STEP 3-B. GAS CONNECTION
This heater must be connected to a gas supply capable of supplying the 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.
GAS SUPPLY PIPE
Minimum Inlet Pressure
(For purpose of input adjustment):
Maximum Inlet Pressure
(Must NEVER Exceed):
Normal Manifold Pressure:
(Pre-set at the factory)
The gas supply piping should be sized in accordance
with ANSI Z223.1 National Fuel Gas Code.
If the outlet pressure of the gas valve must be adjusted, this
must be done by a qualified service technician 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 impreg-
nated compound.
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping during any pressure testing of that
system at 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.
