GOLD GV Series 1 – 4 — Condensate Drain Line Check Valve Kit Instructions
Installation
Step 1
Turn off power to the boiler.
Step 2
If you are using this kit to replace an existing condensate drain line, detach the existing condensate drain
line from the boiler at the jacket.
Step 3
Determine which of the nipples in the kit to use in the vertical position “B” as follows:
•
GV Series 1 Boilers – 21/8" nipple
•
GV Series 2 Boilers – 2½" nipple
•
GV Series 3 and 4 Boilers – 2¾" nipple
Step 4
Determine preferred routing of check valve assembly. Figure 3 and Figure 4 on the next page show
acceptable methods for GV Series 1 and 2 Boilers, while Figure 5 shows the acceptable methods for GV
Series 3 and 4 Boilers.
Step 5
Install the piping with nipple B vertical to keep the check valve assembly as close to the floor as possible.
Step 6
GV Series 1 and 2 Boilers – Clean items “A”, “B” and “C” with CPVC cleaner. Then pre-assemble in the
desired orientation using CPVC cement on the joints. Make sure the bleed hole in elbow “A” is at the top.
See Figure 1 on page 2.
GV Series 3 and 4 Boilers – Clean items “A”, “B”, “C”, “E” and “F” with CPVC cleaner. Then pre-assemble
using CPVC cement on the joints. Make sure the bleed hole in elbow “A” is at the top. See Figure 2, page 2.
Step 7
GV Series 1 and 2 Boilers – Attach elbow A to the condensate drain at the boiler jacket, using CPVC
cleaner and cement. Check the bleed hole to make sure it hasn’t been blocked by cement during the
assembly. Clean out if necessary by hand reaming the hole with a #46 drill bit.
GV Series 3 and 4 Boilers – Attach street ell F to the condensate drain at the boiler jacket, using CPVC
cleaner and cement. Check the bleed hole to make sure it hasn’t been blocked by cement during the
assembly. Clean out if necessary by hand reaming the hole with a #46 drill bit.
Step 8
If desired, you can use nipple “D” to connect the condensate line to the check valve assembly. Clean the
nipple with CPVC cleaner and cement in place with CPVC cement.
Step 9
Connect drain line from check valve assembly (using nipple “D” if desired) to floor drain, making sure
the drain line runs level or continuously downhill. Drain line must not be higher than the check valve.
Do not allow the drain line to rise above the height of the check valve assembly at any
point. This could prevent the check valve from removing condensate and could damage
the boiler or prevent it from operating. Failure to comply with this warning could
result in severe personal injury, death or substantial property damage.
Step 10 If necessary, provide support(s) under the condensate drain line to make sure it remains in position.
Step 11 If using a condensate drain pump, connect the outlet of the check valve assembly to the inlet of the
pump. Make sure the inlet of the pump is at or below the level of the check valve.
