NOTES
:
1. For actual sizes and locations of piping and other connections to the heating boiler, see dimensional
drawing.
2. Shell drain valve and condensate hose should be arranged to permit the fluids to drain freely, by gravity, to a
floor drain. Relief valve discharge should be piped to the nearest floor drain. When no floor drain is
available, the relief valve discharge should be piped vertically to a height 0.5 m above the floor.
3. All (*) items are included separately in shipment.
4. This is a typical installation drawing. Local codes and authorities should be consulted.
5. Locate water inlet and outlet fittings (i.e. .unions, elbows, etc.) a minimum of 0.2 m from heating boiler
fittings, to prevent interference with removal of heater panels.
6. When available gas pressure is greater than 3.49 kPa, a lock-up style regulator must be installed
downstream of the manual shutoff valve to bring the gas pressure down to 3.49 kPa or less.
7. When using the AERCO condensate neutralizer tank, for proper condensate drainage, the neutralizer tank
must be installed in a pit or the boiler and the AERCO condensate trap must be elevated higher than 10 cm
above the floor.
8. At 3.49 kPa or below, a gas regulator is optional unless required by local code.
