(A) Overall Length
(C1) Minimum Valve Centers
 
Valve Centers shown here are as close together as practical, using the shortest nipples recommended. Longer centers may be obtained by using longer nipples. See Formula.

B1=Valve Take Out
Model 15A: 1.25"

F1=Valve Offset
Model 15A: .75"

offset permits a cleaning brush to enter INFERNO gage from vent or drain port of Valve with open passage through valve body, "offset" from valve stem. This allows blow-down & clean-out while valve stem is closed.

N1 = N2 = 1.5"

Valve Centers (C)
calculated using 1-1/2" long nipples between INFERNO Gage & Valves at Top & Bottom.

Shorter C-C may be obtained by using "Close Nipples" which are 1-1/8" long for 1/2" Ø pipe and 1-3/8" long for 3/4" Ø pipe, although this practice is not recommended because the Gage will butt to the Valve with no room for further tightening.

Adjustment
Floating tailpiece on Valve allows adjustment of Center-to-Center (C-C) of the complete Valve-Gage-Valve assembly. Inferno 15A Single Union valve set allows 1/4" adjustment in final C-C. Other valves such as 15P and 15J offer approx. 3/16" or less adjustment. Some valves have no means of adjustment.
