IMPORTANT: In certain installations, clearances
in Table A & Figure 1 may not be adequate to
keep temperatures below 160°F. In these instal-
lations, it is the installer’s responsibility to insure
that single or multi-heater placement be such that
continuous operation of the heater or heaters will
not cause combustible materials or materials in
storage to attain a temperature of excess of 160°
F.
NOTE: When heaters are installed in proximity to
temperature-sensitive material (for example, vinyl
faced insulation), it is the installer’s responsibility
to insure that the surface temperature does not
exceed the allowable temperature of that mate-
rial. In these installations, minimum clearances
noted in Table A on page 4 are to be increased
by the necessary amount.
Under no circumstances should this heater be
installed in a combustible atmosphere or in a
location where the heater controls can be subject
to ambient temperatures in excess of 150°F.
INSTALLATION IN AIRCRAFT HANGARS
This heater is suitable for use in aircraft hangars
when installed in accordance with the following
standard: NFPA No. 409 (latest edition).
1. A clearance of 10 feet must be maintained
from the bottom of the heater to the highest
surface of the largest aircraft to be housed
in the hangar.
2. A minimum clearance of 8 feet must be
maintained from the bottom of the heater in
other sections of the aircraft hangars, such
as offices and shops.
3. The heater must be located so that it will be
protected from damage by aircraft and other
objects, such as cranes and movable scaf
folding.
4. The heater must be installed where it will be
accessible for serving and adjustment.
INSTALLATION IN COMMERCIAL GARAGES
This heater is suitable for use in commercial
garages when installed in accordance with ANSI/
NFPA No. 88B 1985 (latest edition), which states
clearances to combustible construction or
material in storage, from heater and vent, must
conform to standard NFPA No. 54 (ANSI Z223.1
latest edition), in U.S.A. and in Canada CSA
B149.1-00.
American National Standard Institute (ANSI)
Z223.1 (latest edition) states “overhead heaters
shall be installed at least (8) feet above the floor.”
In addition, they shall be located high enough to
maintain the minimum distance to combustibles,
as shown on the heater rating plate, between the
heater and any vehicles parked below the heater.
INSTALLATION OTHER THAN SPACE HEATING
Use for processing applications voids the
warranty and C.S.A. certification. Any additional
changes, or conversions required in order for the

GENERAL MOUNTING INSTRUCTIONS
The following instructions are a guide to general
installation only. The procedure for installing the
infra-red system is based on structural members
of the building and how they can be used to
support the heating system. Before proceeding
with the installation of the system, we suggest
that you consult your Sterling Distributor for the
proper procedure for your particular job.
Since most installations will differ in many
details, these instructions are general. Sound
judgment must be exercised and careful supervi-
sion is essential to assure the installation will be
made in the best manner possible for trouble-free
operation and at minimal cost.
All systems must be done in accordance with
acceptable practices, local codes, and applicable
standards.
This heater is suitable for reflector mounting
angles up to 30 degrees along the short axis.
Improper angle mounting can result in overheat-
ing of controls and combustible materials.
The hangers support the infra-red heater and the
reflectors.
Chain, with a working load of at least 200 lbs., is
recommended for hanging the heater by connect-
ing the hanger(s) to a beam or other support.
If rigid means such as rods are used in place of
chains, swing joints or other means of sufficient
length must be provided to compensate for
expansion.
IMPORTANT: For either horizontal or angle
mounting, the long axis of the heater must be
level. Use only non-combustible mounting
hardware.
NOTE: It is the responsibility of the installer to
insure that the chosen suspension system will
support at least 200 lbs.

ANGLE MOUNTING
This heater is suitable for mounting angles with the short
axis rotated in either direction as shown in Figure 3.
Improper angle mounting can result in damage to the
heater or unsafe operation.
IMPORTANT: For either horizontal or angle mounting,
the long axis of the heater must be level. Use only non-
combustible mounting hardware. In general, mounting
angles above 25° are only used for special application of
spot and area heating.

