3 are different from natural gas models. A natural gas heater will not function safely on LP gas and no attempt should be made to convert a heater from natural gas to LP gas. GPG/GPV-540A, 650A & 740A models are not available for use with Liquefied Petroleum or LP gas. If you have obtained a GPG/GPV-540A, 650A or 740A model with the intent to u[...]

4 and sodium chloride (water softener salt), waxes, and process chemicals are typical compounds which are potentially corrosive. Do not store products of this sort near the heater . Also, air which is brought in contact with the heater should no contain any of these chemicals. If necessary , uncont aminated air should be obtained from remote or out[...]

5 Continued manual resetting of high limit control, preceded by higher than usual water temperature is evidence of high limit switch operation. The following are possible reasons for high limit switch operation. • A malfunction in the thermostatic controls would allow the gas valve to remain open causing water temperature to exceed the thermostat[...]

6 Units, which are to be installed on combustible flooring, must be supported by a full layer of hollow concrete blocks, from 8” (203.2 mm) to 12” (304.8 mm) thick and extending 12” (304.8 mm) minimum beyond the heater in all directions.
