Part 1 - General Safety Information

This water heater is approved for indoor installations only and is not intended for use as a pool heater. Clearance to combustiblematerials:0”top,bottom,sides,andback.Heater musthaveroomforservice:24”front,6”top,and6”sidesare 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 directly on carpeting. Install the water heater in a location where temperature and pressure relief valve discharge or a leak will notresultindamagetothesurroundingarea.Ifsuchalocation isnotavailable,installanauxiliarycatchpan.

Installer - Readallinstructionsinthismanualbeforeinstalling. Performstepsinthegivenorder.

User - This manual is for use only by a qualified heating installer/servicetechnician.Havethiswaterheaterserviced/ inspectedannuallybyaqualifiedservicetechnician.

FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE,

SEVERE PERSONAL INJURY, OR DEATH.

3.Water

Failure to follow this information could result in property damage,severepersonalinjury,ordeath.

DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician. The water heater MUST BE replaced if it has been submerged. Operating a previously submerged waterheatercouldresultinpropertydamage,severepersonal injury,ordeath.

NOTE: Water heater damage due to flood or submersion is consideredanActofGod,andISNOTcoveredunderproduct warranty.

NOTE: Obey all local codes. Obtain all applicable permits beforeinstallingthewaterheater.

NOTE: Install all system components and piping in such a manner that does not reduce the performance of any fire ratedassembly.

High heat sources (sources generating heat 100oF / 37oC or greater,suchasstovepipes,spaceheaters,etc.)maydamage plastic components of the water heater as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty.Itisrecommendedtokeepaminimumclearanceof 8”fromhighheatsources.Observeheatsourcemanufacturer instructions, as well as local, state, provincial, and national codes, laws, regulations and ordinances when installing this waterheaterandrelatedcomponentsnearhighheatsources. Do not use this water heater for anything other than its intended purpose (as described in this manual). Doing so could result in property damage and WILL VOID product warranty.

UNCRATING THE WATER HEATER - Any claims for damage or shortage in shipment must be filed immediately against the transportationcompanybytheconsignee.

A. When Servicing the Water Heating System

Be sure to disconnect electrical power before performing service.Failuretodosocouldresultinelectricalshock,property damage,seriouspersonalinjury,ordeath.

NOTE: When inquiring about service or troubleshooting, reference the model and serial numbers from the water heater ratinglabel.

To avoid severe burns, allow water heater and associated equipmenttocoolbeforeservicing.

Avoidcontinuouslyhighlevelsofhumidity

Nevercloseexistingventilationopenings

NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to make note of the water heater model and serialnumber.

Theservicelifeofthewaterheater’sexposedmetallicsurfaces, such as the junction box, is directly influenced by proximity to damp and salty marine environments. In such areas higher concentration levels of chlorides from sea spray coupled with relative humidity can lead to degradation of water heater components.

Incorrect operating conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the installation location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or death. Failure of the water heater or components due to incorrect operating conditions IS NOT coveredbyproductwarranty.

2.Choose a location for the water heater as centralized to the piping and electrical 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,placethewaterheatersothatthedrain,controls, andinlets/outletsareeasilyaccessible.

Figure 1 - Recommended Service Clearances - NOTE: Overhead View Not Representative of All Models

NOTE: Tosaveonheatingcosts andimproveenergyefficiency keep the distance between the water heater and fixtures to a minimum to reduce heat loss from excess piping and keep friction loss at a minimum. Ensure all water heater piping is properlyinsulatedtominimizeheatloss.

NOTE: If you do not provide the minimum clearances shown in Figure 1, it might not be possible to service the water heater withoutremovingitfromthespace.
