Answer to Question 1

Because this system uses the main burner assembly as the ground terminal of the spark system, it is absolutely necessary that the gas burning unit be thoroughly grounded to the electrical supply ground.

Answer to Question 2

Manual control for ignition and normal operation; Pilot supply, adjustment, and safety shutoff; Pressure regulation of burner gas feed;
On/off electric solenoid valve controlled by the room thermostat.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
