Gas Valve
Frymaster's high-effi ciency gas fryers use Honey-
well valves. It is opened by current fl owing through
the spark module.
Testing Gas Valves
The resistance across the contacts for the coils of the
Honeywell valve: 400-650 ohms on the diode setting.
Safety Drain Switch
Drain switches (here shown on an
H55 fryer) break the 24VAC to
the gas valve, preventing the fryer
from heating if the drain valve is
open. These switches are not on
automatically operated valves on the
LOV and FilterQuick fryers.
Burners
The service replacement burner
for the H55 is fi tted with two gas
inlets and ceramics that function
with natural gas or propane. This
approach means the burner will fi t
either side of a vat on a natural or
propane-fueled fryer. The same
approach is taken with smaller
service burners for 30-lb frypots.
The burner must have an airtight fi t to heat effi ciently. Insula-
tion strips are wrapped around the burner rails (above) to en-
sure a good seal. The radiants of a burner glow blue at startup. After approximately 1 minute, a bright orange
glow (right above) should appear. If the burner remains blue,there's an improper gas/air mixture.
