Steam Trim - Burnham V11 Series Installation, Operating And Service Instructions

ALSO, REFER TO BURNER INSTALLATION
MANUAL FOR INSTRUCTIONS SPECIFIC TO
EACH BURNER.
1. In most cases the burner adapter plate carton for
the specified burner will be provided by Burnham.
Power Flame V1122 and V1123 burners require
special adapters that will be provided with the
burner.
2. If adapter is provided by Burnham, open carton
and remove contents. Apply four (4) small dabs
of silastic on rear surface of adapter plate to
temporarily hold gasket in place. Hold adapter plate
in position against burner mounting plate, align
holes and secure with four (4) 3/8" lock washers and
3/8" - 16 x 7/8" lg. cap screws.
3. If adapter is furnished with burner, follow
manufacturer's instructions using gasket material
and hardware provided with burner.
a. Power Flame burners for the V1122 and V1123
are furnished with special adapter plates.
b. All other burners connect directly to the adapter
plate supplied by Burnham.
4. USE A HOLE SAW OR KNIFE TO CUT
BURNER MOUNTING PLATE INSULATION
TO MATCH HOLE SIZE ON BURNER
ADAPTER PLATE. After cutting, remove any and
all loose pieces of insulation which may become
lodged or interfere with the head of a burner air tube
after insertion.
5. Confirm that hole in insulation fits snugly around
burner blast tube. If hole is oversized, remove
burner mounting plate (with burner attached) from
boiler. Use additional fiberglass rope gasket
provided with burner to fill in any space between
insulation and blast tube. If additional rope gasket
is not provided with the burner, use 3/8" fiberglass
rope rated for 2300°F (provided by others).
Reinstall burner mounting plate when finished.
CAUTION
Failure to properly fill all gaps between the
insulation and burner blast tube may result in
damage to the burner.
6. For boilers without tankless heaters, proceed to
Paragraph I (Install Steam Trim) or J (Install Water
Trim).
7. For boilers with tankless heaters, install the
tankless heater manifolds according to Figure 28.
IM P O R T A N T
Water heater manifolds must be removable to allow for
heater repair and replacement, also for the removal of
jacket right side panels for boiler repair and inspection.
Therefore, the recommended use and placement of shut
off valves and unions on all manifold assemblies is
crucial to providing easy access for future servicing.
I.
STEAM BOILERS - INSTALL STEAM TRIM
Items for steam trim are located in the steam trim
carton (except for the separately ordered low cutoff and
tankless heater control). Table IV and Figure 29 show
the proper tappings for each item.
1. Install the gauge glass set.
2. Install the low water cutoff. When using two
LWCO's on a V11 steam boiler, a probe type LWCO
cannot be used in conjunction with a float type. See
Figure 39 for illustration of two float LWCO's. Also
follow manufacturers instructions furnished with
control.
3. Install the Pressuretrol to the boiler using the 1/4"
x 90° (1-7/8" x 4") siphon and the 3/4" NPT x 1/4"
FPT hex bushing.
4. The Pressuretrol must be accurately leveled for
proper operation. It is level when the leveling
indicator hangs freely with its pointer directly over
the index mark inside the back of the case. Level
the controller by carefully bending the steam trap
(siphon loop).
5. Install drain valve supplied by others in tapping B
using the appropriate bushing
6. Install the steam gauge using the 1/2" NPT x 1/4"
FPT hex bushing.
7. Install the safety valve to the back section as shown
in Figure 43. The safety valve is installed in the tee
provided for blowoff piping.
The L404 Pressure Limit contains mercury in a
sealed tube. Do not place limit in the trash at the
end of its useful life.
If this limit is replacing a limit that contains
mercury in a sealed tube, do not place your old
limit in the trash.
Contact your local waste management authority
for instructions regarding recycling and the proper
disposal of this limit, or of an old limit containing
mercury in a sealed tube.
If you have questions, call Honeywell Inc. at
-800-468-502
Safety valve discharge piping must be piped
to within six (6) inches of floor or to floor drain
to eliminate potential of severe burns. Do not
pipe in any area where freezing could occur. Do
not install any shut-off valves, plugs or caps in
discharge piping.
