    This "Open Box" product is in excellent condition. Each unit is a fully functional return item with little or no cosmetic blemishes. The product has been tested for quality assurance and is certified "Open Box". Please note that all "Open Box" units include the original manufacturer’s warranty but are not eligible for a “buyer’s remorse” return.

    The Rheem RTG-53PVPOB liquid propane tankless hot water heater supplies 1-2 major hot water applications at a time. Unit can be vented either through the wall or roof and can be connected in series to increase hot water flow. The RTG-53PVOB tankless hot water heater can supply 5.3 gallons per minute of hot water at a 45 degree temperature rise. It requires a 3" stainless steel exhaust vent and utilizes the air within the room where the water heater is installed for the combustion air (note: consult the user's manual to determine if steps need to be taken to ensure the combustion air requirements are met). This tankless water heater carries a 10 year limited warranty on the heat exchanger and a 3 year limited warranty on parts. The ignition is electronic and the unit comes with a 120V power cord.

    This model can be linked with another RTG-53PVOB in series with the EZ-Link cable (RTG-20040) for high demand applications as the two units would operate as one with double the water flow. When 3 to 20 units are connected in series a manifold controller, cables and/or control boards are required.

    The RTG53PVPOB tankless hot water heater model differs from the RTG53DVP in that it has an internal combusion air setting and does not require a 2nd hose to pull air from the outside.

    This model only accepts 3/5" concentric stainless steel venting.

    • 90º F rise at 2.6 gpm
    • 80º F rise at 3.0 gpm

    • 60º F rise at 3.9 gpm
    • 50º F rise at 4.7 gpm
