Installation Instructions - Crown GSX-7HE Installation & Operation Manual

Gas Fired Steamers
Gas Connections
The pipe thread compound used when installing pipes must be a type that is resistant to the action of liquified
petroleum or propane gases.
If this equipment is being installed at over 2,000 feet altitude and was not so specified on order, contact service
department. Failure to install with proper orifice sizing may void the warranty.
1. The Serial and Rating Plate on the unit indicates the type of gas your unit is equipped to burn. DO NOT connect to
any other gas type.
2. A 3/4" NPT line is provided at rear for the connection. Each compartment is equipped with an internal pressure
regulator which is set at 3.5" W.C. manifold pressure for natural gas and 10" W.C. for propane gas. Use 1/8" pipe tap
on the burner manifold for checking pressure.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for
satisfactory performance. A steady supply pressure, between 6" W.C. and 14" W.C. for natural gas and 12" W.C. and
14" W.C. for propane gas is recommended. With all units operating simultaneously, the manifold pressure on all units
should not show any appreciable drop. Fluctuations of more that 25% on natural gas and 10% on propane gas will create
problems, affecting burner operation. Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt or other foreign matter before connecting the line to the unit. Use pipe joint
compound which is suitable for use with Liquid Propane on all threaded connections.
Test pipe connections thoroughly for gas leaks.
Never use an open flame to check for gas leaks. Check all connections for leaks using soapy water before use.
Electrical Connection
120 VAC-60 Hz - Single Phase
Units with this electrical rating are factory supplied with a three-wire cord and three-prong plug which fits any standard
120V, three-prong grounded receptacle. A separate 15 amp supply is needed for each unit.
Plumbing Connections
An open gap floor drain is required. To avoid injury or damage to the steamer, do not make solid connection to
floor drain.
