Features & Accessories
Rupp Air is dedicated to producing the right direct-fired
system designed and engineered with the smallest of details
in mind to give unmatched performance. Our continued
commitment to quality and mechanical reliability means that
each system has to be hassle free to install, and will supply
fresh, clean, tempered air to any indoor environment.
Rupp Air’s direct-fired gas heaters economically replace
exhausted air by delivering replacement air at a constant
temperature regardless of outside temperature. Rupp Air
direct-fired heaters can also be designed to heat a space
with a minimum introduction of fresh air to insure the
highest efficiency heating system.

and Warranty
Each Rupp Air direct-fired heater has been designed to
use the most fuel efficient burner technology available
with up to a 30:1 turndown capacity. The use of these
high efficient heaters will not only heat your space but
will also help eliminate drafts, replace contaminated or
stale air, eliminate temperature stratification, and create a
positive building pressure – necessary for good indoor-air
quality – while maintaining comfort levels.
Rupp Air has developed an easy to use selection software program, enabling the user to specifically design the exact heater
to meet the application criteria. The Result...year round,
cost effective comfort.

Constant Volume System
The constant volume 100% direct-fired make-up air
system heaters provide a constant rate of supply air
to the space. The gas flame in the unit heats the fresh
make-up air directly, eliminating energy losses associated
with other types of heating. For most applications,
introducing slightly more make-up air into the space
than what is exhausted produces the best results. A
slightly positive building pressure assures the best
performance. Some applications, such as the commercial
kitchens, require more air exhausted than introduced
to control over pressurization of the kitchen.
4
Two-Speed System
The two-speed, direct-fired make-up air system functions
the same as constant volume, however provides two
different air-delivery rates by using either an 1800/900
RPM motor or 1800/1200 RPM motor.
Two-speed units offer flexibility to buildings with two, fixedexhaust loads or where an increase of airflow is desired.
Units for buildings with two fixed-exhaust loads should
have CFM ratios that match the available two-speed
motor RPM ratios. The low speed is interlocked with the
first exhaust fan, while high speed operates when both
exhaust fans are running, allowing one unit to handle
two different exhaust loads.
The use of the discharge reduction damper in this
s y stem offers a low cost up front investment with the
same operation benefits of the VFD. By closing the
reduction damper, the output CFM is reduced. This design
has the ability to be setup as a two position CFM rate unit
or a varying CFM unit based off pressure in the space.
Both VAV systems have been designed with additional
safety features and controls to insure safe burner operation.
The example on page 4 illustrates the use of a two
speed unit for transit or automotive type facility. Low
speed is used for general ventilation and heating.
However, if the co-detector senses high limits of carbon
monoxide, the two speed unit goes to high speed and
the second exhaust fan turns on to ventilate the space.
There are many uses for the two-speed system, however
another use is for paint booths designed for painting and
curing of paint. High speed use in paint mode and low
speed is used in curing mode to dry the painted surface.
80/20 System
80/20 systems can be a variable make-up air unit, a
total-building heat unit, or a combination of both. By recirculating air, this system provides the most efficient
building heat system.
Variable Air Volume System
The variable air volume (VAV) system allows variable
amounts of make-up air through one heater. This system
allows a heater to turn down to as low as 25% of its
designed CFM by use of a variable frequency drive
(VFD) or airfoil blade designed discharge reduction
damper. One unit can handle varying exhaust loads by
changing the CFM out put of the unit. This system is
ideal for spaces that have multiple exhaust loads and
recirculated air is not an option.
The use of the VFD in the system offers the highest level
of operating efficiency of any of the direct fired systems,
using only the required electrical energy to provide the
CFM needed. The VFD can be setup to operate in many
different ways to change the CFM required to the space.
A potentiometer can be used to manually position output
CFM, multiple set points can be set in the VFD to vary
output CFM, or a building pressure control device can be used
to vary output CFM by sensing pressure in the space.
One unit can handle multiple and varying exhaust loads
as a variable, make-up air unit using the 80/20 System.
This system offers constant discharge airflow but varies
the amount of outside air introduced to the building. With
the use of the 403M or the 404M space-temperature
control system, the unit can be a complete buildingheating system for either fixed or variable exhaust loads.
The 80/20 System supplies at least 20% outside air to
the building and mixes with re-circulated room air at a
maximum of 80%, without the return air re-circulated
through the burner. A building-pressure switch controls
the modulating-burner bypass and return-air dampers
introducing more outside air as the building’s exhaust
load changes. The varying exhaust-air loads automatically
and continually adjust the amount of make-up air
introduced into the system.
All Rupp Air direct fired systems are provided with terminals to
integrate operation with the building exhaust system.
For more information on this system please see our “80/20 Systems Catalog”
or contact your local sales office.

Selecting The Rupp Air
M a n a g e m e n t S y s t e m To
M e e t Yo u r N e e d s
Rupp Air has developed a simple to use computer
selection program to help you select every type of
direct-fired heater system and configuration outlined
in this catalog. However, before making the proper
RAMS direct-fired heater selection you will need to
know some of the following items.
➊ Determine the best direct-fired heater system
from pages 4-5 that meets your needs.
❷ Calculate desired supply CFM, this will be determined
by your exhaust CFM volume or CFM required to
heat your space such to offset infiltration, additional
CFM may be added to pressurize the space slightly.
❸ Determine temperature rise or BTU’s of heating
required.
– For make-up air applications, temperature rise
(delta T) can be determined by subtracting the entering
16
air temperature (EAT) from the leaving air temperature (LAT) which is typically your winter design
t e mp e r a t u r e .
______ LAT
— ______ EAT
______delta T
– For heating of a space, BTU’s can be calculated
by figuring heat loss in your space and adding this to
the heat required to temper the infiltration CFM (ICFM)
and the exhaust CFM (ECFM) in the space.
______ BTU’s Heat Loss
+ ______ (ICFM + ECFM) x 1.08 x delta T
_ _ _ _ _ _ Total BTU’s
❹ Determine static pressure loss of all external ducting
and accessories (The Rupp Air selection software will
calculate pressure drop through accessories automatically, however a quick reference accessories pressure
drop table is available below).

❺ Determine location of unit indoor or outdoor; ground
or roof. (An illustration of options available can be
found on pages 8-9).
❼ Determine supply voltage.
❻ Determine arrangement of unit from drawings below.
❽ Determine control system from pages 10-11.
❾ Determine accessories and options required for
application from pages 8-9.

Rupp Air’s selection program has been designed to
provide you with a complete selection of the heater
that best fits your needs, along with a detailed specification and complete as-built drawings.
If selecting the correct model and horsepower is all
you need at this time, you can simply use the performance data found on pages 18-26. Keep in mind that
“external static pressure” is duct static plus Rupp Air
accessories. After a model has been selected, drawings
for that model can be found on pages 12-15.
Now that you have compiled the required information
you can now effectively size the direct-fired system to
meet your needs using the Rupp Air easy to use stepby-step selection program. For assistance in selecting
a unit, simply contact your local Rupp Air sales office
or call Rupp Air directly at 1.800.291.2452.
