With the power off, you can check the continuity through the surge protector. Place a meter lead on the
top pin #1 of the surge protector and pin #3 on the bottom of the surge protector. Check across the top
pin #3 and the bottom pin #1. If you read continuity across these two points, the surge protector is good.
If you do not get continuity, replace the surge protector.

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.
