Perform Operational Test No. 2
Each model has precise specifications for temperature rise capabilities.
Turn on hot water faucet/fixture/process
A
(min flow rate of 1 .5gpm/5 .7 lpm) . The heater
should activate immediately .
If the water flow exceeds maximum heating capacity of the heater, the temperature of water at the outlet
may be lower than the temperature selected on the controller. See table below to determine maximum
temperature rise capabilities.
