Safety first: Turn off power or gas and allow water to cool before disassembling any fittings.

Check valves: Ensure any shutoff valves on the hot outlet from the Giant heater are fully open.
Inspect heat traps: Many Giant heaters use heat trap nipples. If clogged, they can be removed and cleaned or replaced.
Clean mixing valve: If installed, disassemble and descale the thermostatic mixing valve.
Flush lines: Open several hot taps to flush debris after any work.
