IMPORTANT WARNING AND SAFETY INSTRUCTIONS
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.
Risk of explosion if a unit converted to propane gas is installed in a
pit or other low spot. Propane is heavier than air. Do not install the heater
using propane in pits or other locations where gas might collect.
Consult your local building code officials to determine installation
requirements of heater relative to propane storage tanks and filling
equipment. In Canada, Installation must meet the requirements of the
Standard for the Storage and Handling of Liquid Petroleum Gases,
CAN/CSA B149.1 (latest edition). In the U.S. installation must meet the
requirements of the Standard for the Storage and Handling of Liquefied
Petroleum Gases, ANSI/NFPA 58 (latest edition). Consult local codes and
fire protection authorities about specific installation restrictions.
Propane (LPG) fired heaters must not be installed in garages in
Massachusetts, by order of the Massachusetts State Fire Marshall. For
more information, call the Fire Marshall's office.
