tank. The drain pan must be at least
two inches wider than the diameter
of the water heater. Install the drain
pan so the water level is limited to a
maximum depth of 1-3/4".
Verify that the water heater is

set in place properly. Check
that:
• There is adequate space to install
the T&P Relief Valve discharge
pipe and that it can be piped to a
separate drain (and not into the
drain pan).
• There is adequate access and
space around the water heater
for future maintenance.
The water heater is installed ver cally.
