1. GENERAL
2. INSTALLATION REQUIREMENTS
2.1 MOUNTING CLEARANCES
Series 2300 / IO 210 Heaters must be mounted with minimum clearances as shown in Section 8.4. It
should also be located with respect to building construction and equipment so as to provide sufficient
clearance and accessibility for servicing and cleaning of burners and ignition control. Minimum mounting
height is to be no less than 96”. Do not store or place anything directly underneath heater
2.2 HEATER MOUNTING
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 component.
2.3 GAS SUPPLY LINE INSTALLATION
 All piping must be installed according to local codes.
 An approved flexible connector between the heater and gas piping must be installed. The same is
available as an option from Schwank.
 A drip-pocket at the inlet connection must be provided.
 On propane-fired units, a main line filter is recommended.
 Piping joint compounds must be resistant to the action of liquefied petroleum gases.
 All piping joints should be tested for leaks with a soap and water solution.
Page 1
Series 2300 / IO 210 Heaters are approved for both horizontal and angle mounting. Schwank recom-
mends a maximum 30° mounting angle in most applications - if the short axis is rotated to an angle ex-
ceeding 30°; a large portion of infrared heat may be directed above the heads of seated occupants in
many applications. Refer to Diagram 8. Improper angle mounting can result in damage to the heater or
unsafe operation, and will void warranty.
The gas fired infra-red combined intensity heaters are suitable to be installed for heating of outdoor and
non residential indoor spaces. These installation instructions are intended for the Series 2300 / IO 210
Heaters.
All installations must conform to the following:, all local and national code requirements including the
current CAN/CGA-B149.1 installation code for gas burning appliances and equipment as well as the Ca-
nadian Electrical Code PART 1 CSAC22.1 (latest edition) must be observed. All installations in the
U.S.A. must conform to local and national code requirements including, National Fuel Gas code ANSI
Z223.1, and the National Electrical Code ANSI/NFPA No 70 (latest edition). Due to ever changing stan-
dards and requirements, revision to equipment and installation procedures may be necessary. In case
of discrepancies, the latest installation manual will take priority.
This heater is designed and certified for use on outdoor patio’s in accordance with ANSI stan-
dards CAN1-2.17-M91 & CSA 5.90 (5th ed.) U.S.
Schwank Group warrants that the heater will operate as designed in mild wind conditions up to
10 MPH. Note this unit is not designed to operate in adverse weather conditions including higher
wind speeds exceeding the certification requirement of 10 MPH.

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. The minimum
pressure at the inlet to the heater regulator must be equal to or greater than 6.0" w.c. for natural
gas and 11.0" w.c. for propane gas.
2.4 GAS PRESSURE
a) Properly install gas line as outlined in Section 2.3.
b) Mount heaters by using non-combustible mounting hardware as illustrated in Diagram 2.
Observe the minimum clearances as outlined in Sections 8.4 and suggested mounting dis-
tances in section 8.5
WARNING: When using Wall Mounting Bracket JP-2300-MB, or Arm Mounting Bracket JP-
2300-MA, ensure the anchoring to the structure is of sufficient strength, quality
and workmanship, to support the weight of the heater and any other loads such as
snow.
c) Connect heater to the main gas line. An approved 1/2" flexible connector (available as an
option from the manufacturer) must be used to absorb gas line expansion and any vibration -
check local code requirements.
(d) Check gas line for leakage by using soap test or gas meter test. Ensure gas pressure meets
the requirements out lined in Section 2.4 (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 gas line in excess of 0.5 psig the appli-
ance and shut off valve must be disconnected from the gas supply piping system
during any such pressure testing.
Proper manifold pressure will be maintained when the main burner is operating under the fol-
lowing supply pressure:

4. LIGHTING INSTRUCTIONS
6. HEATER FINISH AND APPEARANCE
Exterior heater surfaces, including stainless steel components, are coated with a black high
emissive coating that helps preserve the aesthetic appearance of the heater and improves the
radiant heat output.
With extended use, the finish coat may discolor and deteriorate to some extent due to the impact
of heat and the deposit of ambient air born particles. In some environments, the stainless steel
lens cover may experience some surface oxidization and discoloration. These are normal occur-
rences caused by heat and products of combustion and in no way affect the operation and per-
formance of the heater or the manufacturer’s warranty.
OCCASIONAL FINISH MAINTENANCE:
Wear protective gloves, eyewear, and breathing mask. Ensure that power to the heater is discon-
nected 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 finish 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 fin-
ish. 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 effect the burner tile surface - insert a paper masking above the lens screen
being coated. Remove the paper masking immediately after re-finish and prior to operation of
the heater.

1. Ensure the correct voltage is supplied and gas valve is in the ON position.
2. Turn on power to heater, set thermostat (if applicable) to desired setting, the heater will light.
3. If heater does not light: Turn off power to heater, turn gas valve to OFF position.
4. Wait for five minutes and repeat steps above. If heater does not light after three attempts, call
a qualified service technician.
e) Ensure proper electrical rating in the system by checking voltage at ignition module
terminals. To avoid system malfunction, the voltage range must be within 21.6 Volts to 26.4
Volts, and correct polarity must be maintained throughout the system.
f) Test-fire the heating system by following the lighting instructions as shown below and on
heater.

