lator, which conforms to the National Fuel Gas code, ANSI
Z223.1 (U.S.) or CAN-B149.1 or.2 (Canada) and acts to limit
the downstream pressure to value that does not exceed 0.5
PSI (14" w.c.), must be installed in the gas piping system
upstream of the furnace. Failure to do so may result in a fire
or explosion or cause damage to the furnace or some of its
