PART 1 – GENERAL SAFETY INFORMATION

A. PRECAUTIONS

This water heater is approved for indoor installations only. Clearance to combustible materials: 0” top, bottom, sides and back. Heater must have room for service: 24” front and 6” sides are minimum recommended service clearances. (A combustible door or removable panel is acceptable front clearance.) This water heater has been approved for closet installation, and installation on combustible flooring. Do not install this water heater directly on carpeting.

LP-65 Rev. 3.24.14

NOTE: If the heater is exposed to the following, do not operate until all corrective steps have been made by a qualified serviceman:

1. FIRE

2. DAMAGE

3. WATER Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.

High heat sources (sources generating heat 100oF / 37oC or greater, such as stove pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is recommended to keep a minimum clearance of 8” from high heat sources. Observe heat source manufacturer instructions, as well as local, state, provincial, and national codes, laws, regulations and ordinances when installing this water heater and related components near high heat sources.

UNCRATING HEATER – Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.

COLD WEATHER HANDLING – If the heater has been stored in a very cold location (BELOW 0oF) before installation, handle with care until the plastic components come to room temperature.

DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN UNDERWATER. Immediately call a qualified service technician. Replace any part of the control unit that has been under water.

B. WHEN SERVICING THE WATER HEATING SYSTEM

 To avoid electric shock, disconnect electrical supply before performing maintenance.  To avoid severe burns, allow heater to cool before servicing.

C. HEATER WATER

 Do not use petroleum-based cleaning or sealing compounds in a water heating system. Gaskets and seals in the system may

be damaged. This can result in substantial property damage.

 Do not use “homemade cures” or “heater patent medicines”. Damage to heater, substantial property damage, and/or serious

personal injury may result.

PART 2 – PREPARE THE WATER HEATER

Remove all sides of the shipping crate to allow the heater to be moved into its installation location.

A. SPECIFICATIONS AND PERFORMANCE RATINGS

Figure 1 – Specifications and Dimensions

B. PERFORMANCE AND SIZING GUIDELINES

Determine the amount of domestic hot water needed, then use the chart below to optimize water heater against boiler sizing.

Table 1

LP-65 Rev. 3.24.14

Locate the water heater where any leakage from the relief valve, related piping, tank, or connections will not result in damage to surrounding areas or lower floors of the building. The water heater should be located near a floor drain, or installed in a drain pan. HTP WILL NOT be held liable for leakage damages.

This water heater must not be located near flammable liquids such as gasoline, butane, liquefied propane, adhesives, solvents, paint thinners, etc., as the controls of this water heater could ignite these vapors and cause an explosion, resulting in property damage, severe personal injury, or death.

NOTE: Above chart is based on boiler size conforming to the minimum BTU/H required to achieve first hour ratings. The mass of the boiler will affect recovery time. More boiler mass equals longer recovery time.

C. LOCATING THE WATER HEATER

This water heater is certified for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty. Choose a location for the water heater as centralized to the piping system as possible. Also, locate the water heater and domestic

water piping where it will not be exposed to freezing temperatures. All piping should be insulated. Additionally, place the water heater so that the drain, controls, and inlets/outlets are easily accessible.

This water heater must be installed vertical on a level surface.

Figure 2

If you do not provide the minimum clearances shown, it might not be possible to service the heater without removing it from the space.

D. ANODE ROD

This water heater is equipped with a magnesium anode rod. Anode rods are sacrificial components that counteract water chemistry to minimize or eliminate tank corrosion.

The anode rod should be inspected annually and replaced as necessary to prolong tank life. Have the supply water quality professionally analyzed, as local water conditions will influence the duration for inspection and replacement of anode rod.

The use of a water softener may increase the speed of anode consumption. More frequent inspection of the anode is needed when using softened or treated water.

Water with high sulfate and/or mineral content can produce a rotten egg odor in heated water. Chlorinating the water supply may minimize this problem.

NOTE: Failure of a heat exchanger due to lime scale build-up on the heating surface, low pH or other imbalance IS NOT covered by the warranty.
