Existing Hot Water Heat
A Water to Water Heat Transfer Unit (0020-
052) is used to connect to an existing hot
water boiler system.
Note: Any changes that are made to an exist
-
ing boiler should be done by a qualified
plumber and follow all state and local codes.
Chimney
- The flue pipe to be installed can be a rising chimney or a power vent, as long as the following conditions are
met. The flue gas outlet on the boiler is a standard 6” Pipe.
- Elbows can be used, but T’s are recommended to allow for the cleaning of the flue pipe.
- For every one foot of horizontal pipe three feet of vertical pipe is required on a rising chimney.
- Flue pipe should be insulated. Non insulated sections are not recommenced.
- A draft controller should be used to allow proper flow. The draft controller must be installed as close to the
boiler as possible.
- A draft inducer may be used to ensure proper draft.
- The chimney draw must be between -.45 and -.30 mbars (-.18 and -.12 inches of water).
- The chimney must follow all state and local codes.
- The chimney should be installed by a qualified professional.
- The chimney must be externally supported.
- The chimney can not service any other appliance.
Wiring
Note: Be sure to follow all local, state and federal guidelines. Wiring installation should be preformed by a
qualified electrician.
Your Mini Boiler needs a 120 V connection with a 15 amp circuit for the basic unit. The unit must be properly
grounded to ensure proper operation. Failure to properly ground the unit will result in a voided warranty.
See the wiring diagram at the end of the manual for more information. Connect the pump to a independent,
grounded power source.
After the installation of the WoodMaster add-on water to air exchanger, the air flow may need to be increased
to fuel boilers, electric boilers, and electric/gas boilers. 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 of larger power may be used.)
Direct Drive System
The motor shall not be changed, however the speed of the motor may be increased.
