2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced flame safeguard
service technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Equipment damage hazard.
Sensing tube can fail to discriminate between
flame conditions.
Change sensing tube after 40,000 hours of continuous
use.
WARNING
Electrical shock hazard.
Can cause serious injury or death.
Disconnect power supply before beginning installation
to prevent electrical shock and equipment damage.
More than one disconnect may be involved.
IMPORTANT
1. Do not connect these detectors to non-Honeywell
manufactured controls (primaries, programmers,
multiburner systems, and burner management
systems). Unsafe conditions could result.
2. All wiring must be NEC Class 1 (line voltage).
3. Voltage and frequency of the power supply connected
to this detector must agree with the values marked on
the detector.
4. Sight the detector so it does not respond to ignition
spark.
5. On multiburner installations, each detector must
respond only to the flame of the burner it is
supervising.
6. Do not connect more than two C7061 Flame
Detectors in parallel.
Proper flame detector installation is the basis of a safe and
reliable flame safeguard installation. Refer also to the burner
manufacturer instructions. Carefully follow all instructions for
the best possible flame detection application.
Basic Requirements
The combustion flames of most carbon-based fuels emit
sufficient ultraviolet radiation to enable the C7061 Solid State
(Purple Peeper) Ultraviolet Flame Detector to prove the
presence of a flame in a combustion chamber. The detector is
mounted outside the combustion chamber with its mounting
flange or union threaded to one end of a sight pipe inserted
through the wall of the combustion chamber. The ultraviolet
sensing tube in the flame detector sights the flame through the
pipe.
When a flame is present, the UV tube in the C7061 senses the
ultraviolet radiation emitted. The C7061 then produces a signal
that is sent to the amplifier in the flame safeguard control. The
amplified signal pulls the flame relay into the control to allow
proper system operation.
Because it is necessary for the UV sensing tube to actually see
the flame, it is best to locate the detector as close to the flame
as physical arrangement, temperature, and other restrictions
permit. These restrictions are described in detail in the
following paragraphs.
