PLUMBING - INSTALLATION
SYSTEM CONFIGURATIONS
The WinterGreen High Efficiency Hydronic Furnace can be plumbed to accommodate a variety of appli-
cations. The high temperature fluid transfer of the furnace can supply heating to all types of fluid based
systems for your home, outbuildings, swimming pools and spas etc. There are many different applica-
tions that can applied to your furnace, this manual shows only 2 basic configurations of many available.
See your WinterGreen representative for information regarding your specific application.
There are 2 (two) basic system configurations that the furnace can be setup for: An “Open System” or a
“Closed System”.
An
“Open System” configuration is when the circulating system is open to the atmospheric pressure.
WinterGreen does not recommend “Open Systems” for indoor use.
A “Closed System” configuration is when the circulating system is closed and sealed from atmospheric
pressure.
WinterGreen recommends that it better to use a closed loop system when setting up the furnace. The
advantages with a closed loop system are:
Reduced Iron-Oxidization caused by air in the system. Iron – oxide leaves deposits that clog metal
components such as valves and heat exchangers.
When pressurized – produces higher boiling points.
A healthier environment.
It is best to check with local authorities before installing a Closed System, as some local codes require
ASME certification for closed pressurizes systems. The WinterGreen furnace is not ASME (American
Society of Mechanical Engineers) rated. If local codes restrict this configuration, the furnace can setup
for an Open System.
Filling the System :
The WinterGreen Furnace uses Propylene Glycol (Safe for humans) mixed with water as a heat
transfer fluid. Do not confuse this with Ethylene Glycol (Highly toxic) which is commonly used in automo-
tive applications.
DO NOT USE ETHYLENE GLYCOL IN THE FURNACE. Fill the system using a fluid
transfer pump connected to the “System Fill/Drain valve located below the circulation pump which has
connection threads to accommodate a fill hose from the pump. (See Plumbing Installation “Closed &
Open System Configuration” drawings on the following pages).
NOTE: The WinterGreen Hydronic Furnace can be installed to operate as an independent heat source
or be used as an add-on to the homes existing heating system. If the furnace is to be used in combina-
tion with an existing system, the system must be thoroughly inspected prior to installation and meet all
local codes and safety standards. The installation must have any required controls which are in accor-
dance with the appropriate specified standards of NFPA (National Fire Protection Association).
NOTE: Installation of The WinterGreen Hydronic Furnace must comply with all regulations,
codes and minimum installation clearances that have been stated in this manual and by authori-
ties having jurisdiction over this type of appliance.
RISK OF HOT FLUID BURNS
The WinterGreen Hydronic Furnace can produce very hot fluid
(185˚F+). Extreme care should be taken not to come in contact with
the system fluids while the furnace is in operation.
DO NOT WORK ON THE FURNACE OR COMPONENTS WHILE THE FURNACE IS IN OPERATION.
