If installing straight off the back venting with Valor terminal kit
#551DV only, ignore this step:
1. Fit the Dura-vent adapter #817VAK over the appliance vent collars
pushing on firmly.
Align the adapter so that the seam on horizontal Dura-vent pipes is not
at the bottom – Check by temporarily fitting a Dura-vent pipe.
2. Drill through the adapter outer tube and appliance outer collar for
#6 screws. See figure 46. Make sure that the drill does not penetrate the inner
tubes.
3. Secure the adapter to the outer collar with two #6 thread cutting
screws supplied (Fig. 46).

Co-Linear adapter ( see fig. 48 )
( Note – Instructions may vary as 556CLA may be
installed on Top or Back of Heater.)
1. Remove blank plate and gasket to gain access to
exhaust spigot. Retain plate and gasket for re-use later
2. Remove existing outer intake plate. Retain gasket
only for re-use.
3. Remove existing exhaust spigot – gasket below
should remain on heater.
4. Install new co-linear exhaust spigot re-using
existing screws. Ensure all screws are reinstalled tightly.
5. Install new co-linear outer plate ( note – up/down
front/back orientation on drawing) re-using existing
gasket and screws. Use 6 additional screws supplied to
seal outer plate to gasketed flange of exhaust spigot. Connect 3” dia. flex liners directly to outer plate collars using sheet
metal screws. Note - “exhaust” & “intake” must correspond with roof termination.
