HYDRONIC DISTRIBUTION SYSTEMS.
10-11.1
Pumps. Provide [inline] [base mounted] centrifugal pump for each hydronic system
provided. Provide flexible connections and pressure gauges on pump inlet and outlet. [Provide
primary and backup pump for each hydronic system provided.]
10-11.2
Air separator. Provide air separator for each closed hydronic system provided.
10-11.3
Expansion. Provide a [bladder tank] [expansion tank] for each closed hydronic
system provided.
10-11.4
Chemical feed systems. Provide means for chemical treatment for each hydronic
system provided. Provide automatic chemical treatment systems for all open water systems.
Provide initial treatment and one year supply of chemicals for each system provided.
10-11.5
Makeup water. Provide backflow preventers and pressure reducing valves on each
makeup water system provided. Each hydronic system shall have a separate pressure reducing
valve.
10-12
bays. [A hanging reel type system is preferred.] Provide welding exhaust systems in all areas
designated for welding.
10-12.1
Vehicle exhaust. Provide a [hanging exposed overhead] [hanging disappearing
overhead] [disappearing underfloor] [nondisappearing (plug-in underfloor)] type vehicle tail pipe
exhaust system. Construct and install in accordance with applicable requirements of NFPA 91.
10-12.1.1 Fans. Fans shall be centrifugal type. [Provide unit of all welded construction, utilizing
minimum 14-gage carbon steel in AMCA Class II construction.] [Internal and external protective
coating shall be manufacturer's standard, engineered quality type, with properties comparable
to [air-dry or baked phenolic,] [or] [epoxy] applied in multiple coats of 0.10 to 0.15 mm dry film
thickness.] [Mount entire assembly for vibration isolation on structural steel base and spring or
elastomer type isolators with minimum transmissibility of [10] [5] percent.] [Provide split sleeve
or flexible connection at fan inlet.]
10-12.1.2 Ducts. Construct ducts and miter or stamped fittings with galvanized steel. Duct
sheet metal gages shall conform to Class I in SMACNA RIDCSTD and SMACNA RIDCS.
Construct suction side ductwork with lock groove seam longitudinal joints. Connect
circumferential joints between sections with push-on or bead and crimp type, secured with a
minimum 4 rivets or screws on ducts up to and including 100 mm diameter, and with screws or
rivets a minimum 80 mm on center on larger sizes of duct. Lap joints in the direction of air flow.
On disappearing overhead systems, assemble roller duct sections using pop rivets. Solder all
joints or construct ductwork leak-tight as for discharge side ductwork below. Construct ductwork
on the discharge side of the fan leak-tight with joints and seams welded, brazed, or soldered.
Provide flanges with suitable gaskets, where required. Repair damaged galvanizing with
galvanizing repair compound.
10-12.1.3 Flexible Tail Pipe Exhaust Tubing and Connectors. Provide interlocking helical seam
metallic type construction of 0.3 mm minimum thickness up to and including 150 mm diameter
