The gas piping may enter the left or right side of the
furnace cabinet. The installer must supply rigid pipe long
enough to reach the outside of the cabinet to seal the grommet
cabinet penetration. A semi-rigid connector to the gas piping
can be used outside the cabinet per local codes. 1/2” NPT
pipe and ttings are required. For models with an “L”
shaped manifold, a 4 1/2” long nipple is required. For
models with a hook shaped manifold, a 2” long nipple is
required.
A semi-rigid connector to the gas piping can be used
outside the cabinet per local codes. From the elbow, the
length of pipe and the ttings required will vary by the side
chosen, location of union and cabinet width. The union
may be placed inside or outside of the cabinet.
