WARNING
Do NOT use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
D. Appliance Certification
This appliance is design certified by Omni International un- der the ANSI
Gas and Propane Installation Code.
E. Gas Supply Connection
A 3/8 in. flared fitting has been installed on the gas valve inlet at the factory. Ensure fittings are of the appropriate size and type on the gas line connection. If the tubing has to be cut to length be sure to use the proper cutting and flaring tool. Also, be careful not to crimp the tubing while bending. If the tubing becomes crimped, do not use for installation.
Gas resistant pipe compound must be used on all threaded male connections to ensure a tight seal.
F. Gas Pressure
Proper input pressures are required for optimum appliance performance. Gas line sizing requirements need to be made following NFPA51.
WARNING
Fire Risk
Explosion Risk
High pressure will damage valve.
•Disconnect gas supply piping BEFORE pressure testing gas line at test pressures above 1/2 psig.
•Close the manual shutoff valve BEFORE pressure testing gas line at test pressures equal to or less than 1/2 psig.
WARNING
Fire Risk
Explosion Risk
Verify inlet pressures.
•High pressure may cause overfire condition.
•Low pressure may cause explosion.
Install regulator upstream of valve if line pressure is greater than 1/2 psig.
•Gas Supply Pressure: Minimum inlet gas supply pressure must be 7.0 in. W.C. for natural gas or 11 in. W.C. for LP gas for the purpose of input adjustment. Maximum inlet gas pressure must not exceed 10.5 in. W.C. for natural gas or 13 in. W.C. for LP gas. The gas line supplying the appliance must be sufficient size to furnish the appropriate supply pressure to the appliance while operating in the “High” setting.
•Pressure tap screws must be closed before turning gas on to the appliance.
•Gas Line Pressure Test: Perform pressure test according to state and local code (if pressure exceeds 1/2 in. psi (3.5 kPa)) before appliance is connected. Be sure to release air pressure from the gas line before connection is made to the appliance. Excessive pressure will damage the gas control and may cause a gas leak.
•Gas Leak Test: Make sure the gas connections are tight. Turn on the gas and coat each joint with a
•The appliance must only be installed in a
•The minimum permanent free opening (in square inches) that must be provided by the fireplace chimney or damper to vent the flue gases is provided in Tables 1 and 2. If the free opening is smaller than the specified area, do not use this appliance.
•The damper must be removed or fixed in a manner in which will secure it open. Some jurisdictions require the damper to be removed or permanently welded fully open. Check with state and local codes.
•Be sure that the chimney is completely unobstructed to ensure proper ventilation of flue gases including carbon monoxide (CO). CO (a poisonous gas) is tasteless, odorless, colorless and undetectable without proper equipment.
•Refer to Table 3 to determine minimum fireplace opening requirements before proceeding.
WARNING
Asphyxiation Risk
This appliance produces carbon monoxide (CO).
•The free opening areas (in square inches) of the chimney damper as shown in the following tables must be met.
•User must make sure damper is locked open.
•The installer is responsible to ensure proper ventilation of flue gases before appliance is used.
Fire needs to draft properly for safe operation.
