HTP SSC-80 Installation Manual

This water heater is certied for indoor use only. DO NOT
INSTALL OUTDOORS. Outdoor installations ARE NOT covered
by warranty.
Choose a location for the water heater as centralized to the
piping system as possible. Also, locate the water heater and
domestic water piping where it will not be exposed to freezing
temperatures. All piping should be insulated. Additionally, place
the water heater so that the drain, controls, and inlets/outlets
are easily accessible.
NOTE: To save on heating costs and improve energy eciency
keep the distance between the boiler and water heater to a
minimum to reduce heat loss from excess piping and keep
friction loss at a minimum. Ensure all piping between the boiler
and water heater is properly insulated to minimize heat loss.
The water heater may be located some distance from the boiler
provided the circulator meets ow requirements through the
coil. The greater the distance from the water heater to the boiler
the longer the response will be to a call for hot water.
This water heater must be installed vertical on a level surface.
NOTE: In the State of California, the water heater must be
braced, anchored, or strapped to avoid moving during an
earthquake. Contact local utilities for code requirements in your
area. Visit http://www.dsa.dgs.ca.gov or call 1-916-445-8100
and request instructions.
However, applicable codes shall govern installation. For
residential water heaters of a capacity greater than 52 gallons,
consult the local building jurisdiction for acceptable bracing
procedures.
NOTE: If you do not provide the minimum clearances shown
in Figure 1, it might not be possible to service the water heater
without removing it from the space.

Clearances
Ensure the location can support the entire lled weight of the
water heater. Failure to properly support the water heater could
result in property damage, severe personal injury, or death.
This water heater must not be located near ammable liquids
such as gasoline, butane, liqueed propane, adhesives, solvents,
paint thinners, etc., as the controls of this water heater could
ignite these vapors and cause an explosion resulting in property
damage, severe personal injury, or death.
B. Performance and Sizing Guidelines
NOTE: The table below describes the minimum BTU/H required
to achieve the listed rst hour rating. The mass of the boiler will
aect recovery time. More boiler mass equals longer recovery
time.

C. Anode Rod
This water heater is equipped with a magnesium anode rod.
Anode rods are sacricial components that counteract water
chemistry to minimize or eliminate tank corrosion.
The anode rod should be inspected annually and replaced as
necessary to prolong tank life. Have the supply water quality
professionally analyzed, as local water conditions will inuence
the duration for inspection and replacement of the anode rod.
The use of a water softener may increase the speed of anode
consumption. More frequent inspection of the anode is needed
when using softened or treated water.
Water with high sulfate and/or mineral content can produce a
rotten egg odor in heated water. Chlorinating the water supply
may minimize this problem.
NOTE: Failure of a heat exchanger due to lime scale build-up on
the heating surface, low pH, or other imbalance IS NOT covered
by the warranty.
NOTE: Do not remove the anode rod from an operating water
heater. Operating the water heater without the anode rod will
shorten the life of the tank and VOID the warranty.
D. Water Chemistry Requirements
Outlined below are water quality parameters that need to be
met in order for the system to operate eciently for many
years.
Water Hardness
Water hardness is mainly due to the presence of calcium and
magnesium salts dissolved in water. The concentration of
these salts is expressed in mg/L, ppm, or grains per gallon as
a measure of relative water hardness. Grains per gallon is the
common reference used in the US water heater industry.
Hardness expressed as mg/L or ppm may be divided by 17.1 to
convert to grains per gallon. Water may be classied as very
