1. Check the data decal on the heater. Be sure the electrical supply is adequate for the installation.
2. Carefully remove all shipping supports and bracing.
3. Do not attempt to move or lift heater by the plumbing connections or heat exchanger. Lift only by the
skid using industry standard safe rigging methods.
4. Provide sufficient clearance in front of heat exchanger to facilitate maintenance and removal. See
“Service Clearances” below.
5. Install shut-off valves and unions on the inlet and outlet water piping for servicing. Use caution when
threading pipe nipples into tank connections to prevent cross threading, or over-tightening. Always use a

7. The water heater is equipped with a temperature and pressure relief valve(s) rated for the input. Pipe the
relief valve discharge to a suitable open drain. The drain pipe may not be smaller than the relief valve
opening and must be secured to prevent it from lifting out of the drain under discharge pressure. Do not
install valves or restrictions in the discharge line.
