Lighting The Main Burners - Vermont Castings VM400 User Manual

Lighting the Main Burners

1. Always open the Hood completely and always inspect
the Grill and burners to confirm that all components
are properly positioned before lighting the main burners.
WARNING: Never stand with your head directly over the
Grill when preparing to light the main burners, to prevent
possible bodily injury.
2. Always confirm that all of the burner control knobs are
in the OFF position before opening the gas supply.
3. Turn on the propane gas supply valve at the tank (1 to 2
turns) or turn on the main natural gas supply valve (see
Fig. 8).
4. Turn the selected Burner Control Knob to the HIGH
position by pushing down on the knob and turning it
counter-clockwise.
5. Immediately activate the Igniter (see Page 6). The
selected burner should light within five seconds. Light
the burners sequentially from either left to right or right
to left.
WARNING: IF THE SELECTED BURNER DOES NOT LIGHT, immediately turn the burner control knob to the
OFF position, to prevent gas buildup. Wait five (5) minutes for the gas to clear and then repeat the preceding
starting procedure. If the burner will not light when using the Igniter, follow the match lighting instructions
(see Page 8).
6. Confirm that the burner is properly lit and that the flame pattern is as desired, (see Figs. 9a, 9b & 9c, for
the proper flame patterns). If the flame pattern is other than normal, consult the Troubleshooting Guide
on Page 23 for corrective action.
7. Always preheat the grill before starting cooking. Light all burners and adjust them to the HIGH position for
5 to 10 minutes. Before placing any food on the Grill, clean the cooking grids with a brass wire brush.
8. Adjust the Controls to a medium setting for most cooking requirements. A light coating of cooking oil on
the cooking grids, before heating the Grill, will prevent foods from sticking to the Grill.
