Check boiler piping
1. Check all gas lines and smell for gas odors.
Perform gas leak inspection per steps 1
through 7, Operating Instructions, page 9.
If gas odor or leak is detected, immediately
shut down boiler following procedures on
page 9. Call a qualified service technician.
2. Visually inspect for water leaks around all
piping, circulators, relief valves and other
fittings.
3. Immediately call a qualified service techni-
cian to repair any leaks.
Have leaks fixed at once by a quali-
fied service technician. Continual
fresh makeup water will reduce
boiler life. Minerals can build up
in the heat exchanger, reducing
heat transfer and causing over-
heating. Heat exchanger failure
can occur.
petroleum-based
Do not use
cleaning or sealing com-
pounds
in boiler system. Severe
damage to boiler and system
components can occur, resulting
in possible severe personal injury,
death or substantial property
damage.
Operate boiler relief valve
1. Before proceeding, verify that the relief valve
outlet has been piped to a safe place of dis-
charge, avoiding any possibility of scalding
from hot water.
2. Read the boiler pressure/temperature gauge
to make sure the system is pressurized.
Record pressure in system to refer to after
checking relief valve.
3. Lift the relief valve top lever slightly, allow-
ing water to relieve through the valve and
discharge piping.
4. If water flows freely, release the lever and
allow the valve to seat. Watch the end of the
relief valve discharge 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.
5. If water does not flow from the valve when
you lift the lever completely, the valve or
discharge line may be blocked. Immediately
shutdown the boiler, following the lighting
instructions on the inside jacket top. Call
your qualified service technician to inspect
the boiler and system.

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 accor-
dance with the instructions in the
ECO Tec Boiler Manual
discharge line must be terminated
so as to eliminate possibility of
severe burns should the valve
discharge.
6. Verify and compare boiler pressure returns
to recorded valve pressure before relief valve
was checked. If pressure does not return to
proper valve pressure, call a qualified service
technician.
Operate Domestic Hot Relief
Valve
1. Before proceeding, verify that the relief valve
outlet has been piped to a safe place of dis-
charge, avoiding any possibility of scalding
from hot water.
2. Lift the relief valve top lever slightly, allow-
ing water to relieve through the valve and
discharge piping.
3. If water flows freely, release the lever and
allow the valve to seat. Watch the end of the
relief valve discharge 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.
4. If water does not flow from the valve when
you lift the lever completely, the valve or
discharge line may be blocked. Immediately
shutdown the boiler, following the lighting
instructions on the inside jacket top. Call
your qualified service technician to inspect
the boiler and system.
