The unit is shipped from the factory without a baffle
installed. On the natural gas units, the baffle should be
sufficient for venting up to 20 feet (6 m) off the top of the
unit. An extra baffle plate is shipped with the unit for instal-
lations of 20 feet and above.
Remove four (4) screws holding baffle plate. Add extra
baffle pate and reinstall screws. Align slots in baffle plates
so the slots are closed. Retighten screws.
NOte: For propane (LP) units the baffle assembly is com-
pletely removed for venting under 20 ft. (6 m). For venting
20 ft. and above, the baffle assembly is to be used with
only one (1) baffle plate installed. Figure 17
