Kenmore 153.33204 User Manual

16

The appliance and its gas connection must be leak tested before placing 
the appliance in operation.

The appliance and its individual Shut-off valve shall be disconnected 
from the gas supply piping system during any pressure testing of 
that system at test pressures in excess of 1/2 pound per square inch 
(3.5 kPa).  It shall be isolated from the gas supply piping system by 
closing its individual manual Shut-off valve during any pressure testing 
of the gas supply piping system at test pressures equal to or less than 
1/2 pound per square inch (3.5 kPa).

Connecting the gas piping to the gas control valve of the water heater 
can be accomplished by either of the two methods shown in Figures 
18 and 19.

Contaminants in the gas lines may cause improper operation of the gas 
control valve that may result in fi re or explosion.  Before attaching the 
gas line be sure that all gas pipe is clean on the inside.  To trap any 
dirt or foreign material in the gas supply line, a drip leg (sometimes 
called a sediment trap) must be incorporated in the piping.  The drip leg 
must be readily accessible.  Install in accordance with the “Gas Piping” 
section. Refer to the current edition of the National Fuel Gas Code, 
ANSI Z223.1/NFPA 54.

A sediment trap shall be installed as close to the inlet of the water heater 
as practical at the time of water heater installation. The sediment trap 
shall be either a tee fi tting with a capped nipple in the bottom outlet or 
other device recognized as an effective sediment trap. If a tee fi tting  is 
used, it shall be installed in conformance with one of the methods of 
installation shown in Figures 18 and 19. 

Never use this water heater unless it is completely full of water.  To prevent 
damage to the tank, the tank must be fi lled with water.  Water must fl ow 
from the hot water faucet before turning “ON” gas to the water heater.

To fi ll the water heater with water:

1.  Close the water heater drain valve by turning the handle 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.  

3.  To insure complete fi lling of the tank, allow air to exit by opening the 

nearest hot water faucet.  Allow water to run until a constant fl ow is 
obtained.  This will let air out of the water heater and the piping.

4.  Check all water piping and connections for leaks.  Repair as 

needed.

1.  This power vented water heater comes with the blower assembly 

installed.

2.  After the unit is set in place, make sure the blower assembly is still 

mounted securely and the air intake screen of the blower assembly 
is installed in the dilution air opening.  Also make sure the drain port 
of the rubber boot vent adapter is capped off. Lastly, make sure there 
is no damage to the blower.

3.  Make sure there is no packing material in the discharge of the blower 

or the intake of the dilution air restrictor, see Figure 21.
