AUTOMATIC INSTANTANEOUS WATER HEATER
A large copper coil using gas as a fuel, surrounded by a cast-iron or steel jacket and equipped with either thermostatic or water value control, and not connected with a tank, range boiler or other storage tank, the water supply coming directly from the house piping and delivering through the hot water piping system.
AUTOMATIC STORAGE WATER HEATER
A tank in which service water, heated by a tank heater or base burner, is stored and the temperature of which is controlled by a thermostat that actuates the fuel valve.
DEPUTY
A deputy inspector or some other properly authorized representative of the inspector.
GAS
Either a manufactured city gas or other gas used for heating purposes, such as propane, pyrofax and butane, usually distributed in containers for use in rural districts.
GAS CONVERSION BURNER
Any type of gas burner which with thermostatic control is used to create steam or heat hot water or air in connection with an existing heating boiler or heating furnace.
GAS HOUSE HEATING BOILER
A cast-iron or steel sectional boiler of either the steam or hot water type using gas as a fuel.[1]
GAS HOUSE HEATING FURNACE
A furnace of the general hot air type using gas as a fuel.
INSPECTOR
The plumbing/mechanical inspector of the city.[2]
INSTALLATION
The original or subsequent placing, equipping or connecting of apparatus.
SERVICE WATER
Hot water heated by any fuel to be used for any purpose except power or heating.
TANK HEATER
A copper coil through which water is heated, the coil being surrounded by a cast-iron or steel jacket.
TANK OR RANGE BOILER
Any vessel of any type or construction used to store heated service water in which hot water may be confined to or subject to a pressure of fifteen (15) pounds or more per square inch pressure above atmosphere, except any pressure vessel used for generating or storing steam or hot water for the purpose of power or heating and except any boiler as defined in R.I.G.L. § 28-25-1.

§ 235-2 Compliance required; permit required. [1]

No tank heater or automatic storage water heater shall be installed unless such tank heater and any tank or range boiler used in connection therewith or such automatic storage water heater is constructed and equipped in compliance with the provisions of this chapter, nor unless a permit for such installation shall first have been secured from the inspector, nor shall the same be placed in service until approved by him or her.

§ 235-3 Restrictions upon installation of tank or range boilers. [1]

No tank or range boiler shall be installed for use on a working pressure greater than forty-two and one-half percent (42 1/2%) of the tested pressure stamped on the tank or range boiler by the manufacturer, nor if solder which fuses at a temperature below six hundred degrees Fahrenheit (600° F.) has been used to hold the tank or range boiler together and not merely for the purpose of making it watertight, nor if solder is used in its construction, unless such solder will not become weakened beyond the normal strength of the material of which the shell and heads are constructed, when subjected to a temperature up to three hundred degrees Fahrenheit (300° F.), nor shall it be installed in any event unless it has been tested to at least two hundred (200) pounds per square inch hydraulic pressure and bears the name of its manufacture and his or her stamp showing at what hydraulic pressure per square inch it has actually been tested.

§ 235-4 Temperature relief valves or fusible plugs on tanks or range boilers.

A. 
No tank or range boiler connected with any water supply system except a gravity system opened to the atmosphere or a tank in which water is heated by steam at a temperature not exceeding two hundred fifty degrees Fahrenheit (250° F.) by means of a pipe or coil located within such tank shall be installed unless it is equipped with a temperature relief valve or fusible plug, with a discharge opening extended to a suitable drain, which will prevent the temperature of the water in the top of the tank or range boiler from exceeding two hundred fifty degrees Fahrenheit (250° F.), such valve or plug to be located in the hot water outlet pipe between the heater and the tank or range boiler, provided that such pipe is not less than three-fourths (3/4) inch in diameter, or in the top of the tank or range boiler or in the hot water outlet connection in a fitting which is directly connected to the top of such tank or range boiler.
B. 
Such temperature relief valve or fusible plug may be located directly in the tank or range boiler at a point not more than six (6) inches above or below the center between the top and bottom in which case the fusible plug must prevent the temperature of the water in the central portion of the tank or range boiler from exceeding two hundred twelve degrees Fahrenheit (212° F.).

§ 235-5 Pressure relief valves in service water heating systems. [1]

No service water heating system equipped with a reducing valve or check valve in the cold water line supplying a tank or range boiler or a check valve embodied in the water meter supplying a tank or range boiler shall be installed unless, in addition to the temperature relief, it has a pressure relief valve located at a point where it will relieve the pressure within the tank or range boiler when and if such pressure exceeds seventy-five (75) pounds per square inch hydraulic pressure.

§ 235-6 Temperature or pressure reliefs required on tank or automatic storage water heaters. [1]

No tank heater or automatic storage water heater shall be installed unless such tank heater or automatic storage water heater or the tanks or other apparatus connected therewith shall be provided with a temperature relief and a pressure relief in accordance with the regulations contained in §§ 235-4 and 235-5, except as therein otherwise provided.
