A water heater start-up is more than turning on the gas. The set temperature, incoming water pressure, gas and manifold pressure, and recovery time all confirm the unit is safe and performing to spec, and the T&P test, venting check, and leak test confirm it will not become a call-back or a hazard.
Documenting the commissioning protects the customer and your license. It validates the manufacturer warranty, proves the install met code, and gives you a signed baseline if anything is questioned later. It also shows the homeowner that a professional stood behind the work.
