8 Zone Condensing Boiler Panel w/DHW
These stand alone panels work with most condensing boilers. The Type 3 panel provides primary, secondary, and
DHW circulators. Both panels include a 1-1/4" primary loop with air remover and expansion tank connection (no tank) as well
as optional auto-fill assembly. All circulators are energy-saving 3 speed models, which enables the installer to adjust flows
for optimal temperature drops. The entire panel is enclosed in a powder coated steel enclosure for a professional, appliance
style appearance. The 1-1/2" stainless steel distribution manifold is equipped with thermal actuators on each circuit, and can supply up
to 4 gpm to each separate zone. Each zone has a balance valve and flow meter for precise flow balancing. A pressure
differential bypass eliminates velocity noise and helps extend the life of the system components.
Standard equipment includes:
1-1/4" copper primary and secondary piping, 1" copper DHW piping
Primary, secondary, and DHW circulators, pre-wired and tested
High performance 1-1/4" micro-bubble air remover with expansion tank connection (tank not included) including a 10 ft
piece of 3/8" Onix for mounting tank outside of enclosure
Isolation valves for easy servicing of circulators and easy air purging
Spring check valves in primary loop and DHW piping
0-50 psi/60-320 ?F gauge
1-1/2" stainless manifold with thermal actuators, balance valves, flow meters and pressure differential bypass
Manifold adapters are required to transition to the distribution piping. PEX, PAP, copper or Onix can be used for distribution
from the panel to the radiant zones. Order manifold tube adapters separately.
The panel circulators are controlled by the boiler via field wiring. Outdoor reset, DHW priority and other features are
dependent on the boiler control.
Maximum flow rate is approximately 22 gpm. Each Watts Radiant 2699 circulator is capable of providing approximately 15
gpm at 20 ft hd on high speed.
