PLUMBING - INSTALLATION
NOTE: All plumbing configuration drawings depicted in the “Plumbing Installation” section of
this manual are for illustration purposes. Due to the various safety and control devices that may
be required for individual applications, it is recommended that you consult your WinterGreen
representative for the design configuration that meets your needs.
CLOSED SYSTEM – BASIC CONFIGURATION With a Heat Exchanger in Home Heating Furnace
The “Closed System” is a circulation system that is closed and sealed to atmospheric pressure. This
type of configuration can slightly pressurize the system therefore requires the use of a 30 PSI Pressure
Relief Valve.
The WinterGreen Hydronic Furnace must operate below 15 PSI. This configuration
also shows a heat exchanger mounted in the ductwork of an existing home heating furnace. The use of
an Auto fill and Backflow Preventer keeps the system filled should there be a fluid drop. To protect
against freezing and corrosion a propylene glycol fluid mixture should be used to circulate through the
system. To protect the furnace from condensation and creosote buildup a mixing valve is used to keep
return fluid temperatures above 150˚F. The use of a combination heat exchanger/fan and a solenoid
valve to control the fluid provides Thermal Protection for over heating.
NOTE: The furnace heat exchanger must be mounted on the hot air side of the plenum. DO NOT
install the heat exchanger in the cold-air return inlet of the central furnace. Before installing this
unit as an add on to the existing furnace, a thorough inspection and approval must be made of
the existing systems by a qualified inspector. Any connections to existing ductwork of a forced
air system must comply with NFPA 90B & 2-1.1 and have plenums constructed of metal in accor-
dance with NFPA 90B & 2-1.3. Contact your local H.V.A.C. professional for determining compati-
bility of the WinterGreen Furnace to your existing heating system prior to installation.
