NO more the then the actual pressure / temperature rating as per NBBI /ASME
NONE a boiler is a boiler and a water heater is a water heaterSEE ASME section IV or the NBBI
Nope NFPA 54 / ASME / NBBI / AGA / GAMA and CS are the ones who decide the proper sizes
No, just have a stationary engineer license or a boiler operating license or a back flow certificate or have passed the ASME / NBBI code tests
Steam 15 PSI or domesticwater supply most fittings are rated for 125#=When in doubt check the ASTM/ ASSE/ASME or FS /CS /NBBI=

200 temp on resident water heater 180 is ok BUT in extreme cases over 225 is used and according to the ASME /NBBI 250 DEG @160 PSI is considered a low pressure boiler
By simply following the National Board of boiler Inspectors (NBBI) or the manufacturers instructions about the proper use of the blow down valves that comes with most 20th century heating units over 10 gallons
HECK NO READ the ASME code or the NBBI Also read up on valves and what they are designed to do. A "Globe" valve is used for THROTTLING and severely restricts flow Personally I like using a GATE valve in combination with a ball valve for Blow down applications
I think 'him or me' as you are contracting 'contact him or contact me'. By contrast 'he or I will contact you' because that contracts 'he will or I will contact you'
Force can be both contact or non-contact
