Schwank STR Series Installation & Owner's Manual page 17

As an option two heaters may be vented
through an approved common 4" X 4" X 6"
flue Tee, (supplied by Schwank Ltd.) with a
maximum of two per heaters per Tee. Both of
the heaters must then be controlled by one
single common thermostat or "ON/OFF" op-
erating switch.
All vent pipe used with a slip-fit connection
must be mechanically secured.
FIGURE 16 FLUE VENT CONNECTION
The end of the Tube is Swaged and will directly accommodate regular "C" Vent and
fittings for venting to outside. The "C" Vent connection to the radiant tube end must
be secured with sheet metal screws.
Where the vent pipe passes through areas
where the ambient temperature is likely to
produce condensation of the flue gases, the
vent pipe shall be insulated with a suitable
material as approved and specified by the
insulation manufacturer. Insulation may be
subject to temperatures over 500
The vent system must always be adequately
supported to prevent sagging. (Fig: 4 page 6)
