Installation of this product is restricted to indoor locations by licensed plumbing or electrical
contractors only. By installing this product you acknowledge the terms of manufacturer's warranty and
your authorized dealers return policy. Water heaters that have been installed cannot be returned.
If you plan to install your water heater on a second floor/above ground or in a heated attic space you must
follow all code requirements for installation in your area. It is highly recommended to install a drip pan
connected to a safe drain as per code requirements, below the water heater to avoid property damage in
case of eventual leaks, and / or install an active water leak detector and shut off valve to turn off your
water supply in the event that a leak is ever detected.
13. Combustible materials should be kept at least 2 ft away from your water heater and output water pipe.
14. AFTER TIGHTENING BOTH FITTINGS AT THE WATER HEATER OPEN SEVERAL HOT WATER FAUCETS
AND ALLOW WATER TO RUN THROUGH THE WATER HEATER FOR AT LEAST 3 MINUTES. THIS
PROCESS PURGES ALL AIR FROM THE WATER LINES AND HEATER.
HIS PROCESS MUST BE PERFORMED PRIOR TO TURNING ON THE POWER OF THE WATER HEATER.
FAILURE TO FOLLOW THIS STEP CAN CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENT.
