A: Understanding How the Girard Tankless Water System Works
In a conventional installation the Girard Tankless Water Heater is connected to:

1. The RV’s cold water system deriving its water input from a pressurized (45 psi or greater) source such as a shore connection or an RV water pump connected to the RV’s fresh water storage NOTE – A steady water low (no pulsating) will ensure a consistent temperature and performance.
2. The RV’s hot water system (i.e. faucets and shower).
3. The RV’s LP Gas system capable of supplying its rated BTU requirement. The Girard Products model GSWH-2 introduces a new generation of smart tankless water heater designed specifically for Recreation Vehicles (RV). Its configuration and size are consistent with the tank based RV water heaters currently in use and is designed for OEM’s and after- market use by the RV industry.

The RV’s 12VDC electrical
The Water Heater’s microprocessor based controller (Control Module) receives from electronic sensors the data it needs to decide each step of the Model GSWH-2 operation.

1. Display on the User Control Panel (UCP) each phase of the Water Heater’s operation and receive from the user the operation parameters desired:
   • ON/OFF to activate
   • Desired outlet temperature
2. Verify that all components are in working order and that it is safe to start the unit upon sensing the minimum amount of water low required (.90 Ga/min)
3. Verify that the blower is operating and supplies the air low needed to maintain clean combustion.
4. Open the gas control and light the burner according to the procedure required by the safety standard
5. Adjust the gas low to reach and maintain the desire temperature set by the user
6. Continue operation as long as:
   • The water low is above the minimum required
   • The presence of lame is verified
   • No unsafe condition develops
7. Provide the user with a visual indication of the operating conditions turning on the appropriate icon and displaying the current outlet temperature:
   • Fan icon on: Blower operating
   • Flame icon on: Burner is lit and lamed is detected
   • Shower Head on: Water is lowing
8. The button marked “C/F” determines if the temperature is displayed in °F or °C degrees
9. Whenever the “UP” or “Down” are pressed the display shows the set temperature
10. If an unsafe condition is encountered and the unit shuts off, the display will show an Error Code corresponding to the actual condition that caused the unsafe condition.

See Troubleshooting section for a list of all error codes

B. Water Control Valve Flow Optimization (optional)

• The Water Control Valve of the GSWH-2 provides good control of the outlet temperature within a wide range of inlet water temperatures as are normally encountered in Recreational Vehicles. The unit is shipped with the Water Control Valve set at fully open/maximum low. If desired, the operating low can be manually adjusted. It is located on the rear of the water heater.
• In case of operation with extreme cold inlet water temperatures (approximately less than 45°(F) the performance of the Water Control Valve can be optimized by adjusting the low as shown in Figure 8 below.
• NOTE – This also can be accomplished by adjusting the hot water low at the faucet.

C: Operating Procedures
The Model GSWH-2 can be operated from the User Control Panel (Figure 9) which includes the Power ON/OFF switch

The model GSWH-2 can be operated in two different ways:

1. Operate like a Tank Water Heater. The user turns on the hot water and add cold water to achieve the desired Hot water temperature.
2. Select the desired temperature by adjusting temperature setting up (^) or down (v). The UCP settings are from 95° (F) to 124° (F). The unit will maintain the set temperature.
   Note – The recommended and Factory setting is 115° (F) or 46° (C).

For normal operation:

1. Turn on the The panel will light and will display the current temperature at the inlet of the unit.
2. Press a temperature selection arrow (up or down) to see the current set temperature
3. Adjust the set temperature to your preference
4. Turn on the

WARNING!
It is dangerous to operate a Tankless Water Heater unattended. This may occur accidentally if a sufficient leak develops in the water system or if a faucet is left open. For this reason The GSWH-2 will automatically turn off after operating for 20 minutes and displays Error “En” on the Display

D: Winter Use

Winterization
Freezing of the water heater and its plumbing components will result in severe damage not covered by warranty. For this reason it is advisable to follow the recommendations below if the unit is to be stored in a freezing environment or for long periods of time. At the start of the winter season or before traveling to a location where freezing conditions are likely, the unit must be winterized. The very small amount of water present in the heat exchanger DOES NOT require the installation of a bypass kit. Winterization can be accomplished using one of the two common methods of winterization used for RV water systems:

• Compressed Air method: Drain all water from the system opening one tap at a time and using compressed air to purge all remaining water.
• Anti-freeze method: Follow the recommendations of the Recreational Vehicle manufacturer and ill the system with a non-toxic anti-freeze. Make sure that the anti-freeze lows from each tap to complete the process.

