Print Form Typical Specification for Heat Transfer Phoenix Evolution Guide Specification Sheet PHOENIX EVOLUTION Models: PHE-130-55/199-55 PHE-130-80/199-80 PHE-130-119/199-119 The Phoenix Evolution Heater shall be manufactured by Heat Transfer Products, Inc. with identification of model number PHE -___________________. The heater shall be a sealed combustion system, taking only outside air for combustion and exhausting the flue gas with PVC Schedule 40 or 80 PVC or CPVC . The heater and all related gas piping shall be approved for zero clearance to any combustible surfaces. The heaters total combined equivalent venting length, including fitting allowances for both the intake air and exhaust gas shall not exceed 85' (in the units native size as manufactured and stated on the units model product data sheet) in 2", or 3" pipe or 125' for the next size up for longer vents using 3" or 4" from the heaters location. The heaters tank shall be constructed of 316L stainless steel. The primary condensing heat exchanger shall be constructed 5" diameter ¼" thick wall with 90/10 cupronickel tube. The secondary heat exchanger shall be constructed of 800H stainless steel and 90/10 cupronickel. The tank insulation shall be water blown foam 2" thick in the side wall with a rating of R14.2 and 3" thick in the top with a rating of 21.3. Insulation shall be enclosed in a plastic jacket on the sides as well as the top and bottom. All components shall be accessible and serviceable. All related hardware shall be constructed of stainless steel studs with brass nuts on the burner mounting flange for future serviceability. All water connection nipples shall be constructed of stainless steel and be attached to the side of the tank. The top and bottom of the tank shall be smooth with no pipe tapings on the top or legs on the bottom. The unit shall be equipped with a pre-plumbed Hydronic Heating Module which is connected directly to the tank through dip tubes that draw water from the top and return water to the bottom of the tank. The heating module has a brazed plate exchanger which transfers the energy from the storage tank into the central heat water which is circulated through the other side of the brazed plate. The heating module is equipped with a modulating pump to control the btu input into the braze plate and to control the outlet temperature feeding the heating circuits. The Total System Control manages the storage tank temperature and the modulating pump flow rate to optimize the performance and increase the systems overall efficiency. The Outdoor Sensor is used to provide feedback to the control to adjust the central heating target set point to meet the system design. The Hydronic Heating Module will have isolation valves to assure brazed plate exchanger can be serviced without decommissioning the entire heating system. The heat module will have flexible stainless lines and isolation valves so the entire assembly can be removed without draining the water side of the storage tank. Phoenix Evolution Solar shall be a bi-valent design, separating the solar heat exchanger in the bottom portion of the storage tank and combustion heat exchanger and hydronic heating module located on the top portion of the tank. Solar energy will be transfer from the bottom heat exchanger with heat rising to the top of the storage tank optimizing the suns energy to transfer into the storage tank. If the energy delivered from the solar system is greater than the energy absorbed by the Hydronic Heating module or domestic hot water demand, the Total System Control will not fire the burner until storage tank target set point is no longer being met . The heater shall be UL/ULC/SRCC listed and will exceed the minimum efficiency requirements of ASHRAE 90.1 b-2007. All heaters shall be approved in accordance with ANSI Z-21.10.3. All heaters will be supplied with a factory installed ASME rated temperature and pressure relief valve for the storage tank. The Hydronic Heating Module shall be equipped with a pressure relief valve equipped to handle the maximum rate of the hydronic heating module. All heaters will be supplied with a factory installed low water cutoff and upper hot water sensor and lower cold water sensor. All heaters shall be furnished with factory installed condensation trap assembly ready for easy connection to a field supplied condensation drain. LP-327 Rev 12-11-09
