GENERAL INFORMATION This gas-fired water heater is design certified by the CSA International under the applicable American National Standard, Z21.10.1 or Z21.10.3-(as indicated on the rating plate) and CSA 4.1-(as indicated on the rating plate). 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.
General Information continuedTo comply with NSF requirements this water heater is to be: a) Sealed to the floor with sealant, in a smooth and easily cleanable way, or b) Installed with an optional leg kit that includes legs and/or extensions that provide a minimum clearance of 6” beneath the water heater. This water heater has been manufactured for operation at altitudes from sea level to 2000 feet (610m) (unless otherwise specified on the water heater).
Installation continued- DO NOT install the water heater in any location where gasoline or flammable vapors are likely to be present. This water heater MUST be installed indoors out of the wind and weather. The location of this water heater is of the utmost importance. Before installing this water heater, read the installation section of these instructions.
Installation continued- WARNING DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING: Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas. Most people recognize this odor as a “sulfur” or “rotten egg” smell. Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.
Installation continued- Minimum Clearances From Combustible Materials A 0” (0cm) Left, 2” (5.08cm) Right (113.6 Liters Only) B 0” (0cm) C 4” (10.16cm) D 78” (1.98m) m VENT ---- Figure 1 Venting WARNING The vent system must be installed properly. Failure to properly install the vent system could result in property damage, personal injury, or death. Make certain the flue baffle is in place and centered in flue tube.
TYPICAL INSTALLATION (VENTING) Figure 2 Combustion Air Supply WARNING Liquefied petroleum gases/propane gases are 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. Be sure to smell next to the floor. IF YOU SMELL GAS: Do not try to light any appliance.
Combustion Air Supply continuedAll combustion air must be supplied from outdoors by one of the following installation methods and as illustrated in Figure 2. The flow of combustion and ventilating air must not be obstructed. Adequate air must be supplied for combustion and ventilation. An insufficient supply of air will cause recirculation of combustion products resulting in air contamination that may be hazardous to life.
Water connections continued- WARNING FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4” TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM EXCESSIVE TEMPERATURE AND PRESSURES. If this water heater is installed in a closed water supply system, such as the one having a back-flow preventer in the cold water supply, provisions must be made to control thermal expansion.
Water connections continued- WARNING 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 connected to the hot water system.
Gas Connections The gas supply lines must meet all requirements of 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 Propane Installation Code (Latest Edition). The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. See the rating plate and gas valve for the manifold pressure and gas type.
Gas Conversion Instructions Unless specifically ordered for operation on natural gas, this water heater is normally equipped for operation on liquefied petroleum (LP) gas but may be converted by following these gas conversion instructions. Caution: Make sure gas to be supplied to this water heater following the conversion matches the gas being converted to.
