Incoming water supply. 3. Adjust high demand usage. 4. water heater’s rated manifold pressure (check rating plate). shutter nut. Too much air will cause the flame to lift off the burner ports and create noisy burner operation.
Inspect other appliances near water heater. STAY LIT Flame arrestor openings blocked. Contact a service agency to determine cause. Defective Gas Control. Replace Gas Control. Dirty pilot burner. WATER TOO HOT Thermostat set too high.
If a water heater is modified for high altitude, then either the heater must be derated or the fuel must be Abnormal flame patterns (not clean, blue and steady) All of these symptoms may indicate too much fuel present – and not enough oxygen for complete combustion. Exceptions:
• Flame Failure: The appliance will automatically There is hot water scald potential if the thermostat is set too high. Water temperatures over 125º F Water Heater High Altitude Installation Setting Procedure 32 Manual
After successfully lighting the water heater, allow the hot water scald potential if the thermostat is set too high. IMPORTANT: Incorrect flame lazy yellow Water temperature over 125°F can cause severe burns instantly or death from
As the water heater in most new homes has been banished to the garage, basement, Gas burning appliances must have air (Oxygen) to sustain a flame, and water heaters in garages and attic or utility closets have plenty of air around them; right? a vent that is too big for the heater.
If the water temperature is set too high. Households with small children, the disabled, or elderly persons may require a 120°F flame of the water heater’s main burner can ignite these vapors causing an explosion or fire. NOTICE:
CLEANING THE FLAME ARRESTOR: 1. Turn the water heater gas control knob to Do not bend the gas control valve/thermostat connections too far; doing so may result in damage. Robertshaw base (disrupting air ﬂ ow), install 1/2-inch high feet under the radiation shield. To obtain the feet
Burner flame too high 1. Improper gas pressure 2. Wrong orifice Check and adjust Install correct orifice Water too hot (followed by pilot Water heater is leaking (Gas water heaters produce condensation 1. Cold in or hot out joints 2. T&P valve
O. Water or antifreeze may be in the tank, or the flash point could be too high. (Such as brand then a loss of flame. Check this 300-watt heater element (with an inductive amp meter); it should pull 2 3/4amps when the flame first fires. But,
Attempt to light this heater manually with a match or flame-producing device. Follow the Lighting Instructions (Robertshaw) given on the side of the water heater and also depicted in this manual. See also “Gas Supply”, “Water too high. In households with children, disabled or the
Too small a pilot flame, rust inside combustion chamber can mean vent condensate dripping down water heater and extinguishing flame. EXCESS OF 180° F WILL CAUSE HIGH LIMIT CONTROL (ECO) TO OPEN AND SHUT OFF GAS SUPPLY TO UNIT.
Impedance at overtemperature sensor < 400 ohms. Ventilate heater (water level too low). has started (flame detected) and indicates flame loss in a power setting. Check fuel flow rate, blower speed, 054 Flame loss in „High” setting fuel supply, exhaust pipe and combustion air piping. If
Ludell Water heater Lockouts This will simulate that the water level in the shell is too high and will electrically shut Flame Fail – Cracked/broken spark rod-no-spark (Check spark rod adjustment) – Gas valve(s) off-gas supply
The DSI water heater must have an acceptable DC-voltage range to function properly. An adequate voltage Pilot flame adjustment too high. Flame spreader misaligned – square with end of burner. b) Not enough hot water: 1) Thermostat set too low.
