39 SECTION VII: OPERATING INSTRUCTIONS WARNING Water heaters are he at-producing app liances. To avoid damage or injury there must be no materials stored against th e water heater or direct vent sy stem, and proper care must be taken to avoid unnecessary contact (especially by children ) with the water heater a nd direct vent system.
40 LIGHTING INSTRUCTIONS FOR YOUR SAFETY READ BEFO RE OPERATING WARNING: If you do not follo w these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This water heater does not have a pilot.
41 CAUTION In climates wh ere below free zing temper atures may occ ur, the water heater must b e drained when power is off to the water heater to prev ent free ze damage to the heat exchanger. Drain sol enoids are recommended to prevent freeze damage during p ower failures in cold climate regions.
42 2. To set the de sired temperature on the control, all hot water faucets must be closed. If there are more remote control s installed, press t he “Priority” button on the control you want to change the setting on and the “Priority” indicator light will glow.
43 SCALDING Figure 17. Scalding Warning. This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot w ater to avoid scalding injury. Cer tain applianc es, such as dishwas hers and automatic clothes washers may require increased wate r temperature.
44 DIAGNOSTIC CODES ON THE TEMP ERATURE CONTROL DISPLAY The Bradford White EverHot tankless water heate rs have the ability to monitor and display any operating faults on the control display. The diagnostic codes will display on the monitor and will assist in servicing the water heater.
45 Code Code Description Remedy 16 Over Temperature Warning Check for restrictions in air flow around unit and vent terminal. Check for low water flow in a circulating system causing sh ort-cycling. Check for foreign materials in combustion ch amber and/or exhaust piping.
46 SECTION VIII: MAINTENANCE WARNING Always turn off the electrical power supply, the manual ga s valve, and the manual water control valve whenever servicing this applian c e. KEEP THE WATER HEATER AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.
47 CAUTION Before manually operating the valve, make su re t hat a drain line has been attached to the valve to direct the discharge to a n open drain. Failure to take this precaution could mean contact with extremely hot water passing out the valve during this checking operation.
