PLUMBING CONNECTIONS
WATER CONNECTION
Connect the appliance to quality water (refer to
specs below) via a pressure hose with 3/4” (19mm)
couplings. The water pressure needs to be be-
tween 30 psi (min) and 50 psi (max). All ovens are
supplied with a water manifold which allows for
one, cold water only connection to the oven. This
water connector must have a brass water restrictor
attached to it, which is part of the manifold assem-
bly. Should a customer wish to supply treated wa-
ter to the steam generator, a kit can be added to the
oven which supplies a plug for the water manifold
and a separate water flow restrictor.
Water must meet the following minimum require-
ments:
D
Total Dissolved Solids (TDS) content will not
exceed 30 parts per million.
D
Water PH must be 7.0 or higher.
WARNING!!
Operating the appliance without the water
restrictor installed will invalidate the war-
ranty. The use of poor quality water will in-
validate the warranty.

DRAIN CONNECTION
The waste drain assembly must be constructed of
2-inch copper and be atmospherically vented. The
venting must have a riser so the steam vents above
the top of the oven. In a stacked oven configura-
tion, the venting on the bottom oven must vent
above the top oven. It is recommended that sepa-
rate drain lines be run on stacked ovens. Refer to
FIGURE 3 for a recommeded water drain configu-
ration.

STEAM CONNECTION FOR BC14GDS
Steam supply line is 3/4” NPT. Steam must be clean,
dry and potable. A particle screen and bucket trap
may be needed and are recommended. 60 lbs per
hour is the maximum usage per oven. Steam supply
pressure should not exceed 40 to 50 psi. The flow
pressure is 1-1/2 to 3-1/2 psi and is set at the steam
pressure regulator supplied inside the oven.
