b) The air supply inlet and exhaust outlet must be separated from 3ft. minimum to 10ft.
maximum on the same wall. The exhaust outlet must be installed 4ft. minimum above
and downwind from air supply inlet to prevent exhaust recirculation.
c) Under certain wind conditions, some building materials may be affected by flue products
expelled in close proximity to unprotected surfaces. Sealing or shielding of the exposed
surfaces with a corrosion resistant material (such as aluminum sheet) may be required to
prevent staining or deterioration.
d) Do not locate the vent termination too close to shrubbery as flue products may stunt their
growth or kill them.

Warning
Do not attempt to start boiler before filling and purging boiler heating system. A
dry fire will seriously damage the boiler and may result in property damage or
personnel injury and is not covered by warranty.
a) Completely fill and purge the heating system using the following sample procedure.
Note
The following purge procedure is applicable to the piping configuration as shown
in Figure 15.
1. Close combination shutoff/purge valve in supply, all drain cocks, the
shutoff valve for the pressure reducing (fill) valve, and all manual air
vents.
2. Open all other system shutoff valves one of the zone valves, the vent on
the combination shutoff / purge valve, and the shutoff valve to the
pressure reducing (fill) valve.
3. Water will now begin to fill the system. Air will escape through the vent
on the combination shutoff/ purge valve. Continue filling until a constant
stream of water (no bubbling) is discharged from the vent.
4. Close the zone valve on the purged loop, and open the zone valve on
the next loop to be purged. When all air has escaped and only water is
discharged, close the zone valve. When all zones have been purged.
(one at a time), close the vent on the combination shutoff/ purge valve.
5. At this point, the system has been initially filled. However, air pockets
may still remain at high points in the system and in heating loops above
the level of the combination shut/off purge valve. It is quite possible,
