Burner Connections

1.Make sure the regulator valve and hose connections are securely fastened to the burner and the tank.

If your unit was assembled for you, visually check the connection between the burner venturi pipe and orifice. Make sure the burner venturi pipe fits over the orifice.

WARNING: Failure to inspect this connection or follow these instructions could cause a fire or an explosion which can cause death, serious bodily injury, or damage to property.

2.Please refer to diagram for proper installation. (Figure 2)

3.If the burner pipe does not rest flush to the orifice, please contact 1.800.762.1142 for assistance.

Tank/Gas Line Connection

1.Make 2-3 oz. of leak solution by mixing one part liquid dishwashing soap with three parts water.

2.Make sure control knobs are (OFF) position. (Figure 3)

3.LP: Turn LP gas tank valve to “OPEN”. NG: Turn “ON” natural gas main valve.

4.Spoon leak check solution at all “X” locations (Figures 2, 4a and 4b)

a.LP: If any bubbles appear turn LP gas tank valve to “CLOSED”, reconnect and re-test.

NG: If any bubbles appear turn natural gas main valve “OFF”, reconnect and re-test.

b.LP: If you continue to see bubbles after several attempts, turn LP gas tank valve to “CLOSED” and disconnect LP gas tank and contact 1.800.762.1142 for assistance.
