Lufran Water Heaters, Stack Light Test Menu

Hello. I’m Ed Dulzer with the Process Technology Technical Support team here in the high-purity product testing area. I want to show you how to best utilize the stack light test menu in a Lufran Water Heater. The stack light test menu is accessible through the main operating menu. The navigation button across the bottom is how you access the stack light test menu. This menu allows you to test the individual stack lights by pressing and holding the individual test buttons. You can confirm normal operation of these lamps whenever you want. These two lower button here allow you to use instead of a solid light, you can use a flashing light. And simply press them again to turn off the flashing feature. And that is how you can access and use the stack light test menu in a Lufran water heater. Thank you.
