page 9. Call a qualified service technician.

Have leaks fixed at once by a qualified service technician.
Failure to comply could result in severe personal injury, death
or substantial property damage.
Operate relief valve
Reinstall door securely after inspections.1.
Reinstall the jacket front door after servicing. The boiler front
door must be securely fastened to the boiler to prevent boiler
from drawing air from inside the boiler room. This is par-
ticularly important if the boiler is located in the same room
as other appliances. Failure to keep the door securely fastened
could result in severe personal injury or death. Contact your
installer or technician immediately if the front door does not
correctly in place or if the door gaskets are damaged.
Before proceeding, verify that the relief valve outlet has been piped 2.
to a safe place of discharge, avoiding any possibility of scalding from
hot water.
To avoid water damage or scalding due
to valve operation, a metal discharge
line must be connected to relief valve
outlet and run to a safe place of disposal.
This discharge line must be installed by
a qualified heating installer or service
technician in accordance with the in-
structions in the Ultra Boiler Manual.
The discharge line must be terminated
so as to eliminate possibility of severe
burns or property damage should the
valve discharge.
Read the boiler pressure/temperature gauge to 3.
make sure the system is pressurized. Lift the relief
valve top lever slightly, allowing water to relieve
through the valve and discharge piping.
If water flows freely, release the lever and allow the 4.
valve to seat. Watch the end of the relief valve dis-
charge pipe to ensure that the valve does not weep
after the line has had time to drain. If the valve
weeps, lift the seat again to attempt to clean the
valve seat. If the valve continues to weep afterwards,
contact your qualified service technician to inspect
the valve and system.
If water does not flow from the valve when you 5.
lift the lever completely, the valve or discharge line
may be blocked. Immediately shut down the boiler,
following the operating instructions on page 9. Call
your qualified service technician to inspect the
boiler and system.
