HOOK-UP OF AIR AND WATER OPERATED CONTROLS 
1.  Most air or water operated valves on Hubbell water heaters are controlled by Powers 
Accritem. Occasionally, a Robertshaw Fultrol is furnished which operates identically to the 
Powers control except supply and output connections are reversed in location. Controls are 
normally mounted on the back side of the tank shell.
