Install a manual shutoff valve between the gas meter • GAS PIPING CONNECTIONS and unit within six feet of the unit. If a union is installed, General the union must be downstream of the manual shutoff valve, between the shutoff valve and the furnace. CAUTION Tighten all joints securely.
A ground joint union, drip leg, and manual shutoff valve must also be supplied by the installer. In some cases, the installer may also need to supply a transition piece from 1/2" to another pipe size.
