GAS PRESSURE TESTING

Before operating the heater, the heater and its gas connections must be leak tested. Do NOT use an open flame to test
for leaks. Test all gas connections for leaks with soapy water or another non-flammable method.
The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The heater must be isolated from the gas supply
system by closing its individual manual shut-off valve during any pressure testing of the gas supply at test pressures
equal to or less than 1/2 psig (3.5 kPa).
Caution: Dissipate test pressure in the gas supply line before reconnecting the heater and its manual
shut off valve to gas supply line. Failure to follow this procedure may damage the gas valve. Over pressur-
ized gas valves are not covered by warranty. The heater and its gas connections shall be leak tested before
placing the appliance in operation. Use soapy water for leak test. Do not use open flame.
Note: do not use threaded seal tape on gas line pipe thread. A pipe compound rated for use with natural
and propane gases is recommended. Apply sparingly only on male pipe ends, leaving the two end threads
bare.
Special safety and precautions for LP gas: If proper ventilation is not provided gas can collect or pool
in enclosed areas, because LP gas is heavier than air. Pentair does not recommend installing the heater in
an enclosed areas, such as a ground pit. If the heater is required to be installed in an enclosed area, be sure
proper ventilation for LP gas are met and locate the heater a safe distance from LP gas cylinders and filling
equipment. Before installation, consult the national fuel gas code (NFPA 54 / ANSI Z223.1, Latest
edition), the natural gas and propane installation code in Canada (CAN/CSA B149.1, Latest edition),
and any other local codes and fire protection authorities about specific installation restrictions in your
location.

CHECKING GAS PRESSURE THROUGH GAS CONTROL VALVE

Risk of explosion if a unit burning 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 and specific installation restrictions of the heater relative to propane storage tanks and
filling equipment. Installation must meet the requirements for the Standard for the Storage and Handling of Liquefied Petroleum
Gases, CAN/CSA B149.2 (latest edition) or ANSI/NFPA 58 (latest edition). Consult local codes and fire protection authorities
about specific installation restrictions.
CHECKING THE GAS PRESSURE THROUGH THE COMBINATION GAS CONTROL VALVE (See Figure
15): Before operating the heater, the heater and its gas connections must be leak tested. Do NOT use an open flame
to test for leaks. Test all gas connections for leaks with soapy water or another non-flammable method.
The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The heater must be isolated from the gas supply
system by closing its individual manual shut-off valve during any pressure testing of the gas supply at test pressures
equal to or less than 1/2 psig (3.5 kPa).
