PG. 6
WATER DRAINAGE
The oven must discharge through an
indirect waste pipe by means of an air gap.
The drain thread is 1-1/4-inch (32mm) NPT.
A union is required. Install a 1-1/4-inch
(32mm) diameter drain line. The drain line
must always be a positive gradient away
from the Combitherm oven and not more than
12-inches (305mm) before an air gap.
NOTE: In the U.S.A., this equipment is to be
installed to comply with the Basic
Plumbing Code of the Building
Officials and Code Administrators
International, Inc. [BOCA], and the
Food Service Sanitation Manual of the
Food & Drug Administration [FDA].
If several units are to be connected to one
drain pipe, the dimensions of the pipe must
be sufficient to allow an unobstructed water
drain system.
AVERAGE DRAIN WATER TEMPERATURE
149°F (65°C)
STACKING INSTALLATION
Stacking Combitherm ovens require two (2) water connections, two (2) drain connections, and two (2)
electrical connections.
If local code allows,
the water and drain may be
manifolded as long as the size
of the water inlet is increased
to 1-inch (25,4mm) and the
drains include an external vent.
The drawing illustrates one
suggested method of a
manifold installation.
