III. I NSTALLATION
A. 8298F 2.0 Deck Mount Adapter
Attach the 8298F 2.0 flange to a 3” 150# ANSI flat faced steel companion flange on the water supply
pipe (See kit #81315001 on Pg. 6). Seal the flange joint with a full-face gasket, or a suitable flange
sealant. Fasten the flanges with four 5/8-11 UNC 2½” long grade 5 steel or stainless steel bolts and
compatible nuts. Apply Loctite
® #242 Thread Retainer to the bolt threads, then thread all nuts on hand
tight, and torque them to 60-70 ft-lbs in a crisscross pattern in 20 ft-lb increments.
Caution:
When installing 8298F 2.0 adapter on a companion flange it is critical that the
bolts be tightened uniformly to prevent cocking of the monitor relative to the flange or valve. If the
monitor becomes cocked, (see Fig. 11) the 8298F 2.0 cast flange will fracture and fail when the bolts
on the "high" side are tightened. Do not mount the 8298F 2.0 on a raised face companion flange. A
flat-faced companion flange kit is available from Elkhart Brass (P/N 81315001).

Improper Flange Installation
B. 8298P 2.0 Deck Mount Adapter
Attach the 8298P 2.0 to the 3” NPT male thread on the water supply pipe. Seal the joint with a suitable
pipe thread sealant. Tighten the 8298P 2.0 with a strap wrench or any other wrench that won’t mar any
of the 8298P 2.0’s surfaces. Damage to any surfaces may interfere with installation of the upper
monitor assembly and/or 8298EX 2.0. Do not use the alignment pins on the 8298P 2.0 as lugs to
tighten the adapter, they may bend causing interference with installation of the 8298EX 2.0.
Warning:
The piping must be able to withstand a horizontal reaction force of at least 900
lbs at the height of the discharge elbow and from any angle of rotation that the monitor is capable of
turning. Additional support is required if the 8297 Stinger 2.0
® is going to be used with an 8298EX
2.0. Serious injury to personnel and damage to equipment can result from improper installation.
