Piping should be pressure and leak tested in accordance with
NFGC, local, and national plumbing and gas codes before the
furnace has been connected. After all connections have been
made, purge lines and check for leakage at furnace prior to
operating furnace.
If pressure exceeds 0.5 psig (14-In. W.C.), gas supply pipe nmst
be disconnected from furnace and capped before and during
supply pipe pressure test. If test pressure is equal to or less than
0.5 psig (14-In. W.C.), turn off electric shutoff switch located on
furnace gas control valve and accessible manual equipment
shutoff valve before and during supply pipe pressure test. After
all connections have been made, purge lines and check for
leakage at furnace prior to operating furnace.
The gas supply pressure shall be within the maximum and
minimum inlet supply pressures marked on the rating plate with
the furnace burners ON and OFF.
