Installation

X

Receiving
  Verify there is no physical damage to unit case that would indicate possible damage to internal components. Review Installation instructions and plumbing diagram to verify proper installation.
X

Verify to assure
  Specified clearances and service access. Front cover must have clear access or warranty is voided.
  Adequate room size to conform to the National Fuel Gas Code requirements for make-up air for an unvented booster (Model PT-56 only). The unit must not be installed in a closed utility room with no makeup air.
  That the approved flue pipe is directed into dish hood or out of building as required by the National Fuel Gas Code or local code requirements (Model PT-200). Vent pipe should be properly supported and not exceed 70’ in length for 4” pipe and 40’ for 3” pipe (each 90° elbow adds 10' to pipe length, refer to installation manual for details). If the unit is vented to the outside, be sure flue terminus does not allow backdraft of cold air that could cause freezing. Verify the ventilation system is adequate for sufficient make up air.
  Access to electrical and plumbing hookups and installation of all peripherals including temperature gauges, pressure gauges, gate or ball valves, shock absorber, pressure reducer and temperature and pressure relief valves.
 

Verify that voltage, gas type, pressure and pipe size is adequate in relation to its length and number of elbows.
  Verify gas supply type, pressure and pipe size is adequate in relation to its length and number of elbows
  Verify that the all parts of the easy install kit have been installed, including (Refer to plumbing diagram)
X

Verify that the easy install kit is installed, including
  A ball or gate valve installed on the water inlet.
  Temperature and Pressure gauges, PT-56 & PT200RC only, are installed on inlet and outlet of booster (PT-200 has built-in digital temperature gauge).
  Pressure regulator is installed on OUTLET of booster heater (PT-56 MUST have regulator
on outlet) and set to 20 PSI during rinse cycle. If there is a pressure reducer installed on
the dish machine, none should be installed with the booster (refer to installation
manual). Only one pressure regulator should be installed in the system.
  Water bypass is installed per plumbing installation drawing.
  Legs are leveled so that power vent outlet stays aligned with flue outlet pipe and the front
cover installs and fits properly.
  110 VAC power cords are plugged tightly into DC power supplies inside case.
X

Verify plumbing and related componets to assure
  Verify inlet water is at recommended temperature for dish machine being used (not to exceed 140ºF) and is connected to the inlet connection.
  Verify the hot water outlet pipe is connected to the outlet of the booster heater and does not exceed 5 feet in length to comply with NSF-5 recommendations. (Must be re-circulated if over five feet.) Verify correct plumbing layout using piping diagrams supplied, flow through or re-circulating.
  Verify nothing is blocking combustion air inlet at bottom of PT-56 or right side of PT-200. Verify that there is no floor drain under the combustion air intake of the PT-56 & PT-200. This will void warranty.
  Combustion air can be brought from outside of the building on a PT-200, but this is not recommended.
  Check all water connections for leaks and that they are connected to proper fittings.
  Check all gas connections for leaks. Be sure gas union inside case is tight after installation. Again, verify that the gas line is properly sized for its length and number of elbows.
  Verify there are no cold water bypasses in plumbing system.
  DON’T EVEN THINK OF TURNING ON THE POWER TO THE BOOSTER HEATER UNTIL THE SYSTEM IS FILLED WITH WATER AND ALL AIR IS PURGED. THIS WILL CAUSE SEVERE DAMAGE THAT WILL IN NO WAY BE COVERED UNDER WARRANTY. THE START UP CANNOT BE DONE WITHOUT WATER. DON’T INSTALL BOOSTER WITHOUT WATER. Have the PT200 Service Manual available when performing Start-Up.
X

START-UP
  With the power and gas turned off, run dish washer through 3 cycles to fill booster heater with water
and purge all air from the system. Check for any leaks at this time.
  Turn power switch on and verify that the green LED is flashing, and make sure no red LED service
codes are flashing.
  Verify that all air has been purged from the gas line. Purge if necessary.
  Turn on gas supply including shut off valve in booster heater case.
X

PT-56 and PT-200-RC (Recirculating)

  Turn off power to unit.
  Take front cover off of unit, turn power switch to on. Burner should fire up in low burn and immediately
ramp up to high burn. If burner does not light on first attempt, cycle power off and on until it does. All air
should now be purged from gas line. 
  When water in tank approaches set temperature, burner relight fairly quickly until tank is at operating temperature.
X

Run dish machine through wash cycle and verify 
  Rinse water pressure is at 20 PSI at dishwasher gauge during rinse cycle  
  Inlet water temperature to booster heater is at least 120ºF.
  Outlet temperature of booster heater is at least 180ºF.
  After running dish washer at full capacity for at least eight cycles it maintains at least 180ºF outlet temperature.
X

PT-200-FT (Flow through)
  With front cover removed, turn power switch to on. Only green LED should be flashing. Burner should remain off.
  Lock dish machine rinse on. This can usually be done by turning a rack upside down at rinse cam.
X

Verify:  
  The fan on the booster activates, followed by the burner ignition at low burn  
  Burner immediately ramps to high burn.
  Rinse water pressure is at 20 PSI on the dish washer gauge during rinse cycle. Verify the GPM flow rate by counting the green light flashes between pauses (refer to Service Manual SB-13) when the rinse is operating.
  Inlet water temperature to booster heater is at least 120ºF, and does not exceed 140ºF.
  Push the white button on the digital display for inlet water temperature while display is
operational.
  Outlet water temperature of booster heater maintains at least 180ºF and not more than
195°.
  That after running dish washer at full capacity for at least eight racks, it maintains an outlet
temperature of at least 180ºF.
  When rinse is turned off, the booster shuts down.
