Converting your propane (LP) water heater to natural gas (NAT):
To convert your water heater from propane (LP) to natural gas (NAT) follow the above steps except:
4. Remove the brass screw. Rotate the screw 180˚ and insert screw back into gas regulator (The arrow on the
brass screw indicating “NAT” should be pointing to the gas control).
15. Remove the propane main burner orifice from the manifold tube.
16. Install the natural gas main burner orifice into the manifold tube (Supplied in the bag attached to the drain
valve).
18. Replace the pilot assembly set for propane with the one supplied in the bag attached to the drain valve set
for natural gas.
24. If necessary, remove the high limit switch (set for propane) on the right portion of the inner access door and
replace it by the high limit switch supplied in the bag attached to the drain valve (set for natural gas).
Refer to Table 1.
Leak Test the Gas Connections before Placing the Water Heater in Operation
Light the water heater as outlined in the owner’s manual. Using a soap and water solution or leak test solution, test
all of the gas connections to the gas control by spraying the solution on them. The appearance of bubbles means that
there is a leak. If this occurs, tighten the connection and re-test.
