Check boiler relief valve
1. Inspect the relief valve and lift the lever to verify
flow as in the following warnings, excerpted from
a relief valve manufacturer’s warning label. Before
operating any relief valve, ensure that it is piped
with its discharge in a safe area to avoid severe
scald potential.
2. Read page 41 before proceeding further.
3. Follow instructions below or perform procedures
per relief valve manufacturer’s printed instruc-
tions.
Safety relief valves should be rein-
spected 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 inopera-
tive. 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 reinspect the boiler relief
valve as directed could result in unsafe
pressure buildup, which can result in
severe personal injury, death or sub-
stantial property damage.
Following installation, the valve lever
must be operated AT LEAST ONCE
A YEAR to ensure that waterways are
clear. Certain naturally occurring min-
eral deposits may adhere to the valve,
rendering it inoperative. When manu-
ally operating the lever, water will dis-
charge 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 or property dam-
age may result. If no water flows, valve
is inoperative. Shut down boiler until a
new relief valve has been installed.
4. 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 under-sizing.
Review with owner
1. Review the User’s Information Manual with the owner.
2. Emphasize the need to perform the maintenance schedule
specified in the User’s Information Manual (and in this manual
as well).
3. Remind the owner of the need to call a licensed contractor
should the boiler or system exhibit any unusual behavior.
4. Remind the owner to follow the proper shut down procedure
and to schedule an annual startup at the beginning of the next
heating season.
Reinstall jacket door after servicing
Reinstall boiler jacket front door after start-up or servicing. The
boiler front door must be securely fastened to the boiler to pre-
vent boiler from drawing air from inside the boiler room. This is
particularly important if the boiler is located in the same room as
other appliances.
Failure to keep the door securely sealed and fastened could result
in severe personal injury or death.
Manual Test Mode for Single and
Multiple Boilers
Single Boiler
1. Navigate to Manual Test Mode screen under DIAGNOSTICS menu.
2. Generate a call for heat and wait until the burner is lit, if not yet in
operation.
3. Press ENTER and select the desired FORCE RATE. Rate will be
forced to setting for 10 minutes.
Multiple Boiler Running
1. Generate a call for heat on a Network Priority or a Local Priority
a. Local Priority—allows Force Rate only on the boiler with the
call for heat. Follow Single Boiler procedure, above.
b. Network Priority—allows Force Rate on any boiler in the net-
work. Follow procedure outline below in steps 2-5.
2. On the Master boiler, navigate to Manual Test Mode screen under
DIAGNOSTICS menu. Select desired boiler to be tested.
3. The Manual Test Mode screen will automatically appear on the boiler
you selected. On the selected boiler’s control, press ENTER and select
the desired FORCE RATE (HIGH, MED, OR LOW).
When forcing a rate on a Network Priority call, only
boilers running Local Priority calls will remain on.
All other boilers on the network will not fire until the
Manual Test has ended. Ensure critical applications
remain heated. Long periods of low heating can cause
property damage.
4. The selected boiler will run at the forced rate until it is either re-
turned to AUTO, the user selects “End Manual Test” on the Master’s
Manual Test Mode screen, or after 30 minutes of inactivity on the
Master control.
5. To test the next boiler, return to the master and select the next de-
sired boiler to test.
