Figure 3. Air Eliminating System or Alternating Collecting System. Pipe off to a safe place the relief valve and drain outlet.
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 shown in figure 3 is required in large, multi-story
building installations, especially when high-head pumps are used.
IMPORTANT: Hot water heating systems containing high water volume, such
as would occur with cast iron radiation, require special care with air elimina-
tion. 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.
INSTALLING THE BURNER
See Burner Data, pages 12-13, and Burner Manual supplied with burner. If
burner is not mounted as received, mount to boiler, placing flange over
mounting studs. Use gasket between flange and boiler. Distance between
flange and nose of burner must be as shown in table on page 12 (Burner
Insertion Depth). Check to see that nozzle and settings are as given in burner
data tables, pages 12-13.
