Lochinvar ArmorX2 1.5 - Manual (Page 34)

Flue vent system and air piping
1. Visually inspect the entire flue gas venting system and air
piping for blockage, deterioration or leakage. Repair any
joints that show signs of leakage. Verify that air inlet pipe
is connected and properly sealed.
2. Verify that water heater vent discharge and air intake are
clean and free of obstructions.
Failure to inspect for the above conditions
and have them repaired can result in
severe personal injury or death.
Check water system
1. Verify all system components are correctly installed and
operational.
2. Watch the system pressure as the water heater heats up
(during testing) to ensure pressure does not rise too high.
Excessive pressure rise indicates expansion tank sizing or
performance problem.
Check expansion tank
1. Expansion tanks provide space for water to move in and
out as the water expands due to temperature increase or
contracts as the water cools. Tanks may be diaphragm or
bladder type. See Section 6 - System Piping of the Armor
X2 Water Heater Installation and Operation Manual for
suggested best location of expansion tanks.
Check water heater 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 6 - System Piping of the Armor
X2 Installation and Operation Manual 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 water
heater relief valve as directed could result
in unsafe pressure buildup, which can
result in severe personal injury, death, or
substantial property damage.
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 water heater
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.
