Maintenance Procedures
Check Primary Relief Valve
Inspect the relief valve and lift the lever to
verify flow at least annually or as recom-
mended on the warning tag of the valve.
Before manually operating the pressure
relief valve, ensure the discharge piping is
directed to a suitable place of disposal to
avoid a potential scald hazard. The dis-
charge piping must be full size without
restriction and installed to permit com-
plete drainage of both the valve and line.
If after closing the valve, the valve fails to
seat properly or continually weeps, replace
the relief valve. Ensure the cause of the
relief valve to weep is the valve itself, not
due to system over-pressurization caused
by an expansion tank that is waterlogged or
undersized.
Check Temperature / Pressure Relief Valve
Inspect the T&P relief valve and lift the
lever to verify flow at least annually or as
recommended on the warning tag of the
valve.
Before manually operating the pressure
relief valve ensure the discharge piping is
directed to a suitable place of disposal to
avoid a potential scald hazard. The dis-
charge piping must be full size without
restriction and installed to permit com-
plete drainage of both the valve and line.
If after closing the valve, the valve fails to
seat properly or continually weeps, replace
the relief valve. Ensure the cause of the
weeping is the valve itself and not due to
thermal expansion or a faulty or under-
pressurized thermal expansion tank.
Inspection of Ignition Electrode
Remove the ignition electrode from the
burner mounting plate.
Remove any white oxides accumulated on
the electrode using fine grit sandpaper or
steel wool. If the electrode does not clean to
a satisfactory condition, replace the ignitor.
When replacing the ignition electrode,
ensure the gasket is in good condition and
correctly positioned. Replace gasket if nec-
cessary.
Check All Gaskets
Ensure all gaskets are in good condition,
correctly positioned and sealed. Replace
gasket(s) if necessary, contact Triangle
Tube for replacement part(s).
Check Control Wiring
Inspect all control wiring located behind
the control panel and at the burner. Ensure
wiring is in good condition and properly
connected.
Check Parameter Limit Settings
Check Parameter 1 and 4 for proper settings.
Check Parameter 2 and 3 for a “01” setting.
Perform Start-up and Checkout Procedures
Start the appliance and perform the start-up
procedure as listed in this manual.
Verify the cold water fill pressure is correct
and the operating pressure of the primary
system is within normal operating range.
Complete the checkout procedures as refer
-
enced in this manual.
