Gas Supply Conversion and Orifice Replacement Guide PURPOSE: If a barbeque or side burner unit is to be operated with a different gas supply other than the one provided by the factory, a conversion kit is required. This change must be done in order to ensure that: • The unit is safe to operate. • The unit has correct combustion of gas. • The unit outputs the expected heat (BTUH’s). • Your warranty is maintained.
BARBEQUES: A typical barbeque unit will have the following burner components: BURNER QUANTITIES: MODEL: SMOKER "U" BURNER SEAR-ZONE™ ROTISSERIE SIDE BURNER AGBQ-30 1 2 ~ 1 ~ AGBQ-30SZ AGBQ-30IR AGBQ-42 AGBQ-42SZ AGBQ-56 AGBQ-56SZ AGBQ-56BFG AGSB-2 AGSB-SZ 1 1 1 1 1 1 1 ~ ~ 1 ~ 3 2 3 2 3 ~ ~ 1 2 ~ 1 ~ 1 1 ~ 1 1 1 1 1 1 1 1 ~ ~ ~ ~ ~ ~ 2 2 ~ 2 ~ TYPICAL BARBEQUE Figure 1 KNOBS FRONT PANEL SMOKER TRAY DRIP TRAY STEPS: Figure 2 1– Remove the knobs from the valve stems by pulling them stra
Barbeques cont. 5– Remove warming rack, grills, briquette trays and “U” burners from the barbeque unit. (Figure 3) 6– Should your barbeque unit be equipped with a Sear-Zone™ burner, also remove it. (Figure 4) WARMING RACK SEAR-ZONE™ BURNER GRILL BRIQUETTE TRAY “U” BURNER (Figure 3) (Figure 4) “U” Burner orifice Location at end of Brass nipple.
Barbeques cont. 8– If your unit is equipped with a Sear-Zone™ burner, the valve has an orifice mounted externally to the valve body. The orifice is directly attached to the barbeque fire box with a bracket and connected to the valve with a flexible stainless tube. (Figure 7) It is mounted on this bracket along with the Sear-Zone™ igniter electrode. Remove and replace this orifice from the inside of the firebox.
Barbeques cont. 10– To replace the rotisserie orifice, it must be accessed from the back of your barbeque unit. Just like the Sear-Zone™ and the smoker unit, the rotisserie unit has an externally mounted orifice connected to the valve body with a long flexible stainless tube. Remove the rear rotisserie access plate (Figure 10) and locate the orifice on the compression fitting that is mounted on the burner bracket( Figure 11). Replace orifice and re-install the access cover.
AGSB-2 Dual Side Burner STEPS: 1- A dual side burner unit AGSB-2 (Figure 12) has the orifices readily available. Simply remove the top grate, burner external brass caps and inner aluminum caps. (Figure 13) 2– Orifices are accessible directly from the top( Figure 14). Remove and replace each orifice as required and re-assemble the side burners.

It is located externally from the control valve in similar configuration as the barbeque unit. (Refer to page 5 point 8).
PRESSURE REGULATORS: Your barbeque grill as well as side burner unit is equipped with a dual gas supply (NG or LP supply) pressure regulator standard from the factory. It is necessary however, to reverse an internal plunger within the regulator to allow for correct pressure to flow to the gas manifold. Also, when converting from natural gas (NG) to liquid propane (LP) your conversion kit will include a 1/2ӯ MPT to 3/8ӯ Male Compression adapter nipple.
Pressure Regulators cont. 2– To convert to pressure regulator from NG to LP (or vice-versa) , remove the brass cap located on the large round dome of regulator body. The cap has a sealing washer; do not lose or damage this sealling washer as it is required for a gas tight seal. (Figure 23) 3– Located on the cap is also a black plastic plunger. This plunger provides the correct pressure to a spring located inside the body of the regulator.
BURNER ADJUSTMENT: As a final step it is now necessary to adjust some burners for the correct air / gas mixture. All burners operate in the same fashion with the exception of the gas valves. Gas valves for Sear-Zone™ and Rotisserie burners have a direct feeding valves. Gas valves for “U” shaped and Smoker burners have “idling” valves. “Idling” valves permit adjustment for the “LOW” setting in the valve to prevent the flame from going out, so they require adjustment when changing the gas supply type.
