Figure 1 - Recommended Service Clearances
Part 3 - Piping
A. Plumbing
The use of heat, such as blow torches, near the tank may cause
distortion to the high density polyethylene wrapper. Such damage
is NOT covered by warranty. Exercise caution whenever using heat
sources near tank.
Total Dissolved Solids (TDS) less than 500 ppm (mg/L)
•
Total dissolved solids are minerals, salts, metals, and charged
particles that are dissolved in water.
•
The greater the amounts of TDS present, the higher the
corrosion potential due to increased conductivity in the
water.
•
If using softened water to fill the appliance, it is still possible
to have high TDS. This water can be corrosive. Consult local
water treatment companies for other treatment solutions to
reduce this affect.
*NOTE:
To promote appliance service life, it is strongly recommended
to follow the maintenance procedures in this manual.
C. Optional Equipment
Below is a list of optional equipment available from HTP:
•
Aquastat Cover with BX and Line Cord (GL-50 Models Only) Part
# GL-KT1
•
Aquastat Cover with BX, Line Cord, and Bronze Pump (GL-50
Models Only) Part # GL-KT2
It is mandatory that all plumbing be done in accordance with federal,
local, and state plumbing codes and practices. Failure to properly
install the storage tank WILL VOID the warranty. It is also necessary
to use both thread tape and pipe dope on all mechanical plumbing
connections.
Dielectric fittings must be used on water connections.
When filling the storage tank, open a hot water tap to release air
in the tank and piping. Failure to do so could lead to improper
operation and damage to components.
Ensure the location can support the entire filled weight of the
storage tank. Failure to properly support the storage tank could
result in property damage, severe personal injury, or death.
This storage tank must not be located near flammable liquids such
as gasoline, butane, liquefied propane, adhesives, solvents, paint
thinners, etc., as the controls of this storage tank could ignite these
vapors and cause an explosion resulting in property damage, severe
personal injury, or death.
B. Water Chemistry Requirements
Chemical imbalance of the water supply may affect efficiency and
cause severe damage to the appliance and associated equipment.
Water quality must be professionally analyzed to determine whether
it is necessary to treat the water. Various solutions are available to
adjust water quality. Adverse water quality will affect the reliability
of the system. In addition, operating temperatures above 135
o
F will
accelerate the build-up of lime scale and possibly shorten appliance
service life. Failure of an appliance due to lime scale build-up, low
pH, or other chemical imbalance IS NOT covered by the warranty.
The water must be potable, free of corrosive chemicals, sand, dirt,
and other contaminates. It is up to the installer to ensure the water
does not contain corrosive chemicals or elements that can damage
the heat exchanger. Potable water is defined as drinkable water
supplied from utility or well water in compliance with EPA secondary
maximum contaminant levels (40 CFR Part 143.3). If the water contains
contaminants higher than outlined by the EPA, water treatment is
recommended and additional, more frequent maintenance may be
required.
If you suspect that your water is contaminated in any way, discontinue
use of the appliance and contact an authorized technician or licensed
professional.
Water pH between 6.5 and 8.5
•
pH levels below 6.5 can cause an increase in the rate of
corrosion. pH of 8.5 or higher can potentially cause lime scale
build-up
•
Maintain water pH between 6.5 and 8.5. Check with litmus
paper or have it chemically analyzed by a local water treatment
company.
•
If the pH is not between 6.5 and 8.5, consult a local water
treatment company for solutions.
Hardness less than 12 grains (200 mg/L) (Water temperatures
below 140
o
F)
Hardness less than 7 grains (120 mg/L) (Water temperatures of
140
o
F and greater)
•
Hardness levels above the required amounts can lead to lime
scale build-up throughout the system. Water below 5 grains/
gallon (85 mg/L) may be over softened.
•
Consult local water treatment companies for unusually
hard water areas (above the required amounts) or for other
treatment solutions if water is being over softened (below 5
grains/gallon [85 mg/L]).
Chloride concentration less than 100 ppm (mg/L)
•
Do not fill appliance or operate with water containing chlorides
in excess of 100 ppm (mg/L).
•
Using chlorinated fresh water should be acceptable as levels
are typically less than 5 ppm (mg/L).
•
Do not connect the appliance to directly heat swimming pool
or spa water.
