1. Read all instructions and warnings before lighting.
2. Check gas control valve and gas cylinder valve to be certain it is in OFF position before connecting
to gas cylinder.
3. Perform soapy water test before each use.
4. Open door(s) during lighting and/or remove all accessories and cooking vessels from in/or on unit.
5. Turn gas cylinder valve on, then turn gas control valve on.
6. Place a long, lit fireplace match stick close enough to burner to ignite.
7. If ignition does not take place within five seconds, turn gas control valve to OFF position and wait
five minutes and repeat match light instructions.
8. After each use, first turn gas control valve off, then gas cylinder valve off. Always allow unit to cool
completely before touching, moving or storing.
IGNITION INSTRUCTIONS
• Inspect hose before each use. If there are signs of abrasion, wear, cuts, or leaks, the hose must
be replaced. DO NOT USE.
• Inspect burner before each use. Check burner and burner venturi tube for insects and insect
nests. A clogged tube can lead to a fire beneath unit.
• Check to ensure the orifice is centered inside the venturi tube. Failure to properly assemble
the valve orifice to the venture tube can result in gas leak or potential fire at connection. See
assembly steps for proper assembly method.
• Check to ensure the igniter pin is properly spaced and aligned to the burner. Igniter pin should
be approximately 1/4" from the burner and aligned to the top of a burner port (Fig. 2). Confirm
spacing is correct by pressing the igniter button and ensuring spark occurs between igniter pin
and burner.
• Connect hose regulator to LP Gas Cylinder (Fig. 1)
1. Make sure gas cylinder valve is closed. Turn valve clockwise until it stops.
2. Make sure burner control valve on smoker is in the OFF position.
3. Remove protective cap from gas cylinder and coupling nut if applicable.
4. Center and insert regulator nipple into valve outlet on gas cylinder as shown in figure on
the left. Turn regulator coupling nut clockwise until it stops. DO NOT OVER TIGHTEN.
• Perform soapy water test.
• Before starting lighting procedure make sure the smoker door(s) are open.
• When lighting burner remove all parts inside or on unit to prevent explosion from gas build up.
• To use, turn gas cylinder valve ON, push burner control valve in and turn counter-clockwise 1/4
turn to HIGH setting. Push ignitor button to light.
• If ignition does not take place within five seconds, turn burner control valve to OFF position and
wait five minutes and repeat lighting procedures. If ignition still does not occur, see match light
instructions.
• Always ensure that smoker door(s) are open before igniting. Gas can accumulate in smoker.
• If flame goes out during cooking, turn burner control valve OFF, turn gas cylinder valve OFF, wait
5 minutes, then open door(s) and wait 5 additional minutes before repeating ignition instructions
above.
• Burner control valve adjusts burner flame. Turn valve counterclockwise to decrease flame. Turn
valve clockwise SLOWLY to increase flame. Push burner control valve in and turn clockwise to
shut flame off.
• Visually check burner flame (Fig. 3). A CORRECT FLAME should be blue with a small amount
of yellow at the tip. An INCORRECT FLAME is excessively yellow and irregular. If an incorrect
flame occurs, turn burner control valve to OFF position, turn OFF gas cylinder valve. Allow unit
to cool then loosen shutter screw and adjust air shutter (Fig. 4). If an incorrect flame still occurs
allow unit to cool and then clean burner. Let burner completely dry before re-lighting.
• After use turn burner control valve OFF, then turn gas cylinder valve OFF and disconnect tank.
• Type 1 Regulators will have a hook (Fig. 5). The Regulator Hook is used to keep the regulator off
the ground when removed from the LP cylinder. Attach to unit as shown in image.
