Section V-5054 - Controls

A. Each individual automatically-fired potable water heater, in addition to the operating control used for normal water heater operation shall have a separate high limit temperature actuated combustion control that will automatically cut off the fuel supply. The temperature range of the high limit temperature actuated control shall not allow a setting over 210° F.

1. On gas-fired water heaters, the high limit temperature control when actuated shall shut off the fuel supply with a shut off means other than the operating control valve. Separate valves may have a common body.

2. On electrically-heated potable water heaters, the high limit temperature control when actuated shall cut off all power to the operating controls.

3. On oil-fired potable water heaters, the limit temperature control when actuated shall cut off all current flow to the burner mechanism.

B. All potable water heaters shall be equipped with suitable primary (flame safeguards) safety controls, safety limit switches, and burners, or electrical elements as required by one of the following nationally recognized standards:

1. ANSI/UL 732 Standard for Safety Oil-Fired Water Heaters (UL 732);

2. ANSI Z 21.10.3 American National Standards for Gas Water Heaters, Volume III, Circulating Rank, Instantaneous and Large Automatic Storage Type water Heaters;

3. Underwriters Laboratories Inc. UL 795. Standards for Safety, Commercial-Industrial Gas-Heating Equipment;

4. Underwriters Laboratories Inc. UL 1453, Standards for Safety, Electric Booster and Commercial Storage Tank Water Heaters.

C. The symbol of the certifying organization which has investigated such as having complied with a nationally recognized standard shall be affixed to the equipment and shall be considered as evidence that controls and heat generating apparatus were manufactured in accordance with that standard. (A certifying organization is one that provides uniform testing, examination, and listing procedures under established, nationally recognized standards and that is acceptable to the jurisdiction.)
