TrueFlame Side & Power Burner Size Guide: TFSB2 and TFPB

The TFSB2 and TFPB share a product page on the storefront but use distinct cutouts. Plan the rough opening for each burner separately based on which build you're installing. Three dimensions decide whether the burner head will drop in:

• Width. Side-to-side along the front face of the island. Cutout width: 10¾″ for TFSB2; 14″ for TFPB.
• Depth. Front-to-back from the inside of the front island wall to the inside of the back wall. Cutout depth: 20½″ for TFSB2; 18¾″ for TFPB. The TFSB2 reaches farther back into the island; the TFPB sits slightly forward to accommodate the dual concentric burner head.
• Height (drop). Top-of-counter down to the bottom of the island enclosure. Cutout height is uniform across both builds: 7¾″.

Both burners are designed to drop into the same island as a TrueFlame TF or TFE grill. If you're installing the grill and a burner side by side in the same island, plan the spacing between the two cutouts so that the surrounding non-combustible clearance (2″ minimum on each side) is satisfied on both units — the grill's right-side clearance and the burner's left-side clearance can share the same non-combustible material but the total gap must equal the larger of the two requirements.

Cutout dimensions sourced from the TrueFlame Side & Power Burner owner's manual. All dimensions assume a non-combustible enclosure. Both burners drop into the cutout from above and rest on the surrounding countertop via the integral hanger flange.

Overall head dimensions sit larger than the cutout because the head includes the hanger flange that rests on the counter and the control panel that extends forward of the firebox. Use the cutout dimensions above for framing the rough opening; use the overall dimensions below to verify counter footprint and surrounding clearances:

Per the TrueFlame Side & Power Burner owner's manual, every TFSB2 or TFPB install must maintain the minimum clearances below. The clearance scheme matches the TF grill scheme (2″ non-combustible), but the required exhaust-hood CFM matches the higher TFE / griddle requirement (1,200 CFM).

The 2″ non-combustible clearance applies to the right side, left side, and rear of the burner. Backsplash clearance is also 2″ minimum from the rear of the unit when the backsplash is non-combustible.

If the side or power burner is installed under a covered patio with an exhaust hood, the hood area above the cooking surface must be larger than the cooking area of the burner, and the blower must produce a minimum of 1,200 CFM. Installation in fully enclosed patio areas is not recommended. This 1,200 CFM requirement is higher than the 1,000 CFM specification for the TF grill series — if pairing a TF grill and a power burner on the same hood, size the blower to the higher 1,200 CFM figure.

Using either burner in windy conditions may disrupt the flame. Position the burner so that any prevailing wind hits the rear or side rather than the front control panel. The TFPB Power Burner ships with an integrated wind shield (part of the burner head) that protects the inner ring; the TFSB2 does not include a wind shield. For especially exposed patios, plan a non-combustible side wall on the windward side of the burner cutout.

A pressure regulator must be installed on the gas line; never connect a gas line directly to the burner. Removing or failing to install the pressure regulator can result in fire, serious injury, and voids the Gold Standard Lifetime Warranty. The factory regulator orifice is tuned for the gas type specified on the rating plate; converting to a different fuel requires the included orifice conversion kit.

The TFPB Power Burner delivers more than twice the BTU output of the TFSB2 Double Side Burner — sized for stir-fry, paella, low-country boils, and outdoor stockpot cooking. The two independent control valves on the TFPB allow the inner ring and outer ring to operate separately, giving precision control over how much heat reaches the centre vs the perimeter of the wok or stockpot.

To connect a TrueFlame side or power burner to the same gas supply line as a TF or TFE grill, install a 3/8″ threaded T-adapter fitting on the supply line — one branch routes to the grill, the other to the side or power burner. The TrueFlame owner's manual includes a side-burner connection diagram (Figure 8 in the LP installation section) showing the recommended layout. A licensed gas technician should install all gas lines.

Size the supply line based on the peak demand of the grill plus the burner. Combined BTU demand for common pairings:

• TF40 + TFPB Power Burner: 80,000 BTU (TF40 main + rear) + 60,000 BTU (TFPB) = 140,000 BTU/hr peak.
• TF32 + TFSB2 Side Burner: 66,000 BTU (TF32 main + rear) + 24,000 BTU (TFSB2) = 90,000 BTU/hr peak.
• TFE32 + TFSB2 Side Burner: 56,000 BTU (TFE32 main only) + 24,000 BTU (TFSB2) = 80,000 BTU/hr peak.

• LP models are designed for use with a standard 20 lb. liquid propane cylinder with a Type 1 valve connection. The cylinder is not included.
• The LP cylinder must be stored outdoors in a well-ventilated area, out of reach of children. Never fill the cylinder beyond 80%.
• If installing in an enclosure, ventilation is required on opposite sides to create cross-ventilation — propane is heavier than air and vents should be located near the bottom of the enclosure.
• Check for leaks with soapy water after every cylinder change.

Both the TFSB2 and the TFPB ship with a transformer that powers:

• The full-length exterior LED bar above the knobs (control-panel illumination).
• The individual LED indicators behind each knob.

A standard 120V outlet within reach of the burner enclosure is required. Plug the transformer into the outlet; the supply cord routes from the outlet to the back of the burner firebox.

• Use a properly grounded 120V outlet in accordance with local codes, or in the absence of local codes, with the National Electrical Code (ANSI/NFPA 70) or the Canadian Electrical Code (CSA C22.1), whichever is applicable.
• Keep all electrical supply cords and fuel supply hoses away from any heated surface.
• The Gold Standard Lifetime Warranty covers the transformer, LED bulbs, wire harness, and switches for 3 years (lifetime coverage on the rest of the stainless construction).

If pairing a TFSB2 or TFPB with a TF grill in the same island, the transformer for each unit needs an independent power feed. A single 120V outlet with two receptacles can serve both — verify the outlet is rated for the combined load and is GFCI-protected per local code.

All BBQ islands housing a TrueFlame side or power burner must be manufactured from non-combustible materials. Cement board with steel studs and proper ventilation per local codes is the recommended construction. A minimum 4″ vent size is required — one at the top and one at the bottom — to provide free-flowing air and keep the island cool during operation.

If installing a grill and a burner side by side in the same island, plan the spacing between the two cutouts so that the surrounding non-combustible clearance (2″ minimum on each side for TF; 4″ minimum for TFE) is satisfied for both. The shared wall between the grill cutout and the burner cutout can be a single piece of non-combustible material — but the gap between the two appliances must equal the larger of the two clearance requirements (4″ if one is a TFE).

If the burner is installed in a built-in island and the fuel is propane (TFSB2L, TFPBL), the LP cylinder must be stored outside the cooking enclosure in a well-ventilated area. Never store a spare LP cylinder under or near the appliance. If a TFSB2L or TFPBL is paired with a TF or TFE grill on a freestanding cart, propane storage is built into the cart base with cylinder lock-down hardware — see the TrueFlame Grill and Griddle Carts for the matching cart SKU.

The TrueFlame Gold Standard Lifetime Warranty applies to the original purchaser at the original site of delivery with proof of purchase and photo documentation only.
