PB Heat LLC Boiler Manual: Installation and Combustion Air Guidelines
Page 7

PREINSTALLATION

c.Each of the appliances served shall be interlocked to the mechanical air supply to prevent main burner operation where the mechanical air supply system is not in operation.

d.In buildings where the combustion air is provided by the mechanical ventilation system, the system shall provide the specified combustion air rate in addition to the required ventilation air.

8.Louvers & Grills:

a.The required size of openings for combustion, ventilation, and dilution air shall be based on the net free area of each opening.

i.Where the free area through a louver or grille is known, it shall be used in calculating the opening size required to provide the free area specified.

ii.Where the free area through a louver or grille is not known, it shall be assumed that wooden louvers will have 25% free area and metal louvers and grilles will have 75% free area.

iii.Nonmotorized dampers shall be fixed in the open position.

b.Motorized dampers shall be interlocked with the equipment so that they are proven in the full open position prior to ignition and during operation of the main burner.

i.The interlock shall prevent the main burner from igniting if the damper fails to open during burner startup.

ii.The interlock shall shut down the burner if the damper closes during burner operation.

9.Combustion Air Ducts

a.Ducts shall be constructed of galvanized steel or an equivalent corrosion- resistant material.

b.Ducts shall terminate in an unobstructed space, allowing free movement of combustion air to the appliances.

c.Ducts shall serve a single space.

d.Ducts shall not serve both upper and lower combustion air openings where both such openings are used. The separation between ducts serving upper and lower combustion air openings shall be maintained to the source of combustion air.

e.Ducts shall not be screened where terminating in an attic space.

f.Horizontal upper combustion air ducts shall not slope downward toward the source of the combustion air.

g.The remaining space surrounding a chimney liner, gas vent, special gas vent, or plastic piping installed within a masonry, metal, or factory built chimney shall not be used to supply combustion air.

h.Combustion air intake openings located on the exterior of buildings shall have the lowest side of the combustion air intake opening at least 12 inches (305 mm) above grade.

WARNING

Liquefied Petroleum (LP) is heavier than air and may collect or “pool” in a low area in the event of a leak from defective equipment. This gas may then ignite, resulting in a fire or explosion.

D.INSTALLATION SURVEY

For new and existing installations, a Water Installation Survey is available from PB Heat, LLC. The survey will provide information on how a hot water boiler works with your specific system and will provide an overview of hot water system operation in general.

You can also use this survey to locate system problems which will have to be corrected. To obtain copies of the Water Installation Survey, contact your Peerless representative or download it from PeerlessBoilers.com.

E.PLANNING THE LAYOUT

Prepare sketches and notes of the layout to minimize the possibility of interferences with new or existing equipment, piping, venting and wiring.
