Heater Expansion
It is a normal condition that during heat-up and cool-down a radiant
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection and heater suspension. Improp-
er installation, alteration, or adjustment can result in property dam-
age, injury or death.
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. When used indoors, this heater
is indirectly vented from the space. Venting must be in accordance
with all local, state, provincial, and national codes [ANSI Z223.1/
NFPA 54 in USA; B149.1 in Canada] and as indicated in this manual. Refer to Section 14
Gas Connection
Improper installation, connection, or adjustment can result in proper-
ty damage, toxic gases, asphyxiation, injury or death. Use an ap-
proved stainless steel flexible gas connector [field supplied] to con-
nect to the gas supply to the heater in accordance with all local,
state, provincial, and national codes [ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada] and
as indicated in this manual.
WARNING
WARNING
WARNING Start-up ‘Smoke’ & Discoloration Condition
During start-up, the heating of material coatings used in the production process of the heater
may create a small amount of smoke during the initial period of operation. This condition is
normal and temporary .
Ensure that there is sufficient ventilation to adequately clear any ‘smoke’ from the space.
Notify site management and safety personnel to ensure that alarm systems are not unduly activated.
WARNING Heater Discoloration / Staining
Stainless Steel & Painted Finishes: Surface discoloration or staining will occur on any heater body
due to heat. Surface finish discoloration due to heat is a normal occurrence. Surface discoloration
does not affect the operation or performance of the heater nor the manufacturer’s component war-
ranties. [Refer to Section 12: Heater Finish & Appearance, page 22]
Some discoloration can result from the deposit of ambient air-borne particulate or gases from within
the space that have passed through combustion to create ‘smoke’. The combustion of fuel gas in a
clean environment will not cause smoke discoloration deposits.

Certain materials or items, when stored under the heater, will
be subjected to radiant heat and could be seriously damaged.
Location of flammable or explosive objects, liquids or vapors close to the heater
may cause fire or explosion and result in property damage, injury or death. Do not
use, store or locate flammable or explosive materials in proximity to the heater.
The clearance to combustible material represents the minimum dis-
tance that must be maintained between the outer heater surface and a
nearby surface. The stated clearance to combustibles represents a sur-
face temperature of 117F° [65C°] above ambient temperature when in-
stalled outdoors.
It is the installer’s responsibility to ensure that building materials with a
low heat tolerance which may degrade at lower temperatures are pro-
tected to prevent degradation. Examples of low heat tolerance materi-
als include vinyl siding, fabrics, some plastics, filmy materials, etc.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if
you are uncertain as to the safety or applicability of the proposed installation.
Refer to Table 1 & Figure 1 Next Page for the minimum mounting and clearances to
combustibles for Outdoor Patio application.
DO NOT INSTALL THIS APPLIANCE IN A RECESS, ALCOVE,
OR ENCLOSURE.
Provide adequate free space to allow the products of combustion to escape from the heater
to atmosphere when installed outdoors, or to mechanical exhaust withdrawal when installed
indoors. Do not allow the products of combustion to accumulate in any space or enclosure.
WARNING
INSTALLATION AS AN OUTDOOR PATIO HEATER
What is “Outdoor”?:
An appliance approved for “outdoor use” may be installed with shelter no more inclusive than:
• With walls on all sides, but with no overhead cover, [overhead permanently open] or
• Within a partial enclosure which includes an overhead cover and no more than two side
walls. These side walls may be parallel, as in a breezeway, or at right angle to each oth-
er. The open sides must be permanently open or
• Within a partial enclosure which includes an overhead cover and three side walls, as long
as 30 percent or more of the horizontal periphery of the enclosure is permanently open.
If these “outdoor” conditions are not met, the appliance is approved for “indoor use”
and ventilation requirements of local codes apply.

WHEN INSTALLED INDOORS FOR COMFORT OR SPACE HEAT
• Also refer to “Outdoor” definition and requirements on page 16
• And refer to Indoor Ventilation Requirements Section 14
Clearance to Combustibles
Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire
or explosion and result in property damage, injury or death. Do not use, store or locate flamma-
ble or explosive objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum dis-
tance that must be maintained between the outer heater surface and
a nearby surface. The stated clearance to combustibles represents a
surface temperature of 90F° [50C°] above room temperature.
It is the installer’s responsibility to ensure that building materials
with a low heat tolerance which may degrade at lower temperatures
are protected to prevent degradation. Examples of low heat toler-
ance materials include vinyl siding, fabrics, some plastics, filmy ma-
terials, etc.
In locations used for the storage of combustible materials, signs must be posted to specify the
maximum permissible stacking height to maintain the required clearances from the heater to
the combustibles. Such signs must either be posted adjacent to the heater thermostats or in
the absence of such thermostats in a conspicuous location.
In addition to stored or stationary material, consideration must also be given to moveable ob-
jects such as cranes, vehicles, and overhead doors, and structural objects such as electrical
and gas lines, electrical fixtures, and sprinkler heads.
Heaters must be located an appropriate distance from sprinkler heads. This distance may be
greater than the certified clearance to combustibles. Check the temperature rating of the sprin-
kler heads and locate heaters at a safe distance - in some instances the sprinkler heads may
need to be replaced by higher temperature heads.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you
are uncertain as to the safety or applicability of the proposed installation.

