Installation Clearances - Watts AERCO CFR 3000 Installation And Start-Up Manual

SECTION 2: INSTALLATION

2.3.1 Installation Clearances

The unit must be installed with the minimum prescribed clearances for service listed below. However, if
Local Building Codes require additional clearances, these codes shall supersede AERCO's requirements.
The minimum acceptable clearances required for the CFR 3000 are as follows:
Front: 24 inches (61 cm)
Rear: 24 inches (61 cm)
All gas piping, water piping and electrical conduit or cable must be arranged so it does not interfere with
the removal of any panels or inhibit service or maintenance of the unit.
In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient space
for piping connections and future service/maintenance requirements must also be taken into
consideration. All piping must include ample provisions for expansion.
NOTE: CFR units can be installed with zero side clearances in pairs only. See Appendix A.
If installing a Combination Plant using an ACS panel, identify the Combination Mode Boilers in advance
and place them in the proper location. For more information refer to Section 6.5 of OMM-0164.
NOTE: Ensure condensate assembly is not located over housekeeping pad, so condensate can drain.
Keep area clear and free from all combustible materials and flammable vapors or liquids at all times. Failure
to abide by this warning may result in death, serious bodily injury, and damage to property or equipment.
For Massachusetts installations, the unit must be installed by a plumber or gas-fitter licensed within the
Commonwealth of Massachusetts. The installation must comply with all requirements specified in Section 1.4.
