Install low voltage wiring (14 or 16 ga. 24VAC) underground between
the control panel and each burner assembly. Wire per Grand Effects
®
wiring diagram. 120v source into the control panel can come from any
120v source, including auxiliary relay from the pool controller or home
system. Typically, the pool controller is the device that turns the unit on
and off. If a pool controller is not available, Grand Effects can provide a
hand held remote system or an electrician can wire a decorative switch
for on/off control up stream of the Grand Effects control panel.
6. Maintain good piping practice by keeping pipe length and elbows to
a minimum to eliminate unnecessary pressure drops. Corrugated flex
gas lines should not be used.
7. The Support Plate can be installed in a few different methods. Smaller
Support Plates can be supported using legs (threaded rod) supplied
by Grand Effects. When using threaded rod, adjust the height of the
support plate as shown in Figures 5, 6 and 7. Cut off the excessive
length of bolts. When using threaded rod as legs, the bottom of the
fire pit should be concrete to support the weight of the Support Plate,
Burner Assembly and decorative media. When using larger Support
Plates, stainless “L” brackets may be sufficient to hold Support Plate
and burner assembly and media. If not, then structural galvanized
angle iron cross members should be included. Cross member supports
should be fixed and laid across fire pit in a rigid manner to hold
Support Plate, Burner Assembly and decorative media.Venting the air
gap at the bottom of the fire pit walls is required for cooling the burner
assembly as shown in Figure 5 and Figure 6.
