Hazards Include:
For maximum safety the building must be evaluated for hazards before installing the heater system.
Examples include, but are not limited to:
• Gas and electrical lines
• Combustible and explosive materials
• Chemical storage areas
• Areas of high chemical fume concentrations
• Provisions for accessibility to the heater
• Adequate clearances around air openings
• Combustion and ventilating air supply
A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustibles is defined as the minimum distance you must have between the infrared surface, or reflector,
and the combustible item. Considerations must also be made for moving objects around the infrared heater.
The following is a partial list of items to maintain clearances from:
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
Combustible Items Include: Moving Objects Include:
• Wood • Overhead doors
• Paper • Vehicles on lifts
• Fabric • Cranes
• Chemicals • Hoists
• Wall or roof insulation • Car wash equipment
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room
temperature. Building materials with a low heat tolerance (such as plastic, vinyl siding, canvas, tri-ply, etc.)
may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent
materials are protected from degradation.
When installing the infrared heater system, the minimum clearances to combustibles must be maintained.
These distances are shown in Chart 1.1 and on the heater. If you are unsure of the potential hazards, consult
your local fire marshal, fire insurance carrier, or other qualified authorities on the installation of gas fired
infrared heaters for approval of the proposed installation.

2.0 Installation
WARNING
Read and understand, the installation, operating, and maintenance instructions
thoroughly before installing or servicing this equipment.
Only trained, qualified gas installation and service personnel may install or service this
equipment.
CAUTION
This heater cannot be used in a building with an uninsulated roof or condensation problems can occur.
Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct placement
of the infrared heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on
page 5), you should take also into consideration the environment (e.g., cold/drafty, average, protected),
heat coverage (sq. ft.) needed, heater centers, the distance behind a person or work station(s) and exhaust
path. Also, the effective infrared surface temperature of a person or object may be diminished with wind
above 5 mph. Wind barrier(s) may be required. Most importantly, clearance to combustibles must always
be maintained! Refer to hazards on page 4.
This installation manual, along with national, state, provincial, and local codes, address these issues. It is
critical that you read, understand, and follow all guidelines and instructions. Always inspect and evaluate the
mounting conditions, space for exhaust, gas supply and wiring.
Perimeter mounting of infrared heaters provides the most effective distribution of heat. The recommended
spacing between the heaters is shown in Chart 2.1. Add additional heaters in the center of the space when
heaters are spaced farther than the recommended distance (see Figure 2.1 ).
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.)
can evaporate. This may result in odors or fumes being emitted into the environment. To correct this problem,
clean the area and/or introduce additional ventilation. Heaters installed and serviced in accordance with the
installation manual do not emit foul odors into the environment.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater. This
distance may exceed the published clearance to combustibles. Certain applications will require the use of
high temperature sprinkler heads or relocation of the heaters.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in
conjunction with this heater without careful consideration for, and avoidance of, potential fire or explosion
hazards. For further information, consult NFPA 13. Always observe applicable state and local codes.

WARNING
Improper suspension of the infrared heater may result in collapse and being crushed. Always
suspend from a permanent part of the building structure that can support the total force and
weight of the heater.
Failure to maintain minimum clearance to combustibles may result in fire and/or explosion,
property damage, serious injury, or death. Always maintain minimum clearances and post
signs or provided tags (F/N: LL01) where needed. Signs should state the hazards for the
particular application and be legible to the building occupants. Consult the factory or a
factory representative for additional information on signage compliance.
An approved connector, suitable for the environment of equipment usage, is required.
Visible or excessive swaying, flexing, and vibration of the gas connections must be avoided
to prevent failure. Neither the gas pipe nor the connector shall be placed in the ‘flue
discharge area’. In no case shall the gas supply support the weight of the heater.
The heater can be suspended with chains or rigid threaded rod. Local codes or conditions that would cause
the unit to move (e.g., wind drafts, blowers, crane rails, etc.) may require rigid threaded rod. Consult all
applicable codes before installation.
The heater must be level from side to side and between 20° and 35° from horizontal. The pilot burner or
ignitor, manifold, and controls must be located on the lower end. Refer to Figure 2.3.

2.0 Installation • Ventilation
Ventilation
WARNING
Insufficient ventilation may result in health problems, carbon monoxide
poisoning, or death. Vent enclosed spaces and buildings according to
national, state, provincial, and local codes.
Improper venting may result in asphyxiation, fire, explosion, injury, or death.
It is required that the levels where heaters are mounted be properly ventilated to supply combustion air to
the heaters and to sufficiently dilute the products of combustion. It is also required that the flue discharge
area is kept clear of gas piping and electrical wiring (see Figure 2.4).
This infrared heater must be vented in accordance with national, state, provincial, and local codes and the
guidelines in this manual. In the United Sates refer to the latest edition of ANSI Z223.1 (NFPA 54) and in
Canada refer to the latest edition of the CAN/CGA B149.1 & B149.2 Standard.

