Mounting vent Extensions On Two Steamers on a Double
Stack Stand.
DO NOT connect Drain or Vent lines on multiple
appliances. Each appliance should have its own dedicated
drain and vent.
Each steamer’s vent must be extended individually. Tying mul-
tiple vents together will result in the steamers being unable to
regulate heat.
For the both steamers, follow the instructions as provided above
in
Extension Sloping Upward.
The lower steamer’s vent must exit above the top of the upper
steamer (FIGURE 14).
When designing the extension to slope downwards, whether us-
ing rigid or flexible hosing, pipe hangers or pipe supports should
be used every six feet to prevent long runs from sagging. The
end of the hose/pipe should not be submerged to prevent steam
backups (FIGURE 15).
Extension Sloping Downwards (FIGURE 13)
1. Use nominal ¾” or larger inside diameter (ID) to prevent
flow restrictions.
2. Pipe should slope downwards from the steamer vent
to a floor drain to allow water condensing in it to run
unimpeded into the floor drain.
3. For downward sloping extension to a floor drain ONLY
– ¾ ID or larger reinforced silicone hose (auto radiator
hose) may be used. The hose end must be open and not
submerged. Avoid any low spots that will cause puddles of
water and increase of back pressure.
4. Total length of extended vent piping should not exceed 15
feet.
