Combustion air & vent piping installation

Vent piping

1.Each boiler requires an individual vent pipe, in- stalled and terminated per the Ultra Boiler Manual and Ultra Boiler Venting Suppments.

2.The vent pipes of multiple boilers must terminate on the same side of the building as their air inlet piping, and per all requirements of the Ultra Boiler Manual and Vent Supplements.

Combustion air manifolds

1.When combustion air supplied from a common air manifold pipe as in Figure 12, size the common air duct and louver free area from the minimum free area given in Figure 1, pages 4 and 5.

2.All joints must be sealed.

3.The air inlet must be located:

at least 3 feet below any vent located within 10 feet.

Combustion air piping

1.Provide combustion air piping to each boiler, fol- lowing all requirements for installation and termi- nation per the Ultra Boiler Manual and Ultra Boiler Venting Supplements.

2.Combustion air piping can be supplied from a common combustion air manifold, installed and terminated as shown in Figure 12, below.

the louver bottom must be 12 inches above grade or above the snow line.

4.Compensate for louver blockage when calculating free air openings. Refer to manufacturer’s instruc- tions for size. If unknown use:

a.Wood louvers — 20-25% free area.

b.Metal louvers or grilles — 60-75% free area.

5.Lock open louvers or interlock with boiler controls to open automatically with boiler operation.
