Installation Procedures
Proper installation is crucial for optimal performance. This involves a recess box‚ gas inlet‚ water connections‚ and power lead connection – follow the guide carefully.
Recess Box Installation
The Rheem Metro Max 26 water heater offers space-saving installation with a recess box‚ allowing for a neat‚ built-in appearance. Before beginning‚ ensure the chosen wall cavity meets the required dimensions for safe and secure housing of the unit.
Carefully position the recess box within the wall‚ ensuring it is level and firmly secured to the wall studs. Proper support is vital to prevent any movement or vibration during operation. Connect the necessary plumbing and gas lines to the appropriate inlets and outlets on the unit before fully enclosing it within the recess box.
Finally‚ ensure adequate ventilation around the recess box to comply with local gas safety regulations. Refer to PAGE 4 of the product data for detailed diagrams and specifications regarding recess box installation.
Gas Inlet Connection
Crucially‚ all gas connections must be performed by a licensed gas fitter‚ adhering strictly to local gas regulations and standards. Before commencing‚ ensure the gas supply is turned OFF at the source. The Rheem Metro Max 26 requires a specific gas inlet pressure; verify this specification in the technical data section of this manual.
Use a gas-approved pipe sealant on all threaded connections to prevent leaks. Carefully connect the gas supply line to the designated gas inlet on the water heater‚ tightening securely but avoiding over-tightening. After connection‚ conduct a thorough leak test using a soap solution – bubbles indicate a leak.
PAGE 4 provides a visual guide to the gas inlet location. Never attempt to modify or bypass any safety devices connected to the gas supply.
Cold Water Inlet & Hot Water Outlet Connections
Proper connection of the cold water inlet and hot water outlet is vital for the Rheem Metro Max 26’s operation. Use appropriate plumbing fittings and ensure all connections are watertight to prevent leaks and maintain water pressure. The cold water inlet is typically located on one side‚ and the hot water outlet on the other – PAGE 4 illustrates these positions.
Employ Teflon tape on all threaded connections for a secure seal. Before fully tightening‚ flush the lines to remove any debris. Connect the cold water supply line and the hot water distribution pipes‚ ensuring they are adequately supported to prevent strain on the unit.
Regularly inspect these connections for leaks and address them promptly.
Power Lead Connection
Connecting the power lead to your Rheem Metro Max 26 requires careful attention to electrical safety standards; PAGE 27 details the power lead connection process.
