Code restrictions

National Standard Plumbing Code

1.Single-wall heat exchanger in water heater complies with National Standard Plumbing Code, provided that:

a.boiler water (including additives) is practically non-toxic, having toxicity rating or class of 1, as listed in Clinical Toxicology of Commercial Products, and

b.boiler water pressure is limited to maximum 30 PSIG by approved relief valve.

Uniform Plumbing Code

1.Single-wall heat exchangers are permitted if they satisfy all of the following requirements —

a.The heat transfer medium is potable water or contains only substances which are recognized as safe by the U. S. Food and Drug Adminis- tration.

b.The pressure of the heat transfer medium is maintained less than the normal minimum op- erating pressure of the potable water system.

c.Exception: Steam complying with #a, above.

d.The equipment is permanently labeled to indicate that only additives recognized as safe by the FDA shall be used in the heat transfer medium.

2.Other heat exchanger designs may be permitted where approved by the Administrative Authority.

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.
