1. An adaptable water manifold for a swimming pool or spa heater, comprising:
an inlet, the inlet being positioned at an inlet position when the adaptable water manifold is mounted to the gas heater;
an outlet, the outlet being positioned at an outlet position when the adaptable water manifold is mounted to the gas heater;
an inflow section in fluidic communication with the inlet and configured to provide water to one or more heat exchanger tubes;
an outflow section in fluidic communication with the outlet and configured to receive water from one or more heat exchanger tubes;
an inlet fitting having an inlet fitting inlet in fluidic communication with an inlet fitting outlet, the inlet fitting being connectable to the inlet with the inlet fitting outlet adjacent the inlet; and
an outlet fitting having an outlet fitting inlet in fluidic communication with an outlet fitting outlet, the outlet fitting being connectable to the outlet with the outlet fitting inlet adjacent the outlet,
wherein when the inlet fitting is connected to the inlet, the inlet fitting outlet is at the inlet position and the inlet fitting inlet is at an adjusted inlet position, and when the outlet fitting is connected to the outlet, the outlet fitting inlet is at the outlet position and the outlet fitting outlet is at an adjusted outlet position,
