Flue System Approvals And Installations
These models have ue starting collars on both the top
and the back of the unit. Depending upon the installation,
decide which ONE set of starting collars will be used to at-
tach the ue system. The starting collar sealing cap must
remain on the starting collar NOT used.
These models use DVP and SLP series direct ue com-
ponents when using the TOP ue collars and DVP-series
direct ue components when using the REAR ue collars.
Approved ue system components are labeled for identi-
cation. NO OTHER FLUEING SYSTEMS OR COMPO-
NENTS MAY BE USED. Detailed installation instructions
are included with each ue termination kit and should be
used in conjunction with this manual. Figure 7.9 shows
ue system components and terminations.
