The 720 Series Dual Valve Gas Controls are designed for a wide variety of
heating applications and can be used to replace most constant pilot valves,
including dual valve (six function) models.
The 720 Series constant pilot gas valve is a six function valve incorporating
a manual valve, safety shutoff magnet, dual automatic valves (hence the
term "dual valves"), main gas regulator, and pilot adjustment. Models are
available with and without a pressure regulator. Uni-Kits® are factory-set at
3.5" W.C. for natural gas, but can be converted to L.P. by installing the regulator
conversion kit included.
The 720 Series feature an integral manual selector used to select from the
4 gas flow positions ? off, on, pilot and "set". The "set" position provides
pilot only gas flow during magnet energizing and lock up. Built-in stops
serve to prevent accidental setting to the off position.
The wiring connections, manual selector and adjustments are easily accessible
on top of the valve. With a 3-9/16" swing radius, the 720 series lends
itself well to replacing many OEM valves. Controls are multiposition and can
be mounted in any position (except upside down).
To prevent unsafe attempts at repair, special screws are used and replacement
parts are NOT available.Features
