tubing with a compression tting or a exible stainless steel braided hot water supply

[Warning: Do not use plastic tubing. Plastic tubing can deteriorate over time and cause a
leak inside the tube tting.]
You also need a 90° Fitting with
3

sized to t your hot water supply line (copper tubing/compression tting or braided hose)

For the power cable, we recommend a jacketed 12-2 cable with ground. Note that some
local codes may require the cable to have a BX style metal jacket.
