Figure 1 Clearance recommendations

Recommended clearances

Installation location must provide adequate clearances for servicing and proper operation of the water heater. See Figure 1.

•1”clearance is permissible to either side of water heater, but the Instruc- tion label or other labels may be hidden.

•Top (vertical) clearance is 12” minimum.

•Refer to boiler manual for boiler clearances.

Clearance to combustible materials

1.Provide at least ½” clearance between all hot water pipes and combus- tible materials.

Water heater placement

1.Read and comply with “Location,” page 3 of this manual.

2.Select a convenient location for the water heater, based on domestic and boiler piping hook-ups.

3.Keeping the distance between boiler and water heater short will:

•reduce piping heat loss.

•provide minimum friction loss.

Install levelling legs

1.Carefully tip the water heater onto its side.

2.Screw the four levelling legs into the base.

3.Return the water heater to the upright position and set in place.

4.Adjust the legs as necessary to level the water heater.
