INSTALLING MANIFOLDED CONDENSATE DRAIN
1.
to determine whether the flue system
requires condensate drainage. If not required,
do not
install a manifolded condensate drain assembly.
2.
Identify the number of condensate tube kits required (Rheem part number AS3312007). One (1)
condensate tube kit is required for each CFWH.
3.
Identify the number of condensate trap kits required (Rheem part number AS3312006). One (1) kit is
required for wall mount and floor mount systems. Two (2) kits are required for back to back systems.
4.
Remove the clamp and rubber cap from the condensate drain spigot on the water heater flue outlet.
Ensure that each spigot is facing towards the right-hand side when facing the CFWH front cover.
Discard the clamp and the rubber cap.
5.
Fit the long silicone tube and aluminium tube included in the condensate tube kit between the CFWHs.
Ensure the silicone tube is not kinked, twisted or pinched and ensure it is not caught on any CFWH
exterior surfaces.
6.
Fit the end of the short silicone tube to the spigot of the water heater flue outlet.
7.
Cut the polyethylene tube included in the condensate tube kit to 348mm. Note: if connecting in-between
two frames, do not cut the tube (357mm). Refer Figure 1.
8.
Connect plastic tubes and plastic fittings to create a plastic tube manifold, refer Figure 1.
a. Use a 90° elbow on the leftmost fitting, provided with the condensate trap kit.
b. Use the tee fitting provided with a condensate tube kit to connect two polyethylene tubes together.
The unused connection on the tee fitting should point upwards.
c. Use the tee fitting provided with a condensate tube kit as the rightmost fitting. The unused
connections on the tee should point vertically.
9.
Connect the condensate trap assembly to the rightmost tee fitting connection facing downwards, refer
Figure 1.
10.
Secure each polyethylene tube connection with the plastic ratchet clamps provided with condensate
tube kits.
11.
Connect each long silicone tube to the upward facing tee fitting connections. Ensure the silicone tube
is not kinked, twisted or pinched.
12.
Affix the condensate trap retaining bracket provided with the condensate trap kit to the frame member
using tek screws provided.
13.
Affix the condensate manifold to the frame member with p-clips provided with the condensate tube kits.
14.
Direct the outlet of the condensate trap to a suitable drain. Plastic elbows are provided to direct the
outlet to a convenient position. The last tube section at the end of the condensate trap assembly may
be cut shorter, however any other section of the trap assembly must not be tampered with.
15.
Remove the short silicone tube on the rightmost condensate elbow assembly and fill the trap with water.
Observe that water freely discharges from the outlet of the condensate trap. Fit the short silicone tube
back on the CFWH flue spigot.
16.
Repeat procedures 4 to 15 on the rear CFWHs for back to back systems. Note: for the rear CFWHs
on back to back systems, use a 90° elbow provided with the condensate trap kit as the rightmost
fitting as outlined in the section 8(c).
