The following rules and regulations shall apply to the City Gas Department relating to installation of gas- fired heating units.
(A) All gas conversion burners installed in the territory served by the Department shall be A.G.A. certified and all designed heating plants shall be A.G.A. approved.
(B) Conversion burners shall be properly sized to a heating plant being converted.
(C) No conversion burner shall be installed in old or inefficient warm air furnaces which either are in poor repair or have inefficient flue travel or old or leaky boilers which are in poor repair or have short flue travel.
(D) A test for leakage by use of oil of wintergreen shall be performed on any warm air heating plant before installing a conversion burner. A furnace must be reset if found to be leaking.
(E) All soot and scale shall be removed thoroughly from a heating plant to be converted.
(F) The chimney to which a heating plant stack pipe will be connected shall be cleaned.
(G) The manufacturer's recommendations for the installation of gas conversion burners or designed heating plants shall be followed and all parts shall be checked before installation.
(H) A conversion burner shall be installed so all secondary air can be controlled.
(I) The installer shall either remove or permanently fix in the wide open position any damper in the flue neck of a heating plant being converted.
(J) A new stack pipe shall be installed with an approved design and size draft diverter to clean the unobstructed chimney. The stack pipe size shall be one square inch in area per 7,500 BTU of maximum burner output.
(K) A draft diverter shall be located in an almost horizontal position, with the unobstructed clearance as high as the highest flue passage. Designed heating plants may have built-in diverters.
(L) The stack pipe shall be installed so as to maintain a uniform rise of at least 1/4 inch per foot of horizontal run. Sharp turns with the stack pipe shall be avoided. The stack pipe joints shall be secured with metal screws and supports to prevent sagging.
(M) Heating plants of the down-draft type shall be vented by connecting a one-inch black steel pipe from the highest point of the flue passage of the heating plant to the stack pipe. The one-inch steel pipe shall be welded or screwed into the furnace in such a manner as to ensure no leakage.
(N) The gas fuel line shall be of an adequate size to support a three-inch burner pressure with the burner operating at the required BTU input.
(O) The gas burner fuel line shall originate at a tee as near as possible to the gas meter and ahead of all other appliances and shall be so supported that no weight or strain shall be conveyed to the gas meter or the gas burner manifold.
(P) A gas shutoff valve shall be installed in the gas fuel line within two feet of the gas burner manifold. A pilot line shall be installed ahead of the main shutoff valve and controls.
(Q) A fused-type switch shall be installed in the line ahead of the controls and all electrical devices on all gas heat installations.
(R) All electrical wiring shall conform with the provisions of this code pertaining to electricity.
(S) A high-limit control shall be installed on all heating plants.
(T) A low-water cutoff control shall be installed on all gas-fired steam boilers.
(U) A report of the completion of a gas-fired heater installation shall be made immediately to the Department for inspection and balancing.
(V) Heating contractors shall be required to follow the code of heating standards of installation and shall make any correction to any installation which is deemed necessary by the Department or its authorized representatives.
