INSTALLATION
• Sign in the wall to make the hole “A”.
• Drill the wall by using a 1/4” drill.
• Insert the two plastic expansion anchors
supplied in the installation kit, in the holes.
• Insert two of the four screws
supplied in the holes letting
them stick out from the wall for
at least 5 mm (see fig. aside)
• Hook the appliance and label
the holes B.
• Remove the appliance and by
using the same drill as before,
drill the holes. Insert the removing 2 plas-
tic anchors.
• Hook the appliance and fix it in the lower
part, by using the remaining 2 screws.
CONNECTING TO GAS SUPPLY
IMPORTANT: For natural gas, check gas line
pressure before connecting heater to gas line.
Gas line pressure must be no greater than 14
inches of water. If gas line pressure is higher,
heater regulator damage could occur.
For propane/LP gas, the installer must supply
an external regulator. The external regulatr
will reduce incoming gas pressure to between
11 and 14 inches of water. If you do not
reduce incoming gas pressure, heater regula-
tor damage could occur. Install the external
regulator with the vent pointing down as
shown in figure 6. Pointing the vent down pro-
tects it from freezing rain or sleet.

WARNING: This appliance requires a 3/8”
NPT (National Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified service person must
connect heater to gas supply. Follow all local
codes.
WARNING: For natural gas, never connect
heater to private (non-utility) gas wells. This gas
is commonly known as wellhead gas.
CAUTION: For propane/LP gas, never connect
heater directly to the propane/LP supply. This
heater requires an external regulator (not sup-
plied). Install the external regulator between the
heater and propane/LP supply.

CAUTION: Use only new, black iron or steel
pipe. Internally-tinned copper tubing may be
used in certain areas. Check your local codes.
Use pipe of large enough diameter to allow
proper gas volume to heater. If pipe is too small,
undue loss of volume will occur.
