WARNING: If you smell gas:

• Shut off gas supply.

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any phone in your

building.

• Immediately call your gas supplier from a neighbor's phone. Fol-

low the gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire department.

WARNING: Only a qualified service technician should service and

repair heater. Make sure that power is turned off before proceeding.

Turn off and let cool before servicing.

IMPORTANT: Operating heater where impurities in air exist may create odors. Cleaning sup-

plies, paint, paint remover, cigarette smoke, cements and glues, new carpet or textiles, etc.,

create fumes. These fumes may mix with combustion air and create odors.

Note: All troubleshooting items are listed in order of operation.

Problem

Using natural gas and

pilot will not light.

Pressure Switch

When using natural gas (NG), there is a

pressure switch that acts to turn off the gas

flow to the pilot if the inlet pressure exceeds

9.5" WC. This is to prevent the operation of

the unit on the wrong gas (propane). If your

natural gas supply exceeds 9.5" WC the unit

will not operate. Either contact your gas sup-

plier to check and adjust the inlet pressure or

a qualified service technician can bypass the

pressure switch.

Before attempting to bypass the pressure

switch, make sure the type of gas being used

is correct. Check to make sure the connection

fitting is in the correct inlet on the regulator.

Refer to Connecting to Gas Supply, page 14

Only a qualified installer should bypass the

pressure switch. To bypass the pressure

switch locate the set screw on the regulator.

Use a small flat bladed screw driver to turn the

set screw counterclockwise 2 turns. This will

bypass the pressure switch function.
