Leave an air gap between the hose and the building
drain, and don’t allow water traps in the hose.
Install a WRAS approved double-check valve or an
equally effective backflow preventive device in the
incoming cold water line at the point of connnection(s)
to the steamer and in compliance with all local plumbing
codes. This installation must be per WRAS-IRN R160
Schedule 2-15(1). For units with the dual water
connection option, a double-check valve shall be
installed on each water line.
Do not allow the connection to have any leak, regardless
of how small.
4.5 Drain Connection
The HY-6G (CE)Steamer must be leveled front to back.
A 38mm (1½ inch) ID hose may be attached to the drain
pipe (supplied) by means of a hose. DO NOT
CONNECT THE HOSE DIRECTLY TO A BUILDING
DRAIN. There must be a free air gap between the end
of the hose and the building drain. The free air gap
should be as close as possible to the unit drain. There
must also be no other elbows or other restrictions
between the unit drain and the free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. THE DRAIN MUST
WITHSTAND HOT WATER.
Install the drain line with a constant downward pitch.
IMPORTANT: Do not allow any water traps in the
line. A trap can cause pressure to build up inside the
cavity during steaming, which will make the door
gasket leak.
4.6 Initial Start-Up
After the HY-6G(CE) Steamer has been installed,
test it to ensure that the unit is operating correctly.
4.6.1 Remove all literature and packing materials
from the interior and exterior of the unit.
4.6.2 Make sure the water supply line is open.
4.6.3 Make sure that the gas supply line is open
and that the manual knob on the main gas
valve is turned to the “on” position. This
valve is located behind the front access
panel on the right side of the unit.
4.6.4 Turn on electrical service to the unit. The
HY-6G(CE) will not operate without electrical
power. Do not attempt to operate the unit
during a power failure.
4.6.5 The steamer will not operate until the pilot
burner has been ignited. To light the pilot
burner, activate the pilot switch located at
the lower front, next to the main gas valve.
When the pilot ignition sequence has been
successful, a green light on the pilot switch
will glow.
4.6.6 The “trial for ignition” period is roughly 90
seconds. If the pilot burner does not light
within about 90 seconds after the switch is
activated, the ignition system automatically
stops gas flow to the pilot burner and stops
the ignition trial. If this happens, turn off the
pilot switch and repeat the trial for ignition.
During the initial start-up, the pilot may
require several trials for ignition until all the
air is bled from the gas piping. Subsequent
start-ups should require only about 5
seconds to achieve pilot ignition. Reinstall
panel(s). NOTE: See Automatic Operation of
Pilot at the end of this section.
4.6.7. Once the pilot burner flame has been
established (the green light on the electrical
panel is on), press the ON/OFF touch pad
for the desired steamer cavity. The steam
generator will fill with water.
NOTE: The door MUST be closed for the
main (high) burner to work.
4.6.8 When the steam generator has filled with
water, the main and low burners will ignite
automatically. Within 6-8 minutes the
READY light will come on, indicating that the
water has reached its standby temperature.
When the READY light is displayed, you may
take any one of the following steps:
