Hot water supply and kitchen boiler connections : a text book on the installation of hot water service in residences and other buildings and methods of connecting range boilers, steam and gas water heaters. over a per-forated cone, through which it passesexposed to the intense heat from theBunsen burners and so down over thelower part of the shell which is in theform of a frustum of a coneto the outlet tube. When more than one fix-ture is to be served a goose-neck or offset is provided sothat an open end can be main-tained to safeguard theheater. A valve can be fittedto the other outlet so thatwater can be drawn freely,without the necessity of run-ning any through the openend to the other fixtures. Aby-pass or pilot light is ar-ranged so that it must beturned on and lighted before the main gas valve is opened, thusinsuring that gas will not collect in the casing before the lightis applied. The water supply valve is also arranged so thatthe lever must be automatically turned up by the action ofopening the gas valve. The whole heater is placed on a white enameled iron shelfsupported by a bracket. The Bunsen burners are readily re-moved for cleaning when necessary. A pipe must be connected. Fig. 86.

When takento the open air a hood should be fitted so that down draughts willbe prevented, but the vent should enter a heated flue wheneverpossible. The second type, the simple kitchenboiler heater, is of a different construc-tion to the type just described. Herethe water is circulated as it is heated to astorage tank, from which it is drawn asrequired. The heater generally consistsof a coil of copper pipe, as shown in , or a series of hollow discs connectedby short pieces of pipe which presentsa comparatively large heating surface tothe effect of a hot Bunsenflame produced
