Relief Valve Requirements (T&P)
All water heaters must be fitted with a proper temperature and pressure relief valve. These valves must be certified as meeting the requirements of the "Standard For Relief
Valves For Hot Water Supply Systems, ANSI Z21.22/CSA 4.4".
Flooding/Freezing
If this water heater has been exposed to flooding, freezing, fire or any unusual condition, do not put it into operation until it has been inspected and approved by a qualified service technician. THESE CONDITIONS CAN RESULT IN UNSEEN INTERNAL DAMAGE and are not subject to war- ranty coverage.
CAUTION
Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally two (2) weeks or more).
Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance con- nected to the hot water system. Use caution in opening faucets. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.
III)INSTALLATION Unpacking the Water Heater
WARNING
Excessive Weight Hazard
Use two or more people to move and install water heater. Failure to do so can result in back or other injury.
Important: Do not remove any permanent instructions, labels, or the data label from outside of the water heater or on the inside of panels.
•Remove exterior packaging and place installation com- ponents aside.
•Inspect all parts for damage prior to installation and
•Completely read all instructions before attempting to
assemble and install this product.
If you observe damage to the water heater or any of its com- ponents, DO NOT ASSEMBLE OR INSTALL IT OR MAKE ANY ATTEMPT TO FIX THE DAMAGED PART(S). Contact the place of purchase for further instructions.
•After installation, dispose of packaging material in the proper manner.
IMPORTANT:
This water heater must be installed strictly in accordance with the instructions enclosed, and local electrical, fuel and building codes. It is possible that plumbing connec- tions to the water heater, or the water heater itself, may develop leaks. IT IS THEREFORE IMPERATIVE that the water heater be installed so that any leakage of the tank or related water piping is directed to an adequate drain in such a manner that it cannot damage the building, furni- ture, floor covering, adjacent areas, lower floors of the structure or other property subject to water damage. This is particularly important if the water heater is installed in a

Location Requirements
The water heater must be installed indoors in an area not subject to freezing temperatures and in a vertical position on a level surface. Water heaters located in unconditioned spaces (e.g., attics, basements etc.) may require insulation of the water piping, drain piping and venting to protect against condensation. The power vented series of water heaters are designed to vent the products of combustion horizontally through the wall or vertically through the roof. The blower expels the products of combustion by means of plastic piping to the outdoors without the need for a con- ventional chimney.
Select a location as centralized within the piping system as possible. The heater should be located in an area where leakage of the tank or connections will not result in damage
