quired to convert furnace for use with
propane gas. The efficiency is GAMA
efficiency rating certified. The 58MCB
meets California Air Quality Manage-
ment District emission requirements.
Except for the 140 size unit, all sizes
of the 58MCB can be installed in a
manufactured (mobile) home when the
optional kit is used. Refer to Vent Table
