Leak Detection & Automatic Shut-Off System
for Conventional Vent Water Heaters
Congratulations on your purchase of a FloodMaster RS-094-MK7 water heater leak detection system
from Reliance Detection Technologies. This product is designed to automatically shut off the water
supply to a water heater or tank if a leak is detected. This kit also provides the capability to cut off
the pilot light signal to shut down gas flow to the tank's burner when a leak is detected, as may be
required by some local codes.
To ensure proper installation and to maximize the performance of your RS-094-MK7 water leak
detection system, please read this manual thoroughly before installing or operating the system.
PLEASE READ CAREFULLY BEFORE PROCEEDING:
If a leak is detected, the RS-094-MK7 will shut off the water going to the water heater. This will stop
the continuous flow of water from the water supply to the tank. However, all or some of the water
that is already in the tank may still leak out onto the floor.
NOTE: This installation and operating manual contains important information about the operation of the
RS-094-MK7 system. If this system is being installed for use by a different user, please be sure a copy of
this manual is left with the system for future reference.
