fuel. supply. and. heater.. Locate. sediment.
trap. where. trapped. matter. is. not. likely. to.

freeze. A  sediment  trap  traps  moisture  and 

contaminants.. This. keeps. them. from. going.

into fireplace controls. If sediment trap is not 
installed or is installed wrong, fireplace may 

not.run.properly.
