DOMESTIC HOT WATER
The Domestic Hot Water Flat plate Kit consists of a Water to Water Heat Transfer unit and the fittings needed to hook it
up. The unit goes on top of the domestic hot water heater and is connected as shown below.
EXISTING FORCED AIR
A water to air heat exchanger is inserted in the existing plenum. In most cases the heat exchanger is placed in a
horizontal position, keeping all four sides level. The air must be forced through the finned area of the heat exchanger
evenly. The hot water line coming from the hot - water tube enters the bottom fitting of the heat exchanger and exits
the top fitting, which returns to the furnace. If the plenum is too large or too small, it must be altered to fit the heat
exchanger properly.
After installation of the add-on water to air exchanger, the air flow must be increased to fuel the furnaces, electric
furnaces, and electric/gas furnaces. Methods of doing this are:
BELT DRIVE SYSTEM:
Blower pulleys and motor pulleys may be changed but the electric current flowing through
the motor shall not exceed the nameplate rating. (A blower motor or larger power may be used.)
DIRECT DRIVE SYSTEM:
The motor shall not be changed, however the speed of the motor may be increased.
Water return to
Crown Royal Stove
Hot Water from
Crown Royal Stove
THE HEAT EXCHANGER:
Air blows through the heat exchanger’s grill taking the heat from the water heated grill and
blowing it into your existing ductwork.
CAUTION!!!
When installing heat exchangers do not tamper with existing controls. Wiring to existing blower can
be done with a line voltage or low voltage thermostat.
NOTE:
Wire thermostats according to directions provided by the manufacturer.
