5. Setup
5.1. Startup Inizjali
After professional installation, follow the specific startup procedures outlined in the comprehensive installation manual provided with the unit. This typically involves purging air from the gas lines and checking for leaks.
5.2. Settings tat-Temperatura
The available temperature settings range from 100°F to 140°F, with a default setting of 120°F. Adjust the desired temperature using the control buttons on the unit's digital display.
6. Istruzzjonijiet Operattivi
The Rheem RTGH-90DVLP-3 provides continuous hot water on demand. When a hot water faucet is opened, the flow sensor activates the unit, and the control board determines the required heat based on inlet water temperature and flow rate. Burners ignite, and water is heated as it passes through the heat exchangers.
6.1. Hot Start Programming
This exclusive feature keeps the water heater in a ready state for 5 minutes after a faucet is turned off. This minimizes cold water bursts during back-to-back uses, such as washing dishes or taking multiple showers.
6.2. Overheat Film Wrap
The unit includes an Overheat Film Wrap for heat exchanger overheat protection. In the event of overheating, this safety feature will melt and shut down the unit to prevent damage.
