TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds
1
⁄2 psig (3.45 kPa), the steamer and its individual shutoff valve must
be disconnected from the gas supply piping system.
When gas supply pressure is
1
⁄2 psig (3.45 kPa) or less, the steamer should be isolated from the gas
supply system by closing its individual manual shutoff valve.
FLUE CONNECTION
DO NOT obstruct the flow of flue gases from the flue located on the rear of the steamer.
It is recommended that the flue gases be ventilated to the outside of the building through a ventilation
system installed by qualified personnel.
A minimum clearance of 18"
(45.7 cm) must be maintained from the termination of the flue to the filters
of the hood venting system.
Information on the construction and installation of ventilating hoods may be obtained from the standard
for
Vapor Removal from Cooking Equipment
, NFPA No. 96 (latest edition), available from National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
