9.3 Choosing an Installation Location
When choosing an installation location, you must ensure that
the location provides adequate clearance for the water heater,
adequate venting and drainage options, and sufficient access to
gas, water, and electrical supplies. Before proceeding, read the
water heater installation manual.
●
Choose an outside wall for the installation. Installation on a wall
protected by an overhang above is recommended.
●
Size the water and gas connections according to the instructions
in the water heater installation manual. Use unions when
connecting both water lines and the gas supply line to the
heater.
Install the water heater in an area that allows for service and
maintenance access to utility connections, piping, filters, and traps.
Based on the installation location, allow for the following minimum
clearances from the water heater:
