Rated at 40,000 BTU\/h maximum output, this burner uses a tiered pan-and-grate design to produce tall, layered flames with a prominent center flame while consuming fewer BTUs than comparable vented burner systems. The burner ships as a complete system including a burner pan with integrated grate, sand, glowing embers, Lava Fyre Coals, lava granules, Bryte Coals, a flex connector kit, and a damper clamp. Log sets are sold separately. Installation and service must be performed by a qualified gas appliance technician.\u003c\/p\u003e\n\u003cp\u003eThis burner is rated for indoor, single-sided, vented fireplaces only. It is approved for mobile home installations. Minimum fireplace opening requirements are 25 inches front width, 20 inches rear width, 15 inches depth measured from inside the lip, and 17 inches height. The G31-18\/20 is compatible exclusively with 18-inch gas log sets from an approved list. It is not compatible with remote controls or wall switches. This burner is not suitable for propane or any dual-fuel application — natural gas supply only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-tiered burner design produces tall, layered flames with a prominent center flame and visible ember bed\u003c\/li\u003e\n  \u003cli\u003e40,000 BTU\/h maximum output with lower fuel consumption compared to other full-flame vented burner systems\u003c\/li\u003e\n  \u003cli\u003eMatch-light ignition — no valve included; operates without remote control or wall switch\u003c\/li\u003e\n  \u003cli\u003eIntegrated grate built into burner pan simplifies log placement and reduces setup time\u003c\/li\u003e\n  \u003cli\u003eShips with full media kit: sand, lava coals, lava granules, glowing embers, Bryte Coals, flex connector, and damper clamp\u003c\/li\u003e\n  \u003cli\u003eMobile Home Approved for qualifying installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe G31-18\/20 is certified for use only with specific 18-inch log sets. Designed log sets include Mountain Crest Oak (MCO18), Mountain Crest Split Oak (MCS18), Charred Angel Oak (CHNA18), and Charred Angel Split Oak (CHNS18). Additional compatible log sets include Charred Oak (CHD18\/20), Charred American Oak (CHAO18\/20), Charred Royal English Oak (CHB18\/20), and Charred Split (CHS18\/20). Use with any non-listed log set creates a risk of fire, carbon monoxide exposure, and property damage. Log sets are not universal — verify compatibility before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed gas technician in accordance with the National Fuel Gas Code (NFPA 54) and all applicable local codes. Before servicing or installing, shut off the gas supply at the main valve and confirm the line is fully depressurized. The gas supply connection is 1\/2 inch; inlet gas pressure must be maintained between 5.0 inches water column minimum and 10.5 inches water column maximum. Because this is a vented appliance, the fireplace damper must remain open during operation — the included damper clamp is required to prevent accidental closure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas (NG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum BTU\/h Output\u003c\/strong\u003e: 40,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition Type\u003c\/strong\u003e: Match Light\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVenting Type\u003c\/strong\u003e: Vented\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAllowable Log Set Sizes\u003c\/strong\u003e: 18 inches \/ 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Connection Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gas Pressure (Min.)\u003c\/strong\u003e: 5.0 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Gas Pressure (Max.)\u003c\/strong\u003e: 10.5 inches w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocation of Use\u003c\/strong\u003e: Indoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFireplace Style\u003c\/strong\u003e: Single Sided\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemote Control\u003c\/strong\u003e: Not Available\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertified Usage\u003c\/strong\u003e: Mobile Home Approved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Fireplace Front Width\u003c\/strong\u003e: 25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Fireplace Rear Width\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Fireplace Depth\u003c\/strong\u003e: 15 inches (measured from inside lip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Fireplace Height\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RH PETERSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G31-18\/20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RH PETERSON","offers":[{"title":"Default Title","offer_id":51284145635634,"sku":"G31-18\/20","price":1650.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279956.jpg?v=1781069720","url":"https:\/\/voomisupply.com\/products\/rh-peterson-g31-18-20-vented-gas-log-burner-40000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
