Water Temperature Regulation

The thermostat is adjusted to its lowest temperature position when shipped from the factory. The temperature of the water can be selected by setting of the temperature dial on the front of the gas control. The “LOW” position on the thermostat is the preferred starting point for setting the temperature/control knob (approximately 120OF(50OC)). Energy conservation is a consideration when selecting the water temperature setting.

HIGHER SETTING INCREASES THE RISK OF SCALD INJURY

In households with children, the elderly or handicapped persons, select a lower temperature setting. To reduce the risk of scalding, valves for reducing the point of discharge water temperature by mixing the branch water lines are available. Please consult a licensed plumbing authority.

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 1/8” N.P.T. port is provided on the gas valve control for connection to a gauge to measure the pressure. 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/3600

*Gas Heating Value in BTU/cubic feet or cubic meters 1 cubic meter = 35.31 cubic feet

3.Checking burner flame - 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 is on the rating plate and the label on the side of the gas valve control. Poor flames can also be caused by incorrect gas pressures or burner orifice size, inadequate or contaminated air, a restriction in the venting system, or dirt entering the gas supply. These conditions must be corrected to prevent a possible safety hazard.

•For units with cast iron burners, the flame presentation should be the same as sheet metal burners. Adjustment is possible on cast iron burners by changing the air shutter position on the burner inlet. If the flame needs adjusting, loosen the two screws and move the shutter. See Figure 8. If it is too far open, the flame will lift off the burner or will be noisy; if it is closed too far, the flame will be luminous and yellow. Once proper flame is obtained, tighten the screws to secure the air shutter.

NOTE: There is no means for flame adjustment on sheet metal burners as they are self-adjusting.

IMPORTANT: Always return the burner doors to their original position.

ALWAYS KEEP THE AREA AROUND THE WATER HEATER CLEAR OF COMBUSTIBLE MATERIALS. NEVER RESTRICT THE FLOW OF AIR TO THE WATER HEATER.

VII) SERVICE AND MAINTENANCE

This section describes the routine service instructions to properly maintain your heater and venting system.

Not Enough or No Hot Water

•Check that the water heater is operational.

•Relight the pilot burner if necessary.

•Check that the thermostat is set high enough.

•Check that you have not just run out of hot water due to heavy demand. If this is a routine problem, it may indicate an under- sized water heater.

•Have your gas company check input rate and water heater operation.

•The E.C.O. may have tripped open. See E.C.O. below.

Energy Cut-off Control (E.C.O.)

This water heater is equipped with a control which has a built in E.C.O. (Energy Cut-Off). The E.C.O. will shut the gas off, should the outlet water temperature exceed maximum temperatures. If the E.C.O. has tripped, the entire gas valve/temperature control must be replaced. For gas valve/temperature control replacement, contact your local gas utility, or a qualified service technician. The replacement control must be an approved equivalent model to the control which has been removed.

Water Temperature is Too Hot

•Check that thermostat setting is not too high.

•Water heaters used for dishwashers, space heating or laundry facilities generally require higher temperatures than domestic use. Install anti-scald tempering valves as instructed in the safety warnings.

•If the problem persists, contact your dealer or gas supplier.

Hot Water Odour

On occasion, and depending on your location, hot water may develop a strong odour. This can be especially problematic in regions where the water contains some sulphur, which results in hot water having a “rotten egg” smell.

If this occurs, drain the system completely, flush thoroughly and refill. If the problem persists, the anode rod may need to be changed from magnesium to one made of aluminum. In certain cases chlorination and flushing of the water heater may be required. Contact you dealer or water supplier.
