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).
PART 3 – PREPARE WATER HEATER LOCATION Carefully consider installation when determining heater location. Please read the entire manual before attempting installation. Failure to properly take factors such as heater venting, piping, condensate removal, and wiring into account before installation could result in wasted time, money, and possible property damage and personal injury.
Do not install the water heater in a well, stairwell, alcove, courtyard, or other recessed area. Do not install the water heater on stack frames. In areas where heater is exposed to sustained temperatures below 32 F, provisions must be made to protect the water heater, condensate lines, and piping from freezing.
Figure 2 – Minimum Service Clearances NOTE: If you do not provide the minimum clearances shown in Figure 2, 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 water heaters located in the same space as the heater.
Vents must be properly supported. Heater exhaust and intake connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the heater and the balance at 4’ intervals. Heater must be readily accessible for visual inspection for the first 3’...
Do not attempt to vent this water heater by any means other than those described in this manual. Doing so will void the warranty, and may result in severe personal injury or death. E. PREVENT COMBUSTION AIR CONTAMINATION Install intake piping for the heater as described in the Venting Section. Do not terminate exhaust in locations that can allow contamination of intake air.
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.

PART 5 – VENTING, COMBUSTION AIR AND CONDENSATE REMOVAL The heater must be vented as detailed in this Venting Section. Ensure exhaust 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.
You must not use “B” vent in an exhaust application. “B” vent is for intake applications ONLY. Using “B” vent in an exhaust application will result in serious injury or death. D.

3. INDOOR COMBUSTION AIR INSTALLATION IN CONFINED OR UNCONFINED SPACE This heater requires fresh, uncontaminated air for safe operation and must be installed in a mechanical room where there is adequate – Contaminant Table combustion and ventilating air. NOTE: To prevent combustion air contamination, see Table 1 Combustion air from the indoor space can be used if the space has adequate area or when air is provided through a duct or louver to supply sufficient combustion air based on the water heater input.
4. OUTDOOR INSTALLATION When drawing combustion air from the outdoors, care must be taken to provide adequate freeze protection. Failure to do so could result in property damage and premature product failure. Such damages and failures ARE NOT covered by product warranty. This water heater is designed to draw combustion air through the louver system in the front of the heater cabinet.
Figure 17 Figure 18 H. CONDENSATE REMOVAL SYSTEM NOTE: Check with your local gas company to determine if combustion condensate disposal is permitted in your area. In the state of Massachusetts, condensate must be neutralized before entering a drain. This condensing high efficiency water heater has a condensate removal system. Condensate is water vapor derived from combustion products, similar to that produced by an automobile when it is initially started.
Page 35
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.
PART 6 – WIRING To avoid electrical shock, turn off all power to the heater prior to opening an electrical box within the unit. Ensure the power remains off while any wiring connections are being made. Failure to follow these instructions could result in component or product failure, serious injury, or death.
PART 7 – GAS CONNECTIONS Failure to follow all precautions could result in fire, explosion, severe injury or death!
