Standard working pressure 30 psi water.
All boilers hydrostatically tested — A.S.M.E.
* For forced hot water heating systems where the boiler and all piping are located within
the area to be heated, the boiler may be selected on the basis of gross D.O.E. capacity
output. The net AHRI output ratings shown are based on an allowance for piping and
pickup of 1.15 (water). D.O.E. capacity gross output is divided by the allowance to obtain
net rating. The manufacturer should be consulted before selecting a boiler for unusual
piping and pickup requirements such as intermittent system operation, extensive piping,
etc.
