection with
the Louver Fin Diffuser shortens the
distance of throw.
Here again, adjustable diffusion
equipment can go a long way toward
saving the buyer first cost expense while
still providing completely satisfactory
comfort conditions.
Diffusion
The use of Trane Louver Cone or
Louver Fin Diffusers influences the
selection of units in two principal ways:
First: It is seldom necessary to install

1.51 x 185,200 = 279,650 Btu per hour.
Surplus Capacity
Specific weight of one cubic foot of air
(70 F) =.075.
While the ventilation load is being
handled, any air entering the space over
the desired room temperature should be
considered in the heating calculations.
This surplus capacity can be found by
multiplying the difference between the
final temperature leaving the heater and
the room temperature to be maintained
by 1.085 and that by the cfm.That
amount of heat can be used to offset
heat losses.
Cfm x 60 = cfh.
Therefore, .241 x .075 x 60 = 1.085

deflection given the airstream to either
side of the heater.
Maximum mounting heights for Model P
Unit Heaters are given in Table SP-10,
page 19.These distances are figured
from the floor line to the bottom plate of
the unit heater.
Where ceilings are unusually low, a
nearly horizontal flow of air can be
obtained by equipping these units with
Louver Cone Diffusers.The individually
adjustable blades of the Louver Cone
permit an infinite variety of adjustments
to meet any on-the-job problems. By
setting the blades vertically to straighten
the airstream, as much as 45% increase
in throw can be obtained.
Mounting the unit at or below maximum
mounting height will insure that heated
air reaches the living zone.

Notes:
Constant speed units are rated at capacities shown in regular type; capacities in italic faced type apply only to units with multi-speed motors.
To determine BTU per hour capacities at various steam pressures and entering air temperatures, use conversion factors from Table SP-7, page 18.
Final temperatures at new conditions can be calculated by applying basic formula.

Notes:
*LS = Low speed.
**PL = Model P low final temperature model with all air ports open.
Figures in bold face show maximum mounting height with louver cone diffusers set vertically.
To meet CSA and OSHA requirements, Model P Unit Heaters mounted lower than 8.0 ft. from the floor must be equipped with
an OSHA fan guard. Above table based on 60 F entering air temperature. In providing for the use of diffusers, it must be
remembered that adjustment of a LCD to deflect air toward horizontal immediately lowers the mounting height limit.
Step 1.
Determine the MBH at 6.53 GPM by
interpolation in the 200° column. (In this
case 90.8 MBH.) Multiply this MBH by the
conversion factor 90.8 MBH x 1.058 = 96

provide the equivalent MBH at the adjusted WTD. The GPM can then be interpolated from the table at the adjusted WTD. To determine the actual capacity at operating conditions proceed as
outlined in example #2.
If a constant GPM is desired, enter the 200° EWT column at the given or calculated GPM. Select the unit which will provide the equivalent MBH at this GPM. To determine the actual capacity
