Fig. 5. C7061 mounting positions.
To mount a C7061M (see Fig. 6):
1. Hold the unit securely with one hand to prevent it from
2. Tighten the mounting nut approximately 4 turns with the
other hand until the unit is held securely in place.
3. Make sure the unit is properly aligned in the vertical
plane when viewed from the front.

DO NOT TILT
DO NOT MOUNT
DO NOT MOUNT
Be sure the C7061M is properly aligned vertically
when seen from the front. If not, the shutter may
be damaged or malfunction.
File any burrs or protrusions from the monitoring
pipe. If the packing in the mounting nut is dam-
aged, any chance of leakage may be caused.
Do not use a tool such as a pipe wrench when
tightening the mounting nut. Excessive torque by a
tool could damage the packing and compromise
Do not adjust the mounting pose by forcibly hold-
ing the unit or wiring pipe. Failure to do so may
damage the packing and compromise the seal.
Equipment damage hazard.
Improper wiring can permanently damage amplifier.
When using the C7061 and the R7861 Dynamic
Self-Check Amplifier, be careful not to short the white
shutter leadwires together (by wiring incorrectly, leaving
an incorrect jumper wire, or stripping the insulation too
much so the bare leadwires can touch).
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.
1. All wiring must comply with applicable local electrical
codes, ordinances, and regulations. Use NEC Class 1
2. Keep the flame signal leadwires as short as possible
from the flame detector to the terminal strip or wiring
subbase. Capacitance increases with leadwire length,
reducing the signal strength. The maximum permissible
leadwire length depends on the type of leadwire and
conduit type and diameter. The ultimate limiting factor in
flame signal leadwire length is the signal voltage. Refer
to Table 1.
3. The C7061M1008 detector has color-coded plastic-insu-
lated, no. 18 leadwires, 8 ft (2.4m) long, rated for 221°F
(105°C). These wires must be run in a conduit. The
C7061M1016 has a Brad Harrison® Type 41310 connec-
4. If the leadwires are not long enough to reach the termi-
nal strip or wiring subbase, make the required splices in
a junction box.
5. If splicing is necessary, use moisture-resistant no. 14
wire suitable for at least 167°F (75°C) if the detector is
used with a flame safeguard primary control, or at least
194°F (90°C) if used with a flame safeguard
6. For high temperature installations, use Honeywell
specification no. R1298020 wire or equivalent for the F
leadwire. This wire is rated up to 400°F (204°C) for
continuous duty. It is tested for operation up to 600 volts
and for breakdown up to 7500 volts. For the other
leadwires, use moisture-resistant no. 14 wire selected for
a temperature rating above the maximum operating
