Calentadores de Agua de Refuerzo (a gas)

  • ¿Por qué se instalaría una campana auxiliar para un calentador de agua con reforzador de gas PMG-60 Powermite®?

    Hatco ofrece una campana auxiliar que puede colocarse directamente sobre el PMG-60 para dirigir los gases de combustión hacia la parte posterior del calentador de agua auxiliar (booster). Estos gases pueden canalizarse para su evacuación detrás del mostrador o del lavavajillas, o bien hacia una campana de ventilación o extracción cercana. (Consulte el manual para obtener más detalles).

  • ¿Por qué elegir calentadores de agua de refuerzo a gas?

    La elección es suya. A veces, el costo de la energía hace que los calentadores de agua de refuerzo a gas sean una mejor opción que los eléctricos. Solicite a su representante de Hatco una comparación de costos energéticos.

  • ¿Qué debo hacer con mi calentador de agua de gas con sistema de refuerzo (booster) cuando las temperaturas del aire exterior son extremadamente frías?

    Siempre que sus instalaciones cuenten con calefacción para su habitabilidad, el funcionamiento del PMG-60 no se verá afectado, independientemente de si está encendido o apagado. Los modelos PMG-100 y PMG-200 cuentan con ventiladores de extracción que mantienen el aire caliente fluyendo hacia el exterior a través del conducto de ventilación cuando están encendidos. Por ello, se recomienda mantener la calefacción encendida en todo momento cuando la temperatura exterior sea inferior a 32 °F (0 °C), a fin de contrarrestar la posibilidad —aunque remota— de que entre aire frío en el conducto de ventilación.

  • What should I do about my gas Booster Water Heater when I close down for the winter?

    All main electric and gas services to the Booster Water Heater should shut OFF. The tank and the heat exchanger should be drained of all water to prevent damage from freezing.

  • What is the temperature of the gas Booster Water Heater exhaust?

    Exhaust temperature is approximately 200°F (93°C) at the outlet of the Booster Water Heater. It quickly cools to ambient temperature as it travels through the vent pipe and exits outside or into the room or under a condensate hood.

  • ¿Qué necesito saber si quiero utilizar un calentador de agua de refuerzo a gas a gran altitud (más de 2000 pies [610 m] sobre el nivel del mar)?

    El calentador de agua auxiliar operará por debajo de su capacidad nominal a nivel del mar, ya sea debido a la reducción natural de rendimiento o a la reducción requerida para cumplir con la normativa. Esto significa que se debe verificar el dimensionamiento de la unidad para la altitud prevista. Asimismo, podría ser necesario cambiar el orificio para alcanzar la tasa de combustión máxima permitida. Los manuales incluyen tablas para ayudar a cumplir con los límites de la AGA establecidos para nuestros modelos. Se deben consultar la norma NFPA 54 y las normativas locales para asegurarse de que no prevalezcan sobre estas indicaciones. Existe un kit de orificios sin perforar que ofrece la flexibilidad necesaria para cumplir con las regulaciones de altitud específicas de su instalación.

  • What do I have to know about gas Booster Water Heater ventilation?

    The National Fuel Gas Code NFPA 54 allows all Booster Water Heaters to vent into the room provided that certain overall conditions exist. This is explained in the following excerpt: EXCERPT FROM ANSIZ223.1/NFPA 54 7.2.1 Connection To Venting Systems. Excerpt as permitted in 7.2.2 through 7.2.6, all gas utilization equipment shall be connected to venting systems. 7.2.2 Equipment Not Required To Be Vented. A single booster-type [automatic instantaneous] water heater, when designed and used solely for the sanitizing rinse requirements of a dishwashing machine, provided that the equipment is installed, with the draft hood in place and unaltered, if a draft hood is required in a commercial kitchen having a mechanical exhaust system.

    Where installed in this manner, the draft hood shall not be less than 36" (91 cm) vertically and 6" (15 cm) horizontally from any surface other than the equipment. Where any or all of this equipment is installed so the aggregate input rating exceeds 20 BTU per hour per cubic foot (207 watts per cubic m) of room space in which it is installed, one or more shall be provided with venting systems or other approved means for removing the vent gases to the outside atmosphere so the aggregate input rating of the remaining unvented equipment does not exceed the 20 BTU per hour per cubic foot (207 watts per cubic m) figure. Where the room or space in which the equipment is installed is directly connected to another room or space by a doorway, archway, or other opening of comparable size that cannot be closed, the volume of adjacent room or space shall be permitted to be included in the calculation.

