INSTALLATION INSTRUCTIONS - MODEL 7770
Propane Gas Leak Detector for Recreational Vehicles
MOUNTING INFORMATION
The recommended location for mounting the detec-
tor is as close to gas appliances as practical; e.g.
near the stove. The recommended height is within
twelve inches from the floor to the horizontal center
line of the detector case (mounting screw location).
Do not mount in closed areas, such as closets.
BLACK WIRE - To ground

nd
RED WIRE if avail-
able to converter
RED WIRE - To battery
If the detector is fused separately, use an
appropriate value fuse for the wire size.
RECOMMENDED LOCATION
INSTALLATION NOTES
The detector will detect gas from both the front
and rear side of its case. If the unit is mounted in
such a way that air cannot flow freely through the
hole on the rear of the case, the unit will not detect
gas from behind.
This gas leak detector is a safety device. It must
not be connected in such a way as to allow it to
be switched off by the use of a wall switch or
similar device or to become disconnected from its
power supply due to the use of a GFCI protected
circuit.
Do not cover or paint over the detector, or allow
the detector to be obstructed. It may not detect
propane gas if obstructed. Exposure of this unit
to an intense electromagnetic field may produce
unpredictable operation. For example, a radio
transmitter in close proximity to the detector may
cause the detector to malfunction when the trans-
mitter is transmitting.

When the coach is equipped with an optional
master cutoff switch for storage only, the detec-

be used with the optional master cutoff switch in
the off position.
