[. . . ] IMPORTANT: Each millivolt appliance interlocked with the UC1 must have its own Linear Limit spill switch. MULTIPLE MILLIVOLT HEATER INSTALLATIONS Multiple millivolt heaters can be installed by using the A-B dry contact terminals of the UC1, MAC1E or MAC4E. Wire each WHKE gas pressure switch in parallel across A-B terminals of UC1, MAC1E or MAC4E. Wire Linear Limit safety switch into each individual millivolt heater.
