Rh Peterson G45-18/20-AN Triple T Vented Gas Burner 70K Btu

Product Description

The RH PETERSON G45-18/20-AN is a Triple T vented natural gas burner designed for single-sided, indoor gas fireplaces. It features a main burner tube running the length of the unit with a smaller front-flame tube that tees off the main body, creating three additional flame outlets for added depth and a more realistic fire appearance. Rated at 70,000 BTU/h on natural gas, this burner is approved for use in mobile homes and requires a minimum fireplace opening of 30 inches wide, 24 inches deep, and 13 inches tall. Installation requires a licensed gas technician and a compatible vented fireplace. The included SPK-26 assembled safety valve is factory-fitted to the unit.

This burner is intended for single-sided, indoor vented fireplaces burning natural gas. It accommodates 18-inch and 20-inch Real-Fyre gas log sets, which are sold separately. Certified for mobile home installation, it suits residential fireplace applications where a traditional log set appearance with a glowing ember bed is desired. The Triple T burner geometry places flames directly beneath and in front of the logs, accentuating front-flame visibility. The burner requires a minimum inlet gas pressure of 5.0 inches water column and a maximum of 10.5 inches water column at the manifold.

Compatibility

Designed for use with specific Real-Fyre gas log sets in 18-inch and 20-inch sizes only. Burners are certified to work with specific log sets and are not universal — using a non-compatible log set creates risks of fire, carbon monoxide poisoning, and property damage. Log set is sold separately.

Installation Notes

Installation must be performed by a licensed gas technician in accordance with local codes and the applicable fuel-gas code (IFGC or NFPA 54). Shut off the gas supply completely before servicing or connecting any components. Verify fireplace dimensions meet the minimum requirements before installation and confirm inlet gas pressure is within the rated range using a manometer before commissioning. Do not use this burner with log sets or fireplace configurations not explicitly approved for this model.
