the vent kits the manufacturers instructions must be followed.
I
NSTALLING WATER TRIM
Notes: Jacket must be installed on boiler units prior to installation of trim.
PIPING
IMPORTANT: Boilers are to be used with closed system. Any application
that uses water from system, causes the introduction of a frequent supply of
fresh water into the boiler. This will cause damage to the boiler. Use of heat
exchangers will prevent this damage.
PIPING FOR WATER UNITS
NOTE: On knock down boiler only, jacket may be installed after return piping connection, but must be installed prior to adding trim & supply piping.
I. CIRCULATING SYSTEM
A. FORCED CIRCULATION hot water heating system: Use the top
tapping as supply tapping, and use the rear bottom tappings for
the return.
B. A FLOW CONTROL VALVE will prevent gravity circulation.
II. AIR CONTROL SYSTEMS
A. DIAPHRAGM-TYPE COMPRESSION TANKS are used to control
system pressure in an AIR ELIMINATING SYSTEM: an automatic
air vent is used to REMOVE air from the system water. See figure 3.

If system pressure needs further control, add an additional tank or install a
larger capacity tank. The automatic air vent should be installed in the top of
the boiler, as in figure 3.
B. CONVENTIONAL COMPRESSION TANKS (non-diaphragm type) are
used to control system pressure in an AIR COLLECTING SYSTEM. Within
the system, after initial start-up and venting, air is collected in the tank and
acts in contact with the water to control pressure. Air is not vented from this
system. If system pressure needs further control, add another tank in
parallel with the original tank or install a large capacity tank. Locate the
tank at the inlet end of the pump near the boiler. (See figure 3)
C. HOT WATER RADIATION VENTING - Manual air vents should be installed
at the top of all "drops" (where piping goes downward). Air must be vented
or purged from all zone lines to permit proper system heating.
D. PUMP LOCATION - Locating low-head pump(s) on return to boiler is
acceptable for smaller boiler sizes in residences of one or two stories.
The pump location sho
wn in figure 3 is required in large
, m
y
ulti-stor
building installations, especially when high-head pumps are used.
IMPORTANT: Hot water heating systems containing high water volume, such
ould occur with cast iron r
as w
adiation, require special care with air elimination. The circulator pump should be located on the boiler supply pipe and the
expansion tank and air scoop should be located near the pump suction.

OIL SUPPLY PIPING
Install the oil tank or tanks and piping from tank to burner. Follow local
codes and practices, NFPA No. 31, INSTALLATION OF OIL BURNING
EQUIPMENT and the instruction sheet attached to the oil burner pump. A
one-pipe system should be used for gravity fed fuel systems and for lift systems, where the total lift is less than 8 ft. Where the total lift is greater than 8
ft., a two-pipe system must be used. In some instances, local codes may
require a two-pipe system for below grade fuel oil tanks. Be sure to set-up
the fuel oil pump for the piping system used; follow the instructions attached
to the pump. Be sure to include a good quality, low pressure drop fuel oil filter in the supply line from the tank. This is necessary, especially at low fuel
oil flow rates (small nozzle sizes), to prevent nozzle plugging.
WIRING THE BOILER
• The wiring diagrams for the burner and boiler may be found on pages 6-7.
• 24 volt control wiring should be approved Safety Circuit wire, protected
as needed.
• Power supply wiring to the burner must be 14 gauge or heavier, as
required, and should have a properly fused disconnect switch. 120 volt
wiring to pumps and safety controls must also be 14 gauge or heavier.
ust be enclosed in approved conduit.

II. PROVIDING PROTECTION FOR FREEZING
Anti-freeze is sometimes used in hydronic heating systems to protect against freeze-up in the event of power
failure, or safety control shutdown when the building is
unoccupied. It should be recognized that unless the building is kept above freezing temperature by some means,
the plumbing system is not protected.
PROPYLENE GLYCOL is used in the quick-freeze food
industry; it is practically non-toxic. Its use may be permitted
when indirect water heaters are used. When anti-freeze
must be used, inhibited propylene glycol is recommended.
Useful information on the characteristics, mixing proportions, etc. of glycol in heating systems is given in Technical
Topics No. 2A, available from the Hydronics Division of
GAMA, 35 Russo Place, Berkeley Heights, NJ 07922.
Consult glycol manufacturers for sources of propylene
glycol.
DO NOT USE ETHYLENE GLYCOL BECAUSE IT IS TOXIC.
III. OIL BURNER
