Description

Installing a hot water regulator takes only five minutes! ! ! ! !
INSTALLATION STEPS: (PLEASE NOTE: You have to unscrew and screw back 2 plugs, the smaller plug is the oil drain plug and the larger plug is where the heat regulator sits)
Step 1: Remove the old thermal regulator first - you unscrew the smaller plug first, a little water will leak if the system is not closed, Use the shaft of the screwdriver to unscrew the larger plug and keep some inward pressure on the plug to avoid accidental breakouts.
Step 2: Depending on your system, you can do this by turning on the pump or by opening the valve. Once your pump starts to rev, turn on the heater. Your short cycle issue should be resolved. The heater should work normally.
