recommend that a service valve kit be used for the installation as it will reduce
installation costs and make servicing the water heater easier. The Webstone

Ball Valves and Temperature / Pressure relief valves specified in the Typical
Installation Figure above in one convenient easy to install kit.
The heater MUST be installed in a vertical position with fuel gas inlet
at the bottom and exhaust vent positioned at the top. Installation in

local codes).
