Turbotemp 125 Pool and Spa Heater Installation and User’s Guide

CONSUMER INFORMATION AND SAFETY

The Consumer Product Safety Commission warns that elevated water temperature can 
be hazardous. See below for water temperature guidelines before setting temperature.

!

WARNING

1. Spa or hot tub water temperatures should never exceed 40° C (104° F). A temperature of 

38° C (100° F) is considered safe for a healthy adult. Special caution is suggested for young 
children.

2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness 

which could lead to unconsciousness and subsequently result in drowning.

3. Pregnant women beware! Soaking in water above 39° C (102° F) can cause fetal damage 

during the first three months of pregnancy (resulting in the birth of a brain-damaged or 
deformed child). Pregnant women should stick to the 38° C (100° F) maximum rule.

4. Before entering the spa or hot tub, the user should check the water temperature with an 

accurate thermometer. Spa or hot tub thermostats may err in regulating water temperatures 
by as much as 2.2° C (4° F).

5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood 

pressure problems should obtain their physician’s advice before using spas or hot tubs.

6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or 

anticoagulants should not use spas or hot tubs.

The Consumer Product Safety Commission warns that carbon monoxide is an “invisible 
killer”. Carbon monoxide is a colourless and odorless gas.

!

WARNING

!

DANGER

1. Carbon monoxide is produced by burning fuel, including natural gas and propane.
2. Proper installation, operation and maintenance of fuel-burning appliances in the home is the 

most important factor in reducing carbon monoxide poisoning.

3. Be sure that fuel burning appliances such as heaters are installed by professionals according 

to manufacturer’s instructions and codes.

4. Always follow the manufacturer’s directions for safe operation.
5. Have the heating system (including vents) inspected and serviced annually by a trained 

service technician.

6. Examine vents regularly for improper connections, visible cracks, rust or stains.
7. Install battery-operated carbon monoxide alarms. The alarms should be certified to the 

requirements of the most recent UL, IAS, CSA and IAPMO standard for carbon monoxide 
alarms. Test carbon monoxide alarms regularly and replace dead batteries.

GENERAL SPECIFICATIONS

NOTICE:

• Combustion air contaminated by corrosive chemical fumes can damage the heater and 

will void the warranty.

•  The  Combination  Gas  Control  Valve  on  this  heater  differs  from  most  appliance  gas 

controls. If it must be replaced, for safety reasons replace it only with an identical gas 
control.

• The access door panels must be in place to provide proper ventilation. Do not operate the 

heater for more than five (5) minutes with the access door panels removed.

• This heater is design certified by IAPMO as complying with the Standard for Gas Fired 

Pool Heaters, and is intended for use in heating fresh water swimming pools or spas.

• The heater is designed for the heating of chlorine, bromine or salt system swimming pools 

and spas. It should 

NOT

 be used as a space heating boiler, or general purpose water 

heater. The heater requires an external 

240 VAC single-phase

 electric power source.

• The heater should be located in an area where leakage of the heater or connections will 

not result in damage to the area adjacent to the heater or to the structure. When such 
locations cannot be avoided, it is recommended that a suitable drain pan, adequately 
drained, be installed under the heater. The pan must not restrict air flow.

• The heater may not be installed within 1.5 M (5 ft.) of the inside surface of a pool or spa 

unless it is separated by a solid fence, wall or other permanent barrier.