SIDE VIEW
Provisions must also be made to provide sufficient fresh air intake area and exhaust air outlet area. For
proper ventilation, a positive air displacement of 4 CFM/1,000 BTU/h of gas consumed mus be provided.
Where insufficient air movement exists, induced air displacement is required. A balanced system is essential
to avoid negative building pressure which causes excessive infiltration, unfavorable drafts, and affects
combustion efficiency.
Air displacement may be accomplished by either natural or mechanical means. Mechanical exhausters are
preferred and typically mounted at high points on the roof where stagnant air accumulates inside the building.
For a flat roof, considerations of prevailing winds, high and low pressure areas, and distribution of air
movement must be taken into consideration when locating exhausters.
Manifold/Control
End Down
Best air distribution is accomplished by using a number of small exhausters versus one large exhauster.
Provide a minimum of one square inch of inlet area per 1,000 BTU/h for combustion air supply. Inlet
opening in the building should be well distributed (see Figure 2.1) high in the sidewalls and should direct
incoming air upward to dilute products of combustion while preventing drafts at lower levels. Inlets are
typically 1 to 3 sq. ft.
Local codes may require that mechanical exhaust systems be interlocked with heaters to enable both to
function simultaneously (see page 17, Figure 2.6) or allow control of exhausters with a ceiling mounted
humidistat.
2.0 Installation • Gas Supply
!
IHR Series Manual
Gas Supply
WARNING
Improperly connected gas lines may result in fire, explosion,
poisonous fumes, toxic gases, asphyxiation, or death. Connect
gas lines in accordance to national, state, provincial, and local
codes.
The gas supply to the infrared heater must be connected and tested in accordance with national, state,
provincial, and local codes along with the guidelines in the Modine Manufacturing Company IHR Series
manual. In the United States refer to the latest edition of the ANSI Z223.1 (NFPA 54) Standard and in
Canada refer to the latest edition of the CAN/CGA B149.2 Standard.
Important! Before connecting the gas supply to the infrared heater(s):
• Check that the gas piping and service has the capacity to handle the load of all heaters being
installed, as well as any other gas appliances being connected to the supply line.
• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.
• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas

2.0 Installation • Gas Connection
To connect the gas:
WARNING
Failure to install, operate, or service this appliance in the approved manner may result in
property damage, injury, or death.
An approved connector, suitable for the environment of equipment usage, is required.
Visible or excessive swaying, flexing, and vibration of the gas connections must be
avoided to prevent failure. Neither the gas pipe nor the connector shall be placed in the
‘flue discharge area’. In no case shall the gas supply support the weight of the heater.
This heater must be installed and serviced by trained gas installation and service personnel only.
The installation of this heater must conform with local building codes or, in the absence of such codes, the
National Fuel Code (NFPA 54).
The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within
or run through any wall, floor or partition.
The IHR Series heater is equipped to receive a gas supply line nipple of 1/2” NPT Schedule 40
1
metallic pipe. All piping must be installed in accordance with the requirements outlined in the National
Fuel Gas Code ANSI/Z223.1 (latest edition) or CSA B149.2. Support all gas supply with pipe hangers,
metal strapping, or other suitable material. Do not rely on the heater to support the gas pipe.
Form the stainless steel flexible connector (field supplied) into a smooth C-shape allowing 12 in.
2
between the flexible connector’s end nuts. Figure 2.5 on page 16. NOTE: Not for use on rigidly
mounted heaters.
Install a ground joint union with a brass seat and a manual shut off valve adjacent to the unit for
3
emergency shut off and easy servicing of controls. A 1/8” NPT plugged tap that is accessible for a test
gauge connection is also recommended.
A sediment trap must be installed in the supply line in the lowest spot prior to connecting to the heater.
4
The trap length shall be at least three inches long. Ideally, the trap would be installed as close as
possible to the shut off.
When connecting piping to the unit, the use of a thread joint compound is required. The thread
5
compound (pipe dope) shall be resistant to the action of propane gas or any other chemical
constituents of the gas to be conducted through the piping. Use of Teflon
®
tape is not permitted.
WARNING
Always use two (2) opposing wrenches to tighten mating pipe connections
to prevent excessive torque on the gas valve and manifold pipe. Excessive
torque can damage the valve and/or misalign the orifice, resulting in fire,
explosion, serious injury, or death.

