Gas Pressure Testing; Checking Gas Pressure Through Gas Control Valve - Pentair ETi 250 Installation And User Manual

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 pressurized 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 Propane gas: If proper ventilation is not provided gas can collect or pool in enclosed
areas, because Propane 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 Propane
gas are met and locate the heater a safe distance from Propane 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 19): 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).
