Important Safety Information To prevent damage to property and injury to the user, the icons shown below will be used to warn of varying levels of danger. Every indication is critical to the safe operation of the Water Heater and must be understood and observed. Potential dangers from accidents during installation and use are divided into the following four categories. Closely observe these warnings; they are critical to your safety. Icons warning of risk level This is the safety alert symbol.
WARNING A. This Water Heater does not have a pilot. It is equipped with an ignition device that automatically lights the burner. Do not try to light the burner by hand. B. BEFORE OPERATING smell all around the Water Heater area for evidence of leaking gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building.
WARNING Be sure the gas/power supplied matches “Type of Gas” and “Electrical Rating” on the rating plate. (e.g. NCC199CDV (GQ-C3260WZ-FF US)) [When supplying combustion air from the indoors] Check the air supply opening for dust or obstructions. To prevent injury or death, do not allow small children to bathe or play in the bathroom unsupervised. Do not touch the power cord with wet hands. Contact a qualified service technician for any necessary repairs, service or maintenance.
NOTICE Do not disassemble the Remote Controller. Do not drink water that has been inside the appliance for an extended period of time. Do not drink the first use of hot water from the appliance in the morning. Do not use chlorine-based, acidic, alkaline detergents, organic solvents such as benzine and thinner, or Melamin Sponge to clean the Remote Controller. This may cause discoloration, deformation, scratches or cracks.

Preventing Damage from Freezing NOTICE • Damage can occur from frozen water within the appliance and pipes even in warm environments. Be sure to read below for appropriate measures. • Repairs for damage caused by freezing are not covered by the warranty. Freezing is prevented within the device automatically by the freeze prevention heater. Freezing cannot be prevented when the power plug is unplugged. Do not remove the power plug from the wall outlet.
If the Water Heater will not be used for a long period of time, drain the water. Manual Draining 1. Close the gas valve. WARNING • To prevent burns or scalding, turn off the Power button and wait until the appliance cools before draining the water • Do not touch the power cord with wet hands. • To prevent damage from freezing, the Water Heater must be plugged into power at all times. If power is unplugged, drain the water completely from the Water Heater.
Turning the Water Heater Back On DANGER After the Water Heater has been out of use for a long time, make sure that you fill the condensate trap with water. This is to prevent dangerous exhaust gases from entering the building. Failure to fill the condensate trap could result in severe personal injury or death. (By performing step 4 as described below, the condensate trap will automatically fill itself with water.) WARNING Do not touch the power cord with wet hands. 1.
Regular Maintenance Periodic Inspection Periodic check and maintenance should be performed once a year by a qualified service technician to assure that all the equipment is operating safely and efficiently. We recommend to make necessary arrangements with a service contractor. WARNING To prevent burns or scalding, turn off the Power button and wait until the appliance cools before performing maintenance. A Check : C • For abnormal sounds during operation.
Water Drain Valve (with Water Filter) If the water drain valve (with water filter) is covered with debris, the hot water may not run smoothly, or the Water Heater may put out cold water. Check and clean the filter as explained below. WARNING To prevent burns or scalding, turn off the Power button and wait until the appliance cools before draining the water. 1. Close the hot water valve and the water supply valve. O-Ring Hot water valve Water supply valve Water drain valve with water filter 2.
Troubleshooting Initial Operation Temperature The Water Heater does not attempt to ignite when water is running. • Check for reversed plumbing or crossed pipes. • Check the water filter. (See page 29) Hot water is not available when a fixture is opened.
Fluctuations in hot water temperatures. • Set water temperature at 115°F to 120°F or 48°C (118°F) to 50°C (122°F). This will allow you to use a higher flow of hot water thus meeting the minimum flow requirement of 0.29 GPM (1.1 L/ min)*. *Minimum activation flow rate: 0.5 GPM (2.0 L/min) Minimum operating flow rate: 0.29 GPM (1.1 L/min) • Clean the water filter of any debris (See page 29) Setting temperature cannot rise.
Checking for Error Conditions When a failure occurs, information relating to the error blinks on the display. The error alarm may also continuously sound. If this occurs, take appropriate measures as following list. [Error Code Display Screen] Error Code : 90 Cause : [ When supplying combustion air from the indoors] The air supply vent may be clogged. Action : Check air supply vent for blockage or obstruction.
