PRESSURE RELIEF VALVE (#3)
• A) Apply pipe sealer and Tefl on tape to threads.
• B) Install in threaded coupling in upper center back of boiler.
• C) Tighten pressure relief valve with proper wrench.
• D) Do not over tighten.
Before fi lling the system, ensure the pressure relief valve is installed. Use only a boiler relief valve
set to limit pressure to 30 psi. Failure to comply with these guidelines could result in failure of
the relief valve to operate, resulting in possibility of severe personal injury, death or substantial
property
damage.
To avoid water damage or scalding due to relief valve operation:
• Discharge line must be connected to relief valve outlet and
run to a safe place of disposal
. Terminate the
discharge line to eliminate possibility of severe burns should the valve discharge.
• Discharge line must be as short as possible and be the
same dimension as the valve discharge connection
throughout its entire length.
• Discharge line must
pitch downward
from the valve and terminate at least 6” above the fl oor drain where any
discharge will be clearly visible.
• The discharge line shall
terminate plain (OPEN), not threaded
, with a material serviceable for temperatures of
200°F or greater (copper, black pipe, galvanized or Pex-Al-Pex).
•
Do not pipe the discharge to any place where freezing could occur.
