Section 1 Description
The Forney IDD flame detector heads are non-repairable devices that generate an AC signal of variable
amplitude and frequency proportional to a burner’s flame intensity. The detector head transmits the signal
through a four-conductor cable to an applicable Forney flame amplifier.
The IDD family of products offers a range of flame detector heads for a variety of fuels / applications.
The major components of the IDD flame detector heads are a metal housing containing a photocell and a
printed circuit board that provides power and amplifies the cell’s output signal. The IR series of detector
heads (-II, -IIU, -IIL, -IICEX, -IIUCEX, -IILCEX) contain a lead sulfide photocell and the UV detector–
ULTRA) heads utilize a silicon carbide cell. The complete assembly is potted with non-repairable epoxy.

1.3 Safety
The IDD model flame detector heads’ voltage point is not accessible under normal operating conditions.
However, users should follow appropriate electrical safety procedure when installing the flame detector.
Electrical power should always be removed from the flame detector amplifier before installing or
replacing a flame detector head assembly. In addition, if a flame detector head must be replaced while the
furnace is in operation, maintenance personnel should exercise caution to avoid exposure to flying
particles and hot furnace gas.
WARNING:
Do Not Open When Energized
WARNING:
When installing and/or removing the IDD model flame detectors, wear safety glasses to prevent eye injury
caused by airborne particles in cooling/seal-air supply or wind box.
CAUTION: The detector head contains sensitive electrical components. Ensure that all power is removed
from the external amplifier assembly before connecting or disconnecting the I/O cable.
CAUTION: Disconnect the cable from the detector by hand, but do NOT twist the connector barrel.
Twisting could cause the wires to become disconnected from solder connections inside the connector barrel.

Section 2 Installation
The IDD flame detectors determine the presence or absence of flame by monitoring the amplitude of the
flame across a flicker frequency spectrum. The detector should initially be mounted so that the primary
combustion zone is within the detector’s line of sight.
The IDD detectors are usually located on the boiler in a position that minimizes radiant or conducted heat
to the detector. In some cases, supplementary cooling chambers may be required. Typical installations
will have either a single union ball valve (front mount) or a “Quick Disconnect” Hansen-type fitting (fiberoptic) for ease of maintenance and a support bracket for the four-conductor cable. Cable support brackets
are not used with supplemental cooling chambers or CEX versions.
Two typical IDD detector installations are “front mount” or direct-view sighting and fiber-optic sighting
used when direct-view sighting is difficult. The detectors systems are shipped with appropriate mounting
equipment from Forney Corporation.
NOTE:
For fiber optic installations refer to Forney Publication 372000-73, Fiber Optic Installations manual.
The location and sighting instructions listed in the following sections are general guidelines for the location
of the detector. Consult Forney for application specific guidance on installation. The detector provides
feedback to a Forney Flame Amplifier which goes onto the burner management system (BMS).
NOTE:
An acceptable detector location must ensure:
Reliable main flame and/or igniter flame detection at all air flow and furnace loads (ranges of fuel
firing).
Rejection of the igniter flame if too short or in the wrong position to ignite the main flame reliably.
When installing a detector head for the first time, ensure the following requirements are satisfied:
The physical mounts are adequate to support the weight of the detector head in the position required
for operation.
The ball valve lever of the cooling-air line moves through its entire operating range without obstruction
from any structure, cable, or hose.
The cooling-air hose and I/O cable do not interfere with the operation of any moving components at
the boiler front. The I/O cable does not contact hot surfaces capable of melting its insulation.
The cable must not run close to any cable or equipment carrying high voltage to keep interference to
minimum.
2.1 Installation Procedure
WARNING: Protective filtered lenses should be worn when viewing flame; infrared and ultraviolet energy
from the flame can be damaging to the eyes.
1. The best results are obtained when the detector is aimed so that the detector’s line of sight
intersects the burner center at a slight angle (e.g. 5 degrees) and sees a maximum of the primary
combustion zone, as shown in Figure 3. If only one detector is used per burner, the line of sight
should also intersect the igniting flame.
2. For installations where separate detectors are used to monitor main and igniter flames, the main
7
Page 9
IDD Flame Detector Heads Manual
372000-05 Rev J
flame detector should be sighted so it does not detect the igniter flame.
3. The detector should have an unrestricted view of flame as far as possible. Physical obstructions
such as air register blades, interfering vanes, or other hardware should be cut away or notched
so they do not fall within the detector’s line of sight as shown in Figure 3.
Note: Always check with the burner manufacturer before you trim the register blades.
2.1.1 IDD-CEX Mounting Flange
The IDD-CEX Housing requires an additional mounting flange for installation. See arrangement
drawings
Flange Material: Cast aluminum with gray polyester powder coat finish. Contains an integral heatinsulating female thread insert (external heat-insulating nipple not required).
Flange Threads: 1" NPT female pipe mount with 3/8” NPT female cooling air connection.
1" BSP female pipe mount with 3/8” BSP female cooling air connection.
Flange Weight: 0.62 lbs (0.28 kg)
Note: When installing the flange, only torque to 60 in/lbs (5 ft/lbs or 6.8Nm) on the sight pipe, else it may
damage the threads. (Hand tight plus 1 turn max)
Figure 3 Detector Sighting
4. AN ACCEPTABLE DETECTOR LOCATION MUST ENSURE THE FOLLOWING:
Reliable target flame detection.
Rejection if target flame is too short or in the wrong position
Note: Reliable signals must be obtained throughout the range of air flows and furnace loads (ranges of fuel
firing) and to meet the requirements of flame failure logics of the burner management system

