1.GENERAL
19A Series boilers are
The boilers are supplied completely knocked down for field assembly, as factory assembled blocks of sections or completely assembled
The boilers are conservatively rated for high efficiency performance with capability for
2.BOILER LOCATION
The boiler must be installed on a smooth, level, non- combustible floor or pad as close to the chimney or vent location as possible to minimize breeching length. Allow clearance around the boiler for piping, service, maintenance, cleaning and tankless coil removal. Approximately 30 inches on the sides is a minimum (Check local code requirements). Do not install electrical conductors in floor or pad under boilers.
See FIGURE 1 for boiler floor pad requirements, and TABLE 1 for minimum required pad length.

FIGURE 1
In the absence of such local requirements, the following should govern:
A.S.M.E. Section IV - “Heating Boilers"
A.S.M.E. Section VI - “Care and Operation of Boilers” ANSI/NFPA 31 - “Installation of Oil Burning Equipment” ANSI/Z223.1 - “National Fuel Gas Code” ANSI/NFPA 70 - “National Electrical Code”
4.CHIMNEY AND BREECHING
The breeching connection between boiler and chimney should be as direct as possible with the minimum number of elbows or bends. It should pitch upwards to the chimney at a rate of 1/4 inch per foot of horizontal run. Generally, the breeching and chimney should be the same diameter as the boiler outlet connection.
NOTE
11 and 12 section uses adapter collar for connection to 12" diameter vent system.
For fuel conservation and stable burner performance, the vent connection from the boiler should not include a barometric draft control or other opening unless the venting system can develop an excessive draft, or is required by code.
