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. Im-
proper installation, alteration, or adjustment can result in property
damage, 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 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 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.
Under certain conditions in some locations/environments, surface discoloration may occur on the
heater body due to heat, and products of combustion discharging from the heater. Some discolora-
tion is a normal occurrence and may be the result of the deposit of ambient air borne particulate or
gases within the space that have passed through combustion creating ‘smoke’. The combustion of
fuel gas in a clean environment will not cause any discoloration deposits. Surface discoloration does
not affect the operation or performance of the heater nor the manufacturer’s warranties.

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: Installed Indoor = 90F° (50C°) above room tem-
perature; Installed Outdoor = 117F° (65C°) above ambient 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 tolerance ma-
terials include vinyl siding, fabrics, some plastics, filmy materials, 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. For your convenience, a sign is supplied with this heater - see page 8 for de-
tails. 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.
Refer to Figure 1 and Table 1 NEXT PAGE for the certified clearances to combustibles
for the appropriate model input/size.

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. Schwank recommends a maximum 30° mounting
angle in most applications - if the short axis is rotated to an angle exceeding 30°; a large por-
tion of infrared heat may be directed above the heads of seated occupants in many applica-
tions. 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 prop-
erly sized gas supply piping.
Handle heater with care during installation and service to avoid scratching or damag-
ing the surface finish.

 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
ANSI 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. BASIC ELECTRICAL REQUIREMENTS - see also Section 16 page 23
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 addi-
tional 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 . It is not recommended to install more than 12 heaters per zone.

a) Properly install gas line to all local codes
b) Mount heaters using non-combustible mounting hardware
c) TIP: FOR MOST STABLE HEATER PERFORMANCE IN WIND CONDITIONS:
 Determine if there is a prevailing or predominant wind direction
 If possible, locate the burner end of the heater facing into the direction of the prevailing
wind
d) Observe all minimum clearances as indicated in Table 1 and Figure 1
e) Suggested mounting distances for comfort in Table 2 and Figure 2 are guidelines based
on experience. Site conditions can allow for some deviation from these distances.
WARNING: When using Wall Mounting Bracket JP-2100-MB, or Arm Mounting Bracket JP-
2300-MK, ensure that anchoring to the structure is of sufficient strength, integrity
and workmanship, to support the weight of the heater and any other loads such
as snow.
e) Connect heater to the main gas line. An approved 1/2" flexible connector (field supplied -
available as an option from the manufacturer) must be used to absorb heater and gas line
expansion and any vibration - check local code requirements.
f) Check gas line for leaks by using soap test or gas meter test. Ensure gas pressure meets
the requirements outlined in Section 7.1 (above).
WARNING: When testing the main gas line pressure up to 0.5 psig, ensure that the isolation
valve and combination gas valve are "OFF", otherwise damage to the combina-
tion gas valve will result. When testing main gas line in excess of 0.5 psig the
9. INSTALLATION PROCEDURES
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.

appliance and shut off valve must be disconnected or isolated from the gas sup-
ply piping system during any such pressure testing. Gas supply to the heater
must be regulated to be maximum 0.5 psig (14”w.c.) and minimum values listed
in Table 3 above in Section 7.1
g) All wiring must comply to local and national codes. The heater requires 24Vac power sup-
ply. The heater system zone requires a field supplied 120/24Vac transformer rated at
40VA for the first heater plus 20VA for each additional heater in the zone. Ensure proper
electrical rating in the system by checking voltage at ignition module terminals. To avoid
system malfunction, the voltage range must be within 10% of required 24Vac (21.6 Volts
to 26.4 Volts), and correct polarity must be maintained throughout the system.

11. HEATER FINISH AND APPEARANCE
Exterior heater surfaces, including any stainless steel components, are coated with a black
high emissive coating that helps preserve the aesthetic appearance of the heater and im-
proves the radiant heat output.
Handle the heater with care during installation and service to avoid scratching or damaging
the finish.
With extended use, the finish coat may discolor and deteriorate to some extent due to the im-
pact of heat, the deposit of ambient air born particles, and environmental factors.
These are normal occurrences caused by heat, products of combustion, and the environment,
and in no way affect the operation and performance of the heater or the manufacturer’s war-
ranty.
OCCASIONAL FINISH MAINTENANCE:
Wear protective gloves, eyewear, and breathing mask. Ensure that power to the heater is dis-
connected prior to maintenance and the application of any finish coating. Use a fine steel
wool to remove blemishes or unsightly deposit, and smooth the outer surface. The heater fin-
ish coat can be touched up using a high temperature coating such as Thurmalox Stove Paint -
Flat Black-1200°F (650°C) or similar high temperature stove paint that is compatible with the
original finish.
No other coating or non-high-temperature paint finish may be applied to the heater –
use of an incompatible finish coating could create a hazardous condition such as fire
or noxious fumes, damage the heater, and void the warranty.
Apply the touch up finish with the heater in its operating orientation (facing down). Ensure that
overspray does not reach or effect the egg crate grilles and the burner tile surface - mask the
heater grilles during any re-finishing. Remove the masking immediately after re-finish and
prior to operation of the heater.

