ƽ 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.
3. Replace the front access door.
Test low water cutoff (if installed)
1. If the system is equipped with a low water cutoff, test the
low water cutoff periodically during the heating season,
following the low water cutoff manufacturer’s
instructions.
Reset button (low water cutoff)
1. Testing the low water cutoff shuts the unit off. Press the
RESET button on the low water cutoff bracket to turn the
unit back on.
Check appliance piping (gas and water)
1. Remove the appliance front access door 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 appliance following the
procedures on page 8. 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.
ƽ 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 Copper-fin II
Installation and Operation 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, following
the operating instructions on page 8 of this manual. 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 8 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 appliances used for domestic water
heating, they must operate year-round.
