GAS SUPPLY

This vented room heater must be connected to a gas supply
capable of supplying the appliances full rated capacity.
Provide a 1/8 inch N.P.T. plugged tapping, accessible for
test gauge connection, immediately upstream of the gas
supply connection to the appliance.  The minimum inlet
pressure in the gas supply pipe should be 4.5” w.c. for
Natural Gas and 11.0” w.c. for Propane Gas, “for the
purpose of input adjustment”.  The maximum inlet pressure
in the gas supply pipe should never exceed 14” w.c. for
either Natural or Propane Gas.  The gas supply piping
should be sized in accordance with ANSI Z223.1 National
Fuel Gas Code.  The normal manifold pressure should be
3.5” w.c. for Natural Gas and 10.0” w.c. for Propane
Gas.

If the outlet pressure of the gas valve must be adjusted,
this should be done by a qualified serviceman using proper
tools and instruments.

Check all connections with soapy water for possible gas
leaks.  Never use a match, candle or other ignition source.
It is recommended that pipe compound which is resistant
to the action of liquefied petroleum gases be used.  Do
not use Teflon tape or Teflon impregnated compound.

The appliance and its individual shutoff valve must be
disconnected from the gas supply piping during any
pressure testing of that system at the test pressure in excess
of ½ psig.

The appliance must be isolated from the gas supply piping
by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig.

LOCATION AND SPEICAL

PRECAUTIONS

Due to high temperatures the appliance should be
located out of traffic and away from furniture and
draperies.

Children and adults should be alerted to the hazards
of high surface temperature and should stay away
to avoid burns or clothing ignition.

Young children should be carefully supervised when
they are in the same room as the appliance.

Clothing or other flammable material should not be
placed on or near the appliance.

Any safety screen, guard, or casing top removed
for servicing a room heater must be replaced prior
to operating the appliance.

Do not use this heater if any part has been under
water.  Immediately call a qualified service technician
to inspect the heater and to replace any part of the
control system and any gas control which has been
under water.

For purpose of identifying the sides of the heater.
When you are facing the front of the heater the right
side has the access door and the left side is solid.

If heater is installed in a residential garage, all burners
and pilot must be above 18”.  Locate or protect
heater so it cannot be damaged by a moving vehicle.
