c) Stand two of the legs up along the short side the top on the outside of the top. Fasten the
cross braces through the legs and tighten all bolts. Repeat for the other side.
d) Assemble the long side braces to the legs and themselves.
Place the tank stand on a level floor in its proper location before setting the boiler on top. If the
floor is not level be sure to level the stand by inserting metal shims under the tank stand legs.
Once the boiler is positioned on the stand do not attempt to move the stand.
F) Pipe and Flange Leg Mounting. The boiler base is suplied with two holes at each corner.
Circulator flanges may be installed at each corner under the base using the holes in the base and
the flange bolts. Use four sections of pipe of the same length, thread at each end and screwed into
the flanges at the four corners to create legs. Finish the stand by installing flanges at the ends of
the threaded pipes and securing the flanges to the floor usng fasteners appropriate for the floor.
The boiler may be leveled by screwing the pipes into or out of the flanges prior to securing the
flanges to the floor.
V. AIR FOR COMBUSTION AND VENTILATION - CHIMNEY VENT APPLICATIONS
The unit must be installed where provisions exist for combustion and ventilation air. Ordinarily,
provisions may be furnished by the following methods.
A) Utility Room or Closet
In buildings of tight construction, including most modern homes, you should provide an opening,
connecting to a well ventilated attic, crawl space or directly with the outdoors. The opening should
have a minimum free area of 1 square inch per 1,000 Btu per hour of total input for all appliances in
the enclosure and should terminate below the burner level. Boilers installed in confined areas or closets
must have two ventilation openings in the closet door. Each opening should have a free area of not less
than 1 square inch per 1000 Btu (140 square inch per US gph) of the total input for all appliances in
the enclosure. One opening located near the top of enclosure and one near the bottom.
B) Basement
1. When a boiler is installed in a full basement, infiltration is normally adequate to provide air for
combustion.
2. In buildings of tight construction when the basement windows are weather stripped, one opening to
a well ventilated attic or with the outdoors should be provided. (See part A for opening requirements)
