pressure, replace gas valve if found to
be defective, repair or replace wire if
defective.
Replace electrode, module board,
gas valve, or electrode wire if found
defective. Clean or replace burner
tube, correct gas pressure.
Replace electrode or wire if defective,
clean electrode tips with Emory cloth,
adjust electrode if sparking incorrectly,
clean or replace burner tube.
To reset the appliance from LOCKOUT
mode, turn the power switch off for

130 degrees F, plus or minus 5 degrees F
• Install air pocket in tank, conrm water temperature is within operating range
130 degrees F, plus or minus 5 degrees F, inspect relief valve for signs of
contamination at seal
• Check for proper gas pressure (11”WC-14” WC), inspect burner .....................
ue tube, and vent for debris
Set by-pass valves to correct position,
close open mixing valves, replace
thermostat if defective, replace diffuser
tube (‘s).
Replace or secure thermostat
Replace thermostat or relief valve
if found to be defective, install
accumulator tank to plumbing system
per manufacturers installation
instructions.
Set to correct gas pressure, replace
valve if found to be defective, clean or
replace burner tube, clean ue tube
and vent assembly.
