Installation & Service Manual
Check Expansion Tank
1. Expansion tanks provide space for water to move in
and out as the heating system water expands due to
temperature increase or contracts as the water cools.
Tanks may be open, closed, diaphragm or bladder
type. See Section 4 - Hydronic Piping for suggested best
location of expansion tanks and air eliminators.
Check fill water meter
1. Check fill water meter for water usage. If the amount
exceeds 5% of your system volume, you could have a
leak. Have the system checked for leaks and fixed by a
qualified service technician.
Test boiler water
1. Test boiler water. Reference the Copper-Fin Installation
and Operation Manual for guidelines. When test
indicates, clean system water with approved system
restorer following the manufacturer’s information.
Check Relief Valve
1. Inspect the relief valve and lift the lever to verify flow.
Before operating any relief valve, ensure that it is piped
with its discharge in a safe area to avoid severe scald
potential. Read Section 4 - Hydronic Piping before
proceeding further.
Safety relief valves should be re-inspected
AT LEAST ONCE EVERY THREE
YEARS, by a licensed plumbing contractor
or authorized inspection agency, to
ensure that the product has not been
affected by corrosive water conditions
and to ensure that the valve and discharge
line have not been altered or tampered
with illegally. Certain naturally occurring
conditions may corrode the valve or its
components over time, rendering the
valve inoperative. Such conditions are
not detectable unless the valve and its
components are physically removed and
inspected. This inspection must only
be conducted by a plumbing contractor
or authorized inspection agency – not
by the owner. Failure to re-inspect the
boiler relief valve as directed could result
in unsafe pressure buildup, which can
result in severe personal injury, death, or
substantial property damage.
⚠ WARNING
Following installation, the valve lever
must be operated AT LEAST ONCE
A YEAR to ensure that waterways are
clear. Certain naturally occurring
mineral deposits may adhere to the valve,
rendering it inoperative. When manually
operating the lever, water will discharge
and precautions must be taken to avoid
contact with hot water and to avoid water
damage. Before operating lever, check
to see that a discharge line is connected
to this valve directing the flow of hot
water from the valve to a proper place
of disposal. Otherwise severe personal
injury may result. If no water flows, valve
is inoperative. Shut down the appliance
until a new relief valve has been installed.
2. After following the above warning directions, if the relief
valve weeps or will not seat properly, replace the relief
valve. Ensure that the reason for relief valve weeping is
the valve and not over-pressurization of the system due to
expansion tank waterlogging or undersizing.
