– 4 – Y our safety and the safety of others is very import ant. We have provided many import ant safety messages in this manual and on your appliance. Always read and obey all safety messages. All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury , and tell you what can happen if the instruc[...]

II) SAFETY This water heater is design-certified by CSA International as a Category III, non-direct vented water heater that takes it s combustion air either from the installation area or from air ducted to the unit from the outside. In addition to the installation instructions found in this man- ual, the water heater must be installed in accordanc[...]

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 "St andard For Relief V alves For Hot W ater Supply Systems, ANSI Z21.22/CSA 4.4" . Flooding/Freezing If this water heater has been exposed to flooding,[...]

Before inst alling this water heater , consideration and planning must be given to the following details: • Proximity to walls and other objects (see "Clearance and Accessibility"). • Access [...]

This gas piping must be installed in accordance with all local and provincial or state codes or , in the absence of such, the latest edition of "Natural Gas and Prop ane Installation Code" CAN/CSA-B149.1 (Canada), or " National Fuel Gas Code" ANSI Z223.1 (NFP A 54) (U.S.A.). Use properly sized gas piping to ensure full gas input[...]

Air Requirements Import ant: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to cor- rosive elements in the atmosphere is excluded from war- ranty coverage. Installations in or for cert ain places including, but not limited to, those listed below may require outdoor air for combus- tion to reduce the ri[...]

Ventilated Space Air Requirements for U.S. Installations Refer to Figure 5 (a), (b), (c) or (d) for proper sizing and location of combustion air ducts and openings. CHECK LOCAL CODES . a) Equipment located in ventilated sp aces; all air from inside the building. T wo permanent openings shall be provided connecting to ventilated space (e.g. closet, [...]

Exhaust Venting This heater is designed to exhaust the products of combus- tion (flue gases) to the outdoors using a sealed piping sys- tem. T able 2 list s the allowable vent materials and sizing information. Figure 8 shows the general venting layout while Figures 9-1 1 show various end termination details and clearances. Connection of the venting[...]

Venting terminations and sizing • Refer to Figure 8 and T able 2 for vent pipe materials and sizing. Examples of the vent terminations are shown in Figures 9 and 10. If the installation requires a vent riser , suitable drainage must be provided to ensure condensation does not accumulate. T ermination through a roof is shown Figure 1 1. • G/JW 4[...]

Venting instructions 1. Plan the venting layout starting at the vent termination and work back toward the heater . T ake into considera- tion the style and position of the vent termination, the vent pipe routing, elbows and connectors required and the necessary support hangers. 2. G/JW 40, 50 and 60-gallon heaters may use 50mm (2 in.) or 76mm (3 in[...]

1 1. Dry fit all vent pipes, elbows, connectors and fittings before joining any part s with solvent cement. P ARTS MUST FIT WITHOUT STRESS OR BENDING OF ANY SECTION and each connection must overlap a mini- mum of 13mm (1/2 in.). Do not force fit any of the con- nections. Use only the appropriate solvent cement. Caution: Solvent cements may produce [...]

Water Supply Piping Installation Piping, fittings, and valves should be installed according to the installation drawing (Figure 16). A pressure-reducing valve and/or an expansion t ank may be required for instal- lations where the water pressure is high. The pressure- reducing valve should be located on the supply to the entire house in order to ma[...]

Closed System/Thermal Expansion Periodic discharge of the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may cont ain a check valve, backflow preventer or water pressure-reducing valve. This will create a closed water system. During the heating cycle of the water[...]

Electrical Supply Import ant: The electrical controls used inside the gas con- trol/thermostat of this water heater are polarity sensitive . Ensure the electrical supply is connected correctly in the receptacle box. Failure to connect correctly will prevent the unit from functioning properly (see Figures 19 & 20). Before performing any electric[...]

Flammable Vapour Sensor When using a gas fired water heater there is a risk of flam- mable vapours entering the combustion chamber , being ignited by the burner flame and causing a flashback. In order to detect such flammable vapours before they enter the combustion chamber , this water heater is equipped with a flammable vapour sensor (FVS). It is[...]

rounding area for damage and call a qualified service tech- nician to service the water heater and replace the flamma- ble vapour sensor . If there is a problem with the wiring of the flammable vapour sensor or the flammable vapour interface the LED will flash the failure status code. Resettable Lockout The gas control/thermostat can be reset by un[...]

Installation Checklist Check Here Water Heater Location 1. Centrally located with the water piping system. Located as close to gas piping and vent pipe system as possible. 2. Located indoors and in a vertical position. Protected from freezing temperatures. 3. Proper clearances from combustible surfaces maintained and not inst alled directly on a ca[...]

IV) OPERATING INSTRUCTIONS Temperature Regulation This water heater ’ s intended purpose is to heat water . Hot water is needed for cleaning and sanitizing (bodies, dishes, clothing etc.). Untempered hot water can present a scald hazard. Depending on the time element and the people involved (adults, children, elderly , infirm etc.) scalding may o[...]

This control is a combination gas valve, ther- mostat and ignition controller for use on this power vented water heater . The valve contains a microcomputer that supervises the ignition seq[...]

Note: All the temperature indicators will be off during normal operation. If any time you see the indicators on, there may be a system error and you should consult the “T roubleshooting” section of this document, or contact a trained service professional. There is a hot-water scald potential if the thermostat is set too high. In households with[...]

– 27 – The self-diagnostic test has detected that the water tem- perature sensor is either open or short circuited. 1. Turn the power of f for 10-20 seconds then on again to clear this error code. 2. If no wiring problems are found the control must be replaced. The self-diagnostic test found a problem with the Flammable V apour Wiring. 1. Check[...]

V) OPERATION Burner Flames Inspect the burner flames through the viewport and com- pare them to the drawings in Figure 26. A properly operat- ing burner should produce a soft blue flame. Blue tip s with light blue inner cones are satisfactory . The tips of the flame may have a slight yellow tint. The flame should not be all yellow or have a sharp b[...]

Anode Rod Replacement T o replace the anode: 1. T urn off gas supply to the water heater . 2. Shut off the water supply and open a nearby hot-water faucet to depressurize the water tank. 3. Drain approximately 20 litres (5 US gallons) of water from tank (Refer to "Draining and Flushing" for proper procedures.) Close drain valve. 4. Remove[...]

Venting System and Blower Inspect the venting system periodically (minimum twice annually) to make certain that the vent p assageways, vent terminal and blower assembly are free and unobstructed. Ensure that any condensate is draining freely . Clean as nec- essary . • Inspect the vent piping, elbows and connections for signs of stress cracking or[...]
