The gas vent sizing tables are not applicable to outside (exposed) chimneys or vents below the roofline per NFPA 54. AType B vent lining an exposed masonry chimney is considered to be an enclosed vent system, and these tables may be used. Connectors Single-wall pipe (stovepipe) is not recommended for use in TYPE B venting systems.
The chimney is about 30 feet high. The stove pipes are 6" single wall. The coal boiler enters below the oil boiler and on the opposite side of the chimney. There is no rise to the coal boiler's stove pipe, it enters straight into the chimney and runs slightly down hill.

GAS-FIRED CAST IRON BOILERS FOR NATURAL AND L.P. PROPANE GASES must extend at least 2" beyond the boiler cabinet on all sides. CHIMNEY HEIGHT:15 ft. minimum from draft hood skirt to top of chimney. CHIMNEY INSIDE DIAMETERmust be same as Dimen-sion C or larger. Larger diameter and/or height may be required if
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or
B. The gas supply line to the boiler should be run directly from the meter for natural gas or from the fuel tank for L.P. propane gas. See page 2 for location of union and manual main shut-off valve that may be specified locally. Selecting pipe size for natural gas: 1.Measure or estimate the length of piping from the meter to the installation site.
Base model - Values represent a 1,000,000 Btu/hour gas-fired, hot-water boiler operated for 1,500 full-load hours per year with a thermal efficiency of 80%. The performance of this standard unit is based on ASHRAE 90.1-2007. Thermal efficiency (E t) - Represents a boiler's energy output divided by energy input as defined by ANSI Z21.13. A boiler's thermal efficiency rating should be used to
Provisions are added that address natural gas boilers. References to fuel oil grades #4 and #6 are removed, as relating to the use of such fuels in (13) Chimney height. Chimney height is the distance from the centerline of the entrance of the combustion gases into the chimney to the top of the chimney.
A Chimney is a self standing structure for venting hot gases from a boiler to the outside atmosphere  and to disperse them at a considerable height. 1 Other definition 2 Construction 3 Regulations 4 Chimney draught or draft 5 Remarkable Chimneys (not updated) 6 Other uses 7 External links The word 'chimney' also refers to a system for venting hot gases and smoke from a stove, furnace or
Fuel Gas Fired Appliances Propane and Natural Fuel Gas-fired appliance are vented through the NFPA 211 document and the NFPA 54 (National Fuel Gas Code, 2002 Edition). Both documents discuss the need for restrictive measures when a clay lined chimney is converted solely for gas-fired equipment use. Because gas-fired equipment has lower exhaust gas

The intent of this brief is to provide code-related information about gas-fired boilers to help ensure that the measure will be accepted as being in compliance with the code. Providing notes for code officials on how to plan reviews and conduct field inspections can help builders or remodelers design installations and prepare construction documents, and provide jurisdictional officials with
BOILER STACKS AND CHIMNEYS - Reprinted Courtesy of the National Board of Boiler and Pressure Vessel Inspectors Any boiler using a combustible fuel source requires a stack or chimney. The stack or chimney aids combustion in natural draft boilers by helping to ensure a steady supply of combustion air which mixes with the fuel.
Jun 28, 2011 · I'm about to replace my oil burner with a new gas burner. I have steam heat and a 25-year old boiler, and the exhaust goes up the chimney (all brick, no clay tiles). I understand the importance of getting a chimney liner for gas heat, to avoid CO poisoning.

But many dont realize that a gas heating appliance whether it is a furnace, boiler or even a water heater relies on the chimney for proper venting of the exhaust. Appliances fueled by natural gas or propane may not produce the visible soot that appliances burning other fuels do, but they can deposit corrosive substances in your chimney.
