SAFE SERVICING PRACTICES 

To avoid the possibility of personal injury and/or 
property damage, it is important that safe 
servicing practices be observed. The following 
are examples, but without limitation, of such 
practices: 

 

1. Do not attempt a product repair if you have 
any doubts as to your ability to complete it in a 
safe and satisfactory manner. 
 
2. Before servicing or moving an appliance: 
• remove fuse. 
•  turn off gas supply. 
•  turn off water supply. 
 
3. Never interfere with the proper operation of 
any safety device. 
 
4. USE ONLY REPLACEMENT PARTS 
CATALOGED FOR THIS APPLIANCE. 
SUBSTITUTIONS MAY DEFEAT COMPLIANCE 
WITH SAFETY STANDARDS SET FOR HOME 
APPLIANCES. 
 
5. GROUNDING: The standard color coding for 
safety ground wires is GREEN or GREEN with 
YELLOW STRIPES. Ground leads are not to be 
used as current carrying conductors.   
IT IS EXTREMELY IMPORTANT THAT THE 
SERVICE TECHNICIAN RE-ESTABLISH ALL 
SAFETY GROUNDS PRIOR TO COMPLETION OF 
SERVICE. FAILURE TO DO SO WOULD CREATE A 
POTENTIAL HAZARD. 

6. Prior to returning the product to service ensure 
that: 

 

all electric, gas, and water connections are 

correctly and securely connected. 

 

all gas and water connections are tested for 

leaks. DO NOT TEST FOR GAS LEAKS WITH A 
FLAME. 

 

all electrical leads are properly dressed and 

secured away from sharp edges, 
high-temperature components and moving 
parts. 

 

all uninsulated electrical terminals, connectors, 

heaters, etc. have adequate spacing from all 
metal parts and panels. 

 

all safety grounds (both internal and external 

to the product) are correctly and securely 
connected. 

 

all panels are properly and securely 

reassembled. 

 
 

CAUTION! 

When servicing a water-using 

appliance in a location where the water supply 
has not been in use for an extended time (such 
as vacation) open the hot water faucet at the 
sink and allow the water to run for several 
minutes allowing water and accumulated 
hydrogen gas to escape. Make sure there are no 
open flames (pilots) or cigarettes near the 
faucet. 

 

 

 

 

A lightning flash symbol, within a triangle. is 
intended to alert the user to the presence of 
uninsulated “dangerous voltage” within the 
product’s enclosure that may be of sufficient 
magnitude to constitute a risk of electric shock to 
persons. 

An exclamation point within a triangle is intended 
to alert the user to the presence of important 
operating and maintenance (servicing) instructions 
in the literature accompanying the appliance. 

 

CAUTION

 

 

RISK OF ELECTRIC SHOCK 

DO NOT OPEN

 

 

CAUTION: 

TO REDUCE THE RISK OF 

ELECTRIC SHOCK DO NOT REMOVE 
COVER OR BACK. DO NOT EXPOSE TO 

RAIN OR MOISTURE. 

NO USER SERVICABLE PARTS INSIDE. 

REFER SERVICING TO QUALIFIED SERVICE 

PERSONNEL. 

WARNING: 

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT 

EXPOSE THIS PRODUCT TO RAIN OR MOISTURE.
