This manual describes the features of the Rinnai outdoor gas water heaters, including micro‑computer control, rain‑proof outdoor installation, and multiple safety protections such as exhaust blockage detection and low‑pressure gas adaptation. The heater is operated via a remote control that can set water temperature from 35 °C to 60 °C in 16 steps and supports up to three remotes with priority switching.
Installation instructions cover connecting the hot‑water and cold‑water outlets (R1/2"), gas inlet sizes (R1/4" for natural gas, R3/4" for LPG), and wiring the remote control. The manual also explains initial startup, temperature adjustment, safety lockout functions, and provides a troubleshooting guide with fault codes displayed on the remote. This manual is written in Chinese.