Antifreeze Device
If you wish to operate the water heater in potentially freezing conditions the model GSWH-2 has a built in thermostat that will start the burner whenever the temperature of the Heat Exchanger falls below 38ºF and will automatically shut off when it senses a temperature in excess of 58 º F

IMPORTANT NOTICE
To allow the Antifreeze Device to operate you must have suficient LP Gas in the tank and 12VDC power available and you must leave the unit powered with the ON / OFF switch in the ON position at all times that freezing may occur. It will not protect the entire RV’s plumbing system. The RV must be designed for winter use/freezing conditions

E: Replacement Parts: Components

Troubleshooting

If a failure were to occur in the GSWH-2 it will be detected by the Controller Module and the specific cause will be indicated by the Error Code on the User Control Panel display.

• E0: Water Outlet Temperature Probe failure.
  An open circuit or short circuit condition is detected: This could be due to an internal failure in the Temperature Probe or to a faulty connection (Wires)

• E1: Ignition failure or accidental lame off during ignition.
  If the established lame signal is lost while the burner is operating, the control will respond within 0.8 seconds, the gas valve is de-energized and a new inter-purge and ignition routine will begin. If the burner does not light, the control will de-energize the gas valve and will make one more attempt to relight the burner. If the burner does not relight after the two trials the control will go into LOCKOUT and the unit will need to be turned off before it can operate again. (Turn hot water faucet OFF and back ON to re-set) This could occur for a number of reasons

• The most common are:

  • Lack of Gas in the tank
  • Faulty Igniter
  • Faulty Igniter connections
  • Improper distance between the Igniter and the Burner
  • Accumulated dirt or obstruction between
  • Igniter and Burner
  • Low Gas Inlet pressure

• E2: Flame sensing interrupted during normal operation. Buzzer will sound.
  Possible causes are the same as indicated by Error E1 if any of these conditions occur during normal operation. A lock out will occur also in these conditions.

• E3: ECO open before ignition or during normal operation.
  This occurs if the ECO thermostat opens. Under normal circumstances this is due to the Temperature of the water at the Outlet exceeds 140˚ F (60°C). The cause must be identiied and removed before restarting the unit.

• E4: Water Inlet Temperature Probe probe failure.
  An open circuit or short circuit condition is detected: This could be due to an internal failure in the Temperature Probe or to a faulty connection (Wires)

• E5: Blower motor failure.
  No motor signal was detected before ignition or during normal operation. This could be also caused by a wiring fault in the motor connections.

• E6: Over Temperature.
  Outlet Water Temperature has exceeded 140°F (60°C) for 3 sec.

• E7: Linear valve failure:
  The Controller Module detects an open circuit in the Linear Valve control circuit before ignition or during normal operation indicating a faulty Valve.

• E8: Air pressure switch:
  Air pressure switch not detected for 7 sec. before ignition or is cut-off for 2 sec. during normal operation. This failure may be caused by a faulty motor or a blockage in the air supply or in the exhaust system.

• E9: Flame sensor:
  Flame is sensed before ignition. Buzzer will sound. This is displayed when a short is detected in the lame sensor.

• En: System Timer:
  Water Heater ran longer than 20 min.

• Fd: Water heater operating in Winter Use Mode (Freeze Protection):
  The unit will run for a few seconds and shut off. This will occur when in freezing conditions if the LP gas and 12V power are ON. This Mode will only protect the water heater Heat Exchanger and not the RV’s plumbing system.
