Features
- Two burners, two knobs: each burner is controlled on its own, like a cooktop.
- Up to 24,000 BTU combined: enough output for pots and pans next to the grill.
- Slide-in with front controls: the burner rests on the sleeve lip with no fasteners, so it lifts out for service.
- Natural gas or propane: ships for natural gas with the propane conversion orifices included.
- Matching insulated sleeve: the BSASL12 sleeve lets the burner go into an island built of combustible material.
- Lifetime rust-through coverage: side burners and their housings are on Broilmaster's limited lifetime list.

Installation planning
- Enclosure: surround the burner with non-combustible material, and in combustible construction install the insulated sleeve (BSASL12) first. Installing into a combustible enclosure without the insulated jacket can cause a fire.
- Clearances printed in the manual: 36" from the sides and 36" from the back to adjacent combustible construction below the top of the unit; at least 16" from any wall or surface and from combustible objects; at least 6" behind any hood so it can open.
- Framing: build it level front to back and side to side, cut 4" square openings for the gas and electrical connections at the rear or bottom, and let nothing combustible stand above the top surface or in front of the liner face.
- Setting the burner: it rests on the sleeve lip without fasteners. Do not grout the sides or fasten it in, so it can be removed for maintenance; a non-combustible sealant may fill any gap. Never run the gas hose between the burner and the sleeve.
- Gas: install an accessible shut-off valve on the supply. Broilmaster recommends a stainless steel flex line or a 12 ft hose from the burner to a natural gas supply. Size the supply line for every appliance on it: the manual's table for 3/4" pipe allows 360,000 BTU in total at 10 ft, 245,000 at 20 ft and 115,000 at 80 ft.
- Propane: a professional fits the conversion orifices (remove the grate and brass burner covers, unplug the ignition wires, change the orifices in the venturi tubes, then reassemble). With a propane tank in the island, add vent registers of at least 10 sq. in. each, two per side, one high and one low, with the bottom of each vent at least 2-1/4" above the ground. Hand-tighten the tank connection.
- Leak test: mix one part liquid detergent with one part water, turn all knobs off, turn the gas on and brush the solution on every connection; bubbles mean a leak to tighten or repair. Test before first use, at the start of each season and whenever the tank is changed. Never use a flame.
- Outdoor use only: never under overhead combustible construction, never in a garage, porch, shed, breezeway or other enclosed area, and never on a balcony, deck or patio above ground level.
- To light: push the knob in, turn it a quarter turn and hold a few seconds, then turn left; you should hear a click as the burner lights. If it does not light, turn it off, wait 5 minutes and try again, or hold a long-reach lighter over the burner ports. In cold weather, if you hear a whoosh, turn the knob off and relight.
- Low flame: with the burner lit on LOW, pull off the knob, hold the valve shaft with pliers and turn the adjusting screw with a thin flat-blade screwdriver to the smallest stable flame.
Care: Turn the burner off and let it cool before cleaning. Wash the grates with mild soap and warm water before first use and from time to time, and check and clean the grease tray before each use. Inspect and clean the burner venturi tubes at least twice a year and whenever spiders are active or the burner has not been used for a while, with a wire hook, bottle brush or forced air. Wipe the stainless steel with a soapy cloth and rinse, remove food residue promptly, polish with the grain, and avoid abrasives, steel wool and chlorine cleaners.
Warranty
Broilmaster's stainless steel specification sheets list side burners and side burner housings among the components with a limited lifetime warranty against rust-through; valves, knobs, ignitors, labels, hoses, fittings and other parts have a limited 1-year warranty. The warranty printed in the side burner manual covers the original purchaser only, requires installation by a qualified installer and proof of purchase, and excludes damage from misuse, improper installation or storage and lack of maintenance, unauthorized service, removal and reinstallation, and travel, diagnostic, freight, service-call and labor costs; claims go through the installing dealer. That printed warranty names the G-Series grill models, so contact us to confirm the burner's terms before you order.
