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.