Figure 4 Detector Location VS. Secondary air rotation
5. If combustion air enters the furnace with a rotational movement of sufficient velocity to deflect
pilot flame in direction of rotation, position the detector 0 to 30 degrees downstream of the
pilot burner and close to the periphery of the throat where the ultraviolet radiation is at a
maximum. (See Figures 3 and 4)
Having determined an appropriate location for the sight tube, cut a clearance hole for a 2 inch
pipe through the burner plate. If register vanes interfere with the desired line of sight, the
interfering vane(s) should be trimmed to assure an unobstructed viewing path at all firing
levels, see example shown below.
Note: Always check with the burner manufacturer before you trim register vanes.
FLAME MUST COMPLETELY COVER SIGHT OPENING
6. The preferred method for mounting surface mounted detectors requires the use of a swivel
mount, shown in Figures 6, 8, 10 and 12. Center the swivel mount over the two inch hole in
the burner plate and secure using three hexed cap screws (not provided). Install the sight pipe
on the swivel mount. If a swivel is not used, insert the end of the sight pipe into the hole, align
the hole to the desired viewing angle and tack weld (welding must be adequate to temporarily
support the weight of the installed detector). The sight pipe should be arranged to slant
downward so that dirt and dust will not collect inside.
CAUTION: Use no more than one foot of one inch diameter sight pipe. Increase the sight pipe diameter
one inch for every additional foot of sight pipe length used to avoid restricting the detector’s field of view.
7. When a satisfactory sighting has been confirmed by operational testing, secure the swivel
mount’s ball position in place by tightening the three hex head cap screws located on the swivel
mount ring.
8. The detector lens must be kept free of contaminants (oil, ash, soot, dirt) and the detector housing
temperature must not exceed its maximum heat rating. Excessive temperatures will shorten
detector life. Both requirements will be satisfied by a continuous injection of purge air at either
the 3/8" inlet at the flange housing or the 1" wye connection ahead of the swivel mount as
shown in Arrangement Drawings.
9
Page 11
IDD Flame Detector Heads Manual
372000-05 Rev J
The detector mounting may be made with provision for purge air through only the 3/8" inlet or the 1" wye
connection. Normally purge air is provided through the 1” wye and the 3/8” inlet is plugged.
It is good practice to use the sealing coupling (P/N 9114793 NPT, 9114782 BSP) on all installations to
insure against unwanted furnace pressures from damaging the detector lens. When a sealing coupling is
used, the 1" wye connection is used for the purge air and the 3/8" opening is plugged. The sealing coupling
is located in front of the detector, behind the 1” wye/valve.
Under normal conditions, with clean burning fuels and moderate ambient temperature conditions, purge air
flow of approximately 10 SCFM (283 l/min) is generally adequate. Up to 15 SCFM
(425 l/min) may be required for fuels that produce high levels of ash or soot, or for hot environments to
maintain the detector’s internal temperature within specification.
NOTE:
If freezing temperatures are expected at the detector head, Forney recommends heat tracing the detector
sight tube. Contact Forney for additional details.
CAUTION: To ensure safe and reliable detection it is the responsibility of the commissioning engineer to
carry out flame failure testing after programming the detector.
Ensure that the detector correctly detects the target flame (Flame On condition) and recognizes the target
flame off (Flame Off condition).
Refer to Parts section at the end of this manual for applicable part numbers of items shown in arrangement
drawings.

Refer to specific Forney Amplifier manual for specific wiring instructions for other amplifiers.
Section 3 Commissioning
Before commissioning, complete all of the installation instructions.
3.1 Checkout Procedure
3.1.1 Initial Checkout
Verify the interconnection between detector head and the amplifier; confirm to applicable wiring diagram
for the specific amplifier.
1. Verify the operation of the detector head as follows:
a) Remove mounted IDD detector head.
b) Connect it to the four-conductor cable.
c) Place a light source 1 to 4 feet from the surface of the detector. Use a Tungsten light source for IR
detector heads and a UV light source for the IDD-Ultra.
d) At the signal input terminal of the detector amplifier, measure the signal with either a digital
voltmeter (DVM) or oscilloscope to be 0.1 to 8.0 vac, peak to peak.
e) Remove all light supplied to the detector cell, and verify loss of signal.
2. After checkout, return the system to normal configuration.
3.1.2 Operational Checkout
1. With burner in service, verify signal input to the detector amplifier.
2. Adjust the amplifier per the applicable Forney Corporation service manual.
3. Amplifier gain / frequency adjustments must be made by cycling target flame on/ off and changing
the target burner firing rate from minimum to maximum. Settings must be verified during burner
operation at different boiler loads to ensure discrimination requirements are met.

372000-05 Rev J
Section 4 Operation
The IDD detector head is sighted at the first 1/3 of the flame or the primary combustion zone of the burner.
The radiant energy from the flame is viewed either directly through a straight piece of pipe or transmitted
to the surface of the detector cell through a fiber-optic assembly. The cell in the detector on which the
radiant energy falls is biased with a +50 vdc source. As the intensity of the flame’s radiation increases and
decreases, it causes a change in resistance of the cell substrate. This resistance change in turn creates a
varying ac voltage output that is proportional to the amount rate of change of the radiant flame energy.
IMPORTANT:
The detector must be sighted properly to sense sufficient flame radiation. Improper sighting may cause
detector failure due to a weak or non-existent signal.
The signal is transmitted to the applicable flame detector amplifier through a four-conductor shielded cable.
The output signal from the IDD detector head is totally dependent on the flame radiation from the burner
and the sighting of the primary combustion zone.
Section 5 Troubleshooting
If the detector head malfunctions, ensure that the procedures described in the commissioning section have
been performed successfully.
