When the height H (From vent terminal center line to bottom of heater) is over 2.28m (90 in.), it is a high rise vent pipe arrangement. In this case, the minimum distance “D” from the center of the water heater to the outside wall surface is 560mm (22 in.), and the maximum height of “H” is 3.66m (12 ft.).

Gas Connections

Install the gas piping as indicated in Figure 2A. Use only new pipe and fittings with sound, clean-cut pipe threads. Sealing compound must conform to the applicable code for pipe sealing compound approved for use with natural gas and propane. Use gas piping of adequate sizing to ensure full gas input. All piping must comply with all local codes. In the absence of local codes, piping must comply with the rules stated by the applicable "Natural Gas and Propane Installation Code" CAN/CSA-B149.1or "National Fuel Gas Code" ANSI Z223.1 (NFPA 54). The final connection to the gas control valve is made using 1/2”. NPT pipe.

Inlet gas pressure to the appliance must not exceed the gas pressures marked on the rating plate; 7.0 in. w.c. (1.7 kPa) for natural gas, 14 in. w.c. (3.5 kPa) for L.P. gas. The mini- mum supply pressure for the purpose of input adjustment is 1 in. w.c. (0.25 kPa) above manifold pressure.

The appliance and its individual shut-off valve must be dis- connected from the gas supply piping system during any pressure testing of that system at test pressure in excess of 14 in. w.c. (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to, or less than 14 in. w.c. (3.5 kPa).

The appliance and its gas connection must be leak tested before placing the appliance in operation. It is important to have a readily accessible manual shut-off valve in the gas line supplying the water heater. This shut-off valve must be close to the heater. In addition, a drip leg must be installed ahead of the gas control valve to help trap sediment and for- eign material.

A ground-joint union must be installed ahead of the gas

valve to permit easy removal of the unit. All leak testing must be done with a soapy water solution.

NEVER USE A MATCH OR OPEN FLAME TO TEST FOR GAS LEAKS. A FIRE OR EXPLOSION COULD RESULT.

Gas Supply

DANGER

Explosion Hazard

•Use a new CSA approved gas supply line.

•Install a gas supply shut-off valve.

•Do not connect a natural gas water heater to a L.P. gas supply.

•Do not connect a L.P. gas water heater to a natural gas supply

•Failure to follow these instructions can result in death, an explosion or carbon monoxide poisoning.

Read the data plate to be sure the water heater is made for the type of gas you will be using in your home. This information will be found on the data plate located above the gas control valve. If the information does not agree with the type of gas available, do not install or attempt to start. Call your dealer.

Note: An odourant is added by the gas supplier to the gas used by this water heater. This odourant may fade over an extended period of time. Do not depend upon this odourant as an indication of leaking gas.

Water Piping

Pipes and fittings should be installed in compliance with the installation drawing. Check for dip tube in cold water fitting before connection of hot and cold water lines. It is recom- mended that a shut-off valve be located in the cold-water supply line in close proximity to the cold water inlet of the water heater. Show the user where this water shut-off valve is installed and how to use it to shut the water supply to the heater off.

Connect the cold water supply (3/4” NPT) to the fitting marked “COLD”, the hot water outlet (3/4” NPT) to the fitting marked “HOT”. Do not apply heat to either of these fittings as they contain a nonmetallic tube. Solder the pipe to an adapter before attaching the adapter to the hot and cold water fittings. When making these connections, always use a good grade of pipe joint compound and be certain that all fittings are tight. See installation drawing (Figure 2A).

After piping has been installed, allow tank to fill with water and check connections for leaks. To ensure complete filling of the tank, allow air to exit by opening the nearest hot water faucet until a constant flow of water is obtained.