  • Tell me about venting the PMG-100 & PMG-200 Powermite® Gas Booster Water Heater.

    Because the PMG-100 & PMG-200 may add significantly to the equation, the Powermite ® Gas Booster Water Heaters are equipped with an exhaust blower to aid with venting and allow for compliance to NFPA 54.

  • How far can I vent the PMG-60 Powermite® Gas Booster Water Heater?

    The vent hood is approved for a 20 linear foot run. (Note that an elbow is equivalent to five [5] linear feet.) For example: you might place an elbow at the hood exit, run four (4) feet, then place a second elbow behind the warewasher with a six (6) foot vertical vent tube to exit near the condensate hood. This would add up to 20 linear feet.

  • How far can I vent the PMG-100 & PMG-200 Powermite® Gas Booster Water Heater?

    These PMG-100 & PMG-200 are approved for a 40 linear foot run. (Note that an elbow is equivalent to five [5] linear feet of pipe.) Beyond this length, consult a ventilating specialist to provide appropriate means to move the exhaust farther. Booster Water Heater fans are available in the industry that the specialist would be capable of applying.

  • How does your optional Blended Phosphate Water Treatment System work?

    The system stops mineral scale by introducing a measured amount of polyphosphate into the water. The mineral molecules, which have a positive charge, are attracted to the negative charge of the polyphosphate. The mineral molecules are unable to join together, so scale is unable to form.

  • How are the PMG-60, PMG-100 & PMG-200 Powermite® Gas Booster Water Heaters different?

    The PMG-60 was designed primarily for batch-type washers and, because of its low rating, may be allowed to exhaust directly into the room in compliance with NFPA 54. The PMG-100 & PMG-200 models were designed to accommodate conveyor and flight-type washers, as well. Induced draft venting was employed to allow the customer to more readily comply with NFPA 54 when these higher ratings are added to the other appliances in the kitchen.

  • Do you recommend installing a check valve on the inlet side of the Booster Water Heater?

    No, a check valve could potentially create a high-pressure situation that would make the pressure release valve leak.

  • Can the PMG-60 Powermite® Gas Booster Water Heater be vented through a wall?

    No, the PMG-60 is designed to exhaust only into the room in which it is installed where the typical restaurant ventilation system can handle the kitchen atmosphere in accordance with NFPA 54.

  • Can the PMG-60 Powermite® Gas Booster Water Heater be vented outdoors?

    No, the PMG-60 is designed to exhaust only into the room in which it is installed. It is not agency approved for outside venting.

  • Can the PMG-100 & PMG-200 Powermite® Gas Booster Water Heater be vented through a wall?

    Yes, provided the correct thimble or through-the-wall fitting is used for either combustible or non-combustible wall material as it may apply. If this is not an outside wall, then the pipe must continue until it can penetrate an outside wall. Any adjoining room it runs through must be the same temperature as the kitchen.

  • Can the PMG-100 & PMG-200 Powermite® Gas Booster Water Heater be vented outdoors?

    Yes; this can be done horizontally through a wall or vertically through the roof by using the proper approved venting materials. An installer of heating and ventilating equipment will know the AGA acceptable materials and methods to meet NFPA 54 or local equivalent standards. Some helpful suggestions appear in the manuals; however, it is the installer's responsibility to meet the applicable venting system standards.

  • Can anybody install a gas Booster Water Heater?

    Only someone capable and knowledgeable of complying with the National Fuel Gas Code NFPA 54 and/or applicable local code should install a gas Booster Water Heater to provide the highest level of safety, like installers of commercial gas heating and ventilating systems.

  • Are slide mount brackets available in lieu of legs on ALL Booster Water Heaters, and is there an extra charge?

    Slide mounting brackets are available only on Compact Electric Booster Water Heaters because of weight and size limitations. Imperial Electric Booster Water Heaters must be mounted on legs. There is no charge for slide mounting brackets when ordered in lieu of legs. When you order slide mounting brackets, you will not receive legs with your Booster Water Heater.
