Consult last carrier immediately if damage is found. Table 1 shows furnace transition kit usage. are used when replacing an existing horizontal furnace with a GHR26 horizontal allows installation of the GHR26 furnace modification of the existing supply and plenums. Note -GHR26 units can only be installed These kits GSR14 furnace, tt without return air left side discharge when using these transition kits. Note -Some GSR14 units may have been installed with little or no clearance to the unit's top side. Since the GHR26 unit's vent exits this side, may be encountered, ff it is, field transitions may be required.
