Connect Gas Supply - Honeywell WV4460E Instructions D'installation

Connect Gas Supply

WARNING
Fire or Explosion Hazard.
Can cause severe injury, death, or property
damage.
Check for gas leaks with soap and water solution any
time work is done on a gas system.
Follow these warnings exactly:
1. IF YOU SMELL GAS:
a. Turn off the gas supply at the appliance service
valve. On LP gas systems, turn off the gas sup-
ply at the gas tank.
b. Do not light any appliances.
c. Do not touch electrical switches or use the
phone in the building.
d. Leave the building and use a phone to call the
gas supplier.
e. If you cannot reach the gas supplier, call the fire
department.
2. The water heater control must be replaced in event
of any physical damage, tampering, bent terminals,
missing or broken parts, stripped threads, or evi-
dence of exposure to heat.
CAUTION
Contamination Hazard.
Can cause the device to malfunction.
Do not use thread tape sealants to seal the gas
supply to the control.
a. Use a pipe dope compound to seal the inlet pipe
thread connection. On LP installations, use a
compound resistant to LP gas.
b. Use only ANSI approved compounds.
All piping must comply with local codes and ordinances or
with the National Fuel Gas Code (ANSI Z223.1 NFPA No.
54), whichever applies. Tubing installation must comply
with approved standards and practices.
1. Ensure that the gas supply is turned off.
2. Use new, properly reamed pipe free from chips. If
tubing is used, make sure the ends are square,
deburred and clean. All tubing bends must be
smooth and without deformation.
3. Run pipe or tubing to the water heater control. If
tubing is used, obtain a tube-to-pipe coupling to
connect the tubing to the control.
4. Install a sediment trap in the supply line to the water
heater control. See Fig. 5.

Fig. 5. Install a sediment trap in the supply line.
5. Apply a moderate amount of good quality pipe com-
pound, leaving two end threads bare. On LP instal-
lations, use a compound resistant to LP gas. See
Fig. 6.
APPLY A MODERATE AMOUNT OF
PIPE COMPOUND ONLY TO PIPE
(LEAVE TWO END THREADS BARE).
Fig. 6. Use moderate amount of pipe compound.
6. Remove the seals over the water heater control inlet
and outlet, if necessary.
7. Connect the pipe to the water heater control inlet to
a maximum of 45 ft-lb of torque. Use a wrench on
the square end of the water heater control. Refer to
Fig. 7.
