Selkirk Direct-Temp Metalbestos Direct Vent
Installation Instructions
1. Determine whether the length of pipe fits the appliance
outlet by attempting to engage the parts. If the parts
engage smoothly, proceed to Step 2. If obstructions,
interference or loose fit is noted, contact the appliance
manufacturer or Selkirk Metalbestos with the dimen-
sions of the appliance outlet.
2. Slide the length of pipe over the appliance outlet a
minimum of 1Z\x" and screw to the appliance outlet col-
lar using a minimum of two (2) #8 x 1/4" sheet metal
screws.
Appliance Adapter (AAV)
The appliance adapter (AAV) adapts DIRECT-TEMP to
most direct vent appliances incorporating outlet collars
configured to receive most common 4" (ID) 6⁵\₈" (OD) or 5"
(ID) by 8" (OD) "Twist Lock" Style, direct vent systems.
The adapter incorporates two (2) indentations on the out-
er wall of the inlet end, which are designed to "Twist Lock"
into place upon attachment to the appliance outlet. Align
the adapter indentations with the entry slots of the appli-
ance outlet and slide together. Turn the adapter clockwise
approximately one-quarter turn to lock in place. The outlet
end of the adapter is standard DIRECT-TEMP construc-
tion.

It is not required to apply or use sealant on the inner liner
of DIRECT-TEMP. For outer wall joint sealing consider-
ations, follow appliance manufacturer recommendations.
Joint Connection:
ST221
The pipe and elbows are assembled by inserting the out-
let (male) end of a length of pipe or elbow into the inlet
(female) end of an adjacent length of pipe or elbow. Make
sure the outlet end is fully seated within the inlet end of
the adjoining section and the gasket, located on the inner
liner of the inlet section is fully enclosed by the inner liner
of the outlet of the adjoining section. Push in the Lock Tab
such that it becomes seated within the inward groove of
the adjoining section. This locks the joint in place. (Fig.
33)
