Use and Care Manual

1. If a gas leak is detected at any time, close the main gas valve immediately. The Marey
service center or your local gas company should be contacted for repair.
2. Before going to sleep or leaving the house, the gas supply should be shut off.
3. Do not block the exhaust pipe or the air inlet. This can cause incomplete combustion and
lead to gas poisoning.
4. During operation, check the re through the sight glass for normal combustion. Check for a
compact, blue ame. Tall or excessively orange ames indicate abnormal combustion. If there
is abnormal combustion, close the gas valve immediately and contact the Marey service center
or your gas company for maintenance.
5. When outdoor temperatures are below 32 degrees F and pipe freezing may occur, any water
remaining in the unit after use should be discharged to avoid freezing. Water should be
discharged in the following manner:
Turn off the gas supply valve, turn off the tap water supply valve, and turn the water tempera-
ture adjusting switch to the low temperature position. Turn on the hot water supply valve and
remove the water discharge valve to discharge the water remaining in the unit. Reinstall the
water discharge valve.
Check the gas pipes, hoses, and vent pipes regularly. If you nd joints that are not tightly
secured or if there are cracks or corrosion anywhere, you should stop using the heater and
perform the necessary maintenance immediately.
Check regularly for water or gas leaks and correct immediately.
Regularly clean the surface of the water heater to remove dirt or dust with a wet cloth, and
then use a dry cloth to remove moisture. For hard to remove dirt, please use a mild spray
cleaner or detergent.
Do NOT use strong detergents, benzene, gasoline, or other ammable agents to clean the unit.
Regularly remove and wash the stainless steel lter in the cold water inlet.
During operation, take note of the ame and discontinue use if abnormal combustion is
detected.
Avoid accidents. DO NOT modify this unit in any way.