To Access Burner for Service
Handle parts carefully to avoid scratching or damaging the surface finish:
1. Remove six sheet metal screws that hold burner end plate in place
2. Remove end plate from heater assembly
3. Slide screen frame from heater assembly
4. Perform 1 to 3 on opposite end to access heater components
5. Reassemble after service
Indication of back firing:
 Loud ignition noise, followed by distinct hissing sound.
 Little or no visible burning on the ceramic tile surface.
 Combustion is taking place inside the burner body.
WARNING: If heater backfires during operation, it must be turned off immediately.
Cause & remedy of back firing:
 Improper gas pressure entering the venturi tube: check pressure.
 Breakage of a ceramic tile and or gasketing: - replace damaged part.
 Faulty sealing of the ceramic tile to the burner body, caused by breakdown of gasket ma-
terial: contact your local distributor or contractor.
Servicing of heater is essential for continued efficient operation. Servicing should be carried
out annually by a qualified gas service technician as follows:
 Clean the ceramic tiles with compressed air. Avoid directing air stream at gasket material
between tile and heater body. The air pressure must be lower than 20 psig.
 Clean venturi tube with compressed air. The air pressure must be lower than 20 psig.
 Ensure gas orifice is clean and the heater cabinet is free of any debris

13. VENTILATION REQUIREMENTS FOR INDOOR APPLICATION
Inadequate venting of a heater may result in asphyxiation, car-
bon monoxide poisoning, injury or death. Heating system venti-
lation must be in accordance with all local, state, provincial, and national codes
(ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada).
This heater is approved for unvented (indirect venting) application. Ensure that there is ade-
quate ventilation to supply combustion air and to dilute the products of combustion in accor-
dance with all local, state, provincial, and national codes. A balanced exhaust / inlet air system
is required to ensure that a negative air condition is not created. See below for a summary of
exhaust capacity requirements by the national codes in the U.S.A. and Canada.
Air Supply: A“loose” building may not require any additional air supply if infiltration rates are
sufficient to offset exhaust volume. However, for “tighter” buildings, or if air movement is stag-
nant in an area, air can typically be supplied via inlet(s) with an area of 1 sq. in. per 1,000 Btuh
input (22 sq cm per kW). Locate air inlet(s) up at the level of the heaters to avoid cold drafts at
work level, and effectively supply combustion and dilution air to the heaters and balance the
system.
Heater Zoning: Exhausters are sized according to the input requirements of each controlled
zone of heaters. Multiple smaller zones are usually more effective in both comfort and ventila-
tion control than one large zone. Maximum zone size is limited by the total input that can be
handled by the capacity of an exhauster, and by the proximity of the exhauster to heaters in the
zone.
Exhauster Location & Proximity: Exhaust must be located as high as practicable in the
structure above the level of the heater(s) to effectively dilute and remove the warm (rising)
products of combustion. The exhauster should be as centrally located as practicable in the
zone of heaters. Schwank recommends a maximum 6:1 ratio of the horizontal distance be-
tween the exhauster and the furthest heater in a zone, to the height the heaters are mounted
above the floor . For example, if heaters are mounted 20 ft above the floor, then the exhaust
fan should be located no more than 120 ft from the furthest heater in the zone. Sufficient air
supply must be provided.
Exhauster Capacity:
USA: Natural or mechanical means shall be provided to supply and exhaust at least
4ft3/min/1000Btuh (0.38m3/min/kW) Natural Gas input of installed heaters [4.5ft3/
min/1000Btuh (0..43m3/min/kW) Propane input]. Some local codes may require an inter-
lock to a dedicated exhaust fan. Consult your local code and ANSI Z223.1 latest edition
for all venting requirements and practices.
Canada: It is required that the heater(s) be electrically interlocked to dedicated exhaust
fan(s) by means of an Air Proving Switch. Exhaust fan(s) must be sized to create 300
cfm (8.5 cu m/min) exhaust for every 100,000 Btuh (30 kW) or any portion thereof of to-
tal input of installed equipment. Provide combustion and ventilation air supply compati-
ble with exhaust volume . Consult the latest edition of CSA.B149.1 Section 7.22.
