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 Sec-
tion 13
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Use an approved
stainless steel flexible gas connector (field supplied) to connect 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
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. Discoloration due to heat is a normal occurrence especially with all stainless steel.
Surface discoloration does not affect the operation or performance of the heater nor the manufactur-
er’s component warranties. (Refer to Section 12: Heater Finish & Appearance, page 20)
Some discoloration may be the result of the deposit of ambient air-borne particulate or gases 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.

WHEN INSTALLED AS AN OUTDOOR PATIO HEATER
 see pages 9 - 10 for Indoor installation
 Also refer to “Outdoor” and “Indoor” definitions and requirements on page 11
Certain materials or items, when stored under the heater, will
be subjected to radiant heat and could be seriously dam-
aged.
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 objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum
distance that must be maintained between the outer heater surface
and a nearby surface. The stated clearance to combustibles repre-
sents a surface temperature of 117F° (65C°) above ambient tem-
perature when installed outdoors.
It is the installer’s responsibility to ensure that building materials
with a low heat tolerance which may degrade at lower tempera-
tures are protected to prevent degradation. Examples of low heat
tolerance materials include vinyl siding, fabrics, some plastics,
filmy materials, etc.
It is beyond the scope of these instructions to consider all conditions that may be encoun-
tered. Consult local authorities such as the Fire Marshall, insurance carrier, or safety authori-
ties 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.
WARNING
DO NOT INSTALL THIS APPLIANCE IN A RECESS, ALCOVE,
OR ENCLOSURE.
Adequate free space must be provided 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.

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 flammable 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.

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” [244 cm] 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. Maintain 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. Diagram 2 on Page 5 illustrates typical
suspension hardware that may be used., and provided by Schwank as an optional compo-
nent.
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

7. GAS SUPPLY PIPING
 All piping must be installed according to applicable local and national codes
 A listed flexible connector (field supplied) must be installed between the heater and gas
supply piping. For outdoor installation the connector must be in compliance with AN-
SI Z21.75 / CSA 6.27. A 1/2” x 24” stainless steel flexible gas connector (JL-0771-XX -
approved Indoor/Outdoor) is available as an option from Schwank / InfraSave.
 A drip-pocket must be provided at the inlet connection
 Provide a 1/8” NPT plugged tapping, accessible for test gage connection, immediately
upstream of the gas supply connection to the heater.
 On propane-fired units, a main line filter is recommended (field supplied)
 Piping joint compounds must be resistant to the action of liquefied petroleum gases
 All piping joints must be tested for leaks with a soap and water solution.
CAUTION: DO NOT INSTALL ANY GAS PIPING IN HEAT ZONES
The maximum supply pressure must be limited to 14”w.c. (0.5 psi). If the line pressure is
above 14”w.c., then a separate pressure reducing regulator must be installed in the gas
supply. The minimum pressure at the inlet to the heater regulator (gas valve) must be equal to
or greater than 6.0”w.c. for natural gas and 11.0”w.c. for propane gas.
Proper manifold pressure must be adjusted during commissioning, and will be maintained
when the main burner is operating under the following supply pressure:

8. ELECTRICAL REQUIREMENTS - see also Wiring Diagrams pages 31 - 32
All electrical installations must meet local codes and the latest edition ANSI/NFPA N0 70 in
the U.S.A. and Electrical Code PART 1 CSA C22.1 in Canada .
TRANSFORMER SPECIFICATIONS (field supplied)
Single heater requires 24 Volt, 60 Hz electrical transformer sized at 40 VA.
Multiple heaters in a zone are powered by a single transformer (field supplied). The
proper transformer is 24 Volt AC, 60 Hz, sized at 40VA for the first heater plus 20VA for each
additional heater in the zone - round up the calculated value to the next higher available sized
transformer. For example, four heaters in a zone require a transformer of : 1 x 40VA + 3 x 20
VA = 100 VA .
Natural Gas: Orifice sized for 1000 BTU/CU.FT.
Propane Gas: Orifice sized for 2500 BTU/CU.FT.

PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the heat-
ers in a zone. Total wiring distances of up to 200' must use minimum 16 gauge electrical wire,
and wiring distances of over 200' must use minimum 14 gauge electrical wire. The heater
must be electrically grounded in accordance with local and national electrical codes. Malfunc-
tion of the heating system will result if the voltage varies by more than ±10% .
The heater can be controlled by a line voltage thermostat, a 24 volt thermostat or “off-on”
switch. Total load of all heaters must be considered in determining the required contact rating
of the controlling thermostat or switch.
