INSTALLATION

When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
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.
NOTICE
Per industry standards, a conduit seal or a cable type that
is sealed is required to be installed in a device that can
result in flammable gas or flammable liquid flow through a
conduit or cable to an electrical ignition source in the
event of a seal leakage or diaphragm failure.

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. The C7061 is powered from the Flame Safeguard unit
that delivers the necessary voltages to operate the
sensing tube and shutter.
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 (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 nut
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 energizes the flame relay in the control to allow
proper system operation.
