Locating The Boiler; The Gas Supply - FULTON VMP40 Installation, Operation And Maintenance Manual

Installation

Locating the Boiler

a. The boiler should be located in dry
surroundings on a level base, making
sure that there is sufficient room around
the boiler to enable the operator and/or
the maintenance engineer to gain
access to all parts of the boiler. Check
location for ease of water supply and
electrical connections.
b. Place the boiler on a non combustible
floor with clearances to unprotected
combustible materials, including plaster
or combustible supports.
c. It is necessary to have the following
vertical clearance from the floor to the
ceiling for removal of the burner for
servicing:

The Gas Supply

a. Gas Piping should be installed in
accordance with National Fuel Gas
Code, ANSI-Z223-1-1984 or latest
addenda and any other local codes
which may apply. In Canada gas
installations must be in accordance with
the current CAN/CGA B149.1 and .2
and/or local codes.
b. Install a dirt trap ahead of all of the gas
valves.
c. The pipe and the fittings used must be
new and free of dirt or other deposits.
d. The piping must be of the proper size to
ensure adequate gas supply to the gas
head assembly. Consult your gas
company for specific recommendations.

e. 7" - 11" wc gas pressure is required
2794
during run for 40-60 HP boilers with
2921
standard burners. 9"-11" wc gas
3175
pressure is required during run for 80
3302 100 HP boilers with standard CSD-1
burners, 11"-13" wc gas pressure is
3302
required for 80-100 HP IRI boilers. 40"
3683
W.C. is required for 130-150 HP
3683
f. For propane or butane gas: see "e"
above. Propane not available for LoNOx
boilers.
g. When making gas piping joints, use a
sealing compound resistant to the action
of liquefied petroleum gases. Do not use
teflon tape on gas line threads.
h. The main and the pilot gas pressure
regulators must be vented to the
atmosphere.
i. After gas piping is completed carefully
check all piping connections, (factory
and field), for gas leaks. Use a soap and
water solution.
CAUTION
Some soaps used for leak testing are
corrosive to certain types of metals.
Rinse all piping thoroughly with clean
water after leak check has been
completed.
j. The boiler must be disconnected at the
boiler shut off valve from the gas supply
piping system during any pressure
testing of the system at pressure in
excess of 1/2 PSIG-14" W.C.
k. The boiler must be isolated from the gas
supply piping system by closing the
shut-off cock during any pressure
testing of the gas supply piping system
at pressures equal to or less than 1/2
PSIG--14" W.C.
