GSW POWER VENTED GAS FIRED WATER HEATER Initial Start Up, Performance Checks

Initial Start Up

TURNING WATER HEATER OFF

1.With all gas valves closed and the power cord NOT plugged into an electrical outlet, make sure that the water heater is filled with water and that the cold water supply valve is open.

2.Open the manual shut off valve in the gas supply line and turn the water heater’s gas control switch to the “ON” position. Wait for five minutes. Smell around the water heater for any possible gas leak, Check close to the floor and around the burner door area as some gases, especially propane, are heavier than air.

IF YOU SMELL GAS:

ØDo not try to operate the water heater or any other appliance.

ØDo not operate any electrical switch; do not use a telephone.

ØImmediately call your gas supplier from a neighbor’s telephone. Follow the gas supplier’s instructions.

ØIf you cannot contact your gas supplier, call the fire department.

3.To start the water heater, set the thermostat to the mid point arrow on the dial (approximately 120°F, 50°C) and plug in the power cord. The system will start automatically.

4.The gas valve will first do an initial diagnostic to check that it is working properly. Once proven, the control will energize the blower assembly and power through the pressure and high temperature safety switches.

5.With pressure and temperature safety switches proven, power is sent to the ignition system. The ignitor will glow until it reaches optimum temperature. Full glow takes approximately 15 seconds.

6.With ignitor proven, the control will open the internal gas valve, allowing gas to flow to the burner. Main flame is established and envelops the flame sensor rod. This rod monitors flame stability. If the flame fails the system will shut down.

7.The heater will continue to operate until the water temperature reaches the thermostat setting. At that time the burner will shut down, while the blower continues to operate for a brief post-purge sequence.

8.The water heater will remain off until the water temperature drops sufficiently to reactivate the system or the thermostat is set to a higher requirement.

1.Turn thermostat to its lowest setting.

2.Turn control switch to the “OFF” position.

3.Turn gas supply valve “OFF”.

4.If the blower is still running, wait for it to stop.

5.Unplug electrical cord.

Performance Checks

1.Burner Manifold Pressure - The burner operates at a manifold gas pressure of 3.5" W.C. for natural gas and 10.0" W.C. for propane gas. A _” N.P.T. port is provided on the gas valve control for connection to a gauge to measure the pressure (See Figure 11). The control valve has an internal pressure regulator. Do not confuse the manifold pressure with the supply inlet pressure. Return port plug upon completion of tests.

2.Checking Input - Never exceed input shown on the rating plate. Ask your gas supplier for the heating value of the gas you are using. Check the input by ”clocking” the gas meter. Make sure no other appliances are operating when the test is being done. To ensure accuracy, clock enough gas so that the time is greater than 60 seconds. Use the following formula to check input. Check that your gas pressures are as previously stated.

Input

Gas Heating Value* x Cubic Feet/Meters clocked

(BTU/Hour) =

Seconds clocked

*Gas Heating Value in BTU/cubic feet or cubic meters

1 cubic meter = 35.31 cubic feet

3.Checking burner flame - Superflue Water Heaters may use either a sheet metal or cast iron burner. Access the burner by lifting off the outer gas door and sliding open the inner door located at the bottom of the water heater.

∙for water heaters having a sheet metal burner and burning natural gas, a constant, steady, soft blue flame should be visible coming from the burner head

∙for water heaters having a sheet metal burner and burning propane gas, the flame will be a constant, steady blue with a brighter blue being visible right at the burner head. The very ends of the flame may be tipped with yellow. This is more noticeable on higher input units.

∙Noisy, hard blue flames, flames lifting from the burner, luminous or yellow stringy flames indicate an incorrect setup. Check that the unit is using the correct gas. This information
