Installation Code Requirements
Canadian Installations
In addition to the installation instructions found in this manual, the heater shall be installed in accordance with the latest edition of CAN/CGA B149.1, B149.2 installation codes and/or any local codes. These shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made.
U.S. Installations
In addition to the installation instructions found in this manual, the heater shall be installed in accordance with the latest edition of the National Fuel Code ANSI Z223⋅1 (NFPA 54) and/or any local codes. These shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made.
Important: All supply equipment, installation, Approvals,
permits, inspections, etc. are the responsibility of the owner of this water heater. Consult your local authorities for regulations specific to your area.
Relief Valves (T&P)
All heaters must be installed with a proper temperature and pressure relief valve. These valves must be certified as meeting the requirements for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21⋅22 in the United States. When in Canada, the Standard for Temperature, Pressure, Temperature and Pressure Relief and Vacuum Relief CAN 4⋅4 is required.
Backflow Prevention
Certain jurisdictions may require the installation of a backflow device (e.g., check valve) in the water supply line. Such a device will require the use of a system expansion tank of adequate size to control the thermal expansion generated during the heating cycle. Consult your water supplier or local plumbing authority.
Important: The supply water meter may have a built-in check
valve device. Contact your local water authority.
Safety Warnings
Ø Water Heaters are heat-producing appliances. To avoid
damage or injury, no materials shall be stored against the heater and provision shall be made to prevent unauthorized contact (e.g. children).
FOR YOUR SAFETY, DO NOT STORE OR USE GASOLINE OR OTHER FLAMMABLE, COMBUSTIBLE OR CORROSIVE VAPORS OR LIQUIDS IN THE VICINITY OF THIS HEATER OR ANY OTHER APPLIANCE.
Ø Hot water produced by this appliance can cause severe burns
due to scalding. The hazard is increased for young children,
-2-
the aged, or the disabled where water temperatures exceed 125° F (52°C). Use anti-scald valves in the hot water system to reduce the risk of scalding at points of use such as lavatories, sinks and bathing facilities. Such precautions must be followed when this heater is operated in combination with dishwashing or space heating applications.
Ø As with all fuel burning equipment, this heater requires an
adequate supply of air for combustion and ventilation. An insufficient air supply can result in poor combustion or the recirculation of the exhaust flue gases. Such a condition can cause sooting or present a fire hazard, which may result in serious bodily harm or death from asphyxiation.
MAKE SURE THE FLOW OF COMBUSTION AND VENTILATION AIR IS NOT RESTRICTED.
Ø 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 professional. THESE CONDITIONS CAN RESULT
IN UNSEEN INTERNAL DAMAGE and are not
subject to warranty coverage.
Safety Warnings
Ø There is a risk in using fuel-burning appliances such as water
heaters. Areas that may not be suitable for water heater installation include those where flammable liquids, gasoline, solvents, adhesives, etc., or engine-driven equipment or vehicles are stored, operated or repaired. Due to the nature of air movement, flammable vapors can be carried some distance from the point of storage. The gas-fired water heater, pilot or main burner flame can ignite these vapors causing a flashback fire or explosion which may result in serious personal injury or death, as well as severe property damage.
(softener salt) or other process chemicals are typical of compounds which are potentially corrosive.
Ø Products of this type should not be stored near the heater.
Air containing these chemicals should not be used as supply to the heater. If necessary, uncontaminated air shall be obtained from remote or outside sources.
Ø HYDROGEN GAS CAN BE PRODUCED IN A
HOT WATER SYSTEM. THIS CAN BE PROBLEMATIC IN SYSTEMS WITH LONG STANDBY PERIODS. HYDROGEN GAS IS EXTREMELY FLAMMABLE 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 connected to the hot water system. 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 THAT IT IS OPEN.
INSTALLATION INSTRUCTIONS
NOTICE
Before installing this water heater consideration and planning must be given to the following details: Ø Heater location. The vent blower can create air noise. Do not
install near sleeping area, in a bedroom or bathroom;
Ø Location of the outside vent terminal; See “Venting” p. 7. Ø Routing and support of the vent piping; Figure 5 page 8. Ø How and where to obtain combustion and ventilation air
supply; See “Air Requirements” page 4.
Ø Position of water supply and placement of water piping for
hot and cold water; See “Water Connections” page 10.
Ø Access for gas supply, electrical power, floor drain and
service. See “Gas Service” pages 10 and 11.
If installation in a garage or shed is the only option, it is recommended that the water heater be elevated a minimum of 18" (45 cm) above the floor level. This may reduce BUT
NOT ELIMINATE the risk of flammable vapors being
ignited. Such installations must be protected from impact or physical damage caused from moving equipment or vehicles.
