Space-Ray PTS 40 User manual

At Space-Ray, industrial comfort heating is a challenge we take seriously. We have
been manufacturing gas-fired infrared heating systems since 1949. The quality and
performance of our heaters are based on over 50 years of field experience and ex-
posure to a wide variety of industrial heating problems. Our reputation is built upon a
solid track record for providing radiant efficient, easy-to-install and high quality in-
frared heating equipment.
Space-Ray infrared tube heaters are ideal for complete building heat or even spot heat-
ing needs.The best applications include: manufacturing plants, warehouses, auto deal-
erships, aircraft hangars, loading docks, weld shops, truck or auto service areas, car
washes, fire stations, greenhouses, gymnasiums, garages, machine shops, tennis
courts, swimming pools, maintenance shops, farm buildings and many many more.
Space-Ray infrared heaters heat like the sun by transferring radiant heat energy directly
to the areas to be heated. Radiant energy is absorbed by concrete floors, objects and
people, and re-radiated to warm the surrounding area.This principle is similar to the sun’s
radiant heat energy heating the Earth but not the upper atmosphere. This heating tech-
nology creates a comfort zone at floor level, not at the ceiling, and is much more efficient
than conventional forced air heating systems.
A highly radiant efficient Space-Ray infrared heating system can normally save a build-
ing owner 30% to 50% in annual fuel costs when compared to forced air heating sys-
tems. n fact, some Space-Ray customers report fuel savings as high as 70% with a
payback of less than one year.With a Space-Ray system, your investment payback ac-
crues not only from reduced energy costs, but from reduced maintenance costs, too.
So when you think industrial heating, think Space-Ray. Call us at 1-800-438-4936 for
the name of our representative nearest you.

How the TISS™ Works
Space-Ray’s innovative safety feature T SS
provides the ultimate in fire safety protection available
for positive pressure radiant tube heaters. n the unlikely event that
the heat exchanger tube burns through, a flame will penetrate the tube,
melt the reflector, and rapidly increase the temperature above the heater. The
exposed flame will potentially set fire to any combustible materials that were previously
safe distances away from the heater. The revolutionary T SS uses a simple principle to place an electrically
charged insulated aluminum wire in tension above the reflector. When the heat increases
due to heat exchanger failure, the wire melts, the safety circuit is broken and shuts down the gas controls.

Space-Ray’s newly developed Tube ntegrity Safety System*
(T SS) provides peace of mind. t may never be needed, but
in the unlikely event of a tube failure, you will be happy that you
have a T SS. t is simple. A low voltage circuit
continuously monitors the clearance above the
reflector for excessive overheat and tube
integrity compromise. You may never
know it is there, but on a positive
pressure tube heater it is nice to
know you have the T SS.

COMBUSTION AIR AND VENTILATION
Combustion air and venting requirements or all gas- ired heating equipment must be provided per the National Fuel Gas Code NFPA54 or the authority having jurisdiction over the
installation. In contaminated atmospheres or high humidity areas, optional outside air or combustion can be supplied. Heaters can be common vented, vented, or indirect vented.
Re er to the Installation and Operation Instructions or urther in ormation. A vented installation must be vented to the outside o the building with a lue pipe. An Indirect vented in-
stallation requires a minimum ventilation low o 4 CFM per 1000 Btu/hr o total installed heater capacity on natural gas by either gravity or power ventilation (4.18 CFM per 1000 Btu/hr
or propane). For indirect vented applications, building exhaust openings must be located above the level o the heaters and inlet air openings must be located below the level o the
heaters.
FOR YOUR SAFETY
OPERATE SPACE-RAY GAS INFRARED HEATERS WITH PROPER CARE AND OBSERVE ALL SAFETY PRECAUTIONS. Installation and service must be per ormed by a licensed con-
tractor. The installation must con orm to local codes. In the absence o local codes, the installation must con orm to the National Fuel Gas Code ANSI Z223.1 (latest edition, also known
as NPFA54) or CAN / CSA-B149 installation codes (latest edition). These codes are available rom the National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269
or the Canadian Gas Association, 55 Scarsdale Road, Toronto, Ontario MB3 2R3 Canada.

*When used indirect vented, clearances to ceiling from top of exhaust hood must be 12” on PTS/U (50-75), and 18” on PTS/U (100-200). If optional corner or U-bend reflec-
tors are not used, clearance must be 18”. **Clearance below the tube reduces to 72” 20 ft. downstream from the control box. Note: Consult factory if reduced clearances
are re uired.
This chart is intended as a guide only, as heaters may be mounted at various heights and angles. Since straight tube heaters are always hotter at the burner end
than at the exhaust end, always observe the minimum recommended mounting heights shown above and mount heaters as high as possible. Use PTU series for
spot heating. Please consult your local Space-Ray Representative for a detailed analysis of your particular infrared heating requirements.
