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, uncontaminated air should be obtained from remote or outside sources. The limited warranty is voided when failure of water heater is due to a corrosive atmosphere.
LOCATING THE HEATER 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. When installing the heater, consideration must be given to proper location. Location selected should be as close to the stack chimney as practicable, with adequate air supply and as centralized with the piping system as possible.
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. The concrete blocks must provide an unbroken concrete surface under the heater with the hollows running continuously and horizontally. A 3/16-inch steel plate must cover the concrete blocks, see Figure 2.
Heater must be protected from freezing downdrafts during shutdown periods. NOTE: A NEGATIVE DRAFT MUST BE MAINTAINED IN VENTING. The GPG 540A, 650A and 750A water heater are classified as a category I appliance (non-positive vent pressure, non-condensing) when installed with the supplied barometric draft control assembly in a vertical vent installation. A negative draft of 0.02” to 0.04” w.c. Must be maintained in venting system. Measure draft at the location illustrated in Figure 4.

2. Check the fuses. • • Excessive water pressure • Excessive water temperature The electrical disconnect switch usually contains fuses. • Faulty relief valve 3. The capacity of the heater may have been exceeded by a large demand for hot water. Excessive water pressure is the most common cause of relief valve leakage. It is often caused by a “closed system”.
20, and the troubleshooting section of burner manual before continuing. • Make sure the appliance is connected to a 120 Vac power supply, burner switch is “ON” and manual gas valve is in the “ON” position, and all electrical connections are secure before continuing to troubleshoot this appliance. Check for the continuity between the flame rod and sensor connection at Honeywell flame control module by the ohm meter.
2. Check for 24V at the Robertshaw gas valve when the main gas light is on. If there’s no 24V at the valve, check loose wire connection. 5. As soon as the pilot gas valve is energized, check for the burner pilot flame through the burner peek-hole. If the pilot flame is established inside the burner, then proceed to Step 6. 3. Check for gas supply line pressure. The gas line pressure before the valve should be maintained at minimum 8” w.c. when main flame is “ON”. If the gas line pressure drops below 8” w.
