CSA Standards Association, 178 Rexdale Blvd., Etobicoke, Ontario, Canada M9W 1R3. This water heater must be installed in accordance with local codes. In the absence of local codes, it must be installed in compliance with the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2... - Page 3 DO NOT attempt to use this water heater with any gas other than the type listed on the rating plate. Do not attempt to convert this water heater for use with a gas other than the type for which it is equipped. Failure to use the proper gas can create an unsafe condition resulting in property damage, bodily injury, or death.
- Page 4 90.1b (latest edition) standards with respect to insulation and standby loss requirements. Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance, which is connect to the hot water system.

Page 12: Air Requirements
2. For safe operation, adequate air is needed for combustion and ventilation. Sooting may result in serious damage to the water heater and risk of fire or explosion. It can also create a risk of asphyxiation. Such a condition often will result in a yellow, luminous burner flame, causing carboning or sooting of the combustion chamber, burner and flue tubes. -
Page 13: Chemical Vapor Corrosion
Internet Version for Reference Only If the water heater is installed as a direct vent (outside air piped directly to the water heater), then additional opening, other than the opening for the air intake, are not required. However, adequate ventilation air must be provided in all cases to prevent increased room temperature. - Page 14 Internet Version for Reference Only Figure 6.

The water is under pressure and may splash. If sweat fittings are to be used, DO NOT apply heat to the nipples in front or side of the water heater. Sweat the tubing to the adapter before fitting the adapter to the water connections. It is imperative that heat is not applied to the nipples containing a plastic liner. - Page 16 Failure to properly pipe this water heater may result in improper operation and damage to the water heater or structure.
-
Page 17: Vi Venting
The water heater requires its own separate venting system. Do not connect the exhaust vent into an existing vent pipe or chimney. All of the exhaust venting connections must be leak checked with a soap solution upon initial start up of the water heater. Any leaks must be repaired before continuing operation of the water heater. -
Page 18: Direct Vent Installation
This water heater can be installed as either a direct vent system or power vent (air from inside) system. If it is installed as a direct vent system, then the air intake and the exhaust vent are piped to the outside. If a power vented system is used, then air is drawn from inside and only the exhaust is piped to the outside. - Page 19 Internet Version for Reference Only Figure 12a.
