Connection Water of the Supply and Hot Water Outlet
The cold water inlet and the hot water outlet are connected via 2 standard ½” male fitting. Use a
rubber seal or other removable sealants. Piping and components connected to the heater shall be
suitable for use with potable water.
When tightening water connections to the water line, be sure to back up the fittings with a wrench as to
not damage the copper water tubing. Re-tighten the compressions nuts on the water fittings.
With the power and gas supply to the heater turned off, pressurize the water system, purge off all air and check for
leaks.
The water heater is controlled and started by the water flow. If the water flow is higher than 1.5 l/min,
the burner starts automatically and heats up the water to the desired temperature.
