WARNING

All boiler builds, except boilers bearing the UL Label, are suitable for installation on combustible floor. Do not install boiler on carpeting.

Floor construction should have adequate load bearing characteristics to bear the weight of the boiler filled with water (see Table 1). A boiler foundation similar to the one shown in Figure 2 is recommended if the boiler room floor is weak or uneven or if a water condition exists.

4.PROVIDE AIR SUPPLY AND VENTILATION to accommodate proper combustion.

WARNING

Failure to supply adequate air to the boiler will result in unsafe boiler operation.

For commercial and industrial equipment, permanent facilities for supplying an ample amount of outside air shall be provided in accordance with the following.

For boiler rooms adjacent to outside walls, and where combustion air is provided by natural ventilation from the outside, there shall be a permanent air supply inlet having a total free area of not less than 1 sq. in. per 4,000 Btu per hr. (35 sq. in. per gal. per hr.) (5.5 cm2 per kw.) of total input rating of the burner or burners and in no case less than 35 sq. in. (0.425 m2).

For boiler rooms not adjacent to outside walls, the combustion air shall be supplied in a manner acceptable to the authority having jurisdiction.
