317 240 5662 Installation Ins GAS-FIRED WATER OR STEAi'1 30ÎLER Cancels: 39234D23 NOTE: THESE INSTRUCTIONS MUST BE LEFT ON OR NEAR THE BOILER. The Model 234 is a low-pressure» sectional, cast-iron water and steam boiler. The design is certified by A.G.A. for use with natural, and propane gases. It is tested for a maximum working pressure of 100 psi on water and 15 psi on steam in accordance with ASME standards for cast-iron boilers. The boiler is available as a Type GW ■ Gravity, Type PW - Circulation Pump, Type CW - Coil Circulation Pump, and Type S - Steam. All boilers are factory assembled. All installations are subject to codes established by local utilities or other authorities having jurisdiction. This jurisdiction normally covers electrical wiring, gas piping, flue specification, and insulation of adjacent combustible material where required clearances cannot be maintained. As a practical guide, use the American National Standard Installation of Gas Appliances and Piping Z21.30, and Bryant Form No, 39003D1 “Procedure for Gas Appliances”. Read these instructions completely before beginning the installation. A70É35 Figure 1 ,, Jlfl |.|lU«i MAW. ..All UIIM • a." JiNJ'il-lf 'JLU.Lt.
