Weil-McLain Ultra Oil NX Burner Manual
Any accumulation of soot or debris in chimney
offsets should be removed
Any obstructions such as a protruding joint or a
piece of broken tile wedged in the chimney should
be removed.
No other appliance connection should be made to
the same
fl ue pipe.
The fl ue pipe should have an upward pitch toward
the chimney of at least 1/4” per foot of length. It
should
fi t tightly and should not project into the
chimney.
Any leakage between tiles, around clean-out doors,
or around the vent pipe should be sealed.
Insulated Stainless Steel Chimney Liners
The new designs of high ef fi ciency oil furnaces and
boilers in conjunction with fl ame retention oil burners
are more ef fi cient. One result of increased ef fi ciency is
lower fl ue gas temperatures. As fl ue gases rise in the
chimney, they will cool and condense when they reach
the dew point. The condensation will mix with the sulphur
in the
fl ue gases creating sulphuric acid. The acid will
attack the chimney mortar, brick and clay liners causing
corrosion, deterioration and blockage of the chimney.
Eventually the blockage could prevent exhausting the
fl ue gases. Instead, the fl ue gases could vent out the
barometric damper into the living space.
Therefore, it is strongly recommended that an approved
insulated stainless steel liner be installed.

For those installations not requiring a chimney, such
as through-the-wall vented appliances, follow the
instructions given by the appliance and power venter (if
used) manufacturers.

See NFPA Standard 31 for complete details.
Appliances
located in confi ned spaces:
All con fi ned spaces should
have two (2) permanent openings; one near the top of
the enclosure and one near the bottom of the enclosure.
Each opening must have a free area of not less than
one (1) square inch per 1,000 BTU’s per hour of the total
input rating of all appliances within the enclosure. The
openings should have free access to the building interior,
which should have adequate in
fi ltration from the outside.
The burner cannot properly burn the fuel if it is not
supplied with a reliable combustion air source.
Follow the guidelines in the latest editions of the
NFPA 31 and CSA-B139 regarding providing
adequate air for combustion and ventilation. y

Failure to provide adequate air supply could
seriously affect the burner performance and result in
damage to the equipment, asphyxiation, explosion or
fi re hazards.

NOTE:
Correct chimney design is shown by dotted lines. Incorrect chimney design, as shown by
the solid lines, may result in down-drafts.
