Econoburn EBW-100 Installation And Operating Manual - To The Flue.
FLUE PIPE AND CHIMNEY
The Boiler must be located as close as possible to the chimney. It should be ducted so that there
is a minimum number of elbows used. The flue pipe must be installed with a gradual rise of 1/2” or
more per foot from the Boiler to the flue.
WARNING - NEVER ALLOW THE SMOKE PIPE TO RUN DOWNHILL
TO THE FLUE.
The smoke pipe and chimney must be at least 8 inches in diameter, on the smaller sizes and 12”
on the two larger sizes. The flue pipe or a chimney may be of different cross-sectional area than
that of the appliance smoke pipe, provided that sufficient draft is available at the appliance. The
chimney should be low heat masonry or listed type HT pre-fab.
Space must be provided around the smoke pipe and the back of the Boiler to allow easy access
for the purpose of cleaning. Smoke pipes must not be lighter than 24 gauge black steel. All flue
pipe must be securely fastened with at least 3 sheet metal screws at every joint, and properly sup-
ported.
Always meet or exceed flue pipe clearance specifications -18” clearance from flue pipe to com-
bustibles in all directions.
Connect the boiler only to a chimney suitable for solid fuel appliances and capable of venting the
products of combustion. Do not connect the boiler to a chimney flue serving another appliance.
The chimney must be installed with proper clearances above roof and from adjacent structures
and trees. If a masonry chimney is used it must be in good condition and be equipped with a tile
liner. Flue thimble or flue pipe must not extend into the chimney flue, as it will reduce the draft.
Connect only to a flue or chimney capable of maintaining a negative draft of between .02”w.c. min.
and .05”w.c. max. at all times and conditions. To maintain this draft, one or two draft regulators
may be required. To measure the draft, a gauge is needed to show negative pressure in inches of
water volume. Place a 1/4” hole between the boiler and the draft regulator.
WARNING - IF THIS SETTING IS EXCEEDED IT COULD CAUSE A
SOLID FUEL FIRE TO BURN OUT OF CONTROL.
When installing a wood-burning appliance to an existing chimney carefully inspect entire chimney
for the presence of old inlet holes, which may be improperly covered by metal caps or other unac-
ceptable means. Fill any openings with brick and mortar to ensure no hazardous openings exist.
