After the piping and meter have been checked completely, purge the system of air. Do not bleed the air inside the furnace. Be sure to relight all the gas pilots on other appliances.

PURGING

After the piping has been checked, all piping and appliances receiving gas through the meter shall be fully purged. A suggested method for purging th gas line to the burner is to disconnect the pilot line at the outlet o the pilot valve. Under no circumstances shall th line be purged into the combustion chamber.

After th e gad line to the conversion burner has been fully purged and the pilot line reconnected, the gas supply at other pilot burners located on other gas appliances which were extinguished as the result of interrupted service shall be reignited.
