U.S.: Consult the current National Fuel Gas Code,
ANSI Z223.1/NFPA 54.
Canada: CSA - B149.1 installation code.
Test for leaks. Use a 50/50 solution of liquid soap and
water to test for leaks at gas ﬁttings and joints. Apply
water/soap solution with brush only - do not over apply.
NEVER test with an open ﬂame.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8" test point up stream of the control.
When using copper or ﬂex connector use only ap-
proved ﬁttings. Always provide a union so that gas
line can be easily disconnected for burner or fan servic-
ing. See gas speciﬁcation for pressure details and
ratings. NOTE: If ﬂex connector is used, it must be kept
inside of the appliance. (Fig. 8)
