Frost Protection:

This unit has frost protection heaters mounted at different points to protect the water the water heater
from freezing. The heaters located on the hot water outlet line should have a resistance reading of 180-
207 ohms through each of these heaters. The heater located on the heat exchanger piping should have
a resistance reading of 156-180 ohms, and the one located in the water flow sensor valve should have a
resistance reading of 24-28 ohms.

Amp Fuses:

This unit has two inline three-amp glass fuses. Remove the fuse and check continuity through it. If you
have continuity through the fuse, it is good. Otherwise, the fuse is blown and must be replaced.
