instaLLation oF FLue RestRictoR:
Flue Restrictor is necessary to keep the replace running at its intended efciency. They are also required to
counteract the effect that taller vertical vent runs may have on the appliance. The additional venting action that tall
vertical vent systems may have can result in poor pilot and/or burner operations and possibly nuisance shut downs.
Generally, the vent restriction may be less than what is shown in the vent chart, but not greater.

The DV62 has a built in adjustable ue restrictor.
Set the ue restrictor before you install the
rebox liners. The ue restrictor pivots in the
middle and is secured with a T20 screw. Refer
to the Venting Chart (Figure 21) to determine
the correct setting. The vent chart shows the
range of vent setups that you can use when
installing the DV62. The vent chart shows an
appropriate restrictor setting for the vent run
that you are using.
The vent chart is a starting
point for the restrictor
setting. Environment
factors can affect the
restrictor setting such as
altitude, prevailing weather
and wind conditions. Keep
in mind that running a
restrictor setting that is
more restrictive than the
recommended setting
may result in the replace
running at elevated
temperatures which
can result in hazardous
conditions. Do not leave
an installation without
securing the vent restrictor.
