9 This portion of this handbook applies to the Operations and Servicing of Residential Gas, T ank T ype, Water Heaters, which are vented atmospherically and use a thermocouple as their electrical source. Control: There are two gas control valve/thermostat con fi gurations available.
10 Burner/Manifold Door Assembly: The burner/manifold assembly consists of several components such as: main burner , burner ori fi ce, manifold tube, pilot burner , pilot ori fi ce, pilot tube, igniter , and thermocouple. See the fi gure below for the complete list of components.
11 Energy Cut Off (ECO): A metal tube (T emperature Probe) mounted onto the back of the gas control valve/thermostat is immersed inside the tank water .
12 Thermostat Operation: Standard residential water heaters use mechanical thermostats. With a mechanical thermostat, a dial setting of 120° F may shut the burner down at a tank temperature between 1 10° and 130° F . The heater will consistently shut off at this same temperature.

26 TECHNICAL BULLETINS W A TER HAMMER ..................................................................................................................................................27 MINERAL BUILD-UP ...............................................
27 BULLETIN 1 1 W A TER HAMMER GENERAL W ater hammer is the destructive force, pounding noise and vibration in a piping system when water fl owing through a pipeline is stopped abruptly . When water hammer occurs, a high intensity pressure wave travels back through the piping system until it reaches a point of some relief.
28 BULLETIN 13 MINERAL BUILD-UP SYMPTOMS • Rumbling • Crackling • Popping CAUSE With the increase in fuel costs and hot water consumption, deliming has become a necessity of modern maintenance. Lime (CaCO3), is the most notable factor when discussing water hardness.
29 BULLETIN 14 ALUMINUM HYDROXIDE SYMPTOMS “Crackling”, “gurgling”, or “popping” noises from new water heaters (installed less than six months).
30 BULLETIN 15 CONDENSA TION SYMPTOMS The water heater appears to be releasing water while the main burner is on or water is found surrounding the heater shortly after the water heater has been used. This bulletin explains why fl ue gases condense and how you can dif ferentiate between condensation and leaking.
31 BULLETIN 21 DISCOLORED W A TER SYMPTOMS Rusty , brown, black, or yellow water appearing in the hot water . CAUSES Complaints of discolored water are commonly blamed on water heaters and storage tan.
32 BULLETIN 22 SMELL Y W A TER CAUSES The most common cause of “smelly water” is a non-toxic sulfate reducing bacteria, scienti fi cally termed Divibrio Sulfurcans. This bacteria often enters the water system through construction or a break in ground piping.
33 BULLETIN 23 CHLORINA TION PROCEDURE CAUSES The chlorination procedure is used to eliminate various bacteria that accumulate and grow in water heaters. These bacteria often cause odorous or discolored water conditions. PROCEDURE Please read the steps of the chlorination procedure prior to beginning.
34 BULLETIN 35 NOT ENOUGH HOT WA TER - GAS CAUSES Complaints regarding an insuf fi cient supply of hot water are typically the result of a water heater that cannot meet the demands of the residence (both people and appliances).
35 BULLETIN 45 THERMAL EXP ANSION SYMPTOMS • Ef fects are only noticeable after hot water use followed by periods of no water use. • Relief valve drips during any recovery cycle when no hot or cold water is used. • Hot water pipes creak while heater is recovering and all valves are closed.
36 THERMAL EXP ANSION THE FIX The ideal fi x involves the use of a pressure reducing valve if supply pressures are above 60 to 70 psi, and a properly sized expansion tank. The PR V reduces supply pressures to 40 to 60 psi allowing an economically priced and sized expansion tank to be used.
37 BULLETIN 52 LEAKING TEMPERA TURE AND PRESSURE RELIEF V AL VE SYMPTOMS • W ater seeping around the relief valve tank connection • Leakage at the threaded portion of the relief valve connection .
38 BULLETIN 60 INSULA TION BLANKETS GENERAL The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Most modern water heaters have adequate factory installed insulation, the use of an after market insulation blanket is no longer recommended by most experts.
39 Draw efficiency is the quantity of hot water available to the consumer before the outlet water temperature decreases 25 degrees F . A 40 gallon water heater will typically provide 70% (28 gallons) of this “usable” hot water (60% is the minimum).
