GCV3412 CODE VALVE INSTALLATION INSTRUCTIONS
Copper Pipe
1. Turn off water supply.
2. Clean pipe, fittings and valve with sandpaper or wire brush.
3. Apply a thin layer of flux to all surfaces to be soldered.
4. Assemble valve to pipe and/or fittings.
5. Cooling the valve by wrapping a wetted rag around the valve is
optional.
6. Heat the joints with a torch. Apply solder to each joint. Continue to
apply heat sufficient to keep solder liquid.
7. After solder has filled entire joint area, remove heat and allow joint
to cool. Do not move or disturb.
8. Slide compression nut over 1/4" copper tube followed by
compression sleeve.
9. Insert tube into valve fully and tighten nut.
10. Turn on water supply and check for leaks.

Connect 1/4" water supply tube to brass filter at inlet of solenoid. DO
NOT USE PLASTIC TUBING IN CONTACT WITH ANY HOT
PLENUM SURFACE OR DUCT. IF USING PLASTIC TUBING, USE
TUBE SUPPORT P189 AND PLASTIC COMPRESSION SLEEVE
P190.

Turn damper knob to winter (open) position. Turn on water
supply and check operation of humidifier. Set humidistat to a demand
setting. With the furnace off, the solenoid valve should be closed.
Start the furnace, the solenoid valve should open when the blower or
burner circuit is energized. Check flow of water through distributor
trough and evaporator pad. The standard GA4231 yellow orifice will
supply approximately 3.5 GPH of water at a line water pressure of 60
psi. For low water pressures (20-40 psi) a larger orange orifice
GA4299 is available to provide the same flow. Leave humidistat set
at the recommended setting.
Connect drain hose to 1/2" spout on humidifier cabinet using hose
clamp. Run 1/2" hose to suitable drain such as floor drain, sewer or
laundry sink. Be sure hose has continuous slope and is not kinked at
any point.
