2.4 SITE PREPARATION
Ensure that the site selected for installation of the Innovation Water Heater includes:
• Access to AC Input Power at either:
o 110 VAC, Single-Phase, 60 Hz @ 20 Amps
o 220 VAC, Single-Phase, 50/60 Hz @ 20 Amps – International Models only
• Access to a Natural Gas line with a minimum pressure of 4 inches W.C. (1.0 kPa) with
the unit operating at maximum capacity.
2.4.1 Installation Clearances
All Innovation models are packaged in enclosures having identical exterior dimensions. The unit
must be installed with the prescribed clearances for service as shown in Figure 2.4.1-1 (shown
with optional Sequencing Valve). The minimum clearance dimensions, required by AERCO, are
listed below. However, if Local Building Codes require additional clearances, these codes shall
supersede AERCO’s requirements. Minimum acceptable clearances required are as follows:
Sides: 24 inches (0.61 m)
Front: 24 inches (0.61 m)
Rear: 30 inches (0.76 m)
Top: 18 inches (0.46 m)
All gas piping, water piping and electrical conduit or cable must be arranged so that they do not
interfere with the removal of any panels, or inhibit service or maintenance of the unit. Zero side
clearance is also permissible.
