SECTION I: IMPORTANT INFORMATION READ CAREFULLY This gas-fired water heater is design certified by CSA International under the American National Standard, Z21.10.3 (as indicated on the rating plate) and CAN/CGA 4.3-M (as indicated on the rating plate) available from CSA Standards Association, 5060 Spectrum Way, Mississauga, Ontario, Canada L4W 5N6. - Page 3 DANGER DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors and/or liquids in the vicinity of this or any other appliance. This water heater is for outdoor installation only. Do not install indoors. This water heater is equipped with an adjustable thermostat to control water temperature. Hot water temperatures required for automatic dishwasher and laundry use can cause scald burns resulting in serious personal injury and/or death.
- Page 4 WARNING DO NOT tamper with or alter the water heater and/or controls. DO NOT operate water heater with jumpered or absent controls or safety devices. DO NOT operate water heater if any external part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system including gas controls, which has been under water.
- Page 5 WARNING Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas.

Page 67: Warranty
SECTION X: WARRANTY What does this Limited Warranty Cover? This limited warranty covers both the heat exchanger and component parts for leakage or other malfunction caused by defects in materials and/or workmanship. It applies to the original consumer purchaser and to any subsequent owner as long as the water heater remains installed at its original place of installation. - Page 68 On-demand re-circulation is defined as a hot water re-circulating loop or system that utilizes existing hot and cold lines or a dedicated return line, and only activates when hot water is used. It can be activated by a push button, motion sensor, or voice activation but not by a temperature sensor. A timer added to a standard re-circulating pump is not considered as on-demand.
