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 provide 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
servicing. See gas specification for pressure details
and ratings. NOTE: If flex connector is used, it must be
kept inside of the appliance. (Fig. 8)
