L.P.G. (Bottled Propane) Models
Liquefied petroleum gas is over 50% heavier than air and in the occurrence of a leak in the system, the gas will settle at floor level. Basements, crawl spaces, skirted areas under mobile homes (even when ventilated), closets and areas below ground level will serve as pockets for the accumulation of gas. Before lighting an L.P. gas water heater, smell all around the appliance at floor level. If you smell gas, follow the instructions as given in the warning on the front page.
When your L.P. tank runs out of fuel, turn off the gas at all gas appliances including pilot lights. After the tank is refilled, all appliances must be
Water Heater Operation
Figure 11 below shows the water heater’s sequence of operation when a call for heat is initiated. The ignition control module will attempt to light the burner three times. If the ignition control does not detect ignition it will enter
WARNING
Water temperature over 125°F can cause severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of being scalded.
Feel water before bathing or showering.

temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores, see Figure 9. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat see Figure 13 and the table below. Using the lowest hot water temperature that meets your needs will also provide the most energy efficient operation of the water heater.
Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.

Burner Flames
Inspect the burner flames through the viewport and com- pare them to the drawings in Figure 16. A properly operat- ing burner should produce
a soft blue flame. Blue tips
with yellow inner cones are satisfactory. The tips of the flame may have a slight yellow tint. The flame
should not be all yellow or have a sharp
may cause an orange colored flame. Contact a qualified person if the flame is not satisfactory.
Water Temperature Regulation
Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30°F (16.7 °C) higher or lower at the point of use such as, bathtubs, showers, sink, etc.
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain

The thermostat of this water heater has been factory set at its lowest position, to reduce the risk of scald injury. It is adjustable and must be reset to the desired temperature setting.
The mark ( 
) (on temperature setting of gas control valve/ thermostat) indicative of approximately 120°F is preferred starting point. Some states have a requirement for a lower setting. If you need hotter water, follow directions for temperature adjustment, but beware of the warnings in this section.
Pressing the “COOLER” 
button decreases temperature and pressing the “HOTTER” 
button increases the temperature.
To avoid any unintentional changes in water temperature settings, the control has a tamper resistant feature
for changing the temperature setting. To change the temperature setting follow these instructions:
1.“Wake Up” the temperature indicators by holding down both “COOLER” and “HOTTER” temperature adjust- ment buttons at the same time for one second (See Figure 13). One or two of the temperature indicators will light up. These indicators will only remain on for
