Product Overview
The DR-RH is a ceramic rayhead assembly for Re-Verber-Ray high-intensity heaters, supplied with ceramics assembled in the combustion chamber. The rayhead assembly forms the infrared combustion surface at the core of the burner: it houses the ceramic combustion grid and holds the nine rods that complete the burner assembly, converting gas combustion into the radiant heat output of the heater.
It replaces GA10-91 and is used on Re-Verber-Ray DR series high-intensity heaters, 30-160 MBH natural gas and 60-160 MBH propane models; see the Fitment panel for the full list. The DR-RH is not interchangeable with the DR-RHP, which is only for the 30-55 MBH propane models.
The DR-RH ships without rods. Nine rods (DR-LROD and DR-SROD types) are sold separately and transfer from the old rayhead into the new assembly during replacement.
Replacement requires disconnecting supply voltage and letting the heater cool fully. Remove the four reflector bolts and slide the reflector up (controls may need to be removed first), then remove the flash shield and the four rayhead bolts to pull the faulty rayhead. Slide the nine rods up and out of the old assembly and install them into the new DR-RH, then reinstall by reversing those steps, ensuring rayhead tabs sit adjacent to manifold tabs. Shut off gas, disconnect power, and verify all connections before returning the heater to service; this work should be performed by a qualified technician. Refer to the installation sheet: DR Rayhead Replacement LSH015.
