VII Operating instructions

Starting

boiler

A.This boiler is equipped with a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. The gas supply to this pilot is controlled by Pilot switch box. This boiler is also equipped with an ignition device which automatically lights a second pilot. The gas supply to this pilot is controlled by the Gas control. Do not try to light this pilot by hand.

B.BEFORE OPERATING THE MANUAL PILOT, smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
