OPERATING YOUR WATER HEATER

Read and understand these directions thoroughly before attempting to operate the water heater (see Lighting Instructions on page 20). Check the data plate on the front of the water heater for the correct gas. Do not use this water heater with any gas other than the one listed on the data plate. If you have any questions or doubts, consult your gas supplier or gas utility com- pany.

L.P. (Propane) Models

Propane gas is heavier than air and in the occurrence of a leak in the system, the gas will settle on the 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 a propane 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 propane 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 re-lit according to their manufacturer’s instructions.

Water Heater Operation

When the thermostat calls for heat, it will signal the damper to open. Once the damper fully opens, it will signal the igniter to light the pilot. The pilot will then ignite the main burners. The water heater will operate until the call for heat ends. At this time the main burners and pilot will shut-off and the damper will close. See Figure 12 below for a sequence of operation flowchart.
