The accessories should include installation guide, owner’s manual, and a fittings bag.

Exhaust Vent Pipe Predetermined

The exhaust vent pipe must extend outdoors. The vent should be outward and downward at minimum 3? to prevent rain and condensed water from getting into the vent pipe, and damaging the tankless water heater.

Position By Paper Drilling Template

Carefully measure the space and calculate where to install the water heater per the exhaust pipe position. Use the paper drilling template from the accessories to position and adjust. Pay attention to the minimurn distance from combustible or non-combustible  objects.

Drill And Fix Screws

Drill holes in the wall using an impact drill. Put the plastic ribbed anchors into the holes first, and then the screws, and tight them up.

Mount to Wall

Hang the water heater onto the anchor screws, and tight the machine up with other screws coming altogether.

Connect Valves, Water And Gas Pipes

Install a cold water isolation valve to the water inlet, and a hot water isolation valve plus a pressure relieve valve to the hot water outlet. Make sure connect cold and hot water pipes respectively to the cold water inlet and hot water outlet.

Check For Leakage

Turn on the water and gas, checkif there’s any water leakage; also use soapy water or gas leak detector to check if any gas leakage from the gas pipes and fittings.

Turn On Water Heater

Plug in and turn on the water heater. Check whether the water heater ignites and runs successfully.
