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.

CAUTION 

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.

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.

 

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.

WARNING: 

TO PREVENT FIRE OR SHOCK HAZARD, DO 

NOT EXPOSE THIS PRODUCT TO RAIN OR
