2 FOREWORD The design of the GPG 540A through 740A models complies with ANSI Z21.10.3/CSA 4.3 as an automatic circulating tank and an automatic instantaneous type heater . The GPV 540A through 740A models are designed for sidewall venting and direct venting applications and are certified under UL 795.
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.
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.
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.
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.
7 Heater must be protected from freezing downdrafts during shutdown periods. 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.
8 Refer to T able 2 for limitations of venting system design for horizontal venting. T ABLE 2 GPV-540A-740A Flue Outlet Dia. (Inches/mm) 9” (228.6) Flue Reducer 9” x 8” Dimensions -Supplied (Inches/mm) 228.6 x 203.2 Minimum Outlet V ent Dia. (Inches/mm) 8” (203.
9 DIRECT VENTING - FOR GPV MODELS All exhaust vent terminal, flue reducer , and intake vent terminal are supplied with any unit intended for direct venting. These parts must be installed without alteration. This heater is category III appliance when used in a direct vent application.
10 1. Shall be located not less than 12” (304.8 mm) above grade. 2. Shall be located not less than 3 (.9144 m) feet horizontally from and not less than 3 feet (.9144 m) below an exhaust vent terminal. 3. Shall not be located directly above an exhaust terminal.
11 5. Attach a properly sized length of Selkirk Metalbestos model PS or model G venting to the exhaust vent adapter using the inner vee bands, see Figures 7 and 7B on page 10. 6. Fill the grooves in both inner vee bands with high-temp silicone sealant, Dow Corning 736 or equivalent.

18 MANIFOLD KITS Precision cut type “L” all copper State manifold kits assure water flow balance of all units. Without this balance, the full water heating and storage potential of the system cannot be achieved. Plus, the units with the higher water flow may have a shortened life.
19 HEA TER WIRING IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE APPLIANCE MUST BE REPLACED, IT MUST BE REPLACED WITH 105°C WIRE OR ITS EQUIV ALENT , EXCEPT IN THE BURNER HOUSING USE 200°C WIRE. The power burner is wired to the heater as shown in Figure 1 1 for GPG models and Figure 12 for GPV models.

22 FOR YOUR SAFETY READ BEFORE LIGHTING 1 . Remove thermostat control cover . 2 . Set thermostat to lowest setting. 3 . Turn burner switch to “OFF”. W ARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.
23 SEQUENCE OF OPERA TION – Power on. – Heater in standby mode. – Thermostat calls for heat. – Blower motor starts. – Blower operation closes the normally open blower prover/ blocked outlet safety pressure switch. – On proof of airflow , Honeywell S8680J flame control module energized.
24 1. Check gas line pressure with a manometer . Set initial gas line pressure at 9-10” w .c. before turning the heater “ON”. Read gas line pressure and gas manifold pressure when the heater main gas is “ON”. Adjust gas line regulator setting if the gas line pressure drops below 8” w .

27 GENERAL INFORMA TION POWER BURNER The initial start-up procedure of the gas power burner is provided on page 18 thru 21. Refer to Figure 12, burner exploded view for burner components location. The sequence of operation of the power burner is provided on page 15.
28 DRAINING The heater must be drained if it is to be shut down and exposed to freezing temperatures. Maintenance and service procedures may also require draining the heater . 1. Turn off the heater electrical disconnect switch. 2. Close the cold water inlet valve to heater .
29 ABOVE ALL, DO NOT PLUG THE TEMPERA TURE AND PRESSURE RELIEF V AL VE. THIS IS NOT A SOLUTION AND CAN CREA TE A HAZARDOUS SITUA TION. CIRCULA TING PUMP The water heating system may include a circulating pump. Where used, it should be lubricated as directed by the circulator manufacturer .
30 2. Check the fuses. • The electrical disconnect switch usually contains fuses. 3. The capacity of the heater may have been exceeded by a large demand for hot water . 4. Colder incoming water temperature will lengthen the time required to heat water to the desired temperature.
31 and the troubleshooting section of burner manual before continuing. Make sure the appliance is connected to a 120 V ac 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.
32 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. • Turn the burner switch to “OFF” position for at least one minute to reset the heater .