CHECK LOCAL CODES!
Ø Exposure to air borne chemicals can cause severe corrosion
to the water heater and damage to the venting parts. Air containing vapors from cleaning solvents, pool chemicals, refrigerator or air conditioning refrigerants, laundry detergents or bleaches, waxes, spray can propellants, dry cleaning, photo processing liquids, calcium and sodium chloride
NOTICE
REVIEW SAFETY WARNINGS FOUND IN THE FRONT OF THIS MANUAL BEFORE PROCEEDING.
Location and Clearances
Locate the water heater such that all controls are easily accessible. We recommend that 24" (0.6 m) in front of the heater and 34" (0.9 m) above be maintained for serviceability. Ensure that the water heater is level. See Figure 1. Page 1. and Figure 2 page 4. This heater is designed to safely operate with the following minimum clearances to combustibles.
Front 2" (50 mm) Sides and Rear1" (25 mm) Top 12" (305 mm) Plastic Vent Piping 0" (0.0 mm)
-3-
Locate near a floor drain and in an area where leakage of the tank or water piping will not result in damaging adjacent areas or lower floors of the structure. Where such a location is not available, a suitable drain pan must be installed under this water heater. This pan shall be 1½ “ (40 mm) deep and a diameter that is a minimum of 2" (50 mm) greater than the diameter of the water heater. A suitable pipe properly connected to an adjacent floor drain shall be provided. This heater may be installed in a closet or alcove and is certified for operation on a combustible floor.
WARNING
Do not install directly on carpet. Instead, place the water heater on a metal or wood panel extending a minimum of 3" (75 mm) from all sides. In alcoves or closets, cover the carpet completely. Ensure that this panel is capable of supporting the weight of this heater when filled with water.
FAILURE TO PROPERLY INSTALL THIS HEATER MAY RESULT IN A FIRE HAZARD.
II) AIR REQUIREMENTS
General.
Ø An adequate air supply shall be provided for
combustion and ventilation of this water heater. An insufficient supply can result in poor combustion and possible sooting of the burner, combustion chamber or flue passageway. This may present a potential fire hazard or could create a serious health hazard by producing carbon monoxide.
Where an exhaust fan or any other air consuming appliance (Eg. Clothes dryer, furnace, etc.) is installed in the same space as the water heater, sufficient air openings must be available to provide fresh air when all appliances are operating simultaneously. The area in which the heater is located is classified as either “an unconfined space” or “a confined space.”
An unconfined space is defined as a space having a volume not less than 50 cubic feet per 1000 BTU/hour (4.8 cubic meters per kilowatt) of combined input rating of all appliances using the space. Adjacent open rooms may be included as part of the unconfined space. There shall be no closeable doors between these rooms. An example of this is an open basement.
A confined space is one smaller than described above. Air shall be supplied through permanent openings as described in Figures 3 and 4. At no time shall an air opening have a dimension of less than 3" (75 mm) and at no time shall any top opening be lower than the top of the water heater.
For buildings that are not well sealed (do not have tight fitting doors and windows) natural air infiltration may provide sufficient air required for combustion and ventilation. For buildings using tight construction (newer and renovated structures), the air supply shall be introduced from the outdoors, regardless of whether the space is confined or unconfined.
Combustion Air “Supply” Ducts
Air supply ducts shall be of galvanized steel or equivalent corrosion resistant material. A single air duct may not be substituted when required for upper and lower air openings. Horizontal upper combustion air ducts shall not slope downward toward the air inlet.
Louvers and Grills
Openings for air supply ducts must provide free unobstructed air movement. Louver and grill openings must be sized to ensure that the FREE OPEN AREA is never less than the area of the air duct.

Air Requirements for Canadian
1B 2
Installations
Canadian Codes allow for the use of a single air supply source. Canadian customers and authorities having jurisdiction may use the sizing listed in Table 1. Check Local Codes.
When using a single air supply, the duct shall terminate within 1 foot (30 cm) above and within 2 feet (60 cm) horizontally from the burner level of the appliance having the largest input as shown in Figure 3 (b), (c) and (d).
An opening shall be located neither more than 18 inches (450 mm), nor less than 6 inches (150 mm), above floor level. See Figure 3 (b), (c) and (d).
Two permanent openings shall be provided connecting the confined space (e.g., closet/small room) with the unconfined space. Each opening shall have a free area of one square inch per 1,000 BTU/hour input (5.5 cm²/kW) of all appliances in the confined space. The top opening shall commence within 12" (30 cm) of the top of space and the bottom opening shall commence within 12" (30 cm) of the bottom of the enclosure. See Figure 3 (a).
All exterior vent openings are to be clear of snow levels.
