Pressure Relief Valve:

Royall boilers are designed to ASME (American Society of Mechanical Engineers) standards.  All of Royall boilers come with a 30 psi relief valve. 

 Pressure / Temperature Gauge:

Royall boilers have a pressure / temperature gauge on every wood or coal boiler.  The gauge allows you to observe what the Royall boiler is doing when operating.  The pressure / temperature gauge should maintain a 180 degree and 12 -20 psi level.

Circulation Pump:

A simple 6 gpm circulation pump is needed with each Royall boiler to transfer water to and from the boiler and the home or your Royall Redneck Hot-Tub.  

Kitec Fittings:

Kitec fitting are used on the ends of each return and supply line of Pex - Al - Pex underground tubing.  Royall's fittings are compression fittings for best installation practice.

Pump Flanges:

Pump flanges are recommended by Royall with every pump sold.  If you do not have them, get them.  A perfect example of a pump flange is the dead of winter is on us and a terrible snow storm is happening.  Your circulation pump shorts out and you need a new one.  If you do not have flanges you have to drain the boiler down below the level of the pump to change the pump out.  Pump flanges are a simple fix.  Ball valves are on each flange too shut down water flow.  Royall urges the installation of pump flanges on each and every Royall boiler and Royall Redneck Hot - Tubs. 

Underground Pipe:

Royall strongly recommends Pex - Al - Pex underground pipe with each installation of Royall outdoor boilers.  Pex - Al - Pex has a 1" ID instead of the 1" OD that many people promote.  It is proven that heat transfer allows only 80,000 btu's through a 1" line at any given time.  Why put 1" OD with a .75 ID pipe in the ground?
