Note: Have the gas supply line installed in accordance with local building codes, if any. If not, follow ANSI 223.1. Installation should be done by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter.)

•Purge should be performed by qualified technician.
•Ensure adequate ventilation.
•Ensure there are no ignition sources such as sparks or open flames.
•Incoming gas line should be piped to the 1/2 in. connection.
•The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa).
•A small amount of air will be in the gas supply lines. When first lighting appliance it will take a short time for air to purge from lines. Subsequent lighting of the log set will not require such purging.

D. High Altitude Installations
OMNI gas appliances are tested and approved without re- quiring changes for elevations from 0 to 2000 ft in the USA and Canada.
When installing this appliance at an elevation above 2000 ft, it may be necessary to decrease the input rating by chang- ing the existing burner orifice to a smaller size. Input rate should be reduced by 4% for each 1000 ft above a 2000 ft elevation in the U.S.A., or 10% for elevations between 2000 and 4500 ft in Canada. If the heating value of the gas has been reduced, these rules do not apply. To identify the prop- er orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4500 ft (in Canada), check with local authorities.
