The gas supply pressures for the internal regulator must be verified with a calibrated manometer
while the appliance is operating in maximum load condition. A 1/8” NPT tap is provided in the
front of the internal regulator to measure the burner supply pressure. See Fig.6 Use a pipe joint
compound or sealant designed for the use with liquefied petroleum gas when replacing the 1/8”
NPT tap.
Do not use an excessive amount of sealant in order to prevent potential obstruction of the
gas control valve.

GAS PRESSURE VERIFICATION
GAS CONNECTION - See Fig 5
The Evolution Gas Steamer is manufactured for the use of gas indicated on the data plate. Contact
AccuTemp Products Technical Service Department if your gas supply does not match the gas
indicated on the steamer data plate.
All gas connectors must be in accordance with the local codes and must comply with the latest edition
of the National Fuel Federal Gas Codes, ANSI Z223.1.
A separate gas shutoff valve (not supplied) should be installed in the gas supply line. Use a 1/2” or
larger diameter gas supply line to connect this steamer to the facility supply manifold to ensure a
sufficient volume of gas. The facility supply regulator and manifold must be sized according to the gas
load of all appliances connected to it. If other gas appliances are connected to the supply manifold,
their gas load must be added to the calculations for properly sizing the supply manifold and regulator.
Note: Flexible residential appliance connection hoses are not suitable for this appliance and will void
any warranty.
If your steamer is location is at an altitude of 2000 feet or higher, the orifice must be changed to allow
appropriate gas supply to the burners. Please contact the AccuTemp Products Technical Services
Department for assistance.
The steamer is supplied with an internal gas regulator that is set for the gas type and pressures on
the steamer data plate. An external regulator is not required unless the gas supply pressure is more
than 0.5psig. If an external regulator is required it must be rated 125% of the steamer BTUh rate at
the pressure higher than the rated regulated pressure.
