Appliance Preparations
Appliance Mounting
1. Obtain assistance in lifting the appliance
onto the wall bracket.
2. Install the appliance making sure the appli-
ance mounting lip located along the upper
edge of the rear jacket panel engages the
wall-mounting bracket. Ensure the appli-
ance is seated properly and is secure.
Piping Support Bracket
Appliance must be installed using the sup-
plied copper fittings and piping support
bracket. DO NOT braze directly to cop-
per appliance pipes or damage may result
to internal parts (gaskets and flow switch).
1. Pre-install the 4 brass compression fittings
into the piping support bracket as shown in
Fig. 4, page 15. Use retaining clips to hold
fittings in place.
Apply pipe joint compound suitable for
potable water systems to the compres-
sion ferrule and compression nut threads
of all brass fittings before installation.
Install appliance pipes into the fittings
until bottom of hex on gas pipe fitting
rests against the top of the piping sup-
port bracket before tightening any com-
pression nuts. Do not over tighten com-
pression nuts. If fitting leaks loosen com-
pression nut first and then retighten.
2. Prior to mounting the appliance on the wall
and with the rear or back of appliance lay-
ing flat, slip the appliance piping into the
fittings until bottom of hex on gas pipe fit-
ting rests against the top of the piping sup-
port bracket before tightening any com-
pression nuts.
3. Tighten all fittings to appliance piping
connections with two wrenches.
Use a two wrench method when tighten-
ing piping near the appliance and its pip-
ing connections. Use one wrench to pre-
vent the appliance connections from
turning and the second to tighten adja-
cent piping. Failure to support the appli-
ance piping connections could damage
piping.
4. Once appliance is mounted according to
Appliance Mounting instructions on this
page, secure piping support bracket to wall
with hardware supplied.
