FIGURE 30: Downflow Condensate Drain Hose Configuration
Horizontal Left Air Flow (Inducer Low) -
Refer to Figures 31 & 32
1.Remove all the condensate hoses inside the furnace, leaving the 3/8" barbed nipple and hose # 4, both factory installed, in the rain gutter.
2.Remove the condensate trap and its bracket from inside the fur- nace, saving the screws for use later.
3.Remove the yellow cap from the top drain of the rain gutter and install loosely packed 3/8" barbed nipple in it.
4.Remove the large condensate cap from the side of the condensate pan and install it on the middle drain of the condensate pan, from where #1 hose was removed.
5.Install longer dogleg end of hose #10 through the casing hole on to the side drain of the condensate pan, where cap was removed in step #4. Some lubricant may have to be used to facilitate this installation as the hose is designed as a tight fit over the conden- sate drain. The other, shorter, dogleg end of hose #10 should be installed into the large recessed drain in the condensate trap.
6.Install the condensate trap bracket, with the condensate trap, on to the front side of the furnace, using the screws removed in step #1.
7.Switch the blocked condensate hose to the condensate tap on the bottom of the condensate pan (close to the inducer).
8.Install hose #9 between the external drain on the Wye and the condensate trap; with the dogleg end installed on the protruded (stub) drain of the condensate trap. The length of hose #9 may have to be trimmed to ensure proper condensate drainage.
9.Remove all condensate hoses off the 3/8" barbed tee.
10.Cut
11.Install one end of the 3/8" barbed tee on hose #4 as shown. Ensure that hose #4 follows a gradual downward slope all the way to the barbed tee.
12.Install hose #6 between the top drain of the rain gutter of the inducer and the remaining open end of 3/8" barbed tee.
13.Ensure that all hoses are properly installed, have no kinks, and are draining properly. All hoses on the condensate trap should be pushed all the way down to ensure against leakage.
