SPECIFICATION FOR DOMESTIC WATER HEATERS
Power Combustion, Gas/Oil Fired Water Heaters with Polymer-Lined Storage Tanks
Furnish and install TURBOPOWER® gas/oil water heater(s) as manufactured by PVI Industries, L.L.C.
of Fort Worth, Texas. Supply quantities and model numbers as indicated on the plumbing schedule.
Gas and Electrical Consumption
The water heater will operate at a minimum of 83% thermal efficiency when tested by an inde pendent laboratory to
ANSI Z21.10.3. The water heater will comply with paragraph 7.2.4.4, the thermal efficiency, the standby loss, and all
other requirements of ASHRAE 90.1-1999.
Pressure Vessel and Heating Surfaces
The water heater will be constructed and stamped in accordance with Section IV, Part HLW of the ASME code.
The storage section of the water heater will be National Board Registered for a working pressure of ____ 125 psi
(standard) or ____ 150 psi and will be pressure tested at 1-1/2 times working pressure. The heatin g section of the water
heater will be National Board Registered for a working pressure of 150 psi and will be pressure tested at 1-1/2 times
working pressure.
The heat exchanger will be a firetube design with the combustion chamber and al l heating surfaces completely
water-backed. The fireside of the combustion chamber will be of boiler-grade steel. The waterside of the combustion
chamber will be non-ferrous. The fire tubes will be solid copper. The heating surfaces will be removable by unbolting
from the pressure vessel, allowing 100% access to waterside surfaces. The tank will be accessible in the field through a
manway sized opening, allowing access to 100% of interior surfaces. All tank connection fittings will be nonferrous and
removable from the tank.
Tank Lining
The entire
be applied only after the tank is completely fabricated and all welding is completed.
be a thermoplastic polymer that is NSF 61 approved and consist of FDA compliant materials.
have a dielectric resistance of 1600 volts per mil.
The lined tank will not require anode r ods and none will be used. Water heaters that use anode rods in a vessel that
contains non-ferrous heating surfaces will not be acceptable.
Combustion will be provided by a forced-draft power burner with a gas and oil train meeting the following agency
requirement for the input specified:
___ UL (standard) ___ FM ___ IRI ___ Other ______________________
lining will:
consist of multiple applications creating a continuous and nonporous barrier with no interruptions or
discontinuities, particularly at the tank-to-fitting transitions.
be confirmed after all welding is completed to be 100% void-free by the ASTM D-5162 wet electrode standard.

Safety Controls
As a minimum
• electronic flame safeguard with pre-purge (600,000 to 3,200,000 Btu/h burners)
• two immersion operating thermostats
• an immersion temperature limiting device
• an ____ ASME or ____ AGA-rated temperature and pressure relief valve
• and options as selected on form PV 6000
Storage tank: _____ year (5 standard, 15 optional) Covers manufacturing or material defects,
leaks and /or the production of rusty water. T ank coverage will include failure due
to scale buildup for ____ full years (3 standard, 6 optiona l) and ____ prorated years
(2 standard, 9 optional) with no provision or cond ition for maintenance or
inspections and no limitations on water chemistry.
Heat exchanger
and combustion chamber: 5 year. Covers manufacturing or material defects, leaks, and/or the
production of rusty water.
Burner and all heater parts: 1 year
The heater will have a _____ first year or ____ long-life service policy, which will cover replacement labor and freight
costs under certain conditions. Initiation and /or continuation of warranty coverage will not
inspections, regular replacement of anode rods, or water chemistry. Complete copies of all warranties and service
policies, including all exclusions and conditions, will be presented to the owner as part of the submittal package. These
summaries are not warranties. Consult warranty and policies for full details.
The storage and heating sections will be completely factory packaged, requiring only job site hookup to utilities,
venting, and plumbing. The heater will be insulated, jacketed with enameled steel panels, and mounted on heavy-duty
channel skids. The heater will fit properly in the space provided and installation will conform to all local, state, and
national codes.
Start up on the unit will be performed by factory trained and authorized personnel. A copy of the start up report will
be provided to the owner.
, the heater will be equipped with the following:
