Congratulations! You've just purchased a new Marey Power Gas tankless water heater and will soon begin to enjoy the benefits of “goingtankless.” The availability of instant hot water, combined with the unit's outstanding energy efficiency and space saving design, will quickly convince you that you've made the best decision for meeting your home's hot water needs.
1. Water heater-Qty 1 2. Gas inlet hose connector-Qty 1 3. Rubber gasket-Qty 2 4. Operating Instructions-Qty 16 5. Mounting Screws-4 Sets - Do NOT install the water heater in a sealed room or in a room with poor air circulation. - You MUST install the exhaust pipe to properly discharge the exhaust gases. - Do NOT block the exhaust pipe or the air inlet at any time. This can cause incomplete combustion and can lead to gas poisoning.
6. Anti-dry combustion protection: Should dry combustion occur for any reason, the gas supply will be immediately and automatically shut off. 7. Over-pressure protection: When water pressure is over 145 PSI, the unit will automatically relieve the excessive pressure to avoid damage to its internal components. PRECAUTIONS: 1. The water heater must be installed in a well-ventilated area.
Hot Water Outlet - The hot water outlet joint is 1/2”NPT pipe thread. Washer 25" 29" Nut Expansion Screw 18" Heater Case - The hot water outlet should be connected by flexible tubing or rigid PVC of the type intended for use with hot water. - The inner diameter of the water outlet pipe (including the valve) shouldn´t be less than 3/8”. Larger diameter pipe is acceptable as long as the appropriate adapters are used.
- ALL jurisdictions in North America allow for Z-Vent material to be used for venting tankless hot water heaters. The condensation of a tankless water heater is slightly more acidic than that of a standard water heater. Z-Vent is double walled stainless steel vent pipe made specifically for venting tankless heaters. Z-Vent is intended for lifetime use and will never corrode or rust. - Z-Vent material is available at most home improvement stores, and can be found at many online retailers as well.
- Start the gas supply. Check again for gas leaks using soapy water and correct as necessary. 1. If a gas leak is detected at any time, close the main gas valve immediately. The Marey service center or your local gas company should be contacted for repair. - Open the hot water faucet. You should hear the ignition clicking, and hot water should begin flowing. Sometimes, if there is air in either the water or gas supply lines, you will not get immediate combustion.
