Check appliance piping (gas and water)
1. Access the appliance and perform a gas
leak inspection per steps 1 through 7 of the Operating
Instructions on page 8. If gas odor or leak is detected,
immediately shut down the boiler and call a qualified
service technician.
2. Visually inspect for leaks around water piping.
Also inspect the circulators, relief valve, and fittings.
Immediately call a qualified service technician to repair
any leaks.

WARNING
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
1. Before proceeding, verify that the relief valve outlet has
been piped to a safe place of discharge, avoiding any
possibility of scalding from hot water.

WARNING
To avoid water damage or scalding due
to valve operation, a metal discharge
line must be connected to the 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
instructions in the Solution Installation
and Service Manual. The discharge line
must be terminated so as to eliminate
possibility of severe burns or property
damage should the valve discharge.
2. Read the boiler pressure/temperature gauge to make
sure the system is pressurized. Lift the relief valve
top lever slightly, allowing 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 shut down the appliance. Call
your qualified service technician to inspect the appliance
and system.
Shut appliance down (unless boiler is
used for Domestic Water)
1. Follow “To Turn Off Gas to Appliance” on page 9 of this
manual.
2. Do not drain the system unless exposure to freezing
temperatures will occur.
3. Do not drain the system if it is filled with an antifreeze
solution.
4. DO NOT shut down boilers used for domestic water
heating, they must operate year-round.
