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 shou Id be contacted for repair.
2. Do not block the exhaust pipe or the air inlet. This can cause incomplete combustion
and lead to gas poisoning.
3. During operation, check the flame through the sight glass for normal combustion.
Check for a compact, blue flame. Tall or excessively orange flames 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.
4. 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:
a) Turn off the gas supply valve, turn off the tap water supply valve, and turn the
water temperature 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 find 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 flammable agents to
clean the unit.
Regularly remove and wash the stainless steel filter in the cold water inlet.
During operation, take note of the flame and discontinue use if abnormal
combustion is detected.
Avoid accidents. DO NOT modify this unit in any way.
