    Such a condition often will result in a yellow, luminous burner flame, causing sooting of the combustion chamber, burners and flue tubes and creates a risk of asphyxiation. Do not install the water heater in a confined space unless an adequate supply of air for combustion and ventilation is brought in to that space using the methods described in the Confined Space section that follows.

    Note: In addition to the factory installed Temperature-Pressure Relief Valve on the water heater, each remote storage tank that may be installed and piped to a water heating appliance must also have its own properly sized, rated and approved Temperature-Pressure Relief Valve installed.

  • Page 17: Temperature-Pressure Relief Valve

    If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions in this manual, and replace the Temperature-Pressure Relief Valve with a properly rated/sized new one.

    Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater. To fill the water heater with water: 1. Close the water heater drain valve by turning handle to the right (clockwise). The drain valve is on the lower front of water heater. 2. Open the cold water supply valve to the water heater.

See Figures 17, 20 and 21. condensate This water heater is a condensing unit and requires a drain to be located in close proximity to allow condensate to drain safely. One hose from blower housing, two flexible hoses from blower outlet adaptor, along with another flexible hose from VAA if installed, run to barb fittings on vent pipe assembly #2. Hose is clamped by rubber clips and flexible hoses by a clamp on jacket top cover. See Figure 17. Condensate drains from the unit at the exhaust tee located at the bottom of the unit (see figure 16). Condensate from this water heater is mildly acidic. Please note...

  • Page 22: Condensate

    The condensate trap may be primed by filling the CONDENSATE U-ASSEMBLY with tap water while the water heater is not operating. The system is fully primed when the water level reaches the adaptor connected into the Tee. In most installations the water heater will self-prime the condensate trap during the first full heat-up cycle. If a sound of air bubbling through water (gurgling) is heard while the blower is operating after the first heat-up cycle, then turn the unit off and contact your plumber or service representative.

Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°-15° should be added to the end to permit easier insertion of the pipe into the end of the fitting. Failure to chamfer the edge of the pipe may remove cement from the fitting socket, causing the joint to leak. step B C. Test dry fit of the joint Tapered fitting sockets are designed so that an interfaced fit should occur when the pipe is inserted about 1/3 to 2/3 of the way into the socket. Occasionally, when pipe fitting dimensions are at the tolerance extremes, it will be possible to fully insert dry pipe to the bottom of the fitting socket. When this happens, a sufficient quantity of cement...