9. ELECTRICAL REQUIREMENTS AND THERMOSTAT CONTROL
All electrical installations must meet local and the latest edition Electrical Code PART 1
CSA C22.1 in Canada and ANSI/NFPA N0 70 in the U.S.A.. Single heater requires 24
Volt, 60 Hz electrical transformer sized at 40 VA. If multiple heaters are connected to a
single transformer, the proper transformer is 24 Volt, 60 Hz, sized at 40 VA for the first
heater, and 30 VA each for all subsequent additional heaters. For example, four heat-
ers wired together (parallel), require a transformer of 150 VA. It is recommended to in-
stall at most 2 heaters per zone for best comfort control and economy of operation.
PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the
heaters 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 the local
electrical code. Malfunction of the heating system will result if the voltage varies by
more than +10% or -10%.
The heater can be controlled by a line moisture proof thermostat “off-on” switch, or Re-
mote Control. Total load of all heaters must be considered in determining the required
contact rating of the controlling thermostat or switch.
9.1. REMOTE CONTROL
Patio Heaters can be operated with Remote Control Option; JP-1234-RK and handset
JP-1234-HS. Refer to the manual accompanying the remote control for installation.
Start up - Heat Mode:
On a call for heat the Fenwal 35-60 control will reset, perform a self check routine,
flash the diagnostic LED for up to four seconds. The gas valve and spark are ener-
gized commencing the trial for ignition period. When flame is detected during the trial
for ignition, spark is shutoff immediately and the gas valve remains energized. The
thermostat and main burner flame are constantly monitored to assure the system con-
tinues to operate properly. When the thermostat is satisfied and the demand for heat
ends, the gas valve is de-energized.
Flame Failure - Multi Trial Model:
Should the main burner fail to light, or the flame is not detected during the first trial for
ignition period, the gas valve is de-energized and the control goes through an inter-
purge delay before another ignition attempt. The control will attempt two additional ig-
nition trials before going into lockout and the valve relay is de-energized.
Recovery from lockout requires a manual reset by either resetting the thermostat or
removing 24 volts for a period of 5 seconds. If the thermostat is still calling for heat af-
ter one hour the control will automatically reset and attempt to ignite the burner again.

2300 / IO 210 Manual
IM091231
RD: DEC 2009
R.L. 11B
BA
Flame Failure - Re-Ignition:
If the established flame signal is lost while the burner is operating, the control will re-
spond within 0.8 seconds. The HV spark will be energized for a trial ignition period in
an attempt to relight the burner.
If the burner does not light the control will make two more attempts to relight the
burner before de-energizing the gas valve. If the burner does not relight, the control
will go into lockout as noted above in “Failure to light”. If flame is re-established, nor-
mal operation resumes. Multi-try models will allow three tries for ignition including inter-
purges.
Cautions:
1. Ceramic insulators should not be in or close to the flame.
2. Electrode assemblies should not be adjusted or disassembled. Electrodes should
have a gap spacing of 1/8”- 3/16” (3.12± 0.81 mm). If this spacing is not correct,
the assembly must be replaced. Electrodes are preset and NOT field adjustable.
3. Exceeding the temperature limits can cause nuisance lockouts and premature elec-
trode failure.
The control must be secured in an area that will experience a minimum of vibration
and remain below the maximum operating temperature of 160°F.
Page 14
Flame current is the current which passes
through the flame from the sensor to
ground. The minimum flame current nec-
essary to keep the Fenwal 35-60 system
from lockout is 0.7 microamps (µA). To
measure the flame current, connect analog
DC microammeter to the FC-FC+ termi-
nals.
Meter should read 0.7 µA or higher. If the
meter reads below “0” on scale, meter
leads are reversed. Disconnect power and
reconnect meter leads for proper polarity.

11. SPARK IGNITION CIRCUIT
The step-up transformer in the ignition control provides spark ignition at 30,000 volts
(open circuit). To check the spark ignition circuit, proceed as follows.
1 Shut off gas supply to the gas control
2 Disconnect the ignition cable at the ignition control stud terminal to isolate the
circuit from the spark igniter or igniter/sensor
3 Prepare a short jumper lead, using heavily insulated wire such as ignition cable
CAUTION
In the next step, DO NOT allow fingers to touch either the
stripped end of the jumper or the stud terminal. This is a very high
voltage circuit and electrical shock can result.
1 Perform this test immediately upon energizing the system before the ignition
control goes into safety lockout and interrupts the spark circuit. Touch one end of
the jumper firmly to the ignition control GND terminal. (DO NOT remove the
existing ground lead.) Slowly move the other end of the jumper wire toward the
stud terminal on the ignition control to establish a spark.
2 Pull the wire away from the stud and note the length of gap at which spark
discontinues.
3 A spark length of 1/8 in. (3mm) or more indicates satisfactory voltage output. If no
arc can be established, or the maximum spark is less than 1/8 in. (3mm), and
power to the ignition control input terminals was proved, replace the ignition
control.
