Connect Gas Supply - Honeywell WV4262B Installation Instructions Manual

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 ser-
vice valve. On LP gas systems, turn off the
gas supply 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 evidence 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 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. 4.

Fig. 4. Install a sediment trap in the supply line.
5. Apply a moderate amount of good quality pipe
compound, leaving two end threads bare. On LP
installations, use a compound resistant to LP
gas. See Fig. 5.
APPLY A MODERATE AMOUNT OF
PIPE COMPOUND ONLY TO PIPE
(LEAVE TWO END THREADS BARE).
Fig. 5. 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 40 ft-lb of torque. Use a wrench
on the square end of the water heater control.
Refer to Fig. 6.
