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 user.
WARNING!!!
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.
14.1.12 - Check boiler area
WARNING!!!
To prevent
potential of severe personal
injury, death, or substantial
property damage, eliminate
all materials discussed below
from the boiler vicinity and the
vicinity of the boiler combustion
air inlet.
If contaminants are found:
Remove products immediately
from the area. If they have
been there for an extended
period, call a qualifi ed service
technician to inspect the boiler
for possible damage from acid
corrosion.
If products cannot be removed,
immediately call a qualifi ed
service technician to re-pipe
vent and air piping and locate
vent termination/air intake away
from contaminated areas.
1. Combustible/fl ammable materials --
Do not store combustible materials,
gasoline or any other fl ammable
vapors or liquids near the boiler.
Remove immediately if found.
2. Air contaminants -- Products
containing chlorine or fl uorine,
if allowed to contaminate the
boiler intake air, will cause acidic
condensate in the boiler. This will
cause signifi cant damage to the
boiler if allowed to continue. Read
the list of potential materials listed in
Section 10.2. If any of these products
are in the room from which the boiler
takes its combustion air, they must
be removed immediately or the boiler
combustion air (and vent termination)
must be relocated to another area.
14.1.13 - Check pressure
gauge
1. Make sure the pressure reading
on the boiler pressure gauge does
not exceed 25 psi. Higher pressure
may indicate a problem with the
expansion tank.
2. Contact a qualifi ed service technician
if problem persists.
14.1.14 - Check vent
piping
1. Visually inspect the fl ue gas vent
piping for any signs of blockage,
leakage, or deterioration of the
piping. Notify your qualifi ed service
technician at once if you fi nd any
problems.
WARNING!!!
Failure
to inspect the vent system
as noted above and have it
repaired by a qualifi ed service
technician can result in vent
system failure, causing severe
personal injury or death.
14.1.15 - Check air piping
1. Visually inspect the air inlet
termination to be sure it is
unobstructed. Inspect the entire
length of air piping to ensure piping
is intact and all joints are properly
sealed.
2. Call your qualifi ed service technician
if you notice any problems.
14.1.16 - Check
condensate drain system
1. Inspect the condensate drain line,
condensate fi ttings and condensate
trap for signs of weeping or leakage.
2. If you detect signs of leakage,
immediately contact your qualifi ed
service technician to inspect the
boiler and system.
14.1.17 - Check boiler
piping (gas and water)
1. If gas odor or leak is detected,
immediately shut down the boiler
following the procedures on page 3.
Call a qualifi ed service technician.
2. Visually inspect for leaks around
water piping. Also inspect the
circulators, relief valve, and fi ttings.
Immediately call a qualifi ed service
technician to repair any leaks.
WARNING!!!
Have leaks
fi xed at once by a qualifi ed
service technician. Failure to
comply could result in severe
personal injury, death, or
substantial property damage.
14.1.18 - Shut boiler down
(unless boiler is used for
Domestic Water)
1. Follow “To Turn Off Gas to Appliance”
on page 3 of this manual.
2. Do not drain the system unless
exposure to freezing temperatures
will occur.
3. Do not drain the system if it is fi lled
with an antifreeze solution.
4. DO NOT shut down boilers used for
domestic water heating, they must
operate year-round.
