Filling The Water Heater; Venting - Kenmore 153.33525 Owner's Manual

Filling the Water Heater
CAUTION
Never use this water heater unlessit is completely filled
with water. To prevent damage to the tank, the tank must
be filled with water. Water must flow from the hot water
faucet before turning "ON" gasto the water heater.
To fill the water heater with water:
1. Close the water heater drain valve by turning the han-
dle to the right (clockwise). The drain valve is on the
lower front of the water heater.
2. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is |rl use.
3. To insure complete fillin_ of the tank, allow air to exit
by opening the nearest hot water faucet. Allow water
to run unti/a constantflow is obtained. This will let air
out of the water heater and the piping.
4. Check all new water piping for leaks. Repairas needed.

WARNING
VENT DAMPERS - Any vent damper,whether it is operated
thermally or otherwisemust he removedif its useinhlbits
proper drafting of the water heater.
Thermally OperatedVent Dampers:Gas-firedwater heaters
having thermal efficiencyin excess of 80% may producea
relatively low flue gastemperature.Suchtemperatures maX
nut be high enoughto properly open thermally operated
v_nt dampers. Thlswould causespillageof flue gasesand
may causecarbon monoxidepoisoning.
Vent dampersmust bear evidenceof-certificati0n as com-
plying with the latest edition of the American National
Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,
cover electricallyand mechanically actuatedvent dampers).
Before installation of any vent damper, consult the local
SearsService Centeror gasutility for further information.
WARNING
To insure proper ventingof this gas-firedwater heater,the
correctvent p}_oe d iametermustbe utilized.Any additions or
deletionsof otEergasappliances on a commonventwith this
waterheater may adversely affect the operationof the water
heater.Consultthe localSearsService(_enter or gasutility if
anysuch changes are planned.
For proper venting in certain installations, a larger diameter
vent pipe may be necessary. Due to great variances in
installations, unforeseeable by the manufacturer of the
water heater, you must consult your gas company to aid
you in determining the proper venting for your water heater
from the vent tables in the latest edition of the National Fuel
Gas Code ANSI Z223.1, also referred to as NFPA 54.
Check the venting system for signs of obstruction or deterio-
ration and replace if needed.
The combustion and ventilation air flow must not be
obstructed.
WARNING
/
Obstructed or deteriorated vent systems may present[
serious health risk or asphyxiation.

1. Place the draft hood legs in the receiving holes on the
top of the water heater. The legs will snap in the holes
to give a tight fit.
2. Place the vent pipe over the draft hood. With the vent
pipe in position, drill a small hole through both the
vent pipe and draft hood. Secure them together with a
sheet metal screw.

VENT PIPEINSTALLATION
There must be a minimum of 6 clearance betweensingle wa I
vent pipe and any combustible material. Fill and seal any clear-
ance between single wall vent pipe and combustible material
with mortar mix, cement, or other noncombustible substance.
Forother than single wall, follow vent pipe manufacturer's clear-
ancespecifications.To insurea tight fit of the vent pipe in a brick
chimney,sealaround the vent pipe with mortar mix cement.
WARNING
Failure to have required clearancesbetween vent piping
and combustiblematerial will resultin afire hazard.
