Installation as low as 8' above floor

Optional deflector kit for reduced clearances below
Residential And Commercial
– Certified for residential
garage as well as commercial applications
Vacuum System –
Products of combustion are pulled
through the combustion chamber for greater safety ...vir
-
tually eliminates the possibility of combustion gases leak
-
ing into the heated space.
U-Tube Design
– Provides uniform emitter tube temper
-
atures and energy distribution on the floor ...unlike
straight tube heaters which are always hotter at the
burner end than at the exhaust end.
Warranty
– 5-year limited combustion chamber warranty.
Other Features
–
Heat treated, aluminized steel tubes,
aluminum reflectors with 97% reflectivity rating, direct
spark ignition system with 100% gas safety shut-off con-
trol and 30-second prepurge, diaphragm safety switch
for proof of venting, and system indicator lights.
Model Selection
Model numbers are based on
B
TU/Hr input (e.g., 100,000
BTU/Hr), total emitter length
(e.g., 40 feet), and control
s
uffix for gas type (e.g., nat-
ural gas – Single Stage (e.g.
N
5) or Two Stage (e.g. N7)).
For this example, the model
number for a pull through
(negative pressure) straight
tube heater withSingle Stage
natural gas control would be
SIS100-40-N5. For the same
example, the U-tube heater
model number would be
SIU100-40-N5.
For the same example, the
model number for a push
through (positive pressure)
straight tube heater with a
Two Stage natural gas con-
trol would be SPS100-40-N7.
Using the same example, the
U-tube heater model number
would be SPU100-40-N7.

Tough Guy Option
SunStar also offers a “Tough
Guy” option for more corro-
sive and harsh environments
with heat treated aluminized
steel tubes. For the example
above, the model number for
a pull through (negative pres-
sure) straight tube heater
with the “Tough Guy” option
would be SIS100-40-TG-N5.
Note: SunStar's “Tough Guy”
Option is recommended for
dairy barns, greenhouses,
swimming pools, waste water
treatment plants, chemical
plants and other high humid-
ity or corrosive type environ-
ments. Also the SPS or SPU
series with the “Tough Guy”
Option is highly recommend-
ed for car wash applications.
