Amana VR8205 Gas Inlet Through Right Side Counterflow, Counterflow Installations

Page 14

When the gas piping enters through the left side of the furnace, the installer must supply the following fittings (starting from the gas valve):

•Straight pipe to reach the exterior of the furnace (Fig- ures 14 & 15).

•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 inch to another pipe size.
