As an option two heaters may be vented
through an approved common 4" X 4" X 6"
flue Tee, (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" operating switch.
All vent pipe used with a slip-fit connection
must be mechanically secured. 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
0 F.
The vent system must always be adequately
supported to prevent sagging. (Fig: 4 page 6)
