WATER WITH SINGLE-WALL / DOUBLE-WALL  (con't)

 

WARNING: Make sure valve is piped to a 
proper drain per instructions. Scalding 
injury and/or water damage can occur 
from either the manual lifting of the lever 
or the normal operation of valve if it is 
not piped to a proper drain. Insure that 
the safety relief valve piping is of the 
proper material and rating for the 
temperature and pressure of the system 
and that it is secured to prevent possible 
injury. If valve fails to flow water or 
reseat, consult the factory.

 

 
 

CAUTION: The relief valve is a primary 

safety device. 

 

3.  The temperature limiting device and 

thermostat sensors that extend into the 
water in the tank may become coated 
with scale, depending on the type of 
water in your area. This coating will 
affect the accuracy of the sensors and 
can allow the water temperature to 
exceed the desired limits. They should 
be removed from the tank and inspected 
at intervals. Remove scale if present. 

 
CAUTION: On control systems using 120 

volt external power, be certain switch 
is off, and power disconnected to 
avoid electrical shock before work is 
performed on this heater.

 

 
 

 

 
 

Since PVI cannot control the use of the water heater, water conditions, or maintenance, 
the warranty on the water heater does not cover poor performance, structural failure, or 
leaking due to an excessive accumulation of scale.
