8.Do not install on carpet or other combustible floor coverings. If installation over a combustible floor is required, follow these guidelines:

−Use a base of hollow clay tile or concrete blocks from 8" to 12" thick and extending 24" beyond the sides.

−Place the blocks in line so that the holes line up horizontally to provide a clear passage through the blocks.

−Install 1/2” fireproof millboard with a 20-gage sheet metal cover over the block base.

−Center the unit on the base. Also follow this procedure if electrical conduit runs through the floor, and beneath the appliance. A field-installed base must meet all local fire and safety code requirements.

4.5Service Clearances

Allow sufficient space to provide adequate clearances on all sides for service and inspection. At least 24” above the water heater is required for filter replacement and burner/gas control service, 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, gas, vent, combustion air, electrical, pump and other auxiliary equipment.

4.6Clearances To Combustible Surfaces

Minimum 1” clearance must be provided from any vent surface to adjacent combustible material. The minimum clearances to unprotected combustible material are 24” be provided at the front, 8” be provided at the rear and 8” at top, left and right sides of the appliance.

5 GENERAL PIPING GUIDELINES

5.1Inlet and Outlet Connections

1.Use only non-ferrous water piping and fittings. Do not use galvanized pipe or fittings. Use of ferrous or galvanized pipe or fittings can cause rust to form.

2.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.

3.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.

4.Pipe the drain valve to a suitable open drain.

5.2Building Return Piping

To maximize water heater efficiency, connect the building return (≈ 5 gpm) directly to the return fitting located at the rear of the tank.
