4.7.1 Mounting Vent Extensions sloping
upwards
1. Use nominal ¾" copper, brass
or stainless steel to prevent flow
restrictions. Larger inside diameter
(ID) can be used also
2. Pipe should slope upward a 1/4"
per foot from the steamer vent
toward a vent hood to allow water
condensing in it to run back to the
steamer and down the drain line.
Minimum recommended slope is ¼"
per foot of hose length.
3. Use rigid pipe rather than flexible
tubing or hose to prevent dips or
sags in the pipe that may collect
water. A puddle of water in the
piping just ½" deep will cause
the steamer to malfunction.
Recommended pipe materials are
rigid ¾" copper tubing (7/8" OD)
or brass/ 18-8 stainless steel pipe
(3/4 NPT or larger). Pipe hangers or
pipe supports should be used every
six feet to prevent long runs from
sagging.
4. A pipe union should be installed next
to the steamer to permit the vent to
be easily disconnected. This allows
the steamer to be easily moved for
servicing.
5. Total length of extended vent piping
should not exceed 15 feet.