Leak Testing
WARNING
Use a soap solution or equivalent for leak testing. Never test for leak with an open flame.
Failure to comply could result in personal injury, property damage, or death.
Always leak test final gas assembly for gas leaks according to the procedures outlined in NFPA 54 and all
local codes and/or Standards.
For leak testing on pressures below ½” PSI
Before leak testing, close the field installed manual shut off valve shown on Figure 2.5 on the supply line
to isolate the gas valve from the pressure.
NOTE: All factory installed gas connections have passed an approved leak test.
For leak testing on pressures above ½” PSI
When leak testing with pressures above ½” PSI (14 inches W.C.), the unit must be isolated from the
supply pipe. Close the field installed manual shut off valve, disconnect the supply line to the unit, and
temporarily cap the supply line for testing purposes.
Gas pressures to the appliance controls must never exceed 14 inches W.C. (1/2” PSI).
Supply pressures greater than 14” W.C. can damage the controls, resulting in personal
injury, property damage, or death.

2.0 Installation • Electrical Requirements and Wiring Diagrams
Electrical Requirements and Wiring Diagrams
WARNING
Shock hazard. Disconnect power supply before making wiring connections to prevent
electrical shock and equipment damage. Any original factory wiring that requires replacement
must be replaced with wiring material having a temperature rating of at least 105°C.
All field installed wiring to the unit heater must be must be done in accordance with the national, state,
provincial, local codes, and to the guidelines in this manual. In the United States, refer to the most current
revisions to the Electrical Code ANSI/NFPA 70 and in Canada refer to the most current revisions to the
Canadian Electrical Code CSA C22.1 Part 1. The unit must be electrically grounded according to these
codes. Line polarity must be observed when making field connections.
CAUTION
The power supply to the heater must be within +/- 5% of the voltage rating as indicated on the rating
plate of the appliance. If input power does not meet these specifications, contact your utility company.
Before proceeding with electrical connections, ensure that the supply voltage, frequency, phase and
current capacity meet the requirements specified on the rating plate. A dedicated line voltage supply with
properly sized wire should run directly from the main electrical panel to the heater. The power to the unit
must be protected with a circuit breaker appropriate for the load. The unit must be electrically grounded
in accordance with local codes, or in their absence, with the latest edition of the National Electrical Code,
ANSI / NFPA 70 and/or the Canadian Electrical Code CSA C22.1, latest edition.
Control systems are initiated by either 120 VAC, 24 VAC or millivolt energy. The 120 VAC systems can be
used directly from a 120 VAC line. On 24 VAC systems, transformers must be used to supply power of
sufficient VA rating for single or multiple connected installations.
Millivolt systems require NO external power, as energy needed to operate the valve is developed by the
power-pile generator. Do not use multiple connections, as one thermostat may only control one heater.
For wiring of controls on the unit, see the Figure 2.6 below. It is recommended that the thermostat be
installed on the hot side of a fused supply line and have sufficient ampere capacity rating for the heater(s)
it will control. The ventilation system may not be controlled separately from the heating system (consult
local codes) by the use of a humidistat that closes then the humidity rises. The humidistat control should
be installed at roof level. For summer ventilation, a simple on/off switch can be installed at the occupant
level.

3.0 Operation • Lighting Instructions
3.0 Operation
WARNING
Do not attempt to ignite a direct spark ignition heater by hand. Failure to comply could
result in personal injury, property damage, explosion, fire, or death.
Upon satisfactory completion of the electrical supply and purging of the gas supply line to the heater(s),
follow the lighting instructions on the heater’s rating label to put the heater into operation.
Direct Spark Ignition
Lighting Instructions
Rotate the heater’s valve knob to the “ON” position.
1
Close electrical circuit (typically the thermostat).
2
If the heater fails to light, turn off gas, open electrical circuit and wait 5 minutes before repeating the
3
above steps.
Shutdown Instructions
Open electrical circuit.
1
Rotate the heater’s valve knob to the “OFF” position.
2
Sequence of Operation
Starting Circuit: Upon a call for heat, voltage is applied to L1 and Neutral. After a pre-purge, the spark
electrode is energized and the gas valve opens. The trial for ignition is 15 seconds. If flame is not sensed,
the heater will attempt two more times to reignite.
Running Circuit: After ignition, the sensing electrode monitors the burner flame. If sense of flame is lost,
the control immediately acts to reignite the gas-air mixture. If flame sense is not established within 15
seconds, the heater will attempt two additional ignition sequences before proceeding to hard lockout. The
control can be reset by briefly interrupting the power source.
Millivolt
Lighting Instructions
Purge main gas supply line.
1
Slightly depress and rotate the heater’s manual gas valve knob COUNTERCLOCKWISE from the
2
“OFF” position to the “PILOT” position.
Fully depress the manual gas valve knob and light the pilot burner. Continue to depress for 30
3
seconds and then release.
Rotate the heater’s valve knob to the “ON” position.
4
Close the control circuit. If the heater fails to light, turn off the gas, open control circuit and wait 5
5
minutes before repeating the above steps.
Shutdown Instructions
Open the control circuit.
1
Rotate the heater’s valve knob to the “PILOT” position, depress slightly and rotate to the “OFF” position.
