3. Baffles – The efficiency of the boiler is based on the
insertion of flue baffles supplied with your product.
Under no circumstances are other baffles to be
used on this product. Refer to Section II, Item
F, Paragraph 3 for baffle installation. If there is
any doubt on the application of this boiler on the
intended chimney, consult with your local code
officials. At a minimum, remove the baffles to
increase the stack temperature. See Tables 9A
and 9B for temperature differential (
T) with
baffles IN and OUT. In addition, the lower the
CO
2
level the higher the stack temperature.
WARNING
Remove the baffles if there are any signs of
condensation in the chimney or chimney
connector. Consult with your local chimney
professional for recommendations.
E . MINIMUM CLEARANCES
See Figure 2A for details regarding clearances to
combustibles for the boiler.
F . OPTIONAL AIR INTAKE PIPING INSTALLATION
-
All air for combustion can be supplied directly
to the burner from outdoors providing that the
criteria for chimney, vent connector and minimum
stack temperature outlined in this section can be
maintained.
(ONLY AVAILABLE WITH BECKETT
BURNER) .
Refer to Section I, Paragraph C, Steps
5 and 6 for optional air intake piping installation
information.
2. NFPA 31 and CSA B139 have information to
help the installer make an appropriate choice
of venting materials. In some cases a chimney
may have to be lined to create sufficient draft. In
other cases, the chimney may have to be lined
to prevent the corrosion of a masonry chimney.
Consult with a chimney specialist knowledgeable
on the requirements for chimney requirements in
your area.

Natural Draft Venting
(continued)
CAUTION
Any doubt on the condition of a chimney
or it’s ability to prevent the generation and
accumulation of flue gas condensate, must be
relined according to NFPA 31 (United States) or
CSA B139 (Canada).
!
CAUTION
Use the chimney venting tables as a guide. It
is highly recommended that any borderline
application should result in the relining of
the chimney with a suitable liner that creates
sufficient draft and to protect against corrosion
caused by flue gas condensate.
