□ Tankless water heaters are considered a non-continuous load.
□ If a multiple feed installation is used, it is acceptable to install up to two conductors in
one line side port. Additionally, when a power distribution block is supplied,
additional conductors may be installed in an open load side port of the power
distribution block.
□ Wiring sizing listed is for 75°C THHN. 60°C or 90°C wire may be used. Refer to
NEC table 310.16 for sizing.
□ Conductors should be sized to maintain a voltage drop of less than 3% under load.
□ Electrical specifications for the High Flow (HX) models are the same as listed for the
Low Flow (TX) models.
