Boiler Manual - Weil-McLain

GV90+ gas-fired water boiler — Boiler ManualPrepare the boiler (continued)Install condensate trap1. Before placing the boiler in position, install the condensate trapline, shown in Figure 7. Items shown are provided with the boiler.Step 1 Attach the flue drain hose (C) to the in-line flue drainnipple (B).Step 2 Slide a screw driver or pencil through the condensatedrain nipple (G).Slide the end of the screwdriver or pencil into the openend of the flue drain hose (C).Feed the in-line flue drain (A) assembly into the flue connection(D), guiding the flue drain hose through the condensatedrain nipple (G) with the screwdriver or pencil.Step 3 Press the in-line flue drain (A) into the flue connection(D) and through the seal ring until it reaches the stop.Then tighten the flue connection hose clamp to secure.The flue drain hose (C) should now extend down past theend of the condensate drain nipple (G).Step 4 Slide the U-clamp (F) over the condensate trap tee (E)and into the two holes in the rail. Attach the two nuts providedto the U-clamp and tighten to secure the condensatetrap tee to the rail.Step 5 Slide the ends of the condensate trap hose (H) onto thecondensate drain nipple (G) and the condensate trap tee(E). Secure the condensate trap hose at each end with thehose clamps (J).Check the height of the condensate trap tee outlet.Before rotating the boiler into position, measure thedistance from the condensate tee outlet to the bottomof the boiler mounting rails. When the boiler is place inposition, the condensate tee outlet must be higher thanthe condensate pump inlet connection (when a condensatepump is used). Increase the foundation heightif necessary.Figure 7A In-line flue drainB Flue drain nippleC Flue drain hoseD Flue connectionE Condensate trap teeFInstall condensate trapU-clamp and nuts (notshown)G Condensate drainnippleH Condensate trap hoseJHose clampsFinished assemblyPart number 550-142-054/1211 9