• Within a partial enclosure which includes an overhead cover and no more than two side
walls. These side walls may be parallel, as in a breezeway, or at right angle to each other.
The open sides must be permanently open or
• Within a partial enclosure which includes an overhead cover and three side walls, as long
as 30 percent or more of the horizontal periphery of the enclosure is permanently open.
If these “outdoor” conditions are not met, the appliance is approved for “indoor use”
and ventilation requirements of local codes apply. See “Indoor Application” below.
INDOOR Installation:
This heater is certified for space or spot heating of commercial / industrial non-
residential indoor spaces in accordance with ANSI Z83.19b / CSA 2.35b.
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. Heating system venting must
be in accordance with all local, state, provincial, and national codes [ANSI Z223.1/NFPA 54 in USA;
B149.1 in Canada]. Refer also to Section 14.
INSTALLATION IN A STRUCTURE THAT HAS NO INSULATION IN THE ROOF CAN
RESULT IN THE FORMATION OF CONDENSATION ON COLD SURFACES.

2. INSTALLATION IN COMMERCIAL AIRCRAFT HANGARS
Luminous [high intensity] radiant tube heaters are suitable for use in aircraft hangars when in-
stalled in accordance with the latest edition of the Standard for Aircraft Hangars, ANSI/NFPA
No 409 in the USA, or the Canadian Natural Gas and Propane Installation Code, B149.1.
A. A minimum clearance of 8 ft must be maintained from the bottom of the heater to the floor
in other sections of the aircraft hangar, such as offices and shops, which communicate with
areas for servicing or storage. Refer to Table 1 for clearances to combustibles.
B. Heaters must be located so as to be protected from damage by aircraft and other objects,
such as cranes and movable scaffolding.
C. Heaters must be located so as to be accessible for servicing and adjustment.
3. INSTALLATION IN COMMERCIAL GARAGES AND PARKING STRUCTURES
Luminous [high intensity] radiant heaters are suitable for use in commercial garages when in-
stalled in accordance with the latest edition of the Standard for Parking Structures, ANSI/NFPA
88A, or the Standard for Repair Garages, ANSI/NFPA No. 88B, or the Canadian Natural Gas
and Propane Installation Code, B149.1.
An overhead heater shall be located to maintain the minimum
distance to combustibles, as shown on the heater rating plate,
from the heater to any vehicles parked below the heater.
Overhead heaters shall be installed at least 8 ft above the floor.
4. INSTALLATIONS OTHER THAN SPACE HEATING
Use for process or other applications that are not space heating will void the C.S.A. certification
and product warranty. Process application requires field inspection and/or certification by local
authorities having jurisdiction. Process application design should be provided by local experi-
enced process design experts.
5. PRE INSTALLATION SURVEY
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and obstructions on the site. The certified clear-
ances to combustibles with respect to stored material, moveable objects [cranes, vehicles, lifts,
overhead doors, etc], structural components, and sprinkler system heads. Consideration must
also be given to ventilation fan placement [outdoor heaters do not require ventilation]. Carefully
survey the area to be heated, and for best results place heaters in the coldest area[s] and at
sufficient spacing to provide uniform radiant heat coverage.

6. INSTALLATION REQUIREMENTS
6.1 MOUNTING CLEARANCES
Series 2100 / IO-100 Heaters must be mounted with minimum clearances to combustible ma-
terials. Refer to the introductory section “Clearance to Combustibles” page 6 and to Table 1
and Figure 1 page 7.
THIS HEATER HAS HOT SURFACES: Minimum mounting height is to be no less than 96”
above the floor / deck to the bottom of the heater. Do not locate heater where patrons can
come into contact with heater. Do not store or place items directly underneath heater. Main-
tain clearance to combustibles.
The heater must be located with respect to building construction and equipment so as to pro-
vide sufficient clearance and accessibility for servicing of burner and ignition control and
cleaning . Provide adequate clearance around air openings into the combustion chamber.
6.2 HEATER MOUNTING
Refer to Table 2 and Figure 2. Series 2100 / IO-100 Heaters are approved for both horizon-
tal and angle mounting on the short axis. A maximum 30° mounting angle is allowed to
prevent damage to the heater. Improper angle mounting can result in damage to the
heater or unsafe operation, and will void warranty.
IMPORTANT: For either horizontal or angle mounting, the long axis of the heater must be
level. Use only non-combustible mounting hardware and maintain at least the minimum clear-
ances to combustibles. Also see Pages 11 to 17 and Figures 4 & 5 on Page 12 that illustrate
typical suspension hardware that may be used. Mounting kits can be provided by Schwank as
an optional component.
Installation must conform with all local, state, provincial and national code requirements in-
cluding the current latest edition ANSI Z223.1 [NFPA 54] in the U.S.A. and B149.1 installa-
tion code in Canada, for gas burning appliances and equipment. The latest edition Electrical
Code ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be ob-
served.
The heating system must have gas piping of the correct diameter, length, and arrangement to
provide for and satisfy the total system input. A layout drawing is necessary to calculate
properly sized gas supply piping.
Handle heater with care during installation and service to avoid scratching or damag-
ing the surface finish.
NOTE: MOUNT HEATER AT MAXIMUM 30° ANGLE TO AVOID DAMAGE
THE HEATER MUST BE RIGIDLY MOUNTED TO THE STRUCTURE TO
PREVENT WIND FORCE MOVEMENT.
