HTP.) In addition, local authorities may require a condensate neutralizer to neutralize the condensate. Condensate neutralizers are made up of lime crystals, marble or phosphate chips. Neutralizers can be installed in the field by the installer and purchased from HTP (p/n 7450P-212).
A. BEFORE LOCATING THE HEATER Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the heater installation location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or death.
C. CLEARANCES FOR SERVICE ACCESS Figure 1 – Minimum Service Clearances NOTE: If you do not provide the minimum clearances shown in Figure 1, it might not be possible to service the heater without removing it from the space. The space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space as the heater.
1. DIRECT VENT INSTALLATION OF EXHAUST VENT AND INTAKE PIPE If installing a direct vent option, combustion air must be drawn from the outdoors directly into the water heater intake, and exhaust must terminate outside. There are three basic direct vent options detailed in this manual: 1. Side Wall Venting, 2. Roof Venting, and 3. Unbalanced Venting.

Chemical imbalance of the water supply may affect efficiency and cause severe damage to the water heater and associated equipment. HTP recommends having water quality professionally analyzed to determine whether it is necessary to install a water softener. It is important that the water chemistry on both the domestic hot water and central heating sides are checked before installing the water heater, as water quality will affect the reliability of the system.

EXPANSION TANK AND MAKE-UP WATER 1. Ensure that the expansion tank is sized to correctly handle heater and system water volume and temperature. Undersized expansion tanks cause system water to be lost from the relief valve, causing make-up water to be added. Eventual heater failure can result due to excessive make-up water addition.
H. PIPING DIAGRAMS Figure 4 – Phoenix With Air Handler - NOTES: 1. Minimum pipe size should match unit connection size. Upsize pipe accordingly if greater flow is required. 2. A thermal expansion tank suitable for potable water must be sized and installed within this piping system between the backflow preventer and the cold water inlet.

The standard unit does not meet the required temperature settings for sanitizer booster applications. Use only the Phoenix Sanitizer Booster that delivers temperatures of 184 F. Inlet water to the booster must be supplied at 140 Figure 10 - Phoenix Sanitizer Booster Installation – PH130-55SA / PH199-55SA - LP-179-SA NOTES: 1.
PART 5 – VENTING, COMBUSTION AIR AND CONDENSATE REMOVAL The heater must be vented as detailed in this Venting Section. Ensure exhaust vent and intake piping complies with these instructions regarding vent system. Inspect finished exhaust vent and intake piping thoroughly to ensure all joints are well secured, airtight, and comply with all applicable code requirements, as well as with the instructions provided in this manual.
When installing AL29-4C vent piping, install a PVC-to-stainless adapter at the heater vent connection, and at the termination when using an HTP PVC termination kit. DO NOT mix AL-29-4C piping from different manufacturers unless using adapters specifically designed for the purpose by the manufacturer.

CONCENTRIC VENTING THROUGH AN EXISTING SYSTEM NOTE: The following instructions refer only to venting through an existing vent system, and not to venting with HTP’s concentric vent kits. Refer to Concentric Vent Kit installation manual (LP-166) for further concentric venting information and instructions.

If the heater condensate outlet is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from HTP). If required by local authorities, a condensate filter of lime crystals, marble, or phosphate chips will neutralize slightly acidic condensate.
The heater has the capability of an outdoor reset. Connecting an outdoor sensor allows the heater to operate at optimum efficiency. HTP offers an outdoor sensor, p/n 7250P-319. The outdoor sensor must be a 12K NTC sensor. Use a minimum 22 AWG wire for runs of 100 feet or less and minimum 18 AWG wire for runs up to 150 feet.
PART 7 – GAS CONNECTIONS Failure to follow all precautions could result in fire, explosion, severe injury or death! The gas supply shall have a maximum inlet pressure of less than 14" water column (350 mm), ½ pound pressure (3.5 kPa), and a minimum of 3.5"...
Figure 25 – Gas Valve LP-179-P Do not do a gas conversion on this water heater without an officially approved conversion kit and instructions supplied by HTP. Failure to use a conversion kit when converting the heater to fire on Natural or LP gas will result in extremely dangerous burner operation, leading to fire, explosion, severe injury or death.

(If the switch is not functioning properly, replace it. 1. Check line voltage. Must be between 100 – 128 volts. 2. If available, connect a PC and, using HTP service software, check the 24v supply display in the lower left corner of the screen. The number displayed must be greater than 128 and should be greater than 250.

F01, follow the troubleshooting guide for that code. 7. If the flue temperature increases to over 190 F, consult HTP for further assistance. Interrupted or shorted 1. Check the electrical connection to the appropriate temperature sensor.
PART 11 - MAINTENANCE In unusually dirty or dusty conditions, care must be taken to keep water heater cabinet door in place at all times. Failure to do so VOIDS WARRANTY! Allowing the water heater to operate with a dirty combustion chamber will hurt operation. Failure to clean the heat exchanger as needed by the installation location could result in water heater failure, property damage, personal injury, or death.
