GAS-FIRED WATER BOILER – 80/110/150/199 BOILER MANUAL
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 48 or 51 before proceeding further.
3. Follow instructions below or perform procedures per relief
valve manufacturer’s printed instructions.
Safety relief valves should be reinspected 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
reinspect the boiler 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
or property damage 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 shutdown procedure
and to schedule an annual startup at the beginning of the
next heating season.
Reinstall jacket door after
servicing
Reinstall boiler jacket door after start-up or servicing.
The boiler jacket door must be securely fastened to the
boiler to prevent 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.
Inspect boiler jacket door gaskets on front of cabinet.
Gaskets must be in good condition, with no tears or gaps.
Replace if necessary.
Failure to keep the jacket door securely sealed and
fastened could result in severe personal injury or death.
Combi Models Only:
Check Combi 3-way valve, DHW
function and brazed plate
1. Cycle the 3-way valve by giving a boiler a call for heat
and then turning on a DHW call by operating a faucet.
Ensure that the valve and boiler operation changes from a
space heating call to a domestic call and hot water is being
delivered accordingly. It may be necessary to run “3 way
valve test” listed on page 112.
2. Check for water leaks around 3-way valve, brazed plate,
and brazed plate manifold fittings.
Clean DHW brazed plate
DHW/Combi brazed plate should be cleaned annually
according to the instructions starting on page 131. Cleaning
maybe required more frequently depending on water quality.
Clean DHW external filter and
internal Combi manifold filters
1. Clean the filter on the domestic inlet water external to
the boiler, installed in the near boiler piping. Follow the
manufacturer's recommended cleaning procedure.
2. Clean the Combi Manifold DHW flow switch filter and
the bypass filter according to the instructions on page 135.
Check DHW temperatures
Follow the procedure on page 104 under “Check Thermostatic
Mixing Valve Operation” to ensure proper temperatures at
all domestic hot fixtures. If a recirculation loop is installed,
check to ensure recirculation pump is working properly. Also
check aquastat, timer, and/or occupancy sensor for proper
operation, if used.
Annual startup (continued)
