Amana CVC96 BB Series Installation Instructions Manual page 25

aluminum-alloy tubing and connectors are coated to
protect against external corrosion when in contact
with masonry, plaster, or insulation, or subjected to
repeated wetting by liquids such as water (except rain
water), detergents, or sewage.
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 fittings 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 fittings required will vary by the side
chosen, location of union and cabinet width. The union may
be placed inside or outside of the cabinet.
