WARNINGS AND SAFETY INFORMATION
(CONTINUED)
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 G20, G25 or G31 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 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 (latest edition).
WARNING
—
Risk of fire.
Do not place articles on, near or against the heater.
WARNING —
Risk of burn hazard.
To reduce the risk of injury, do not touch the side heater vent cover when the
heater is operating. Side heater vent covers are HOT and can burn when touched causing personal
injury. Do not allow children to play on or around heater or associated equipment.
The average
temperature of the heaters flue exhaust is 204 degrees Celsius (°C).
WARNING —
Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly
when installing heater.
Do not use a draft hood with this heater, as the exhaust is under pressure
from the burner blower and a draft hood will allow exhaust fumes to blow into the room housing the
heater. The heater is supplied with an integral venting system for outdoor installation.
CAUTION —
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper
and dangerous operation. Wiring errors can also destroy the control board.
• Connect heater to
240
Volt, 50 Hz., Single Phase power only.
• Verify proper operation after servicing.
• Do not allow children to play on or around heater or associated equipment.
• Never allow children to use the pool or spa without adult supervision.
• Read and follow other safety information contained in this manual prior to operating this pool
heater.
