Econoburn EBW-100 Installation And Operating Manual - Dition.
BOILERS CONNECTED TO AN EXISTING SYSTEM
i. Shall be installed without interfering with the normal delivery of heated water from the original
boiler.
ii. Shall be installed without affecting the operation of the electrical and mechanical safety
controls of the original boiler.
iii. Shall provide for a changeover from one fuel to the other without requiring manual adjustment
of the controls or components either than the thermostats.
iv. Shall have provisions for preventing, or adequate water capacity within the boiler to prevent
damage from loss of circulation due to electrical power failure.
v. Shall be installed without changing the function of the controls or rewiring the original boiler.
A wiring interconnection is permitted. The electrical system of both boilers shall be powered
from a single branch circuit without exception.
2. A requirement in the recommended piping diagram for the installation of a hot-water circulation
loop that would dissipate at least 10% of the estimated rated heat output of the solid-fuel boiler
when circulation is reduced because of an electrical power failure.
i. The loop can only be made inoperative by a deliberate manual action.
ii. The design parameters for sizing shall be a pipe size > 3/4 inch (18 MM), room temperature of
65°F (18°C), and mean water temperature of 180°F (82°C).
iii. The loop be positioned above the boiler, with features that promote natural thermal circulation
of the water.
3. The recommended piping be such that excessive pressure will not be developed in any portion
of the boiler system.
KEEP THE DOORS CLOSED AND MAINTAIN SEALS IN GOOD CON-
DITION.
CLEANING OF THE HEAT EXCHANGER, FLUE PIPE, CHIMNEY AND
DRAFT INDUCER, IF USED, IS ESPECIALLY IMPORTANT AT THE END OF
THE HEATING SEASON TO MINIMIZE CORROSION DURING THE SUM-
MER MONTHS CAUSED BY ACCUMULATED ASH.
