Correct Termination Assembly for Gas Line to Dryerbox
The Dryerbox® features a “knock-out” port for a gas line, allowing for a convenient and space saving location of the gas valve and termination fitting.
This gas knock-out is 1 inch in diameter and permits ½” galvanized pipe to penetrate or a CSST Termination Fitting with a Jamb nut to securely affix the termination to the receptacle (recommended).
1/2 Inch Galvanized Gas Pipe
When using ½” galvanized pipe, it is best to wrap the throat of the pipe that will come in contact with the receptacle with black vinyl tape. A "best practices" gas line installation is described in CSST Gas Terimination below.
CSST Gas Termination Fitting - Preferred Method of Installing Gas Line (Shown)
The illustration above shows a gas line installation using a CSST gas terimination fitting and corrugated stainless steel tubing. Secure the CSST Termination Fitting with a Jamb nut to securely affix the termination to the receptacle. The gas port can be enlarged or relocated easily with a step bit. The best location may be in the center on the bottom return.
An approved ball style shut-off valve must be used.
Municipal Requirements for Gas Line Installation
Many local governments require the CSST gas termination described above. The National Fire Protection Association provides strong
additional resources including a complete report on the National Fuel Gas Code. The installation of gas utilization equipment, related accessories, and their ventilation and venting systems should always be performed by qualified personnel.
