Procurement Notes

FAQs

What should a contractor verify before ordering Rheem RRTGHS10I700189?

Verify the old unit nameplate, available space, Natural Gas, Propane service, water-connection size, local code, and any venting or electrical requirements before treating it as a direct replacement.

What jobsite details help Super Arbor quote this correctly?

Send the model being replaced, install photos, site ZIP code, quantity, delivery window, access limits, and whether liftgate, scheduled delivery, or multi-unit staging is needed.

How should 10.1 gpm be used in sizing?

Use it as a planning signal, then confirm against fixture count, tenant demand, recovery/flow needs, incoming water temperature, and local code rather than matching only the old tank size.

What utility or install constraint matters most for this tankless water heaters?

Confirm Natural Gas, Propane and 120V / 132 W; for tankless models also confirm B-Vent, condensate handling when applicable, gas-line capacity, and termination location before purchase.

Why keep this as a draft sample before activating it?
