3.In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a drain tee and condensate trap can be installed in the horizontal vent as close as practical to the blower vent connection (see Figure 2). The condensate disposal tube should be installed to drain any accumulated condensate away from the water heater and to a suitable drain. The drain tee and condensate hose are not available from Bradford White, but should be available through your local distributor.
