TESTING THE GAS SUPPLY SYSTEM
When the 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 the 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 GAS EXHAUST
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 vented to the outside of the building through a ventilation
system installed by qualified personnel.
