About Water Quality
• Review all of the installation information in this manual before starting installation. Consider all
the requirements for venting, piping, condensate removal, and wiring.
• The installation location of the water heater should have a minimum clearance of 8 ft. (2.4 m)
from any high heat sources (producing temperatures greater than 158°F (70°C); some examples
include: boiler ventilation pipe, space heater, etc.), as these will cause deformation of plastic
parts or plastic pipe fittings of the unit. Also abide by any heat source manufacturer instructions,
as well as any local, state, provincial, and national codes, laws, regulations, and ordinances when
installing this unit near any high heat sources. If this guideline is not followed, and damage from
a high heat source occurs to the unit, it WILL NOT be covered by the warranty.
• The unit must be installed in a fire retardant area away from all combustible materials. The
minimum clearances from combustible construction are 6 in (152.4 mm) on the sides, 0 in (0 mm)
from the back, and 12 in (304.8 mm) from the top.
• The location chosen and installation MUST comply with the Uniform Plumbing Code (latest
version). If the installation or location violates this code, the warranty will be voided.

adequate clearance for the water heater, as well as adequate options for venting and
drainage, and sufficient access to gas, water, and electrical supplies. Carefully consider the following factors
when choosing an installation location:
Proper maintenance of the water heater is required when water quality does not meet EPA standards.
Damage caused by poor water quality IS NOT covered under the manufacturer’s warranty. The following table
shows the maximum contaminant levels allowed, based on the EPA National Secondary Drinking Water
Regulations (40 CFR Part 143.3). If you suspect that your water is contaminated in any way, discontinue use of
the water heater and contact an authorized technician or licensed professional to investigate further.
If your local water is hard, please review the following recommended treatment and flushing guidelines.
However, first check your local codes for any restrictions on the use of softeners before choosing and
purchasing a softener.