VENTILATION REQUIREMENTS
Natural or mechanical means shall be provided to
exhaust at least 4 CFM per 1,000 BTU per hour
input on installed heaters on Natural gas, 4.5
CFM per 1,000 BTU per hour input on installed
heaters on LP gas. Exhaust openings for remov
ing flue products shall be above the level of the
heaters.
When buildings are so tight that normal
infiltration does not provide the necessary air for
combustion, outside air must be introduced.
IMPORTANT: PIPING PRACTICES
1. Installation of ground pipe joint union is
required at the gas inlet connection to the
control valve on the heater. All components
upstream of the control valve are field sup
plied by the installer. See Figure 4.
2. If permitted by code, an approved 18” or 24”
flexible connection between the heater and
piping is recommended.
3. Installation of a 6” gas line trap “Drip-Leg” is
required at the inlet connection to the
heater. Failure to provide a drip leg could
result in condensation and foreign matter in
the valve which could cause damage.
4. On propane-fired heaters, a main line filter
is recommended.
5. Installation of a manual shut off valve is
required. Provide a 1/8 inch N.P.T. plugged
tap, accessible for test gauge connection,
immediately upstream of the gas supply
connection to the heater. It may be part of
the shut off valve as shown in Figure 4.
6. Piping joint compounds must be resistant to
the action of liquefied petroleum gases.
7. All piping must be installed according to
local codes.
8. To insure proper performance and full input
capacity, the gas supply line leading to the
heater from the main supply should be of an
adequate size. Check your local plumbing
codes for correct sizing for your installation.

FIGURE 4

TESTING FOR LEAKS
WARNING
All gas piping and connections must be tested for
leaks after the installation is completed.
DO NOT use a match or open flame of any kind to
test for leaks. Never operate the heater with leaky
connections.
Failure to follow these warnings could result in prop-
erty damage, bodily injury or death.
1. Disconnect the heater and the manual shut off
valve from the gas supply piping system during
any pressure testing .
2. Isolate the heater from the gas supply piping
system by closing the manual shut off valve
during any pressures equal to or less than 1.2
psig.
3. For Steps 4 and 5, apply a soap solution
to all connections and joints. If bubbles
appear, leaks have been detected and
should be corrected.
4. The supply system should be checked
first with the heater gas valve turned
OFF.
5. After the supply is checked, turn the
heater gas valve ON and check the
heater piping and controls while unit is in
operation.
6. The opening between the pipe and the
wall, or floor, through which the gas
piping is inserted should be sealed by
caulking.
MANIFOLD PRESSURE CHECKING
Be sure to check the manifold pressure with a
water manometer to verify proper operation of the
heater.
A pressure regulator is an integral part of the
automatic valve on all models for both Natural
and LP Gas. This pressure regulator will com-
pensate for minor fluctuations in input pressure,
but is NOT a suitable substitute for the line pres-
sure regulator on a Natural or LP gas line.
1. The manifold pressure can be meas-
ured at the 1/8 inch pipe tap on the
control valve. Pressure measurements
should be taken with a water mano-
meter. (Gauges which measure in
ounces per square inch or pounds per
square inch are not accurate enough to
properly measure or set the pressure).
MANIFOLD PRESSURE
(Inches Water Column)
Natural 5.0
Propane/LP 10.0
2. The line pressure can be measured at
the 1/8 inch pipe tap in the main gas
line. Pressure measurements should
be taken with a water manometer.
LINE PRESSURE
(Inches Water Column)
Min. Max.
Natural 6.0 14.0
Propane/LP 11.0 14.0
Input rate should never exceed that shown on the
rating plate. Orifice changes must be made by a
professional gas heating equipment service per-
son.
Natural Gas models are orificed for 1000 BTU/
CU FT gas. Propane/LP Gas models are orificed
for 2500 BTU/CU FT gas. When the actual heat-
ing value differs, an orifice change may be re-
quired.

SPARK IGNITION SYSTEM INFORMATION
Sequence of Operation:
1. Supplies power to the electronic pulse-
generator circuit for the spark igniter.
2. Allows up to 21.6 seconds (maximum) for ig-
nition and 1 try before system safety lockout
occurs.
3. Senses burners flame for safe lighting.
4. Shuts off spark after burners are lit.
The control is powered by a 24 VAC transformer
and activated when the temperature control
requests for heat.
When the control is activated by the temperature
control’s request for heat, control performs a
safe-start check that determines proper operation
of the control before beginning the normal se-
quence of operation. Once the Safe Start Check
operation passes, the control turns on the spark
circuit and at the same time, the control opens
the gas control’s main valves, which allows gas to
flow to the main burners.

MAINTENANCE
The efficiency of the heater can be impaired if it
gets dirty. If the heaters are installed in areas
where considerable dust is present in the air,
periodic burner cleaning may be necessary. Dust
may be entrained in the primary air supply and
deposited on the back side of the ceramic. This
can be very easily removed by dusting the
ceramic face and the air inlet with a blast of low
pressure air, a maximum of 20 psi. Occasionally
pilots or the burners refuse to function properly
after a summer shutdown. The burner passage-
ways can be cleaned out by using a flexible brush
(bottle brush) It is common for spider webs or
cocoons to be found present in these areas.)
Preventative maintenance is the best policy.
Heaters should be cleaned once a heating
season
