Tandoor Baffle Plate AS02 — Heat Deflector, Flame Tamer & Heat Diffuser Plate for Gas Tandoor Ovens

The Tandoor Morni AS02 is the most essential tandoor accessory for any gas tandoor oven — a 3/4 inch-thick heavy-gauge mild steel tandoor baffle plate — also widely known as a heat diffuser plate, flame tamer, baffle burner plate, or burner cover — available in three diameters (12 inches, 17 inches, and 20 inches) to fit the full range of Tandoor Morni gas tandoor ovens. It sits directly above the gas burner inside the clay chamber, where it performs eight distinct engineering functions: shielding the clay pot from direct flame impingement, distributing heat evenly across the clay chamber, storing and radiating thermal energy, catching meat drips to generate smoke, protecting the burner from debris, extending clay pot lifespan, preventing carbon build-up, and enabling easy removal for cleaning and health inspections.

At $220 with free shipping, the Tandoor Metal Plate AS02 ships in a black non-stick finish that resists the acidic marinades used in tandoori cooking — yogurt, lemon, spiced oils — which would corrode an untreated mild steel surface at continuous operating temperatures up to 900 Degree F. Tandoor Morni has manufactured gas tandoor accessories in the USA since 1992, supplying restaurant kitchens from New Jersey to California. It is also the most commonly ordered tandoor replacement part for Tandoor Morni gas oven owners whose original plate has degraded after high-volume commercial use.

Core Engineering Function — What the Tandoor Baffle Plate AS02 Actually Does

In a gas tandoor oven, the burner produces a concentrated jet of flame that rises vertically from a single point at the base of the clay chamber. Without a heat diffuser plate or flame tamer in position, this concentrated flame creates uneven heat zones: the area directly above the burner reaches a significantly higher temperature than the sides and upper walls of the clay chamber, producing inconsistent results — meats that scorch at the bottom while the upper portion cooks more slowly, and naan that chars unevenly across its surface.

The Tandoor Metal Plate AS02 addresses this by acting as a thermal diffusion barrier. Positioned above the burner, it intercepts the concentrated vertical flame — functioning exactly as a high-mass grill heat plate or burner cover does in a gas grill — and converts it into radiant heat that spreads laterally across the entire base of the clay chamber. The 3/4 inch steel thickness is key here: thick steel has significant thermal mass, meaning it absorbs a large amount of heat energy and re-radiates it steadily and evenly rather than transmitting a hot spot directly upward. The result is a clay chamber where the temperature is far more uniform from base to wall to upper section.

A Better Flavorizer Bar — How the AS02 Baffle Plate Generates Authentic Tandoor Smoke Flavour

The Tandoor Metal Plate AS02’s second function is one that most buyers don’t anticipate but quickly come to rely on: it acts as a drip shield and smoke generator — the tandoor equivalent of a flavorizer bar or grill drip tray flame guard, but operating at nearly three times the temperature. When skewered meats hang in the clay chamber, fat and spiced marinade drip off the food as it cooks. In a gas tandoor oven without a baffle plate or burner cover, these drips fall directly onto the burner orifices, which can clog the gas jets and extinguish the flame. With the Tandoor Metal Plate AS02 in position, the drips land on the white-hot metal surface instead, where they vaporise instantly on contact. This vaporisation generates the aromatic tandoor smoke flavour that rises back through the clay chamber and permeates the food — delivering a degree of authentic tandoori character that a gas oven without a flame tamer or deflector simply cannot achieve.

Clay Pot Protection, Burner Cover and Replacement Part

The concentrated heat of a gas burner applied directly to the base of a clay pot creates localised thermal shock — rapid, extreme temperature differences across a small surface area. Clay expands and contracts as it heats and cools, and when this happens unevenly across its surface, the internal stress causes premature cracking. The Tandoor Metal Plate AS02 absorbs and distributes this heat before it reaches the clay base, providing essential clay pot protection and significantly extending the service life of the clay interior.

The Tandoor Metal Plate AS02 is also commonly ordered as an oven accessory spare part for existing Tandoor Morni installations. If your original baffle plate has warped, cracked, or corroded, order directly at +1 (727) 251-6924 quoting SKU 22574 and your oven model to receive the correct replacement diameter.

Airflow Design, Carbon Monoxide Prevention and Gas Oven Heat Shield Function

The Tandoor Metal Plate AS02 is not a solid seal — it is engineered with deliberate perimeter gaps and ventilation geometry that allow secondary air to pass around the heat diffuser plate and reach the burner. This secondary air is essential for complete gas combustion: insufficient air supply causes yellow-tipping flames (incomplete combustion), produces carbon deposits on the clay walls, and in a poorly ventilated installation can generate dangerous carbon monoxide. As a gas oven heat shield, the Tandoor Metal Plate AS02’s positioning and geometry are calculated to create the precise internal backpressure needed to spread heat laterally across the chamber floor without ever restricting the air supply to the point where combustion becomes incomplete.

How to Use the AS02 Tandoor Baffle Plate

Place the Tandoor Metal Plate AS02 on the burner assembly inside the tandoor clay pot before lighting. The plate self-centres over the burner geometry — it is shaped to align correctly without adjustment. Light the gas burner, allow the tandoor to preheat to cooking temperature (typically 35–50 minutes), and cook as normal. The Tandoor Metal Plate AS02 does not require any preparation, seasoning, or adjustment for normal operation. To adjust heat zones during cooking, the plate can be partially repositioned using heat-resistant tongs — moving it slightly to one side creates a hotter zone on the exposed side and a cooler zone beneath the plate.

How to Season the AS02 Before First Use

Before cooking with a new Tandoor Metal Plate AS02 for the first time, perform a short initial seasoning heat sequence to burn off any manufacturing residue and set the non-stick coating:

1. Low heat, 10 minutes: Place the Tandoor Metal Plate AS02 in the tandoor and run the burner at its lowest setting for 10 minutes. Light smoke is normal as manufacturing residue burns off.
2. Medium heat, 10 minutes: Increase to medium flame for a further 10 minutes. The plate surface will darken slightly and the non-stick coating will fully set.
3. Full heat, 5 minutes: Bring to full operating temperature (900 Degree F) for 5 minutes. Allow to cool completely before the first cooking session.

This first-use seasoning is a one-time process only. After the initial session, no further seasoning is required — the Tandoor Metal Plate AS02 is ready for continuous commercial service.

Care and Maintenance

Once a month, remove the Tandoor Metal Plate AS02 after the oven has cooled completely and clean it with a non-abrasive cleaner and a soft sponge. Rinse and dry completely before re-inserting — moisture left on the plate surface at high heat can cause steam pitting on the steel surface over time. The non-stick coating resists most marinade residue, but a monthly deep clean prevents build-up that can affect vaporisation efficiency. The Tandoor Metal Plate AS02 is designed to be removable for exactly this purpose — kitchen staff can lift it out for cleaning or burner inspection without any tools.
