    40 PVC pipe, [schedule 80 CPVC for ASME models only]. The Max-E-Therm heater also comes equipped with the Pentair multifunction temperature controller which shows, at a glance, the proper functioning of the heater. All Max-E-Therm heaters are designed with a direct ignition device, HSI (hot-surface ignition), which eliminates the need for a standing pilot.

    Section 1. Introduction CODE REQUIREMENTS Installation must be in accordance with all local codes and/or the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA54 and the National Electrical Code, ANSI/NFPA70 (U.S.), or standards CSA B149 – INSTALLATION CODES FOR GAS-BURNING APPLIANCES AND EQUIPMENT and/or local codes and Standard CSA C22.1 – Canadian Electrical Code, Part 1 (Canada).

  • Page 6: Save These Instructions

    If used outdoors, install far from open windows, doors, vents and other openings. Pentair strongly recommends that all vents, pipes and exhaust systems be initially and periodically tested for proper operation. This testing can be accomplished by using a hand-held carbon monoxide meter and/or by consulting with a gas professional.
  • Page 7 Do not attempt to alter the rated input or type of gas by changing the orifice. If it is necessary to convert to a different type of gas, consult your Pentair dealer.

  • Page 8: General Specifications

    Section 1. Introduction GENERAL SPECIFICATIONS NOTICE: • Combustion air contaminated by corrosive chemical fumes can damage the heater and will void the warranty. • The Combination Gas Control Valve on this heater differs from most appliance gas controls. If it must be replaced, for safety reasons replace it only with an identical gas control.

    Section 2. Installation Installation Instructions HEATER DESCRIPTION Figure 1 is a diagram of the heater showing how it operates. Precisely matched orifice plates meter the air and gas into the mixer. The blower draws the air and gas through the mixer and forces it into the burner’s flame holder.

  • Page 10: Specifications

    Section 2. Installation SPECIFICATIONS These installation instructions are designed for use by qualified personnel only, trained especially for installation of this type of heating equipment and related components. Some states require installation and repair by licensed personnel. If this applies in your state, be sure your contractor bears the appropriate license. See Figure 2 for Outdoor and Indoor Installations.

  • Page 13: Gas Connections

    Section 2. Installation GAS CONNECTIONS GAS LINE INSTALLATIONS Before installing the gas line, be sure to check which gas the heater has been designed to burn. This is important because different types of gas require different gas pipe sizes. The rating plate on the heater will indicate which gas the heater is designed to burn.

    Then within a short distance of the pool heater, generally around 24 inches, they will install a second regulator, which is the second stage. This second stage regulator would be set at the minimum operating pressure for the heater. For “Natural Gas Pentair Pool Heaters” the minimum is 7 inches W.C. See “Gas Pressure Requirement Charts”...

  • Page 15: Testing Gas Pressure/Gas Pressure Requirements

    Section 2. Installation TESTING GAS PRESSURE Before operating the heater, the heater and its gas connections must be leak tested. Do NOT use an open flame to test for leaks. Test all gas connections for leaks with soapy water or another non-flammable method (see page 14). The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

  • Page 16: Outdoor Installation

    Section 2. Installation OUTDOOR INSTALLATION (U.S. and Canada) For heaters located outdoors, using the built-in stackless venting system. WARNING Risk of explosion if a unit burning propane gas is installed in a pit or other low spot. Propane is heavier than air. Do not install the heater using propane in pits or other locations where gas might collect.

    Section 2. Installation OUTDOOR SHELTER INSTALLATION In Canada, this pool heater can only be installed outdoors or in an enclosure that is not normally occupied and has no direct openings into occupied areas. WARNING Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly when installing heater. Do not use a draft hood with this heater, as the exhaust is under pressure from the burner blower and a draft hood will allow exhaust fumes to blow into the room housing the heater.

    CHEMICAL BALANCE POOL AND SPA WATER Your Pentair pool heater was designed specifically for your spa or pool and will give you many years of trouble-free service, provided you keep your water chemistry in proper condition. Water chemistry should follow good swimming pool water chemistry practices. When using a chlorinator, install it down stream from the heater and at a lower level than the heater outlet.

  • Page 48: Chemical Balance

    Section 5. Maintenance CHEMICAL BALANCE, (cont’d.) It is wise to test pool water regularly. Never allow chlorine residual to drop below 0.6 ppm (parts per million). The minimum level for effective chlorine or bromine residual is 1.4 ppm. pH - The term pH refers to the acid/alkaline balance of water expressed on a numerical scale from 0 to 14.
