SAFETY INFORMATION

Section 2.    Introduction

The MasterTemp

®

 pool heaters are designed and manufactured to provide many years of safe and reliable service when

installed, operated and maintained according to the information in this manual. Throughout the manual, safety warnings and
cautions are identified by the “      “ symbol. Be sure to read and comply with all of the warnings and cautions.

 

WARNING

 —

FOR YOUR  SAFETY

This product must be installed and serviced by a professional service technician, qualified in pool
heater installation. Some jurisdictions require that installers be licensed. Check with your local
building authority about contractor licensing requirements. Improper installation and/or operation
could create carbon monoxide gas and flue gases which could cause serious injury or death. Improper
installation and/or operation will void the warranty.

 

WARNING

 —

This heater is equipped with an unconventional gas control valve that is factory set with a
manifold pressure of -.2 inches wc. 

Improper installation, adjustment, alteration, service or

maintenance can cause property damage, personal injury or loss of life. Installation or service must
be performed by a qualified installer, service agency or the gas supplier. If this control is replaced, it
must be replaced with an identical control.

Do not attempt to adjust the gas flow by adjusting the regulator setting.

 

WARNING

 —

Risk of fire or explosion from incorrect fuel use or faulty fuel conversion. 

Do not try to run a

heater set up for natural gas on propane gas or vice versa. Only qualified service technicians should
attempt to convert heater from one fuel to the other. 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. Serious malfunction of the burner can occur which may result in loss of life. Any additions,
changes, or conversions required in order for the appliance to satisfactorily meet the application
needs must be made by a Pentair dealer or other qualified agency using factory specified and
approved parts. The heater is available for use with natural gas or LP (propane) gas only. It is not
designed to operate with any other fuels. Refer to the nameplate for the type of gas the heater is
equipped to use.

• Use heater only with the fuel for which it is designed.

• If a fuel conversion is necessary, refer this work to a qualified service technician or gas supplier

before putting the heater into operation.

 

WARNING

 —

Risk of fire or explosion from flammable vapors. 

Do not store gasoline, cleaning fluids, varnishes,

paints, or other volatile flammable liquids near heater or in the same room with heater.

 

WARNING —

Risk of explosion if unit is installed near propane gas storage.

 Propane (LP) gas is heavier

than air. Consult local codes and fire protection authorities about specific installation requirements
and restrictions. Locate the heater away from propane gas storage and filling equipment as specified
by the Standard for the Storage and Handling of Liquefied Petroleum Gases, CAN/CSA B149.2
(latest edition) or ANSI/NFPA 58 (latest edition).

 

WARNING —

Risk of fire, carbon monoxide poisoning, or asphyxiation if exhaust venting system leaks.

Only qualified service technicians should attempt to service the heater, as leakage of exhaust
products or flammable gas may result from incorrect servicing.
