Access to Water Heaters

Postby daz » Tue Mar 13, 2007 10:55 am

The Plumbing Code Advisory Committee is looking into changing the wording of 4715.2240 and .0100 Subp. 84a. (shown below) The issue is basically how high off the floor can a water heater be that is greater than 6 gallons in capacity. Some would like to allow larger (definable size) water heaters to be safely installed on a properly supported platfom/shelf 6 feet above the floor but not concealed in a ceiling space. Others would like any water heater greater than 6 gallons to only be allowed up to 18 inches above the floor, or have a proper stairs/handrail & guardrail/landing installed for access to installations higher of anything higher than 18 inches above floor.

My thought is that water heaters up to 12 gallons can be installed up to 6 feet in height on a properly supported platform/shelf. Most plumbers think the weight of a 12 gallon W.H. is reasonable to carry up and down a ladder. Perhaps there could be exceptions for larger ones in differing situations. The definition readily accessible may have to be redefined or just removed from 4715.2240 depending on the outcome.

Please share your thoughts and experiences as this issue is coming up soon. These type of scenerios are common in commercial buildings with small mechanical rooms.

4715.2240 Every water heater installation shall be readily accessible
for inspection, repair, or replacement. The appliance space
shall be provided with an opening or doorway of sufficient size
to provide such access.

Exception: A water heater with a tank capacity not greater
than six gallons may be concealed in a ceiling space provided
the water heater has been set in an overflow pan that has been
constructed of a corrosion-resistant material, has side walls
extending at least four inches upward, and has an outlet that
shall not be sized less than the supply line to the water
heater. This outlet shall be piped undiminished in size to a
point of safe disposal below the ceiling area. No tools shall
be required to gain access to a water heater.

4715.0100 Subp. 84a. Readily accessible. "Readily accessible" means
capable of being reached safely and quickly for operation,
repair, or inspection without requiring those to whom ready
access is requisite to remove obstacles, panels, or similar
obstructions.

As of now, we would allow any size water heater to be installed on a platform as long as it is not above the ceiling. 6 gal. or less above. I would be in favor of establishing a limited size to be mounted on a shelf greater than 18" and possibly even a height limitation for these. Anything greater than this size to be 18" or less above the floor. This appears to make sense.
