Product Overview
The TP-221 is a Glo-Bar holder gasket manufactured by Re-Verber-Ray (Detroit Radiant Products) for the ignitor mounting assembly on Re-Verber-Ray tube heater burners. Detroit Radiant Products also lists it under the alternate number 24KT70. In the burner assembly, it seals the mounting point where the Glo-Bar or hot surface ignitor passes into the burner housing, preventing air and combustion gas leakage around the ignitor holder. It is a wear item, replaced whenever the ignitor itself is serviced or the gasket shows cracking, hardening, or a poor seal.
The TP-221 fits a broad range of Re-Verber-Ray tube heater series, including the CL3, CX3, DSRF, DSRL, DSRS, DX2, DX3L, HL2, HL3, LD3, LS3, and MP3 lines; Re-Verber-Ray's own listing states it fits all DRP burners except the DES and Euro series. See the Fitment panel below for the full model list. No superseded part number is documented for this listing.
The TP-221 ships as a single gasket, with no ignitor or mounting hardware included.
When replacing the TP-221, shut off the gas supply and disconnect power to the heater before opening the burner housing. Remove the old gasket, clean the mating surface, and seat the new gasket before reinstalling the ignitor holder. Confirm fit against the heater's installation sheet and have a qualified technician verify burner operation before returning the unit to service.
