Bradford-White Corp THROUGH-THE-WALL GAS WATER HEATER 사용자 설명서

Note:  BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN 
WATER SUPPLY VALVE. 
After shutting off the main water supply, open a faucet to relieve the water line 
pressure to prevent any water from leaking out of the pipes while making the 
water connections to the water heater.  After the pressure has been relieved, 
close the faucet.  The COLD water inlet and HOT water outlet are identified on the 
top of the water heater.  The fittings at the cold water inlet and hot water outlet 
are dielectric waterway fittings with 3/4” NPT male thread.  Make the proper 
plumbing connections between the water heater and the plumbing system to the 
house.  Install a shut-off valve in the cold water supply line. 
 

 
If this water heater is installed in a closed water supply system, such as one 
having a back-flow preventer in the cold water supply, provisions must be made to 
control thermal expansion.  DO NOT operate this water heater in a closed 
system without provisions for controlling thermal expansion.  Your water supplier 
or local plumbing inspector should be contacted on how to control this situation 

After installation of the water lines, open the main water supply valve and fill the 
water heater.  While the water heater is filling, open several hot water faucets to 
allow air to escape from the water system.  When a steady stream of water flows 
through the faucets, close them and check all water connections for possible 
leaks.  NEVER OPERATE THE WATER HEATER WITHOUT FIRST BEING 
CERTAIN IT IS FILLED WITH WATER. 
 
 
 
 
 
 
 

 

If sweat fittings are to be used DO NOT apply heat to the nipples on top of 
the water heater.  Sweat the tubing to the adapter before fitting the adapter to 
the water connections.  It is imperative that heat is not applied to the nipples 
containing a plastic liner.
