1. Figure 1 There are vent piping configurations when combined with certain environmental conditions that can produce enough condensate to require collection and disposal When a slope away from the water heater cannot be achieved and condensate handling is required in a horizontal vent system the vent pipe should be sloped toward the water heater as shown in Figure 2 Slope Toward Drain Port vA yo ie Drain Ul D Figure 2 e Remove drain port cap e Connect flexible condensate drain tube to the blower drain port e Loop the drain tube so that it has a circular trap See Figure 3 e Secure the top and bottom of the loop with wire ties or plastic zip ties as shown e DONOT restrict any portion of the circular drain tube e Loop must be smooth and not collapse the tube e Fill circular drain tube with water to make sure combustion gases cannot vent into the room e Condensation collected must be discharged per local codes e DO NOT drain over public way or walkway e Refer to local codes for any condensate requirements Water Filled From Drain Port Wire or Zip Ties To Drain f C Figure 3 If the venting system is vertical and condensation handling is required then the blower coupling drain port and tube must be used as described previously Any horizontal portion of the vent pipe must slope toward the water heater at a minimum of 1 8 inch per foo

3. The control will verify the blower vacuum switch has closed ensuring that the blower is functioning properly and that the venting system is not blocked The control will then proceed through a sequence of self diagnostics before initiating a trial for ignition During the trial for ignition the hot surface ignitor will warm up Once the hot surface ignitor warms up the main gas valve will open allowing gas to flow to the main burner Once the main burner ignites the control will verify that the burner flame is present through the flame sense circuit The hot surface ignitor will then turn off The main burner will remain lit throughout the heat cycle until the water temperature setting is reached Once the water temperature setting is reached the control will close the main gas valve which will extinguish the main burner flames The blower motor will stay energized for an additional 30 seconds after the control verifies that the burner flame is extinguished in order to clear combustion gases from the water heater After the post purge sequence the control will de energize the blower motor and go into a stand by mode awaiting the next call for heat This water heater is equipped with a flammable vapor sensor that is monitored continuously by the electronic control in all modes of operation In the event that flammable vapors are detected the control will automatically shut down the water heater and prev
