Put Heat Where It’s Needed  
Exclusive louver fin diffusers featured on  
Trane unit heaters put heat where it’s  
needed.  
The Model S features attractive,  
functional styling in a space-saving,  
compact design.  
In addition,Trane offers an exclusive  
bypass Model S design to meet low final  
temperature, high cfm requirements.This  
design uses a modified coil which allows  
some of the air to flow over the top of the  
coil without being heated.This cooler  
band of air prevents the heated air from  
rising so warm air throw is increased  
while efficiency is improved.  
removing the unit’s patented knockout  
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-  
directional control of air delivery.  
Optional low cost louver fin diffusers can  
be adjusted to provide up to 25 percent  
more air throw.

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

Application  
Considerations  
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

Under 40 F and across from 15 lbs. in

multiply the EDR by the same factor in  
the same way.Thus:

Determining Amount of Condensate  
To determine the amount of condensate,  
divide the capacity in BTU by the latent

The capacity of this unit at 30 lbs. steam  
and 40 F entering air is  
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

Maximum mounting heights for Model  
S Unit Heaters are given inTable SP-1.  
When equipped with standard Louver  
Fin Diffusers the distance of throw may  
be increased as much as 25% by “toeing-  
in” the vertical blades. Distance of throw  
decreases in proportion to the amount of  
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.

6.53 GPM. In this example, the selection  
indicates a Model S 126W2 unit heater,  
from Table PD-2, page 28.  
To determine the actual capacity of this  
Model S 126W2 at operating conditions  
(220° EWT and 70° EAT) proceed as  
follows.  
720-P-L  
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  
MBH.  
Step 2.  
The GPM remains constant = 6.53 GPM.  
Step 3.  
Calculate the water temperature drop  
WTD = Btu/hr

Step 4.  
WTD = 27.5 x 0.546 = 15°  
Step 5.  
Determine the pressure drop at 6.53  
GPM. Pressure drops are cataloged for  
both standard wall (SWT) and heavy  
wall. (HWT) tube coils. In this example, if  
a SWT coil is selected the pressure drop,  
by interpolation is 2.38 feet of water.  
Determine the capacity of a Model 336P  
unit heater operating at 180° (EWT), 100°  
(EAT) and 15° (WTD).

Step 3.  
CFM x 1.085  
123,000

Multiply the MBH (interpolated) at  
27.5°WTD, 200° EWT and 60° EAT by the  
factor to obtain the MBH at desired  
conditions.  
= 100°  
+
5210 x 1.085  
0.546 x 224.9 = 123.0 MBH  
Note:  
If a constant water temperature drop is desired, apply the conversion factor to the WTD and to the desired MBH and enter 200° EWT column at these conditions. Select the unit which will  
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  
at operating conditions in this case proceed as outlined in example #1.
