4.5 Installation
WARNING: Use industry standard safe rigging methods, such as including the use straps and spreader
bars and lifting from the water heater base skid assembly, when attempting to lift or move this product.
Failure to follow industry safe rigging methods could result in property damage, serious injury or death.
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 back-up wrench
on tank nipples when tightening unions, valves, etc.
6. Insulate hot water and return circulation lines. Insulate cold water supply lines if subject to freezing during
shutdown periods. IMPORTANT: Do not use the plumbing connected to the appliance as a ground for
welding or any other purpose.
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.
8. Pipe the drain valve to a suitable open drain.
WARNING: All system piping to the heat exchanger plumbing must be adequately supported. Failure to
provide adequate support will result in excessive loads on the heat exchanger connections that can cause
hot water or steam discharge resulting in property damage, scalding and personal injury or loss of life.
4.6 Service Clearances
Allow sufficient space to provide adequate clearances on all sides for service and inspection. Recommended
clearance is 24” at the top and front, 18” at left and right sides of the appliance. Optional equipment may increase
the clearance requirements. Allow sufficient space for installing and servicing connections such as water, electrical,
pump and other auxiliary equipment.
5 GENERAL GUIDELINES
5.1 Water Inlet / Outlet Connections
Important: Do not use galvanized or steel pipe nipples when making waterside connections. Use non-ferrous
nipples only.
Make inlet and outlet water connections directly to the threaded bolt-on bronze tank flanges. Over tightening
connections to the flanges may cause damage to the flange or tank and are not covered by warranty. For ease of
service, install unions on inlet and outlet piping to the unit. Do not use galvanized nipples to make tank connections
as these will cause corrosion and rust. Piping and components connected to the water heater must be suitable for
potable water, for the water temperatures they will experience and for their application.
CAUTION: Flush all water supply lines before connecting the unit.
