“AIR” IN HOT WATER FAUCETS
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the pos- sibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is pre- sent, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.
VENTING MANUAL RESET SWITCH
There is a venting manual reset switch located on the vent- ing hood. If the switch is activated, it will not reset itself. Before resetting this reset switch, check for flue blockage and propriety of the venting system. To reset, press the red button.

WARNING
Should overheating occur or the gas supply fail to shut off, turn “off” the manual gas control valve to the appliance.
NOT ENOUGH OR NO HOT WATER
1.Check the manual gas shut off valve to be sure it is open.
2.The ON/OFF switch on the control box must be “ON”.
3.The temperature button adjustment may be set too low. See the “Temperature Regulation” section.
4.The gas company can check the gas input to see if it is correct. An underfired water heater will not heat water as quickly.
5.Look for leaking or open hot water faucet’s. Make sure all are closed.
6.The cold water inlet temperature may be colder during the winter months. It will take longer to heat the water and seem like less hot water.
7.If you cannot find what is wrong, call the local gas util- ity and/or plumbing contractor.
WATER IS TOO HOT
1.The temperature adjustment setting may be set too high. See the “Temperature Regulation” section.
NOTE: A period of time is necessary after an adjust- ment has been made for the water temperature to reach the new temperature setting.
2.If lower temperature settings will not lower the water temperature, call the local gas utility.
