Install Condensate Trap; Gv90+ Suggested Condensate Pump Capacity; Finished Assembly - Weil-McLain GV90+ Manual

GV90+ Series 2
Prepare the boiler

Install condensate trap

1. Before placing the boiler in position, install the condensate trap
line, shown in Figure 7. Items shown are provided with the boiler.
Attach the flue drain hose (C) to the in-line flue drain
nipple (B).
Slide a screw driver or pencil through the condensate
drain nipple (G).
Slide the end of the screwdriver or pencil into the open
end of the flue drain hose (C).
Feed the in-line flue drain (A) assembly into the flue con-
nection (D), guiding the flue drain hose through the con-
densate drain nipple (G) with the screwdriver or pencil.
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 the
end of the condensate drain nipple (G).
Slide the U-clamp (F) over the condensate trap tee (E)
and into the two holes in the rail. Attach the two nuts pro-
vided to the U-clamp and tighten to secure the condensate
trap tee to the rail.
Slide the ends of the condensate trap hose (H) onto the
condensate drain nipple (G) and the condensate trap tee
(E). Secure the condensate trap hose at each end with the
hose clamps (J).
Before rotating the boiler into position, measure the
distance from the condensate tee outlet to the bottom
of the boiler mounting rails. When the boiler is place in
position, the condensate tee outlet must be higher than
the condensate pump inlet connection (when a con-
densate pump is used). Increase the foundation height
if necessary.

GV90+ Suggested Condensate Pump Capacity

The table below contains the suggested condensate pup capacities foe GV90+
boilers. The values below are calculated with assuming all the water vapor
in the flue gases is condensed along a 1" per hour rain load and safety factor.
